生物学是一门集实验、实践与科学于一身的自然科学。在生物学教学中,实验教学不仅是必不可少的,也是至关重要的。实验可以帮助学生实现由感性认识到理性认识,由具象思维到抽象思维的飞跃。但是在广大的农村中学,生物实验教学却难以正常进行,究其原因有以下几个方面:(一)教育经费投入相对不足。在农村中学,教育经费的投入很难与城市及发达地区相比,在教育经费相对紧张的情况下,学校更不可能把钱投入到中招不考的生物实验上,有些学校的生物实验室只是摆放一些挂 Biology is a collection of experiments, practices and science in a natural science. In biology teaching, experimental teaching is not only essential but also crucial. Experiments can help students realize the leap from the concrete thinking to the abstract thinking from perceptual awareness to rational understanding. However, in the vast rural middle schools, biological experiment teaching is difficult to carry out the normal, the reason for the following aspects: (A) the relative lack of funding for education. In rural middle schools, it is very difficult for schools to devote their money to trying out biological experiments that are not involved in education, compared with cities and developed areas. In the case of relatively tight education funds, some schools’ biological laboratories Just put some hanging
