要提高学生对抽象物理概念和规律的理解,教师可以通过利用低成本自制教具来演示教学内容,提高教学的有效性,通过自制低成本教具来培养学生对物理实验的兴趣,增强学生的动手实践能力。因为低成本自制教具取材方便、贴近生活、操作简便,而且取得的实验现象比较明显,有利于学生加深对物理规律的掌握,因此,教师在教学中应多加以运用。 To enhance students ’understanding of the concepts and laws of abstract physics, teachers can demonstrate their teaching content by using low-cost self-made teaching aids to improve the effectiveness of teaching. By using self-made low-cost teaching aids to cultivate students’ interest in physics experiments and enhance student hands-on practice ability. Because low-cost self-made teaching aids easy access, close to life, easy to operate, and the experimental phenomenon is more obvious, is conducive to students to deepen the grasp of the laws of physics, therefore, teachers should be used more in teaching.
