高中物理学业成绩两极分化是一种常见的现象.针对高中生物理学业成绩两极分化现象描述性统计分析研究发现,一是高中生物理学业成绩两极分化存在过度分化现象;二是两极分化现象发展变化过程中存在增长期、稳定期等关键期;三是物理知识水平整体较弱的班级两极分化现象更为显著.抓住不同时期存在的问题,提出了开展班内互助小组、查缺补漏班、教师关注课本后面的“科学漫步”“STS”等环节的有效教学策略.
High school physics academic performance polarization is a common phenomenon. According to descriptive statistical analysis of high school students’ physics academic performance, the polarization phenomenon of physics academic performance is excessively differentiated; the second is the development of polarization. In the process, there are key periods such as the growth period and the stabilization period. Third, the polarization of classes with weak overall physics knowledge is even more pronounced. Grasping the problems existing in different periods, it proposes the development of in-class mutual aid groups and the identification of missing classes. Teachers pay attention to effective teaching strategies such as “Scientific Walking” and “STS” at the back of the textbook.
