初中的生物课,一直以来学生都不太重视,即使已经被纳入了统考,但是在学生的心目中,仍然被摆在“副科”的位置。如果要求他们课后花时间去复习基本上是不太可能的。因此,提高生物课堂的教学效率就显得尤为重要。如何让学生在有限的45分钟内,尽可能地掌握好重点知识点呢?这是需要我们每一位生物教师研究和考虑的。笔者在平时的教学中,注重从以下几个方面入手,从而极大地优化了课堂教学的效果,在此谈点浅见,与同行共讨。 Junior biology class, students have not paid much attention, even though it has been included in the exam, but in the minds of students, is still placed in the “deputy section ” position. If you ask them to spend time after class to review is basically impossible. Therefore, it is very important to improve the teaching efficiency of biology class. How to make students grasp the key points as much as possible in a limited 45 minutes? This is the need of each of our biological teachers to study and consider. The author in the usual teaching, focusing on the following aspects, thus greatly optimizing the effectiveness of classroom teaching, talkative in this humble opinion, discuss with colleagues.
