高中生物实验教学是对学生进行素质教育的大舞台,教师应引起足够的重视,那么在新课程背景下,如何改变传统的实验教学,使学生在实验课上有所收获,本人结合自己的教学实践,对高中生物实验教学进行探讨。一、实验准备要有“效”度生物实验之前,教师必须要做好充分有效的准备,包括学生基础知识的准备和实验材料的准备。基础知识是顺利进行实验的必要条件,但是复习知识时又不能像课堂一样面面俱到,而是要在几分钟内平中见奇、快速切入与本实验有关的知识,直接触及实验的实际需要。实验的器材准备也必须有效,首先要让学生知道该实验所要的器材,并且还
In the background of the new curriculum, how to change the traditional experimental teaching so that the students can gain some experience in the experimental class, I will combine my own teaching Practice, discussion of high school biology experiment teaching. First, the experimental preparation To have “effective” degree of biological experiments, teachers must be fully and effectively prepared, including the preparation of students’ basic knowledge and preparation of experimental materials. The basic knowledge is a necessary condition for the smooth running of the experiment. However, when reviewing the knowledge, it can not be as comprehensive as in the classroom. Instead, it is necessary to see the knowledge within a few minutes and rapidly cut into the knowledge related to the experiment, which directly touches on the actual needs of the experiment. Experimental equipment preparation must also be effective, first let the students know the equipment required for the experiment, and also
