一、实验的假设(一)实验假设的提出初中物理的识图、作图是贯穿在力、光、电、磁各部分教学中的重要教学内容和基本学习方法,也是学生要掌握的基本技能之一.重视和加强初中物理的识图、作图教学,不仅是培养学生识图、作图能力的需要和途径,而且对于密切物理教学与生产、生活实际的联系,对于学生通过形象生动的感性内容理解知识,对于培养学生图形表述能力以及观察、实验能力,及对学习物理的兴趣和掌握科学的学习方法都具有重要的作用.
First, the experimental hypothesis (a) hypothesis of experiment hypothesis of physics in junior high school, mapping is an important teaching content and basic learning method throughout the teaching of force, light, electricity and magnetism, but also the basic skills to be mastered by students One of the importance and strengthen the junior middle school physics knowledge map, drawing teaching, not only is to cultivate students' understanding and mapping ability needs and ways, but also for the close physical teaching and production, the actual contact of life, vivid for the students through the image Perceptual content to understand knowledge, to develop the ability of students to express graphics and observation, experimental ability, and interest in learning physics and master the scientific learning methods have an important role.
