俗话说:良好的开端是成功的一半。每本高中化学教材前面都有《引言》这一部分内容。教师要上好引言课,当好学生高中化学学习的引路人。美国当代著名的认知派教育心理学家奥苏贝尔认为,传统教学使得学生对教材进行机械学习的主要原因之一,是由于在学生还没有具备起固定作用的先前知识时,教师就要求他们学习某种新内容。由于学生认知结构中还没有可以与新教材建立联系的有关观念,因而使得教材内容失去了意义。因此,在进行某个具体的 As the saying goes: a good start is half done. Each high school chemistry textbook has “Introduction” in front of this part. Teachers should be good introductory class, a good guide for high school chemistry students. Ausubel, a well-known cognitive psychologist in the United States, believes that one of the main reasons why traditional teaching enables students to mechanically study textbooks is that when the students do not have the prior knowledge of a fixed role, the teacher asks them Learn some new content. Because there is no relevant concept in students’ cognitive structure to establish contact with the new textbook, the contents of the textbook can not be meaningful. So, to do something specific
