实验教学时初中物理的重要课型,新课程背景下我们意识到传统的灌输式教学肯定对学生的发展有滞涨作用,但是全盘放手让学生自主探究又会耗费大量的课堂时间,新课程在强调学生学习主体性地位的同时,也强调教师主导性作用的发挥.对于初中物理实验教学如何发挥教师的主导性作用呢?首先,我们要熟悉初中生的学龄特点,他们在物理学习前分析问题大多属于经验型逻辑思维,物理学习要求学生有一定的抽象逻辑思维能力,要能从现象的观察中总结出理论。学生的思维对直观的现象和直接获得的感性经验依赖度较高,“实验”无论是演示实验还是学生分组实验,都能给学生亲眼观察、亲自动手的体验,实验教学符合初中生的学习心理和认知规律.在学生观察实验和做实验的过程中,教师如何发挥主导性作用,使实验成为学生物理素 Under the background of the new curriculum, we realized that traditional indoctrination teaching certainly has a stagflation effect on the development of students. However, letting students go all-out to explore their own will consume a great deal of class time. At the same time, it also emphasizes the teacher’s leading role.As for how to play the leading role of teachers in junior high school physics experiment teaching? First of all, we must be familiar with the junior high school students’ school-age characteristics, and they analyze the problem before physics study Mostly belong to the experience of logical thinking, physics learning requires students to have a certain degree of abstract logical thinking, to be able to sum up the theory from the phenomenon of observation. Students’ thinking has a high degree of reliance on intuitionistic phenomena and directly acquired perceptual experience. Experiments show that pupils can observe with their own eyes and hands-on experiences experimentally, which is in line with the needs of junior high school students Learning psychology and cognitive law.In the process of students observation experiment and experiment, how teachers play a leading role in making the experiment a student physical element
