最近本人聆听了同备课组老师的一节氧化还原反应的公开课,氧化还原反应属于基本概念理论课,属于高中化学的一个难点,由于一些概念比较的抽象,所以在讲述时比较枯燥乏味,学生的兴趣不高,掌握的较差.但由于该老师做了精心的准备,所以整节课给人感觉条理清楚,讲解也很到位,在授课的过程中有小组合作,有自主阅读,有跟踪练习,表面上看学生都积极参与到学习过程中.这节课是按照人教版的编排来设计,整节课分为如下几个环节:(1)新课引入,回顾四种基本反应类
Recently, I have listened to an open class of redox reactions with the teacher of the preparation group. The redox reaction is a basic concept theory class and it is a difficult point in high school chemistry. Due to the abstract comparison of some concepts, it is relatively boring to talk about students. The interest is not high, but the mastery is poor. However, because the teacher has made meticulous preparations, the entire lesson gives a clear sense of clarity and explanation. It is also in place. In the course of teaching, there is group cooperation, independent reading, and tracking. Exercises, on the surface, students are actively involved in the learning process. This class is designed according to the layout of the PEP. The entire class is divided into the following sections: (1) Introducing the new class and reviewing the four basic types of response
