物理问题的多元表征能力直接影响着学生解决物理问题的能力。然而个体在物理问题多元表征方面存在差异,对于物理问题多元表征会有障碍。笔者结合前者的研究,以问卷调查的方式,对一千多名中学生个体问的表征差异与障碍进行了分析,得出在不同的背景因素下,个体在不同的表征方式中存在的差异与障碍,并对障碍存在的原因进行了分析,使教师能够全面的了解学生物理问题多元表征的差异和障碍,从而有利于培养学生对物理问题多元表征的能力。
The multiple characterization of physical problems directly affects students’ ability to solve physical problems. However, individual differences exist in the multi-characterization of physical problems and obstacles to the multi-characterization of physical problems. Based on the former research and the method of questionnaire, the author analyzes the difference and obstacle of the representation of more than a thousand middle school students and finds out the difference and obstacle of the individual in different representation under different background factors , And analyzes the reasons for the existence of obstacles so that teachers can comprehensively understand the differences and obstacles in the multi-characterization of students’ physical problems so as to help students develop their ability to represent the multiple problems of physical problems.
