作为高中化学知识基础部分的化学概念、元素知识、化学原理及相应的计算、实验都有着非常密切的联系,并形成完善的知识网络体系.因此,学生只有更好的掌握化学概念,才能更好的把握化学课程结构与知识.概念图是表达概念之间关系的脉络图形,教师使用概念图教学,可以使学生实现对化学知识结构的整体把握,并使学生逐渐形成更高效的认知能力.一、概念图简述概念图是在上世纪六七十年代,由美国康奈尔大学诺瓦克
As a basic part of high school chemistry knowledge of chemical concepts, elemental knowledge, chemical principles and the corresponding calculation, experiment has a very close contact and form a complete knowledge network system .Therefore, students only better grasp of chemical concepts, to better Grasp the chemistry course structure and knowledge.Concept map is the context of expression of the relationship between the concept of graphics, teachers use the concept of teaching, can enable students to grasp the overall structure of chemical knowledge, and enable students to gradually form a more efficient cognitive skills. First, a brief description of the concept map Concept map in the sixties and seventies of the last century, by the United States Cornell University Norwalk
