《数学课程标准》指出,学生是数学学习的主人,教师是数学学习的组织者、引导者和合作者。教师要积极引导学生主动参与、亲身实践、自主搜索、合作交流,改变原来课堂教育过于强调接受学习、死记硬背、机械训练的情况,发展学生搜索处理信息的能力、获取新知识的能力、分析和解决问题以及合作交流的能力。 The Mathematics Curriculum Standard states that students are masters of mathematics learning and that teachers are the organizers, guides, and collaborators of mathematics learning. Teachers should actively guide students to take the initiative to participate in, practice, independent search, cooperation and exchange, change the original classroom education is too stressed acceptance of learning, rote memorization, mechanical training, the development of students’ ability to search for information processing, access to new knowledge, analysis And the ability to solve problems and cooperate and exchange ideas.
