近年来,我运用“练、看、读、议、讲”的教学形式,对“指导发现法”进行了初步探索,即从加强生物实验,培养学生的动手能力和观察能力入手,以实验为基础组织教材进行教学活动,突出教师的主导作用和学生的主体地位,以学生的自学为主.现以“鲫鱼”一节的教学为例,谈谈具体做法和体会. In recent years, I have made a tentative exploration of the “Guidance Discovery Law” by using the teaching forms of “practice, reading, reading, speaking and speaking”, starting from strengthening biological experiments and training students’ abilities of starting and observing, Basic teaching materials for teaching activities, highlighting the dominant role of teachers and the dominant position of students, mainly to students’ self-learning. Now “crucian carp” section of teaching as an example, talk about the specific practices and experiences.
