在物理的课堂教学中,经常会有一些概念、规律、情景,学生在理解起来有一点的难度,但若能利用一些巧妙的小实验,不仅能激发学生学习物理的兴趣,巩固学生对物理知识的掌握,还能提高学生的实验操作技能,培养学生的科学创新能力。就在课堂教学中用小实验来研究电压与电量的关系。 In physical classroom teaching, there are often some concepts, rules and scenarios. Students can find it a little harder to understand. However, if some clever experiments are used, they can not only stimulate students’ interest in physics but also consolidate their knowledge of physics. Mastery, but also improve students ’experimental skills, develop students’ ability of scientific innovation. In the classroom teaching with small experiments to study the relationship between voltage and power.
