根据自己的教学实践,我对开放性题目的类型和功能作了初步探索,总结了以下几种类型和不同的训练功能.一、“散射型”开放题“散射型”开放性题目(图1),属于正向开放题.这是一种最常见的开放性习题,要求从少量的已知条件出发,探索可能求解出来的多个物理量并计算.如果学生对相关量及相关公式没有透彻的理解,则非常容易出现漏解. According to my own teaching practice, I made a preliminary exploration of the types and functions of open topics, summed up the following types and different training functions. First, “scattering” open questions“scattering” openness The title (Figure 1) is a positive open question. This is one of the most common open questions and requires starting from a small number of known conditions to explore and calculate multiple physical quantities that may be solved. If students are related to related quantities and related Without a thorough understanding of the formula, it is very easy to leak.
