生物学是一门以实验为基础的自然科学。许多生物现象只有通过实验才能得到解释,各种生物体的结构必须通过实验才能观察清楚,生物学的理论也是人们通过实验总结出来的。所以实验教学在生物教学中占有非常重要的地位。由于历史的原因,我国的生物实验教学起步较晚,以致重知识、轻实验,重理论、轻实践,学生的“高分低能”现象至今仍相当严重。随着教育的改革,注重了理论和实践相结合的原则,教材内容突出了实验内容多。实验形式多,实验要 Biology is an experiment-based natural science. Many biological phenomena can only be explained through experiments. The structure of various organisms must be clearly observed through experiments. The biological theory is also summarized by experiments. Therefore, experimental teaching occupies a very important position in biology teaching. Due to historical reasons, the teaching of biological experiments in our country started relatively late, so that the phenomena of “knowledge, light experiment, heavy theory and light practice” and “high and low energy” of students are still quite serious. With the reform of education, pay attention to the principle of combining theory with practice, teaching content highlights the experimental content. More experimental form, experiment to
