How to Write a Solution

by Richard Rusczyk & Mathew Crawford

You've figured out the solution to the problem - fantastic! But you're not finished. Whether you are writing solutions for a competition, a journal, a message board, or just to show off for your friends, you must master the art of communicating your solution clearly. Brilliant ideas and innovative solutions to problems are pretty worthless if you can't communicate them. In this article, we explore many aspects of how to write a clear solution. Below is an index; each page of the article includes a sample 'How Not To' solution and 'How To' solution. One common theme you'll find throughout each point is that every time you make an experienced reader have to think to follow your solution, you lose.

As you read the 'How To' solutions, you may think some of them are overwritten. Indeed, some of them could be condensed. Some steps we chose to prove could probably be cited without proof. However, it is far better to prove too much too clearly than to prove too little. Rarely will a reader complain that a solution is too easy to understand or too easy on the eye.

One note of warning: many of the problems we use for examples are extremely challenging problems. Beginners, and even intermediate students, should not be upset if they have difficulty solving the problems on their own.

What is Problem Solving?

by Richard Rusczyk

I was invited to the Math Olympiad Summer Program (MOP) in the 10th grade. I went to MOP certain that I must really be good at math… In my five weeks at MOP, I encountered over sixty problems on various tests. I didn’t solve a single one. That’s right – I was 0-for-60+. I came away no longer confident that I was good at math. I assumed that most of the other kids did better at MOP because they knew more tricks than I did. My formula sheets were pretty thorough, but perhaps they were missing something. By the end of MOP, I had learned a somewhat unsettling truth. The others knew fewer tricks than I did, not more. They didn’t even have formula sheets!

At another contest later that summer, a younger student, Alex, from another school asked me for my formula sheets. In my local and state circles, students’ formula sheets were the source of knowledge, the source of power that fueled the top students and the top schools. They were studied, memorized, revered. But most of all, they were not shared. But when Alex asked for my formula sheets I remembered my experience at MOP and I realized that formula sheets are not really math. Memorizing formulas is no more mathematics than memorizing dates is history or memorizing spelling words is literature. I gave him the formula sheets. (Alex must later have learned also that the formula sheets were fool’s gold – he became a Rhodes scholar.)

The difference between MOP and many of these state and local contests I participated in was the difference between problem solving and what many people call mathematics. For these people, math is a series of tricks to use on a series of specific problems. Trick A is for Problem A, Trick B for Problem B, and so on. In this vein, school can become a routine of ‘learn tricks for a week – use tricks on a test – forget most tricks quickly.’ The tricks get forgotten quickly primarily because there are so many of them, and also because the students don’t see how these ‘tricks’ are just extensions of a few basic principles.

I had painfully learned at MOP that true mathematics is not a process of memorizing formulas and applying them to problems tailor-made for those formulas. Instead, the successful mathematician possesses fewer tools, but knows how to apply them to a much broader range of problems. We use the term “problem solving” to distinguish this approach to mathematics from the ‘memorize-use-forget’ approach.

After MOP I relearned math throughout high school. I was unaware that I was learning much more. When I got to Princeton I enrolled in organic chemistry. There were over 200 students in the course, and we quickly separated into two groups. One group understood that all we would be taught could largely be derived from a very small number of basic principles. We loved the class – it was a year long exploration of where these fundamental concepts could take us. The other, much larger, group saw each new destination not as the result of a path from the building blocks, but as yet another place whose coordinates had to be memorized if ever they were to visit again. Almost to a student, the difference between those in the happy group and those in the struggling group was how they learned mathematics. The class seemingly involved no math at all, but those who took a memorization approach to math were doomed to do it again in chemistry. The skills the problem solvers developed in math transferred, and these students flourished.

We use math to teach problem solving because it is the most fundamental logical discipline. Not only is it the foundation upon which sciences are built, it is the clearest way to learn and understand how to develop a rigorous logical argument. There are no loopholes, there are no half-truths. The language of mathematics is precise, as is ‘right’ and ‘wrong’ (or ‘proven’ and ‘unproven’). Success and failure are immediate and indisputable; there isn’t room for subjectivity. This is not to say that those who cannot do math cannot solve problems. There are many paths to strong problem solving skills. Mathematics is the shortest.

Problem solving is crucial in mathematics education because it transcends mathematics. By developing problem solving skills, we learn not only how to tackle math problems, but also how to logically work our way through any problems we may face. The memorizer can only solve problems he has encountered already, but the problem solver can solve problems she’s never seen before. The problem solver is flexible; she can diversify. Above all, she can create.

Tips For New Math Teachers

by Gisele Glosser
Try not to frown on wrong answers. It discourages students from participating. Critical thinking and honest effort are more important than correct answers.
There is no teaching without control of your class. It is better to fall behind by a day or two early in the year to address discipline, than to have an uphill battle all year long over behavior.
Avoid talking over your students. If there is too much noise in the classroom, sometimes the best thing to do is to stop talking. (I am famous for the "Glosser Glare".)
Routine and structure are good, but too much of it can cause you and your class to fall into a rut. Try to vary activities from time to time.
Encourage active participation from your students. From time to time, call students to the board, or allow them to work in groups. Avoid giving teacher-directed lessons all of the time. (See our article on Cooperative Learning Techniques.)
Try to be flexible. Math can be a rigid topic, but you don't have to be. For example, I have a strict rule against chewing gum. But I close my eyes to it during a test.
Try to spell out what topics will be on the test. Telling your students to "Study Chapter 6" is not enough, especially if they have poor study skills.
In some schools, math is the only subject where students are grouped by ability (i.e. homogeneously). This makes it stand out more than other subjects. Parents may frequently ask: "Why didn't Johnny get an A in math? He got one in all his other subjects." Some parents may insist that their child be placed in the top math group, even when the child does not belong there.
It is important to get support from an administrator when it comes to difficult issues such as math groupings. Ask that they be present at conferences with difficult parents.
If a student was present for all the material taught, but is absent on the day of the test, then on the day the student returns, inform him/her of the make-up day and time. Don't let it go more than a day or two. However, if the student missed part or all of the material taught, you should give him a deadline by which to make up all missed work, and a new test date. It may be helpful to contact the parent in this case. A student should not be penalized for being absent. However, they can be penalized for failing to make up missed work.
I recommend a technique called "Front Loading". Students are most motivated to learn at the beginning of the school year. Rather than reviewing material from the previous school year, why not introduce a topic they haven't seen before?
Try to teach students good problem-solving skills. When your students enter the work place, their superiors will not give them a worksheet with 25 least common multiple (LCM) exercises. They will more likely have a scheduling problem that needs to be solved using LCM concepts.
To motivate students, give out awards for both good academics and for good effort.
Do your best to be fair to students. You will earn their respect this way.
The best motivator of all is connecting math to the real world. For example, when teaching the metric system, have students bring in empty cartons and bottles from their kitchen.

Test Anxiety by Virginia W. Strawderman, Ph.D.

Test Anxiety (the following information is loosely based on that of John Zbornik and Ellen Freedman)

Two major components seem to comprise test anxiety.

The cognitive aspect centers on worry which may include poor self-image, feelings of failure, or catastrophic thoughts.

The emotional aspects center on somatic disturbances such as stomach upset and headaches. Symptoms of nervousness such as shaking hands, sweating palms, dry mouth, shallow breathing, heart palpitations, and elevated blood pressure may also be present.

Behavioral responses may vary from focusing on one item, "checking out," hyper sensitivity to noise or other environmental stimuli, and "freezing up."

Assessing test anxiety should include, but not be limited to, getting a history from the student and parents, teachers, etc. and using rating scales.


Test Anxiety Assessment (based somewhat on John Zbornik’s work)

  1. What kinds of things happen in your body while you are taking a test?
  2. How is your breathing?
  3. How does your stomach feel?
  4. How does your head feel?
  5. Are you able to study the night before a test?
  6. How nervous do you feel when starting at test?
  7. Does the level of nervousness change and you progress through the test? How?
  8. Does your mind ever just go blank before or during a test?
  9. Even when you have studied a lot, do you still get nervous?
  10. Do you sometimes get stuck on a question or problem and can’t go on?
  11. Do you have trouble finishing tests?
  12. Does the subject matter of the test make a difference in your feelings while you are taking the test?
  13. What kind of things do you think about when you are taking a test?
  14. What thoughts go through your mind?

After a student has answered questions that are consistent with test anxiety, the next step is to help the student try to deal with the response.

[Note: The above questionnaire, with room for responses, can be printed here. .]


Suggestions to help students cope with math test anxiety

Teach students how to study for math tests by making note cards, working problems from classwork, homework, tests and quizzes.

Help students construct practice exams or practice tests that are available in books or through teachers.

Use other means to help the student "desensitize" by practicing test-like conditions.

Give positive reinforcement for good work and gentle correction for mistakes.

Teach students how to work backwards and/or eliminate answers on multiple-choice tests.

Help students practice doing the questions or problems in three waves: Easy, medium, and hard so they can maximize the time allowed.

Teach students about the physiology of test anxiety and to not be distracted by body responses.

Instruct students to eat meals with both carbohydrates and protein prior to the test.

Instruct students to try to exercise just enough to become a little bit tired prior to entering the testing situation (It lessens the affect of adrenaline caused by anxiety).

Help the students learn to have productive self-talk (rather than destructive self-talk).

"My job is to do the best I can on this test today."

Help students increase their ability to focus on the task of taking the test and every time attention wanders to refocus.

Teaching Values Through A Problem Solving Approach to Mathematics

by Margaret Taplin
Institute of Sathya Sai Education, Hong Kong

For many reasons, the state of society has reached a stage where it is more critical than ever to educate people in the traditional values of their culture. In recent years there has been considerable discussion about whether it is the responsibility of schools to impart values education. There is growing pressure for all teachers to become teachers of values, through modelling, discussing and critiquing values-related issues.
There are many opportunities to teach the principles of values education through existing subjects and topics. The purpose of this article is to suggest one of the many ways in which values education can be incorporated into existing mathematics curricula and approaches to teaching mathematics. In particular, it will focus on ways in which values education can be enhanced by utilising a problem-solving approach to teaching mathematics. The articles include quotations, printed in italics, from the Sathya Sai Education in Human Values program, which originated in India and is now active in more than 40 countries around the world.
These quotations are concerned with the following values:
  • equipping students to meet the challenges of life
  • developing general knowledge and common sense
  • learning how to be discriminating in use of knowledge, that is to know what knowledge is appropriate to use for what purposes
  • integrating what is learned with the whole being
  • arousing attention and interest in the field of knowledge so it will be mastered in a worthy way

Why Can Values be Enhanced by Teaching Mathematics via Problem Solving?
Increasing numbers of individuals need to be able to think for themselves in a constantly changing environment, particularly as technology is making larger quantities of information easier to access and to manipulate. They also need to be able to adapt to unfamiliar or unpredictable situations more easily than people needed to in the past. Teaching mathematics encompasses skills and functions which are a part of everyday life.
Examples:
  • reading a map to find directions
  • understanding weather reports
  • understanding economic indicators
  • understanding loan repayments
  • calculating whether the cheapest item is the best buy

Presenting a problem and developing the skills needed to solve that problem is more motivational than teaching the skills without a context. It allows the students to see a reason for learning the mathematics, and hence to become more deeply involved in learning it. Teaching through problem solving can enhance logical reasoning, helping people to be able to decide what rule, if any, a situation requires, or if necessary to develop their own rules in a situation where an existing rule cannot be directly applied. Problem solving can also allow the whole person to develop by experiencing the full range of emotions associated with various stages of the solution process.
Examples:
  • The problem that we worked on today had us make a hypothesis. Through testing, our hypothesis was proven incorrect. The problem solving approach allowed our group to find this out for ourselves, which made the "bitter pill" of our mistake easier to follow.
  • I found this activity to be quite a challenge. I felt intimidated because I could not see an immediate solution,and wanted to give up. I was gripped by a feeling of panic. I had to read the question many times before I understood what I had to find. I really had to "dig down" into the depths of my memory to recall the knowledge I needed to solve the problem.
  • Seeing patterns evelop before my own eyes was a powerful experience: it had a stimulating effect. I felt that I had to explore further in a quest for an answer, and for more knowledge.

Extracts from a student teacher's journal after three separate problem solving sessions


The student who wrote the extracts above, has illustrated how interest rooted in the problem encouraged steady interest needed to master worthy knowledge. Experience with problem solving can develop curiosity, confidence and open-mindedness.


How To Teach Human Values By Incorporating Problem Solving Into The Mathematics Program.
This section will describe the types of problem solving which can be used to enhance the values described above, and will give some suggestions of how it can be used in the mathematics program.
There are three types of problems to which students should be exposed:
  1. word problems, where the concept is embedded in a real-world situation and the student is required to recognise and apply the appropriate algorithm/rule (preparing pupils for the challenges of life)
  2. non-routine problems which require a higher degree of interpretation and organisation of the information in the problem, rather than just the recognition and application of an algorithm (encouraging the development of general knowledge and common sense)
  3. "real" problems, concerned with investigating a problem which is real to the students, does not necessarily have a fixed solution, and uses mathematics as a tool to find a solution (engaging pupils in service to society).

Each of these problem types will be described in more detail below.


Problems which require the direct use of a mathematics rule or concept.
By solving these types of problems, students are learning to discriminate what knowledge is required for certain situations, and developing their common sense. The following examples have been adapted from the HBJ Mathematics Series, Book 6, to show how values such as sharing, helping and conserving energy can be included in the wording of the problems. They increase in difficulty as they require more steps:
Examples:
  • 7 children went mushrooming and agreed to share. They picked 245 mushrooms. How will they find out how many they will get each?
  • Nick helps his elderly neighbour for 1/4 of an hour every week night and for 1/2 an hour at the weekend. How much time does he spend helping her in 1 week?
  • Recently it was discovered that a clean engine uses less fuel. An aeroplane used 4700 litres of fuel. After it was cleaned it was found to use 4630 litres for the same trip. If fuel cost 59 cents a litre, how much more economical is the clean plane?
Sometimes it is important to give problems which contain too much information, so the pupils need to select what is appropriate and relevant:
Example:
Last week I travelled on a train for a distance of 1093 kilometres. I left at 8 a.m. and averaged 86 km/hour for the first four hours of the journey. The train stopped at a station for 1 1/2 hours and then travelled for another three hours at an average speed of 78 km/hour before stopping at another station. How far had I travelled?

To be able to solve these problems, the pupils cannot just use the bookish knowledge which they have been taught. They also need to apply general knowledge and common sense.
Another type of problem, which will encourage pupils to be resourceful, is that which does not give enough information. These problems are often called Fermi problems, named after the mathematician who made them popular. When people first see a Fermi problem they immediately think they need more information to solve it. Basically though, common sense and experience can allow for reasonable solutions. The solution of these problems relies totally on knowledge and experience which the students already have. They are problems which are non-threatening, and can be solved in a co-operative environment. These problems can be related to social issues, for example:
Examples:
  • How many liters of petrol are consumed in your town in a day?
  • How much money would the average person in your town save in a year by walking instead of driving or taking public transport?
  • How much food is wasted by an average family in a week?

Using a Fermi Problem to Promote Human Values
Ms. Lam wanted to teach her class of ten-year-olds about the value of money, and to appreciate what their parents were doing for them:
"I believe that students should be aware of this important issue and thus can be more considerate when a money issue raised in their own family, such as failure to persuade their parents to buy an expensive present. In solving the problems, I think that students can have a better understanding of the concept of money, not simply as a tool of buying and selling things.
"First I told the class a story about Peter's argument with his family. Peter failed to persuade his parents to buy expensive sportshoes as his birthday present and thought that his parents did not treat him well. The parents also felt upset as they regarded this son as an inconsiderate child. They thought that he should understand that the economy is not so good. They asked Peter if he knew about how much money was being spent on him throughout the whole year. Unfortunately, Peter could not produce the answer immediately. So I asked the class if they could help Peter. I asked them to find answers to the following problems:
  • How much money do your parents spend on you in a year?
  • How much money have your parents spent on you up till now?
  • How much money will your parents have spent on you by the time you finish secondary school?
  • How much money will be spent on raising children in the whole country this year?
"The students were formed into groups of 4 to find out the possible data that they need to know. Later, the groups were asked to present their data and the way of finding out the answer. Finally, I concluded that this is an open question as each person may have different expenditure along with some common human basic needs such as food, clothes and travelling fares. Anyway, the answer should be regarded as a large sum of money and thus give them a better understanding of their parents' burden."

Sometimes pupils can be asked to make up their own problems, which can help to enhance their understanding. This can encourage them to be flexible, and to realise that there can be more than one way of looking at a problem. Further, the teacher can set a theme for the problems that the pupils make up, such as giving help to others or concern for the environment, which can help them to focus on the underlying values as well as the mathematics.

Non-Routine Problems
Non-routine problems can be used to encourage logical thinking, reinforce or extend pupils' understanding of concepts, and to develop problem-solving strategies which can be applied to other situations. The following is an example of a non-routine problem:
What is my mystery number?
  • If I divide it by 3 the remainder is 1.
  • If I divide it by 4 the remainder is 2.
  • If I divide it by 5 the remainder is 3.
  • If I divide it by 6 the remainder is 4.

Real Problem Solving
Bohan, Irby and Vogel (1995) suggest a seven-step model for doing research in the classroom, to enable students to become "producers of knowledge rather than merely consumers" (p.256).

Step 1: What are some questions you would like answered.
The students brainstorm to think of things they would like to know, questions they would like to answer, or problems that they have observed in the school or community. Establish a rule that no one is to judge the thoughts of another. If someone repeats an idea already on the chalkboard, write it up again. Never say, "We already said that," as this type of response stifles creative thinking.
Step 2: Choose a problem or a research question.
The students were concerned with the amount of garbage produced in the school cafeteria and its impact on the environment. The research question was, "What part of the garbage in our school cafeteria is recyclable?"
Step 3: Predict what the outcome will be.
Step 4: Develop a plan to test your hypothesis
The following need to be considered:
  • Who will need to give permission to collect the data?
  • Courtesy - when can we conveniently discuss this project with the cafeteria manager?
  • Time - how long will it take to collect the data?
  • Cost - will it cost anything?
  • Safety - what measures must we take to ensure safety?
Step 5: Carry out the plan:
Collect the data and discuss ways in which the students might report the findings (e.g. graphs)
Step 6: Analyse the data: did the test support our hypothesis?
What mathematical tools will be needed to analyse the data: recognising the most suitable type of graph; mean; mode; median?
Step 7: Reflection
What did we learn? Will our findings contribute to our school, our community, or our world? How can we share our findings with others? If we repeated this experiment at another time, or in another school, could we expect the same results? Why or why not? Who might be interested in our results?
"The final thought to leave with students is that they can be researchers and producers of new information and that new knowledge can be produced and communicated through mathematics. Their findings may contribute to the knowledge base of the class, the school, the community, or society as a whole. Their findings may affect their school or their world in a very positive way" (Bohan et al., 1995, p.260).

Mathematical Investigations
Mathematical investigations can fit into any of the above three categories. These are problems, or questions, which often start in response to the pupils' questions, or questions posed by the teacher such as, "Could we have done the same thing with 3 other numbers?", or, "What would happen if...." (Bird, 1983). At the beginning of an investigation, the pupils do not know if there will be a suitable answer, or more than one answer. Furthermore, the teacher either does not know the outcome, or pretends not to know. Bird suggests that an investigation approach is suitable for many topics in the curriculum and encourages communication, confidence, motivation and understanding as well as mathematical thinking. The use of this approach makes it difficult for pupils to just carry out routine tasks without thinking about what they are doing.
Bird believes that investigational problem solving can be enhanced if students are encouraged to ask their own questions. She suggested that the teacher can introduce a "starter" to the whole class, ask the students to work at it for a short time, ask them to jot down any questions which occurred to them while doing it, and pool ideas. Initially it will be necessary for the teacher to provide some examples of "pooled" questions, for example:
  • Does it always work?
  • Is there a reason for this happening?
  • How many are there?
  • Is there any connection between this and.....?
The pupils can be invited to look at each other's work and, especially if they have different answers, to discuss "who is right".

Conclusion
This article has suggested some reasons why problem solving is an important vehicle for educating students for life by promoting interest, developing common sense and the power to discriminate. In particular, it is an approach which encourages flexibility, the ability to respond to unexpected situations or situations that do not have an immediate solution, and helps to develop perseverance in the face of failure. A problem-solving approach can provide a vehicle for students to construct their own ideas about mathematics and to take responsibility for their own learning. While these are all important mathematics skills, they are also important life skills and help to expose pupils to a values education that is essential to their holistic development.

Some Questions For Discussion With Colleagues, or Action Research In Your Classroom

Supervising Your Child's Homework

by Gisele Glosser
During the many conferences I have had over the years, homework is often mentioned as a troublesome area for parents and students alike. Here are some suggestions for supervising your child's homework, organized by category. These suggestions stem from my math teaching experience; however, most of them will work for other subject areas, too.
Expectations
Set aside a specific time and place to do homework each day.
Some children concentrate better with music or background noise.
Define consequences for undone homework before it happens.
You may want to create a homework contract with your child that clearly spells out rules.
Supervision
Check your child's assignment book, planner, or agenda for assignments, projects and tests.
Don't try to be an expert in every subject area. Just supervise.
Encourage completeness of answers (full sentences, units of measure, etc.).
Encourage labeling of homework with textbook page numbers, dates, etc.
Organization
Schedule study time for tests well in advance.
Plan out and start long-term projects well before they are due.
Organize notebooks by subject and chronologically within a subject.
Choose a set location for storing homework, books and supplies.
Absence
Have your child choose a study buddy to work with.
Make up assignments as soon as possible.
If the absence is extended, notify the school.
If a serious family emergency occurs, notify the school.

Mathematics Through Problem Solving

by Margaret Taplin
Institute of Sathya Sai Education, Hong Kong

What Is A 'Problem-Solving Approach'?
As the emphasis has shifted from teaching problem solving to teaching via problem solving (Lester, Masingila, Mau, Lambdin, dos Santon and Raymond, 1994), many writers have attempted to clarify what is meant by a problem-solving approach to teaching mathematics. The focus is on teaching mathematical topics through problem-solving contexts and enquiry-oriented environments which are characterised by the teacher 'helping students construct a deep understanding of mathematical ideas and processes by engaging them in doing mathematics: creating, conjecturing, exploring, testing, and verifying' (Lester et al., 1994, p.154). Specific characteristics of a problem-solving approach include:
  • interactions between students/students and teacher/students (Van Zoest et al., 1994)
  • mathematical dialogue and consensus between students (Van Zoest et al., 1994)
  • teachers providing just enough information to establish background/intent of the problem, and students clarifing, interpreting, and attempting to construct one or more solution processes (Cobb et al., 1991)
  • teachers accepting right/wrong answers in a non-evaluative way (Cobb et al., 1991)
  • teachers guiding, coaching, asking insightful questions and sharing in the process of solving problems (Lester et al., 1994)
  • teachers knowing when it is appropriate to intervene, and when to step back and let the pupils make their own way (Lester et al., 1994)
  • A further characteristic is that a problem-solving approach can be used to encourage students to make generalisations about rules and concepts, a process which is central to mathematics (Evan and Lappin, 1994).
Schoenfeld (in Olkin and Schoenfeld, 1994, p.43) described the way in which the use of problem solving in his teaching has changed since the 1970s:

My early problem-solving courses focused on problems amenable to solutions by Polya-type heuristics: draw a diagram, examine special cases or analogies, specialize, generalize, and so on. Over the years the courses evolved to the point where they focused less on heuristics per se and more on introducing students to fundamental ideas: the importance of mathematical reasoning and proof..., for example, and of sustained mathematical investigations (where my problems served as starting points for serious explorations, rather than tasks to be completed).

Schoenfeld also suggested that a good problem should be one which can be extended to lead to mathematical explorations and generalisations. He described three characteristics of mathematical thinking:
  1. valuing the processes of mathematization and abstraction and having the predilection to apply them
  2. developing competence with the tools of the trade and using those tools in the service of the goal of understanding structure - mathematical sense-making (Schoenfeld, 1994, p.60).
  3. As Cobb et al. (1991) suggested, the purpose for engaging in problem solving is not just to solve specific problems, but to 'encourage the interiorization and reorganization of the involved schemes as a result of the activity' (p.187). Not only does this approach develop students' confidence in their own ability to think mathematically (Schifter and Fosnot, 1993), it is a vehicle for students to construct, evaluate and refine their own theories about mathematics and the theories of others (NCTM, 1989). Because it has become so predominant a requirement of teaching, it is important to consider the processes themselves in more detail.

The Role of Problem Solving in Teaching Mathematics as a Process
Problem solving is an important component of mathematics education because it is the single vehicle which seems to be able to achieve at school level all three of the values of mathematics listed at the outset of this article: functional, logical and aesthetic. Let us consider how problem solving is a useful medium for each of these.
It has already been pointed out that mathematics is an essential discipline because of its practical role to the individual and society. Through a problem-solving approach, this aspect of mathematics can be developed. Presenting a problem and developing the skills needed to solve that problem is more motivational than teaching the skills without a context. Such motivation gives problem solving special value as a vehicle for learning new concepts and skills or the reinforcement of skills already acquired (Stanic and Kilpatrick, 1989, NCTM, 1989). Approaching mathematics through problem solving can create a context which simulates real life and therefore justifies the mathematics rather than treating it as an end in itself. The National Council of Teachers of Mathematics (NCTM, 1980) recommended that problem solving be the focus of mathematics teaching because, they say, it encompasses skills and functions which are an important part of everyday life. Furthermore it can help people to adapt to changes and unexpected problems in their careers and other aspects of their lives. More recently the Council endorsed this recommendation (NCTM, 1989) with the statement that problem solving should underly all aspects of mathematics teaching in order to give students experience of the power of mathematics in the world around them. They see problem solving as a vehicle for students to construct, evaluate and refine their own theories about mathematics and the theories of others.
According to Resnick (1987) a problem-solving approach contributes to the practical use of mathematics by helping people to develop the facility to be adaptable when, for instance, technology breaks down. It can thus also help people to transfer into new work environments at this time when most are likely to be faced with several career changes during a working lifetime (NCTM, 1989). Resnick expressed the belief that 'school should focus its efforts on preparing people to be good adaptive learners, so that they can perform effectively when situations are unpredictable and task demands change' (p.18). Cockcroft (1982) also advocated problem solving as a means of developing mathematical thinking as a tool for daily living, saying that problem-solving ability lies 'at the heart of mathematics' (p.73) because it is the means by which mathematics can be applied to a variety of unfamiliar situations.
Problem solving is, however, more than a vehicle for teaching and reinforcing mathematical knowledge and helping to meet everyday challenges. It is also a skill which can enhance logical reasoning. Individuals can no longer function optimally in society by just knowing the rules to follow to obtain a correct answer. They also need to be able to decide through a process of logical deduction what algorithm, if any, a situation requires, and sometimes need to be able to develop their own rules in a situation where an algorithm cannot be directly applied. For these reasons problem solving can be developed as a valuable skill in itself, a way of thinking (NCTM, 1989), rather than just as the means to an end of finding the correct answer.
Many writers have emphasised the importance of problem solving as a means of developing the logical thinking aspect of mathematics. 'If education fails to contribute to the development of the intelligence, it is obviously incomplete. Yet intelligence is essentially the ability to solve problems: everyday problems, personal problems ... '(Polya, 1980, p.1). Modern definitions of intelligence (Gardner, 1985) talk about practical intelligence which enables 'the individual to resolve genuine problems or difficulties that he or she encounters' (p.60) and also encourages the individual to find or create problems 'thereby laying the groundwork for the acquisition of new knowledge' (p.85). As was pointed out earlier, standard mathematics, with the emphasis on the acquisition of knowledge, does not necessarily cater for these needs. Resnick (1987) described the discrepancies which exist between the algorithmic approaches taught in schools and the 'invented' strategies which most people use in the workforce in order to solve practical problems which do not always fit neatly into a taught algorithm. As she says, most people have developed 'rules of thumb' for calculating, for example, quantities, discounts or the amount of change they should give, and these rarely involve standard algorithms. Training in problem-solving techniques equips people more readily with the ability to adapt to such situations.
A further reason why a problem-solving approach is valuable is as an aesthetic form. Problem solving allows the student to experience a range of emotions associated with various stages in the solution process. Mathematicians who successfully solve problems say that the experience of having done so contributes to an appreciation for the 'power and beauty of mathematics' (NCTM, 1989, p.77), the "joy of banging your head against a mathematical wall, and then discovering that there might be ways of either going around or over that wall" (Olkin and Schoenfeld, 1994, p.43). They also speak of the willingness or even desire to engage with a task for a length of time which causes the task to cease being a 'puzzle' and allows it to become a problem. However, although it is this engagement which initially motivates the solver to pursue a problem, it is still necessary for certain techniques to be available for the involvement to continue successfully. Hence more needs to be understood about what these techniques are and how they can best be made available.
In the past decade it has been suggested that problem-solving techniques can be made available most effectively through making problem solving the focus of the mathematics curriculum. Although mathematical problems have traditionally been a part of the mathematics curriculum, it has been only comparatively recently that problem solving has come to be regarded as an important medium for teaching and learning mathematics (Stanic and Kilpatrick, 1989). In the past problem solving had a place in the mathematics classroom, but it was usually used in a token way as a starting point to obtain a single correct answer, usually by following a single 'correct' procedure. More recently, however, professional organisations such as the National Council of Teachers of Mathematics (NCTM, 1980 and 1989) have recommended that the mathematics curriculum should be organized around problem solving, focusing on:
(i) developing skills and the ability to apply these skills to unfamiliar situations
(ii) gathering, organising, interpreting and communicating information
(iii) formulating key questions, analyzing and conceptualizing problems, defining problems and goals, discovering patterns and similarities, seeking out appropriate data, experimenting, transferring skills and strategies to new situations
(iv) developing curiosity, confidence and open-mindedness (NCTM, 1980, pp.2-3).

One of the aims of teaching through problem solving is to encourage students to refine and build onto their own processes over a period of time as their experiences allow them to discard some ideas and become aware of further possibilities (Carpenter, 1989). As well as developing knowledge, the students are also developing an understanding of when it is appropriate to use particular strategies. Through using this approach the emphasis is on making the students more responsible for their own learning rather than letting them feel that the algorithms they use are the inventions of some external and unknown 'expert'. There is considerable importance placed on exploratory activities, observation and discovery, and trial and error. Students need to develop their own theories, test them, test the theories of others, discard them if they are not consistent, and try something else (NCTM, 1989). Students can become even more involved in problem solving by formulating and solving their own problems, or by rewriting problems in their own words in order to facilitate understanding. It is of particular importance to note that they are encouraged to discuss the processes which they are undertaking, in order to improve understanding, gain new insights into the problem and communicate their ideas (Thompson, 1985, Stacey and Groves, 1985).

Conclusion
It has been suggested in this chapter that there are many reasons why a problem-solving approach can contribute significantly to the outcomes of a mathematics education. Not only is it a vehicle for developing logical thinking, it can provide students with a context for learning mathematical knowledge, it can enhance transfer of skills to unfamiliar situations and it is an aesthetic form in itself. A problem-solving approach can provide a vehicle for students to construct their own ideas about mathematics and to take responsibility for their own learning. There is little doubt that the mathematics program can be enhanced by the establishment of an environment in which students are exposed to teaching via problem solving, as opposed to more traditional models of teaching about problem solving. The challenge for teachers, at all levels, is to develop the process of mathematical thinking alongside the knowledge and to seek opportunities to present even routine mathematics tasks in problem-solving contexts.

Math through Technology

by Sasha Orman

When you think of "technology," many applications may pop into your head, but "teaching tool" may not necessarily be one of them. Why is this? Perhaps it's because of its newness, but technology in the classroom should not be shied away from. To the contrary, it can be one of the most effective teaching tools available.

Educate Your Students By Gaining Their Interest

Students these days are subjected to a barrage of fast-paced mental stimulation, from music videos to video games. Too many teachers see these as hopeless competition, when really they could be using the same techniques to grab students' attention and teach them something at the same time. Textbooks may be the backbone of the classes you teach - it is hard to do otherwise, really - but by no means must they be the only source of learning.

  • Getting your students active and working together is your best avenue toward getting them interested. Technology is a great tool for this: not only will your students have a more vivid memory of their math lessons, but they will be learning a slew of technical skills as well. Send your class on WebQuests for research. Instead of poster-board team projects, why not have them construct a PowerPoint presentation? Take them to the school's computer lab to check out math-related podcasts. (If your classroom has individual computer, so much the better!) Engaging your students and keeping them active will really make your lessons memorable, and teach new skills to boot!
  • Mix things up! If you only stick to one variation of interaction, it will become just as much of a routine as textbooks in no time flat. Play a math game with your students one day, and play them some math music the next. Every day can’t be extra-special (those chapter tests have to come sometime), but your students will treasure the times when they are.

Educate Your Students by Educating Yourself

Perhaps the greatest thing about technology is how, by definition, it is forever changing and evolving. However, as technology changes, you have to be prepared to keep up with it. Luckily, there are many different resources available to teachers for honing and upkeep of your tech-savvy skills.

  • One of your biggest allies is the internet -- take this very site, for example! Many educational resources you already trust have online outlets these days. PBS is a shining example, with an assortment of ideas and sources to supplement your lesson plans at any specific topic or grade level grouping.
  • If you find yourself growing bored at your own lessons, then perhaps you need a little more than just some website suggestions. In fact, a refresher course of even a new degree may be in order. Of course, these days you don't have to give up your teaching career while you get an education of your own! Many online teaching universities offer instructional technology degrees to bring you up to date on cutting-edge learning theory and all the latest in software and multimedia (and how it best fits in with your curricula!), and best of all, you can take the classes on your own time and even work new ideas into your current lesson plans!

Math Anxiety Model by Virginia W. Strawderman, Ph.D.

What is Math Anxiety?

Tobias (1978) described it as "sudden death" (p. 46), but Kogelman and Warren (1979) say it is an adverse reaction to mathematics, while Byrd (1982) says it is any situation when one experiences anxiety "when confronted with mathematics in any way" (p. 38)

The developers of the MARS (Math Anxiety Rating Scale) say it "involves feelings of tension and anxiety that interfere with the manipulation of numbers and the solving of mathematical problems in a wide variety of ordinary and academic situations" Richardson and Suinn, 1972, p.551).

Why not other subject anxiety?

This may more particularly true of the study of mathematics because "mathematics offers what is perhaps the clearest and most concentrated example" of intelligent learning, "which is to say the formation of conceptual structures communicated and manipulated by means of symbols" (Skemp, 1971, p.16).

The Domains and Continua of the Model

There appear to be three major domains which are involved with the development of math anxiety. There is naturally some overlap between and among them and their boundaries are not well defined. In order to facilitate the development of this model of math anxiety, the domains will be treated as though they are distinct and well defined.

Associated with each domain is a continuum on which it is assumed that any student at any particular time may be found. The extremes of the continua are given and discussed below. The color codes associate each continuum with its appropriate Domain.

The Social / Motivational Domain includes those forces that act upon a person through the agencies of family, friends, and society as a whole. The continuum associated with this domain is Behavior because although choices are influenced by others, they are ultimately made by the individual. The Behavior Continuum has Pursuit and Avoidance as its opposites. These behaviors are logical consequences of the value place on mathematics, which is influenced by the attitudes of significant others and by society in general.

The Intellectual / Educational Domain is comprised of those influences that are cognitive in nature. Specifically, they include but are not limited to, the knowledge and skills an individual has and or is expected to acquire and his or her perception of success or failure in them. Although others may "grade" an individual’s performance in this domain, people form their own evaluations of their performance in this area. The continuum associated with this domain is Achievement, where individual perception is paramount. Success and Failure are the extremes of the Achievement Continuum, and are the subjective evaluation regarding one’s acquisition or use of mathematics skill and concepts.

The Psychological / Emotional Domain is formed by the faculties that are affective in nature. It is largely comprised of the individual’s emotional history, reactions to stimuli and arousal states. Hence the continuum associated with this domain is Feelings. At either end of the Feelings Continuum lie Anxiety and Confidence, although it could be argued that enjoyment is even further removed from anxiety than confidence. The assumption is that most students would find it puzzling to think of mathematics as enjoyable. Confidence can be equated with comfortableness, rather than pleasure.

The extremes of the three continua comprise positive and negative cycles.

The three Domains are theorized to interact in a reinforcing fashion as illustrated by the cycles. In the following diagram.

In the Positive Cycle, an individual who is successful in the use and/or study of mathematics will be more confident in situation involving math and more likely to pursue the study or use of mathematics.

A similar relationship is theorized for both confidence and pursuit because a person who pursues the study of mathematics will tend to be more confident in math situations and will also tend to be more successful in its study and use. The latter is a logical assumption, for if one does not continue the study of mathematics, one cannot continue to be successful in learning it.

Research indicates that the more confidence a person has vis-à-vis mathematics, the more likely he or she is to be successful in such tasks (Betz, 1977, p.22), and the more confidence the individual has toward learning and using mathematics, the more likely he or she is to pursue its study.

The Negative Cycle operates in a similar way, with each component reinforcing the others. Failure in mathematics contributes is hypothesized to be an antecedent to math anxiety (Tobias & Weissbrod, 1980, p. 65). Since few people seek opportunities for failure, it is logical that avoiding mathematics would be a result of perceived or actual failure.

Anxiety reactions to mathematical situations may contribute to failure in mathematics (Tobias & Weissbrod, 1980, p.63). In fact, s person who has high math anxiety may actually be unable to perform well on test, and may be unable to learn in a mathematics classroom. Math anxiety also directly contributes to avoiding mathematics (Tobias & Weissbrod, 1980, p.63). It is logical to avoid situations which bring on anxiety reactions.

The ways in which avoidance contributes to failure and anxiety are perhaps a little less clear. Avoidance of mathematics engenders failure because a person who has successfully avoided mathematical situations for some time may lack the skills and knowledge needed when he or she is presented with a situation requiring its use. This is situation in which the individual is very likely to fail. Similarly, the person who has avoided mathematics and is suddenly confronted with a circumstance requiring it, is likely to be painfully aware of his or her lack of preparation and become anxious about it as a result. Thus the avoidance of mathematics can lead to failure and/or anxiety with staggering effect. Of course, if one could only continue to avoid mathematics situations, neither failure nor anxiety would result.

The phenomenon of math anxiety itself is of interest to the education community only because individuals find themselves placed in situation requiring that they either use or learn mathematics, or both. Without conditions necessitating the use of mathematics, math anxiety, however high the individual’s level, would not be of any consequence. An underlying assumption of this model is that math anxiety is of interest only to those people who have been influenced by it in the past, in career choices, for example, those who are influenced by it presently, as in a mathematics class, or those who will in influenced by it in the future, as in a required math class or job skill. As long as a perseon has no need for mathematics, math anxiety is unimportant.

The paths that people may travel in entering the Negative Cycle from the Positive Cycle may vary. This model was developed to illustrate the development of math anxiety, so the change from the Positive Cycle to the Negative Cycle will be our concern. Each Domain will be examined separately

Math Anxiety Dynamics

.In the Social / Motivational Domain movement along the Behavior Continuum from Pursuit to Avoidance can occur for many reasons. Sometimes it is a simple as students being extremely gifted in non-mathematical areas and choosing to spend their time and energy on the subject in which they are gifted. Individuals may also decide that the study or use of mathematics is not appropriate for them. This may be the result of sex-role stereotyping or other beliefs held by their socio-economic group.

The Intellectual / Educational Domain encompass the mostly academic influences on people. Many students move into the Negative Cycle through the Achievement Continuum when they no longer experience that they deem as success in the study of mathematics. Tobias asserted that "most people leave school as failures at math" (1978, p.26). Hilton (1980, p. 176) lists the causes of failure to be "bad teaching, bad texts, and bad educational instruments." He went on to include rote calculations, memory dependence, authoritarianism, spurious applications and unmotivated problems as additional factors which inhibit success in many students. Kogelman and Warren (1979) hypothesized that perceived rigidity of rules and an inordinate emphasis on right answers may drive some students, who are intellectually capable of learning mathematics from success to failure. In addition, the cumulative nature of mathematics may be a source of failure for students who must be absent from school for any length of time. Regardless of how or why individuals fail in mathematics, they often experience what Tobias (1978) calls "sudden death." Whether it was timed tests on multiplication facts, the introduction of operations fractions, multi-stage word problems, or solving equations that caused the difficulties, for many "failure was sudden and very frightening" (Tobias, 1978, p. 44). Presumably, students do not really just suddenly reach a concept or procedure that they cannot learn. In Lazarus’ (1974) analysis of math anxiety, he hypothesized a "latency stage" –a period in which the student has been relying on a memorize-what-to-do strategy in learning mathematics.

The Feelings Continuum is in the Psychological / Emotional Domain, with its extremes being Confidence and Anxiety. The transition from Confidence to Anxiety has been hypothesized to be the result of unpleasant experiences associated with learning or doing mathematics (Byrd, 1982; Kogelman & Warren, 1979; Tobias, 1978). Many people recall their first negative experiences with mathematics with surprising vividness and clarity. They may remember how the teacher looked or dressed and what type of mathematics task was involved. Students recollect mathematics being taught in an atmosphere of tension created by an emphasis on swift computations and correct answers (Tobias, 1978). Sometimes these negative experiences are not school related, but are associated with a parent or sibling who acts as tutor (Kogelman & Warren, 1979). In addition to these stresses, tests on mathematics serve as high stress producers. Kogelman & Warren (1979) found that mathematics "has long been associated with the pressures of performing and being evaluated" (p.58), and far too frequently, the associations are not pleasant ones. In short, movement from the Positive Cycle to the Negative Cycle can be precipitated by unpleasant emotions in a mathematics situation.

The model as presented thus far includes the influences that are chiefly affective in nature. What about cognitive variables? It is possible that they contribute strongly to the development of math anxiety. At the time this model was originally conceived and researched, there were no studies that directly addressed the role of cognition, specifically the role of understanding, with respect to the phenomenon called math anxiety. Cognition may be at the very heart of the matter.

In his foreword to Skemp’s The Psychology of Learning Mathematics, Foss stated that

mathematics is a curious subject, psychologically. It seems to divide people into two camps…there are those who can do mathematics and there are those who cannot, or who think they cannot, and who "block" at the first drop of a symbol. (cited in Skemp, 1971, p.9)

In fact, cognitive variables may have a greater impact than early research would indicate. Ashcraft and Kirk (2001) have been doing significant research in the area of how math anxiety may inhibit certain cognitive functions. They found that math anxiety may inhibit certain brain functions, possibly the very ones needed most for learning mathematics. So it is possible that math anxiety causes and is caused by failure to comprehend mathematics.

For the purposes of this model of math anxiety, however, learning will be examined with respect to its role in how people move between the Positive Cycle and the Negative Cycle. The Learning Continuum is hypothesized to have as its extremes Understanding and Rote Learning (listed as Rote).

That understanding and rote learning tend to be polar opposites in learning mathematics has long been understood. Carpenter et al., (1981) observed that students may concentrate on mastering rules to the extent of ignoring concomitant understanding, which means that they become totally dependent on mechanical algorithms, which are easily forgotten. "If students cannot remember a step in the algorithm, they cannot solve even simple problems that might be solved intuitively" (p.27). Learning by rote and learning with understanding are very different processes and have very different outcomes. There are important qualitative differences between students who have learned by rote and those who have learned with understanding (Simon, 1975; Skemp, 1971). Rote learners have difficulty applying learned skills in solving problems (Carpenter et al., 1981). In contrast, the "effects of understanding are cumulative; that is to say that "the greater the degree of understanding, the less the amount of practice necessary to promote and to fix learning" (Brownell, 1973, P.188), This may more particularly true of the study of mathematics because "mathematics offers what is perhaps the clearest and most concentrated example" of intelligent learning, "which is to say the formation of conceptual structures communicated and manipulated by means of symbols" (Skemp, 1971, p.16).

The following is a discussion of how the Learning Continuum fits with the other continua.

It is hypothesized that a mutually reinforcing relationship exists between understanding and the pursuit of mathematics learning. Students who understand the mathematics they are learning will be more likely to further pursue the subject. This may be because students who understand math may have a greater awareness of its usefulness and power, and pursue it for that reason. It may also be a result of the pleasure people experience from activities which are favorable to cognitive growth, which is "the most powerful incentive to leaning mathematics" (Skemp, 1971, p. 135). It is logical to assume that the pursuit of mathematics leads to understanding. Hartung (1953) asserted that increased motivation "may affect later learning experiences in ways which increase the level of achievement [understanding]" (p64).

It also seems obvious that understanding mathematics enhances one’s success in the subject. The reverse direction: that success leads to understanding may be a logical assumption, but some educators assert that it is not at all the case. Skemp (1971) states that "learning to manipulate symbols in such a way as to obtain the approved answer may be very hard to distinguish, in its early stages, from conceptual learning" (p. 51). In fact, the leaner "cannot distinguish between the two if he has no experience of understanding mathematics" (Skemp, p. 51). Consequently the arrowhead from success to understanding is omitted in this model.

Understanding should increase students’ confidence in studying mathematics. Confidence in mathematics may lead to greater understanding, but confidence based on one’s ability to memorize, which yields apparently successful learning is fraught with peril. Confidence that arises from true understanding of mathematical concepts and processes, on the other hand, does engender further understanding. This becomes a sort of loop in which understanding builds confidence which, in turn, gives students increased assurance that they can learn new mathematical concepts, which raises confidence, etc.

In the Negative Cycle just the reverse is true.

Rote learning often leads to avoidance

Visions of draconian teachers demanding insane memorization of meaningless mumbo-jumbo prevent a large number of people from reacting normally to the opportunities offered by contemporary mathematics. (Steen, 1978, p.2).

How avoidance of mathematics leads to rote learning is less obvious. If the student does not want to learn math, he or she may choose to just "try to learn what to do."

The relationship between rote learning and failure is obvious.

The amount which a bright child can memorize is remarkable, and the appearance of learning mathematics may be maintained until a level is reached at which only true conceptual learning is adequate to the situation. At this stage the learner tries to master the new tasks by the only means he knows--memorizing the rule for each kind of problem. This task being now impossible, even the outward appearance of progress ceases; and with accompanying distress, another pupil falls by the wayside. (Skemp, 1971, p.51)

Failure can lead to rote learning as the student attempts to master new material. Since he or she has experienced failure, perhaps the best thing is to try to "just learn what to do." Tobias (1978) described it as the penultimate solution.

Skemp (1971) cites rote learning as in initial cause of mathematics anxiety (p.129). Memorization must eventually produce anxiety because first, as mathematics becomes more advanced the number of routines to memorized places a serious burden on the memory and second, a routine works only for a limited range of problems. Memorizing produces a short-term effect but not long-term retention, "so further progress comes to a standstill, with anxiety and loss of self-esteem" (Skemp, 1971. p.130).This becomes a double bind because since "higher mental activities are the first to be adversely affected by situation anxiety" (p.126-127), the only alternative is rote leaning. Skemp goes on to suggest that because rote learning is often faster, it may be favored because it brings "quicker relief from anxiety" (p.133).

So when we put it all together, the Model of Math Anxiety looks like this:
