Problem Solving

Problem solving has been defined as “what you do when you don’t know what to do.” If you know what to do, it is not a problem, it is an exercise (Keller, 1993). We often give to our students tasks that we present as problems; however, we often explain to them how they should complete the task. When we outline the process for students, we take away the opportunity for them to use their actual skills in problem solving.

Problem solving is a hallmark of mathematical activity and a major means of developing mathematical knowledge. It is finding a way to reach a goal that is not immediately attainable. Problem solving is natural to young children because the world is new to them, and they exhibit curiosity, intelligence, and flexibility as they face new situations. (NCTM, 2000, p. 116)

Kolb (1984) and Polya (1971) both identify four stages of problem solving as follows:

The four stages of problem solving.

  1. Define the problem.
  2. Develop a procedure for solving the problem.
  3. Conduct the procedure.
  4. Draw conclusions.

One can enter and exit this cycle at any area depending on the task at hand. Problem solving is a necessary part of life. We are constantly put into predicaments in which we need to develop a solution. Why won’t my car start? How can I find enough money to buy a new car? Why won’t the rolls that I am baking rise like mother’s rolls? In each of these situations, the answer is not obvious. We have to make decisions about how we will solve the problem.

Traditional classrooms tend to approach student learning through predesigned procedures. Teachers explain to the students how they should answer each problem. In mathematics we explain the “correct” process for adding two numbers together. In science, we give students a step-by-step procedure that they need to follow if they are to develop the correct results. These practices cause children to feel uncomfortable when they are put in actual problem-solving situations. Having been taught specific processes that they are required to follow in classroom situations, students become unsure when they have to make decisions about how to go about solving this new problem. An example of this is the insecurity that many children feel when asked to do a science fair project. They are concerned that regardless of how they do their project, it will not be done in a way that the judge or teacher would consider correct. They have been “taught” that there is only one correct way to do it.

During early development, children are highly responsive to direction by any authority figure. If they are constantly directed on how they should do things, they will look for additional direction from an authority figure rather than try to go it on their own. If they are encouraged to explore and try doing things their own way, they will feel comfortable experimenting. This attitude is critical for their developing confidence in handling daily responsibilities. Even in adulthood, we see people who have little confidence. They feel uncomfortable being put in decision-making situations because they might not do it the “accepted” way.

Children look at problems differently when they are able to self-define them. The difference is ownership. The question that they are examining is their question. They thought of the question and they want to answer it. Questions raised by other people such as teachers tend to not be as interesting or as important. An important skill for teachers to develop is to encourage students to ask questions and to use students’ questions in leading classroom activities and projects. The Concept Explorations presented in this book give examples of activities in which children are encouraged to explore questions that they design and want to study.

Collecting and Organizing Data

Collecting and organizing data are basic thinking skills that relate directly to problem solving. In basic problem solving, the procedures that are developed often require the collection of information or data: “How high can the water rocket go?” “How many of the seeds germinate?” “How long does it take to run around the track?” These types of activities are important to the development of children because they require the students to collect and organize data.
