ACTIVITIES
- introduce variables for unknown; write equations, relations
- re-read the problem as if you were editing it: analyze givens, make unstated assumptions explicit, clarify goals
- hit-miss attempts; try special cases
- identify concept behind problem, type of problem, section of book from which taken
- begin with answer if given, or approximate an answer, and try to figure out how it was obtained
- draw a figure and label givens, close your eyes to form a mental picture and then imagine what the experiment would look like if you set up the equipment
- recall or use the text or notes to find a similar problem, method, result, useful theorem technique
- think of every formula or definition related to the concept or terms
- try cases searching for a pattern
- work with classmate, friend
- after trying all other tactics, ask for hints or explanations
- break problem into simpler problems; do only part of problem
- if making no progress after 30 minutes, stop working on problem, sleep on it, or leave it for a few hours
- compare units in answer you want to compute with units in given information, look for conversion factors involving these units
- check and verify your work; is solution reasonable
- assume you are going to ask the instructor for help: what would you ask? Identify what you need to know to solve the problem.
