在初中阶段的化学与物理学科教学中,分子与原子教学构成了其中的重要部分.在初中化学与初中物理的课堂上,教师应当带领同学们认识分子与原子,明确分子与原子的基本特征,在此基础上构建初中生的微粒观.从本质上讲,微粒观指的是初中生运用分子或者原子的角度来看待世界,进而意识到各种物质都包含了分子与原子的基本单位.由此可见,初中物理与化学的学科教学应当把培育初中生的微粒观作为重要任务,通过运用分子与原子教学的方式来构建初中生的微粒观,提升初中生对于物理与化学现象的认知程度. In junior high school chemistry and physics teaching, molecular and atomic teaching constitute an important part of the junior high school chemistry and junior high school physics class, teachers should lead students to recognize molecules and atoms, clear the basic characteristics of molecules and atoms, On the basis of this, we construct the concept of particles for junior high school students.In essence, the concept of particles refers to the junior high school students use the molecular or atomic point of view of the world, and then realized that a variety of substances contain the basic units of molecules and atoms This shows that junior high school physics and chemistry discipline teaching should focus on cultivating junior students particle concept as an important task, through the use of molecular and atomic teaching approach to build junior high school students particle concept, improve junior high school students on physical and chemical phenomena awareness .
