通过两类试题对初二学生物理问题解决的四种表征进行研究,得出结论:①差生的朴素表征错误率最高,且更倾向于利用生活经验对问题解答;②中等生的物理、数学表征错误率最高,其对物理概念以主观理解为主,数学计算能力亦差于优生;③优生在文字表征层次错误率最低,其主要错误集中在数学表征。对学生错误深层次的分析,希望能进一步提高教师教学的针对性,提高教学效率。
Through two kinds of test questions on the junior middle school students to solve the four kinds of characterization of the study to draw conclusions: ① poor student simple characterization error rate is highest, and more inclined to use life experience to answer questions; ② secondary students physical and mathematical characterization The error rate is the highest, and its subjective understanding of the concept of the main physics, math computing ability is also inferior to that of eugenics; ③ eugenics in the text characterization level of the lowest error rate, the main error focused on the mathematical characterization. In-depth analysis of the mistakes of students, hoping to further improve the teaching of teachers targeted to improve teaching efficiency.
