摘要
在国内外关于问题解决中表征和策略研究的基础上 ,本研究提出了高中学生解决计算类化学问题的五个表征层次和四种解决策略 ,并用出声思维法对 15位典型被试学生进行了详尽的个案分析。研究结果表明 :高中学生在解决计算类化学问题时的表征程度 (包括表征时间的长短和表征正确率的高低 )决定了其问题解决策略的选取 ,表征程度高的学生倾向于选择相对优化的策略。
The five representation hierarchies and four kinds of strategy are presented for stoichiometric chemical problem solving on the basis of other's relative researches on this domain in several decades, and at the same time 15 typical students are studied as cases in detail with Think-Aloud method The results suggest that the strategy chosen depends on the degree of representation (including representation time and accurate representation rate) and students with deep representation are inclined to choose superior strategies when students are solving stoichiometric chemical problems
