一、温故知新,衔接自然由于初中物理各章节的知识点是有内在联系的,所有在进行新课导入时必须充分联系已学的知识,采用温故知新导入新课,即以新旧知识之间的连接点为支撑,将新知识纳入已经掌握的旧知识结构中,使学生感到新知识并不陌生.正如俄罗斯著名生理学家巴甫洛夫所言:所有新问题的解决都是利用主体经验中已有的旧工具实现的.可见,包括物理在内的许多新知识是从旧知识中延伸发展而来的,因此,温故知新导入法不仅巩固了已经掌握的旧知识,而且为导入新课起到承上启下的作用.譬如,我教《电阻的串联》一课时,先引导学生复习、总结电 First, to learn new things, to connect nature Because the knowledge points of junior high school physics chapters are intrinsically linked, all the new lessons must be fully connected with the knowledge that has been learned, use the new knowledge to introduce new lessons, that is, the connection point between the old and new knowledge. In order to support the new knowledge into the old knowledge structure that has been mastered, it is no stranger for students to feel new knowledge. As the famous Russian physiologist Pavlov said: All new problems are solved by using the existing experience in the subject. Obviously, the old tools have realized that many new knowledge, including physics, have evolved from the old knowledge. Therefore, the new method of updating the knowledge of the old readers not only consolidates the old knowledge that has been mastered, but also serves as a link between the introduction of new lessons. For example, when I taught the series “resistance of resistance”, I will guide students to review and summarize electricity.
