Developing Problem-Solving Skills in Chemical Equilibrium--A Constructive Model.
The purpose of this study is to analyze the perceived thought processes of several students as they learn, and then attempt to solve problems about chemical equilibrium. Four tenth grade students in Taipei, Taiwan, were audiotaped as they individually attempted to solve problems. The problems were such that they required more than mere recall or algorithmic learning and yet simple enough to give the learners a reasonable chance of success. It was found that successful problem solvers generated coherent and meaningful explanations, while unsuccessful problem solvers' explanations for the examples tended to show their inconsistency of understanding. As for problem-solving tasks, successful students were characterized by giving better reasoning, use of relevant principles and concepts to justify their answers, frequent checks of the consistency of answers, and better quality of procedural knowledge. The results suggest the textbook used lacked sufficient information for all students to be able to develop knowledge and skills to solve the problems. (PR)
