科学取向教学论对教学实践的重要贡献,就是它认识了不同类型的学习与教学策略、教学评价之间的必然联系。根据该教学论可将现有中学化学课堂教学分为如下几类课型:元素化合物课、概念课、原理课、基本技能课、高级技能课、复习课等。其中,概念课的教学具有三个显性的教学任务:1.知道概念是什么(名称、定义、属性和例证分析);2.运用概念去办事(分类、属性的运用);3.辨明新概念与有关概念的关系,形成概念 The important contribution of science-oriented teaching theory to teaching practice is that it recognizes the inevitable connection between different types of learning and teaching strategies and teaching evaluation. According to the teaching theory, the existing middle school chemistry classroom teaching can be divided into the following types of courses: element compound class, concept class, principle class, basic skill class, advanced skill class, review class and so on. Among them, the concept of teaching has three dominant teaching tasks: 1. To know what the concept (name, definition, attributes and examples of analysis); 2. To use the concept to work (classification, the use of attributes); 3. Identify new Relationship between concepts and related concepts, forming concepts
