高中化学课程改革的目的是提高全民的化学素养,同时为学生以后学习化学打下必备的知识基础,并培养其应有的学习能力。而过去的课堂教学总是用知识结果代替知识形成过程,教师的讲占课堂时间的绝大部分,教师将知识重点及难点嚼烂后喂给学生,而学生只是被动地听、记、练,缺少独立、自主的实践和体验,使学生的学习活动不能主动,最后导致他们根本不想主动学,更不知道从此过程中获得学习的 The aim of the high school chemistry curriculum reform is to improve the general public’s chemical literacy, and at the same time lay the necessary knowledge base for students to learn chemistry in the future and cultivate their proper learning ability. In the past, classroom teaching always used knowledge results instead of knowledge formation process. Teachers’ lectures accounted for most of the classroom time. Teachers focused on the difficulty and chewing of knowledge and fed them to students. Students just listened, remembered and practiced passively. Lack of independent and autonomous practice and experience has made students’ learning activities unsuccessful. Eventually, they did not want to actively study, nor did they know that they learned from this process.
