在新课程标准的要求下,高中的化学课堂在教学上势必要寻找一种有效——高效的模式,使学生的负担真正得到减轻。本文围绕高中的化学课堂在教学上关于导入这一环节展开探讨,阐明了化学课堂在导入环节存在的问题,讲解了课堂在导入时的策略,为课堂导入提供了一些的方法并做了举例说明。希望能为高中化学在课堂导入这一环节有些许帮助。 Under the requirements of the new curriculum standards, the chemistry class in senior middle school is bound to find an effective and efficient model in teaching, so that the burden on students can be reduced. This article explores the introduction of this link in the teaching of chemistry classes in senior high schools, clarifying the problems in the introduction of chemistry classes, explaining the strategies of classroom introduction, providing some methods for classroom introduction and giving examples. . I hope to help the high school chemistry in the classroom to help this section.
