力学是初中物理教学中的重难点,初中生在双基学习的过程中较多地依靠自己的感性认识,理性思考往往不足,这就需要教师在教学中应用适切策略,及时加以引导,加深对概念、规律的理解,进而提升教学的有效性,本文从物理概念的理解、物理规律的应用和物理实验的拓展三个角度对此进行阐述。 Mechanics is a heavy and difficult point in junior high school physics teaching. Junior high school students rely more on their own perceptual knowledge in their learning process and their rational thinking is often inadequate. This requires teachers to apply appropriate strategies in teaching, guide them in time and deepen The concept and the law of understanding, and then enhance the effectiveness of teaching, this article from the understanding of the concept of physics, the application of the laws of physics and physical experiments to expand the three angles of this elaboration.
