在课堂教学中,结合教材内容,选择适当的实验来进行各种不同的谈话课,使教师的活动与学生的活动很好地结合起来,使理论与实际紧密地联系起来,对引导学生积极思维,以加深与巩固其所得知识,有着很显著的效果。现在举出我在运用这个方法讲授强电解质与弱电解质这一课的过程,说明我个人的一些体会。根据课时计划,这一课的主要目的有三:①使学生在了解电解质和非电解质的基础上进一步认识强电解质和弱电解质;②使学生了解电解质的强弱决定于离解的强弱,而离解的强弱,又与电解质本身及其浓度有
In the classroom teaching, combining the contents of the teaching materials, choosing the appropriate experiment to carry out a variety of conversation classes, so that the teacher’s activities and student activities are well integrated, so that theory and practice are closely linked to guide students to actively think , In order to deepen and consolidate the knowledge acquired, has a very significant effect. Now I cite the process of using this method to teach strong electrolytes and weak electrolytes, illustrating some of my personal experiences. According to the lesson plan, the main purpose of this lesson is to: (1) enable students to further understand strong electrolytes and weak electrolytes on the basis of understanding electrolytes and non-electrolytes; (2) enable students to understand the strength of electrolytes depending on the strength of dissociation and dissociation Strength, but also with the electrolyte itself and its concentration
