大型物理导论课程中学生对力学问题的分类：与Chi，Feltovich和Glaser研究的比较
Categorization of Mechanics Problems by Students in Large Introductory Physics Courses: A Comparison with the Chi, Feltovich, and Glaser Study
摘要：
受Chi，Feltovich和Glaser [1]经典研究的启发，我们要求三个入门物理课的入门物理学生根据解决方案的相似性对力学问题进行分类。为了评估问题情境对学生分类能力的影响，本研究设计了两组分类问题。学生们被要求分类的一组问题中的一些问题包括Chi等人先前研究中的问题。我们的研究结果与Chi等人的研究结果相反，这表明在入门学生中专业知识的分布要广泛得多。
英文摘要：
With inspiration from the classic study by Chi, Feltovich, and Glaser [1], we asked introductory physics students in three introductory physics classes to categorize mechanics problems based upon similarity of solutions. To evaluate the effect of problem context on students' ability to categorize, two sets of problems were developed for categorization. Some problems in one of the problem sets that students were asked to categorize included those available from the prior study by Chi et al. Our findings, which contrast from those of Chi et al., suggest that there is a much wider distribution of expertise among introductory students.
