Problem |
an obstacle between a present state and a goal state and it is not immediately clear how to get around the obstacle |
|
Well-defined problem |
a problem whose goals, starting information, and steps are explicitly stated |
|
ill-defined problem |
a problem that does not have a goal, starting information, or step explicitly stated |
|
problem solving |
transforming starting information into a goal state, using a specified means of solution |
|
domain-specific problem solving |
problem solving strategies that only work for certain types of problems |
|
thinking |
transforming or manipulating information that may be focused or unfocused |
|
generate and test technique |
generating possible solutions and testing them |
|
means end analysis |
comparing goal state with the starting point, thinking of possible ways to get to the end goal and choosing the best |
|
working backwards |
analyze last step needed to achieve the goal, then go to the next-to-last step |
|
backtracking |
make provisional assumptions about a problem's solution. keep track of when and which assumptions were made, in case you have to undo them |

reasoning by analogy |
analogy between current problem and another problem that has already been solved |

|
functional fixedness |
having difficulty seeing alternate uses for common objects |
|
experts |
people who have devoted a large amount of time learning about a field and practicing and applying that learning |

|
reasoning |

always true |
|
contradiction |
always false |
|
syllogistic reasoning |
reasoning with problems concerning relationships among categories |
|
categorical syllogism |
premises require quantifiers |
|
believability effect |
the tendency to draw or accept conclusions form premises when the content of the conclusion makes intuitive sense |
|
mental model |
specific situation represented in a person's mind that can be used to help determine the validity of syllogisms in deductive reasoning |
|
analogical reasoning |
drawing inductive inferences that specify a fourth term that projects a relationship found between the first two terms onto the third term of the analogy |
