创新能力是当今时代科技、经济发展对人才素质提出的必然要求,物理作为一门以实验为基础的学科,在培养学生创新能力方面具有其他学科不可替代的重要作用[1]。本文以探究黑箱内的电学元件为实验基础,通过对多用电表使用的介绍,引导学生利用多用电表自主探究进而了解黑箱的内部结构,使学生的动手能力和创新能力得到很好地培养。 Innovative ability is an inevitable requirement for the quality of human resources in science and technology and economic development in current times. As an experiment-based discipline, physics plays an irreplaceable role in cultivating students’ innovative abilities. This paper explores the electrical components in the black box as the experimental basis, through the introduction of the multi-use meter, to guide students to use multi-meter to explore and understand the internal structure of the black box, so that students’ practical ability and ability to innovate well.
