进入高中阶段,大部分学生都感到学习化学非常吃力,尤其是刚开校的一个月,对接触到的“物质的量”“摩尔”这个概念感到百思不得其解,无法适应高中的课堂教学。高中化学,与初中化学相比有着本质的区别:课堂容量加大,知识面设计广,实验操作和思维度高,知识体系繁杂而又有深度。同时,它相对于数学和物理学科,又具有文科类特点:各种物质的物理性质,化学性质,化学方程式,这些基本概念抽象而又有难度,仅靠机械
Most students in the high school stage feel that it is very difficult to learn chemistry. Especially in the first month of school, they feel puzzled and unable to adapt to the concept of “quantity of matter” and “mole” High school classroom teaching. Compared with the junior high school chemistry, high school chemistry has the essential difference: the capacity of the classroom is increased, the design of the knowledge plane is wide, the experimental operation and thinking are high, and the knowledge system is complicated and deep. At the same time, it is relative to the math and physics disciplines, but also has the characteristics of the arts: the physical properties of various substances, chemical properties, chemical equations, abstract and difficult to abstract these basic concepts, only by mechanical
