中学物理教学的目的,一方面是使学生掌握物理概念和规律,另一方面是逐步使他们具备独立获得知识的能力,诸如自学能力、分析、概括、抽象、推理、想象等思维能力以及研究物理问题的科学方法等。因此,教师的主导作用不仅应表现为上好一节课的教学技巧,还应有课堂教学设计的总体策略,以利于知识的传授和能力的培养。本文结合教学实践,对此做初步探讨。一、鼓励和引导学生自觉培养自学能力的策略实践证明,学生自学能力的提高,不仅是培养能力的需要,也有助于物理知识的掌握。前不久,有一位高二学生对课堂上反复强调的“电场强度的方向就是放在该点的正电荷受力方向,而负电荷在电 The purpose of middle school physics teaching is to enable students to master the concepts and laws of physics. On the other hand, they gradually enable them to acquire the ability to acquire knowledge independently, such as self-learning ability, analysis, generalization, abstraction, reasoning, imagination, and other thinking ability and research physics. Scientific methods of the problem, etc. Therefore, the teacher’s leading role should not only be a good one-class teaching skill, but also should have the overall strategy of classroom instruction design in order to facilitate knowledge transfer and ability development. This article combines teaching practice, to do a preliminary discussion. First, encourage and guide students to consciously develop their own strategies for self-study ability Practice has proved that the improvement of students’ self-learning ability is not only the need to cultivate abilities, but also helps to grasp the physical knowledge. Not long ago, a senior high school student repeatedly emphasized in the classroom that “the direction of the electric field strength is the direction of the positive charge on this point, and the negative charge is on the electricity.
