物理作为实践性较强的学科,不仅对于知识的掌握和运用能力有较高的要求,同时,对于学生动手能力和实践能力有较高的要求。因此,应该重视演示实验的作用,充分发挥演示实验的重要性,本文重点探讨演示实验如何有效提升初中物理的教学质量。1.初中物理教学中演示实验的必要性1.1初中生的自身特点要求课堂上采用演示实验初中生的年龄阶段决定了他们的逻辑思维能力欠缺,直观观察能力较强。初中物理中出现了较多的理论性较强的知识,导 Physics as a practical discipline, not only for the mastery of knowledge and ability to use a higher demand, at the same time, the students practical ability and practical ability have higher requirements. Therefore, we should attach importance to the role of demonstration experiments, give full play to the importance of demonstration experiments, this paper focuses on how demonstration experiments can effectively improve the quality of junior high school physics teaching. 1. Necessity of demonstrating experiment in junior high school physics teaching 1.1 The characteristics of junior high school students require demonstration experiment in classroom Junior high school students’ age determines their lack of logical thinking ability and strong visual observation ability. Junior high school physics appeared more theoretical knowledge, guidance
