本节内容是从微观的角度来研究物质的结构,比较抽象,内容较多,理论较深,又要符合现代物质结构理论的观点,因此在教和学两方面都存在比较大的困难。怎样搞好这一节的教学,为学生下一步的学习打好基础?我教学以后有这样几点体会: 一、应特别加强语言的直观性,运用形象的比喻帮助学生理解和加深记忆。比 The content of this section is to study the structure of matter from the microscopic point of view, with more abstraction, more content, deeper theory, and in conformity with the viewpoints of modern material structure theory. Therefore, there are relatively great difficulties in both teaching and learning. How to do a good job in this section of teaching, lay the foundation for the students to learn the next? My teaching later have some experience: First, should be particularly to strengthen the visual language, the use of image metaphor to help students understand and deepen the memory. ratio
