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

我们从一份关于原子和分子的问卷中得到了两个结果。我早期对人的理解是被动的。原因是只有他们相信老师的话。当他们经历了对一种现象的理论考验后，他们就进入了下一阶段。II认识离子是次于对离子的认识。在初中，离子的学习是困难的。我们考察了有关原子和分子存在的教材。1)布朗运动的分析。2)渗透压定律对电解液和非电解液的区别。这些实验对化学史很重要，我们需要把它作为教材来复习。利用膜通道原理，对原子与分子粒子存在的教材进行了思考。

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.
