活动单导学教学模式被推广已经很长时间了。活动单导学模式在新的教学环境中其实际作用有多大?其在课堂教学过程中是否还存在这样那样的问题?这些都需要用实践进行必要的证明。本文笔者就以一节公开课为例分析现有化学课堂中活动单导学模式存在的几个突出问题。本节课是一堂《有机物结构的确定》复习课,全课以掌握通过分子组成确定有机物结构的方法,掌握通过物质性质推断有机物结构的方法,学会应用试题情境确定有机物结构,为课堂学习目标。
Activity-based tutorial teaching has been promoted for a long time. What is the practical effect of activity-based guided mode in the new teaching environment? Is there any such problem in the process of classroom teaching? All these need to be proven by practice. In this paper, the author takes an open class as an example to analyze the salient problems existing in the activity guided mode in the existing chemistry class. This lesson is a review course of “Confirmation of Structure of Organic Matter”. It focuses on mastering the method of determining the structure of organic matter through molecular composition, grasping the method of inferring the structure of organic matter by means of material properties, and learning to determine the structure of organic matter by using the test questions.
