初中物理教学中,有一些问题由教师基于知识的逻辑顺序设计的,有一些问题是从学生学习的角度诞生的.后一类问题由于来源于学生的学习过程,因而更具有原始的味道,我们称之为原始问题.这类问题由于来自于学生的生活或思维,因而更容易激发学生的思考.如果教学中能够更多地发现、设计并利用这些原始问题,可以让物理的学习更有效.本文试以初中物理中的欧姆定律教学为例,谈谈笔者对原始问题的设计与应用. Some problems in junior high school physics teaching are designed by teachers based on the logical order of knowledge, and some problems arise from the perspective of students’ learning.The latter kind of questions have a more original taste because of their learning process, Call them original problems, which are more likely to stimulate students ’thinking because they come from the students’ life or thinking.If teaching can find more, design and use these original problems, it can make physics study more effective. This article attempts to junior high physics teaching Ohm’s law, for example, to talk about the original design and application of the author.
