一、注重学生预习与自我检测课前预习是让学生自己阅读教材,凭自己的学习经验和方法来初步认识物质的量的基本内容(学生在预习中可能会将其与“质量”进行错误的类比,没有意识到他们衡量物体的范畴是宏观和微观的区别),然后在自我检测中发现“物质的量”和“物质的质量”的不同之处,并将之前学过的几个基本物理量加以区分形成有条理的知识网络。而且合理的自我检测能够帮助学生避开认知误区让学生事半功倍。
First, pay attention to the students pre-test and self-test Pre-preview is to allow students to read their own teaching materials, with their own learning experience and methods to initially understand the basic content of the amount of material (students in the preview may be with “Quality ” Wrong analogy, and do not realize that they measure the category of objects is the difference between macro and micro), and then find the difference between “material quantity ” and “material quality ” in self-testing, After a few basic physical quantities to form a structured knowledge network. And reasonable self-testing can help students to avoid cognitive errors so that students do more with less.
