Select a Strategy
There are several possible strategies that may be used to solve a problem:
1. Algorithms:Rule based strategy that is guaranteed to work (i.e. solving an equation). It is not always possible to use this strategy because a rule may not exist for your situation, or you may not have the knowledge to apply the rule. The video to the right explains how algorithms are increasingly used to solve problems, and it may help expand your thinking and creative ideas in this area. |

2. Heuristics:A mental shortcut or rule of thumb that allows you to make decisions quickly based on prior knowledge and experiences. Remember that just because something worked once does not mean that it will work again, or that it was the best solution the first time. The video to the left defines several specific types of heuristics and how we use them in daily life. |
3. Trial and Error: Repeated attempts to solve a problem through various methods by the process of elimination. Trial and error least efficient option because it involves no strategic planning, however, it may be the only option when faced with an unexpected and unfamiliar problem. The video to the right provides a humorous example of why trial and error is usually not the best method. |

4. Means-Ends Analysis: For this strategy you must (1) set a goal, (2) break down the problem into smaller problems, (3) evaluate your success at each step before moving forward. The video to the left discusses solving a problem by working backwards. |
Expert problem solvers tend to use some form of means-ends strategy to break down the problem into smaller parts and solve sequentially. Good problem solvers also tend to be good planners who look further ahead to coordinate the entire problem solving sequence.
