自主 创新 改变——浅议初中生物演示实验的“新”教法

Autonomy,innovation and change--on the new teaching method of biology demonstration experiment in junior middle school

演示实验是生物教学不可或缺的一环。通过演示实验,能将教材中抽象、复杂的生物知识以直观、可视的形式表现出来,诱发学生的探究学习热情,在观察实验与思考实验过程中实际解决问题。虽然演示实验的重要性不言而喻,但是生物课堂上开展演示实验的效果并不理想,陷入“老师不愿做,学生不愿看”的尴尬层面,演示实验应付了事。基于新课标的倡导,演示实验教学改革再次被提上日程,本文以“自主”“创新”“改变”为关键词,探讨生物演示实验的“新”教法。

demonstration experiment is an indispensable part of biology teaching.Through the demonstration experiment,the abstract and complicated biological knowledge in the textbook can be displayed intuitively and visually,which can induce students'enthusiasm for inquiry learning and solve practical problems in the process of observation experiment and thinking experiment.Although the importance of demonstration experiment is self-evident,the effect of demonstration experiment in biology class is not ideal,falling into the embarrassing level of"teachers do not want to do,students do not want to see",and the demonstration experiment has handled the matter.Based on the advocacy of the new curriculum,the reform of demonstration experiment teaching has been put on the agenda again.This paper discusses the new teaching method of biology demonstration experiment with the key words of"independence","innovation"and"change".
