随着我国基础教育改革的深入发展,中学化学实验教学的改革也在逐步进行。就目前发展情况而言,中学化学实验教学改革的动向主要有三种趋势。一、分组实验向“微型化”方向发展分组实验是学生实验的主要方式。它是在单元教材学习之后,为了复习、巩固和验证课堂上所学的化学知识,并系统培养学生的实验技能和独立工作能力而进行的一种课堂实验教学形式。这种教学形式,过去由于实验条件、实验经费等诸多方面的问题,有些学校常常将实验室进行的实验改为黑板上讲实验,失去了实验本身的意义。为了解决这个问题,有人根据美国学者在大学进行微 With the deepening of the reform of basic education in our country, the reform of chemistry experiment teaching in middle schools is also proceeding gradually. In terms of current development, there are mainly three trends in the reform of chemistry experiment teaching in middle schools. First, the grouping experiment to “miniaturization ” direction The development of grouping experiment is the main way for students to experiment. It is a kind of classroom experimental teaching form after the learning of unit textbooks, in order to review, consolidate and verify the chemistry knowledge learned in the classroom, and systematically develop students’ experimental skills and independent working ability. In the past, due to various experimental conditions and experimental funding, some teaching methods often used experiments in laboratories instead of experiments on a blackboard, losing the meaning of the experiment itself. In order to solve this problem, some people conducted micro-studies in universities based on American scholars
