摘　　要：“闭合电路欧姆定律”是高中物理电学内容的重要组成部分.然而,学生在学习过程中,认知负荷往往较高,学习效果不尽人意.如何在教学中降低学生的认知负荷,促进学科核心素养目标的实现,无疑又是一个新的课题.因此,基于认知负荷理论,对“闭合电路欧姆定律”这节内容进行了分析,并在该理论指导下进行教学设计,旨在减少学生的外在认知负荷,增加关联认知负荷,以期为新时期的高中物理课堂教学提供一些有益的参考."Ohm’s Law of Closed Circuit" is an important part of electricity content of high school physics.However, in the process of learning, the cognitive load of students is often high, and the learning effect is not satisfactory.How to reduce students’ cognitive load in teaching and promote the realization of the subject’s core literacy goal is undoubtedly a new topic.Therefore, based on cognitive load theory, this paper analyzes the section of "Ohm’s Law of closed Circuit", and under the guidance of this theory, teaching design is designed to reduce students’ extraneous cognitive load and increase their germane cognitive load, in order to provide some useful reference for the new period of high school physics classroom teaching.
