笔者经过多年的物理教学实践和研究,认真抓住学生思维灵活性的培养,有效地提高物理教学效果.在电学教学中采取以下几方面培养学生思维的灵活性:一、灵活识别电路图是学好电学的基础学生能正确判断电路的通、断和电路的连结方法,才能对问题作出正确判断和选择.例:图1电压表示数分别为 U_1、U_2、U_3,电流表示数为 I_1和 I_2,则下列关
After many years of physics teaching practice and research, the author has carefully grasped the cultivation of students’ thinking flexibility and effectively improved the effect of physics teaching. The following aspects were adopted in the teaching of electricity to cultivate the flexibility of students’ thinking: 1. Flexible recognition of circuit diagram is to learn electricity well. The basic students can correctly judge the connection, disconnection and circuit connection of the circuit in order to correctly judge and select the problem. For example, the voltage representation numbers in Figure 1 are U_1, U_2, U_3 respectively, and the current representation numbers are I_1 and I_2. Following
