任何自然学科都是建立在实验基础上的,生物也不例外。作为一门自然学科,生物实验是教学过程中的重点。生物实验对于培养学生学习生物的兴趣,加深理解生物学的基础知识,掌握生物实验基本技能,培养学生协作精神等,都具有重要的作用,因此在中学生物教学中必须重视实验教学。随着教育改革的推行,现行生物教材对学生实验的要求有了很大的变化:以教师讲授为主的示范性实验减少,以学生自主探究为主的实验逐渐增多。以往建立的
Any natural science is based on experimentation and biology is no exception. As a natural science, biological experiments are the focus of the teaching process. Biology experiment plays an important role in cultivating students ’interest in learning biology, deepening the understanding of the basic knowledge of biology, mastering the basic skills of biological experiment, and cultivating the students’ cooperation spirit. Therefore, we must attach importance to experimental teaching in biology teaching of middle school. With the implementation of education reform, the current biological teaching material has greatly changed the requirements of students’ experiments: the number of demonstration experiments mainly based on teachers’ teaching has decreased, and the experiment based on students’ autonomous exploration has been gradually increasing.
