章节摘录

插图:A strategy is a goal-directed sequence of mental operations. Selecting a strategy is themost important and also the most difficult step in the problem-solving process.Although there may be several strategies that will lead to the solution of a problem,the skilled problem solver uses the most efficient strategy. The choice of the mostefficient strategy is based on knowledge and experience as well as a careful applica-tion of the clarify and explore steps of the problem-solving method. Some problemsmay require the use of a combination of strategies. The following search methods may help you to select a strategy. They do not rep-resent all of the possible ways in which this can be done. Other methods of strategyselection are related to specific content areas.  a. Trial-and-error search: Such a search either doesn't have or doesn't use informa-  tion that indicates that one path is more likely to lead to the goal than any other  path.  Trial-and-error search comes in two forms, blind and systematic. In blind search,  the searchers pick paths to explore blindly, without considering whether they  have already explored these paths. A preferable method is systematic search, in  which the searchers keep track of the paths they have already explored and do  not duplicate them. Because this method avoids multiple searches, systematic  search is usually twice as efficient as blind search.  b. Reduction method: This involves breaking the problem into a sequence of  smaller parts by setting up subgoals. Subgoals make problem solving easier  becaue they reduce the amount of search required to find the solution.  You can set up subgoals by working part way into a problem and then analyz-  ing the partial goal to be achieved. In doing this, you can drop the problem  restrictions that do not apply to the subgoal. By adding up all the subgoals, you  can solve the "abstracted" problem.  c. Working backward: When you have trouble solving a problem head-on, it is  often useful to try to work backward. Working backward involves a simple  change in representation or point of view. Your new starting point is the origi-  nal goal. Working backward can be helpful because problems are often easier to  solve in one direction than another.

  •     OK,250196348,还不错
  •     内容很完全,但有些繁复。
    而且还有超纲,个人认为一般。
    不适合基础弱的人读。
  •     部分翻译 单词 还有 结构图 有错误 可能是印刷问题
  •     还行,封面有点划痕
  •     印刷不错,但整本书有被很大程度地折过,后来又被摊平了,看得出来
  •     比较难.有很多的点是高中不讲不学的.但看2010年6月的情况来看做Barron还是靠谱的.多学一点没坏处.
