<p> PROBLEM SOLVING STRATEGY</p><p>The benefits of using a problem-solving strategy:</p><p> It provides a consistent methodology that can be used for all problems.  Its application shows the generality of problem solving as an activity.  It is an excellent means by which problem solvers can overcome the initial panic of “how can I ever solve that?’  It answers the question “What do I do next?”  It slows the process down: usually this helps make the problem solver be more accurate and methodical.  It provides a starting structure for identifying the parts of the problem.</p><p>Be WISE</p><p>WHAT’S HAPPENING Physical Principle Identify the basic physical principles involved in the problem. Construct a conceptual picture of the problem before you attempt to write equations.</p><p>Diagram Draw a sketch or diagram. Be reasonably accurate. It may lead to relationships that are not obvious when reading only the words.</p><p>Known and Unknowns Identify and label what is given and what is required, using appropriate units.</p><p>ISOLATE THE UNKNOWN</p><p>Select an Equation Identify an equation that will enable you to solve for the unknown. This first equation should contain the unknown. </p><p>Solve Symbolically Using only the symbols, solve for the unknown.</p><p>Search Systematically If one equation is not enough, then use the basic physical principles to identify other equations to solve simultaneously.</p><p>SUBSTITUTE Plug in both the numbers and the units.</p><p>EVALUATE Are the sign, magnitude, and units correct: Compare with your diagram, intuition, and knowledge. Does the answer make sense? If you like your answer, place a check mark beside it.</p>
