自2020年初，新型冠状病毒肺炎席卷全球,我国各学段的学校均开启线上教学模式。经过一段时间的适应，线上教学工作进入正轨。同时，不同学校也在根据所在地疫情情况、自身实际情况等不断调整线上教学方案。线上教学成为近几年来十分普遍的一种教学方式。而线上教学存在其利弊，一定程度上对教学效果产生了影响。本文通过对一线教师进行访谈，得到影响线上教学效果的因素，并结合影响因素与物理学科核心素养进行问卷调查。对调查结果进行分析，对物理学科在线上教学过程中出现的问题进行讨论与研究，提出相应的意见。

Since the beginning of 2020, novel coronavirus pneumonia has swept the world, and all schools in China have started online teaching. After a period of adaptation, online teaching work is on the right track. At the same time, different schools are constantly adjusting their online teaching programs based on the local epidemic situation and their actual situation. Online teaching has become a very common teaching mode in recent years. Online teaching has its advantages and disadvantages, which to some extent has an impact on the teaching effect. Through interviews with front-line teachers, this article obtains the factors that affect the effectiveness of online teaching, and conducts a questionnaire survey combining the influencing factors and core literacy in physics. Based on the analysis of the survey results, this article discusses and studies the problems encountered in the online teaching of physics, and puts forward corresponding suggestions.
