题目分类方法研究是物理教育研究领域中的一项重要内容,可以揭示学生对于物理概念的建立过程.本文运用物理问题表征分类的研究方法,通过对高中3个年级的学生进行测试,总结了高中学生对曲线运动类题目的分类特点,分析了不同年级学生的分类差异,并研究了图示对于学生分类方式的影响.结果显示,高一学生中有较高比例会按照所求解的未知量等表面特征对问题进行分类,且容易受到示意图的干扰;高三学生则较多按照题目涉及的核心概念与原理对题目进行分类,且在分类时能够较好地排除题目中的干扰因素.
Research on subiect classification method is an important content m the tlela oi physical education research, which can reveal the establishing process of the students in physi- cal concept. In this paper, through the testing to the high school students of three different grades, we use the research methods of the physical problems representation classification to summarizes the classification characteristics of the high school students to the curve movement problems. Differentiation of classification between different grade students are analyzed, and the influence of graphic to the students" classification methods are discussed. Results show that a higher proportion of the students in grade one will classify the problems according to the surface features of the to be solved unknown quantities, and they are easily disturbed by the schematic diagram. Contrarily, most of the students in grade three classify the problems ac- cording to the core concept and principle involved in the subject, and they can do better in eliminating the interference factors of the subject.
