近年来,我们在部分班级采用了实验设疑法进行实验教学,有力地调动了学生学习的积极性,初步取得了较明显的效果,现简介如下: 一、指导思想: 中学化学教学的目的任务:一是传授知识,二是培养能力、开发智力,而且更重要的是后者,实验教学尤其是这样。通过生动活泼的化学现象,既可以帮助学生形成化学概念、理解和巩固化学知识,又可以培养学生观察现象、设计实验和独立操作的实验能力。所以在实验教
In recent years, we have used experiment-based methods to conduct experimental teaching in some classes, effectively mobilized students’ enthusiasm for learning, and achieved initial results. The brief introduction is as follows: I. Guiding Ideology: The purpose and task of chemistry teaching in middle school: One is to impart knowledge, the other is to cultivate ability, develop intelligence, and more importantly, the latter, especially experimental teaching. Through a lively chemical phenomenon, students can not only help form a chemical concept, understand and consolidate chemical knowledge, but also develop students’ experimental ability to observe phenomena, design experiments, and operate independently. So in experimental teaching
