生物新教材中安排了很多学生课堂实验,这充分体现了生物教学大纲指出的“生物学是一门实验科学,观察和实验是学习生物科学的基本方法”。努力创造条件,结合学生心理、生理特点,克服困难,完成大纲、教材规定的课堂实验教学任务,培养学生的能力,发展智力,提高学生素质,提高生物教学质量,是生物教师的责任。但是,如何让学生对生物实验教学更感兴趣,如何提高学生的实验素质呢?笔者是通过预习指导,现场操作示范及实验操作考查等方法,强化了生物实验课教学。中学生物实验包括演示实验、学生分组实验和课外小实验,它们都是很好的素材,只要教师做实施素质教育的有心人,对它们合理的加以应用,一定会在教学中收到良好的效果。
Biological biology teaching materials arranged a lot of students in classroom experiments, which fully reflects the biological syllabus pointed out that “biology is an experimental science, observation and experiment is the basic method of learning biology.” Efforts to create conditions, combined with the psychological and physiological characteristics of students, overcome difficulties, the completion of the outline, teaching materials required classroom experimental teaching tasks, develop students’ ability to develop intelligence, improve the quality of students and improve the quality of biological teaching is the biological teacher’s responsibility. However, how to make students more interested in biological experimental teaching, how to improve students’ experimental quality? The author is through pre-instruction, on-site operation demonstration and experimental operation examination and other methods, and strengthen the biological experiment teaching. Middle school biology experiments include demonstration experiments, student group experiments and extra-curricular experiments, which are all very good materials. As long as teachers are conscientious people who implement quality education and apply them reasonably, they will surely receive good results in teaching.
