一、问题背景化学是一门以实验为主的自然学科。在进行素质教育的改革大潮中,如何在化学课堂中培养学生的合作能力和创新精神,是重中之重的问题。近年来,从基础教育课程改革启动后,课堂教学强调以知识的传递和学习为基轴的教育过程,强调以个体心理品质的训练与养成为主线的发展过程,却忽视了以人际互动为中心的社会过程。针对化学学科的特点,实验多做,课堂容量小;实验少做,学生参与少等矛盾,寻求好的化学课堂模式,有必要探索合作学习在化学教学中的应用。二、合作学习与学科内容紧密结合的操作 First, the problem background chemistry is an experiment-based natural science. In the tide of reform of quality education, how to cultivate students’ cooperation ability and innovative spirit in chemistry class is the most important issue. In recent years, after the initiation of the basic education curriculum reform, the classroom teaching emphasized the education process based on knowledge transfer and learning as the basic axis, emphasizing that the development and training of individual psychological qualities became the main line of development, but neglected the use of human interaction. The social process of the center. In view of the characteristics of chemistry, experiments are done more often, classroom capacity is smaller, experiments are less done, students are less involved in such conflicts, and a good chemistry classroom model is sought. It is necessary to explore the application of cooperative learning in chemistry teaching. Second, the cooperative operation and the subject content closely integrated operation
