Overview of Problem Solving Method?Overview of Problem Solving Method?

A problem solving methodology is simply a A problem solving methodology is simply a framework or pathway for approaching a framework or pathway for approaching a problem and developing a solution as well as problem and developing a solution as well as reflecting and evaluating the solutionreflecting and evaluating the solution

Why teach problem solvingWhy teach problem solving

1.1. Gives a framework for problem solvers to Gives a framework for problem solvers to work through a difficult, ill-defined problemwork through a difficult, ill-defined problem

2.2. Helps to develop problem solving skillsHelps to develop problem solving skills

3.3. Helps them to “get started” or “get unstuck”Helps them to “get started” or “get unstuck”

4.4. Also provides a vehicle to require reflection Also provides a vehicle to require reflection or evaluation of the solutionor evaluation of the solution

5.5. ABET: “Graduates must demonstrate and ability to ABET: “Graduates must demonstrate and ability to identify, formulate and solve engineering problems.identify, formulate and solve engineering problems.

What does the data reveal?What does the data reveal?

Data for engineering students showed no significant change Data for engineering students showed no significant change in confidence in their ability to solve problems (despite in confidence in their ability to solve problems (despite having solved over 2500 “problems” during their 4 years) – having solved over 2500 “problems” during their 4 years) – WoodsWoods

Students receiving a seminar/instruction on problem Students receiving a seminar/instruction on problem solving did show increased confidence in ability to solve solving did show increased confidence in ability to solve problems and were less anxious about problemsproblems and were less anxious about problems
