课堂教学中的板图,不是可有可无的陪衬,而是整个课堂教学的有机组成部分。它和教师的课堂演示、口头讲述以及演算论证相辅相成,可以帮助学生直观形象地领会所述内容,既学到物理知识,又增长了分析问题解决问题的能力;同时,也使学生从中学到表达、研究物理问题的方法。尽管目前有各种挂图、幻灯片,甚至科教影片作教学的先进手段,但板图的作用仍是不可忽视和低估。而且,板图的某些作用,是这些先进手段所代替不了的。物理教学中常见的板图有各种示意图、受力分析图、电路图、光路图、电场或磁场的力线图等类型,以及各种图像、能级图、矢量分析图等。其中使用最广泛的是各种示意图。但无论哪类图,都应具备以下特点,才
The board map in class teaching is not dispensable, but an integral part of the entire classroom teaching. It complements the teacher’s classroom presentations, oral presentations, and calculus arguments. It can help students understand the content intuitively, learn physical knowledge, and increase the ability to analyze problems to solve problems; at the same time, it also enables students to learn from expressions. , study methods of physical problems. Although there are various kinds of flip charts, slides, and even advanced teaching methods for teaching videos, the role of the plans cannot be ignored and underestimated. Moreover, some of the effects of the maps cannot be replaced by these advanced methods. The board diagrams commonly used in physics teaching include various schematic diagrams, force analysis diagrams, circuit diagrams, optical path diagrams, force diagrams of electric or magnetic fields, and various types of images, energy level diagrams, vector analysis diagrams, and the like. Among the most widely used are various schematic diagrams. But no matter what kind of map, it should have the following characteristics,
