本研究在计算机程序设计领域考察了反思性自我解释对概念理解和问题解决的影响。在完成多项选择测试后，33名学生被要求反思并解释为什么他们的答案是正确的或不正确的。根据反思自我解释的程度和先验知识，分组进行事后分析。结果表明，积极参与反思性自我解释过程的学生在最少指导下的问题解决任务中表现更好。先验知识对于有效思考至关重要，尤其是对原则的回顾。尽管缺乏先验知识的学生倾向于坚持错误的心理模型，但自我解释活动帮助他们修复了模型。讨论了反思性自我解释与先验知识的关系。
In this study, the effects of reflective self-explanations on conceptual understanding and problem solving are investigated in a domain of computer programming. After completing a multiple-choice test, 33 students were asked to reflect on and explain why their answers were correct or incorrect. Groups were divided for post hoc analysis based on the degree of reflective self-explanation and prior knowledge. Results indicated that students who actively engaged in the reflective self-explanation process performed better in problem solving tasks with minimal guidance. Prior knowledge was critical for effective reflection, especially recalling principles. Although low prior knowledge students tended to persist with their faulty mental models, self-explanation activities helped them to repair their models. The relationship between reflective self-explanation and prior knowledge is discussed.
