  What Is Problem Solving?   (Site not responding. Last check: 2007-10-03)
An incidental benefit is that often the very attempt to represent the problem explicitly forces a problem solver to be clear about what it is he or she is trying to do and about what stands in the way.
Metacognition is essential for any extended activity, especially problem solving, because the problem solver needs to be aware of the current activity and of the overall goal, the strategies used to attain that goal, and the effectiveness of those strategies.
First, we need to recognize when we are engaged in problem solving and accept as natural, normal, and expected the stepwise and discursive path toward a goal through the application of general and specific heuristics.

 Mathematics Through Problem Solving
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.
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.
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).

 Problem-solving
A problem is a situation which is experienced by an agent as different from the situation which the agent ideally would like to be in.
Problem states will generally involve objects, which are the elements of the situation that are invariant under actions, and properties or predicates, which are the variable attributes of the objects.
Problem representations are usually also models of the situation as experienced by the agent.

 Synthesis of Research on Problem Solving
However, constructivism is consistent with current cognitive theories of problem solving and mathematical views of problem solving involving exploration, pattern finding, and mathematical thinking (36,15,20); thus we urge that teachers and teacher educators become familiar with constructivist views and evaluate these views for restructuring their approaches to teaching, learning, and research dealing with problem solving.
Problem posing (3) and problem formulation (16) are logically and philosophically appealing notions to mathematics educators and teachers.
Problem solving as a method of teaching may be used to accomplish the instructional goals of learning basic facts, concepts, and procedures, as well as goals for problem solving within problem contexts.

 Research Sampler 4: Expert Problem Solvers
Problems can be routine textbook exercises or they can be difficult mathematical tasks which take weeks, months, or even years to solve.
Good problem solvers exhibit productive responses to insufficient understanding, while others, not wanting to admit deficiencies in their mathematical knowledge, may feel they "should" know and this may lead them to guess or use plausible, but inappropriate, procedures.
For example, if a positive pathway is invoked at the onset of problem solving, curiosity may motivate the solver to better understand the problem and lead to exploratory heuristics; frustration at a subsequent impasse can cause a revision of strategies.

 Success in Mathematics
Each problem of types 4 or 5 usually requires you to use a multi-step approach, and may involve several different math skills and techniques.
The first and most important step in solving a problem is to understand the problem, that is, identify exactly which quantity the problem is asking you to find or solve for (make sure you read the whole problem).
In the book each problem appears at the end of the section in which you learned how do to that problem; on a test the problems from different sections are all together.
