当今,高效课堂成为新课改教学追求的目标。科学课注重以探究为核心,实验教学是课堂中最难以把握的,要想让学生做好实验,从实验中找到证据,得出科学的结论,实验器材的精心准备、实验方法的适当指导,实验中小组的合作、数据的整理分析等诸多环节都要注重细节。一、精心准备实验器材是完成实验的前提1.教师准备器材时要检查器材是否完好。器材不完好,学生操作就有困难。如,我听过一位刚教科学不久的老师上了一节《导体和绝缘体》,要求学生检验哪 Today, efficient classrooms become the goal of the new curriculum reform. Science class focuses on inquiry as the core, experimental teaching is the most difficult to grasp in the classroom, in order to allow students to experiment, find evidence from the experiment, draw scientific conclusions, elaborate preparation of experimental equipment, experimental methods, appropriate guidance, Experimental group cooperation, data analysis and many other aspects must pay attention to detail. First, careful preparation of experimental equipment is the prerequisite to complete the experiment 1. Teachers to check equipment when equipment is intact. Equipment is not good, students have difficulty operating. For example, I have heard a teacher who is teaching science soon to have a “conductor and insulator” asking students to test
