在初中生物实验教学过程中,处理好教师的主导作用和学生的主体作用的关系,调动好学生动手实验的主动性和能动性,让各类实验保质保量完成,提高初中生物实验教学的实效性,达到教学目的。笔者结合多年来生物教学的经验,谈谈自己的几点体会。一、规范演示实验,激发学生学习兴趣在讲解《练习使用显微镜》一课时,用现代教学手段,播放当代生物学家用显微镜认真观察生物细胞的实验片段,然后说:"同学们,你们现在想不想像生物学家那样用显微
In the junior high school biology experiment teaching process, the relation between the leading role of the teacher and the main role of the student is handled, the initiative and initiative of the student’s hands-on experiment are mobilized, the quality and quantity of various experiments are completed, and the biological experiment teaching of the junior middle school is improved. Actual effectiveness to achieve teaching objectives. The author combines many years of experience in biology teaching to talk about his own experiences. First, standardize the demonstration experiment to stimulate students’ interest in learning In explaining the lesson “Practicing the Use of Microscopes”, use modern teaching methods to play contemporary biological home microscopes to observe the experimental fragments of biological cells, and then say: ” Students, you now think I don’t want to use microscopes like biologists do
