中学化学教学大纲明确要求学生必须具有绘画化学仪器图和实验装置图的能力,本文拟提出能够为学生所普遍接受的绘画化学仪器图和实验装置图的一整套方法,并粗浅的谈谈培养学生绘图能力问题。 一、化学仪器图的画法 首先应明确告诉学生,化学仪器图是示意图,不是立体的实物美术图,这样可以消除学生的畏难情绪。其次是系统地而不是零碎地讲授化学仪器图的具体、简明、易学的画法。这是培养绘图能力的关键。 化学仪器图的画法,要点有三: (一)化学仪器图应尽可能是直线的,还要有一定的绘画顺序,宛如写字有笔顺一样。或 The chemistry syllabus for middle schools clearly requires that students must have the ability to draw chemical instrument maps and experimental equipment maps. This paper proposes a set of methods that can be widely accepted by students as a set of painting chemistry instrument maps and experimental apparatus maps. Drawing ability problem. First, the drawing of the chemical instrument diagram First of all, students should be clearly told that the chemical instrument diagram is a schematic diagram, not a three-dimensional physical art map, so that students can eliminate the fear of difficulty. The second is to teach concrete, concise, and easy-to-learn paintings of chemical instrument maps systematically rather than systematically. This is the key to nurturing the drawing ability. There are three main points in the drawing of chemical instrument diagrams: (a) Chemical instrument diagrams should be as straight lines as possible, but also have a certain sequence of paintings, just like writing strokes. or
