在初中物理学习的进程中,物理知识环环相扣,螺旋式上升。在学习新的知识时,学生已建有的很多知识是在前面系统学习中获得的,因而相对稳固。这为构建新的知识体系打下了良好的基础。如果我们在组织物理课堂教学中注重新旧知识对比,坚持循序渐进,螺旋式上升的原则,根据学生知识积累和能力提高的实际情况,引导学生更好的构建新的知识体系,就必将能实现初中物理课堂的三维增值。
In the process of junior high school physics learning, the physical knowledge is interlocked and spirally increased. When learning new knowledge, much of what the student has built up is relatively stable in the previous systematic learning. This laid a good foundation for building a new system of knowledge. If we pay attention to the comparison of old and new knowledge in organizing physical classroom teaching and adhere to the principle of gradual and orderly spiral and guiding students to better construct a new knowledge system according to the actual situation of students’ knowledge accumulation and ability improvement, Three-dimensional value-added physics classroom.
