Upbringing program for the concept of atom/molecule amd the developmentof teaching materials.

我们从一个关于原子和分子的问卷中得到了两个结果。我早期认识的人是被动的。原因是他们只相信老师的话。当他们经历了对一种现象的理论试验后，他们就进入了下一个阶段。识别离子是次等的。在初中学习离子是很困难的。我们检查了有关原子和分子存在的教材。1)布朗运动的分析2)根据渗透压规律区分电解质和非电解质这些实验在化学史上是很重要的，我们需要把它们作为教材来复习。我们对教材中存在的原子和分子粒子进行思考，利用膜通过的原理。

We got two results from a questionnaire about atom and molecule.I Early understanding person is passive.The reason is because only they believed words of a teacher. When they experienced a theoretical trial for a phenomenon, they go to the next stage.II It is inferior to recognise on ion.It is difficult the learning of ion in a junior high school. We examined the teaching materials about existence of atoms and molecules.1) Analysis of Brownian movement2) A difference of an electrolyte and a nonelectrolyte by a law of osmotic pressure. There experiments were important with the chemical history, and we need to review it as the teaching materials. We think about the teaching materials for the existence of a particle of atom and molecules to utilize a principle of membrane passage.
