生物课堂练习对于知识的内化,学习的矫正和教学的调节都有重要作用,因此,在教学过程中,演练一定量的课堂练习是十分必要的。然而,编选什么样内容的练习,采用什么样方式进行演练,以及选择什么佯的时机进行演练才能获得最佳效果等问题,值得探索研究。几年来,我们在高中生物教学过程中,做了一些尝试,现将心得体会总结如下。 Biology classroom exercises play an important role in the internalization of knowledge, the correction of learning, and the adjustment of teaching. Therefore, in the teaching process, it is necessary to exercise a certain amount of classroom exercises. However, it is worth investigating and researching what sorts of exercises are compiled, what kind of methods are used for drills, and what timings are chosen for conducting drills to obtain the best results. Over the past few years, we have made some attempts in the process of biology teaching in high schools. We will now summarize our experience and experience as follows.
