美国教育心理学家布鲁纳提出:探索是数学教学的生命线.高中《新课程标准》提出的一个重要理念就是要积极主动、有探索精神地学习,并且通过许多不同形式的自主学习和探索活动来让学生主动地发现和创造数学中的一些问题.现在的学生在被教育的同时又要进行自主地学习、认识和发展.而我们的教育对于学生只是外部客观的东西,这时就需要带动学生自主学习,从而提高学生的素质.因此我们应当民主地进行教学,让学生在活跃的课堂氛围中思维和体验,最后让学生有效率有兴趣的获得知识.如果他们可以从老师所讲的内容中掌握方法,就能侧类旁通,自然而然的能解决很多以前不能解决的问 Bruna, an American educational psychologist, pointed out: Exploration is the lifeline of mathematics teaching.An important concept proposed by the “New Curriculum Standard” in senior high school is to actively and enlightenedly study and through many different forms of self-learning and exploration activities To enable students to find and create some math problems .Now students are educated at the same time be independent learning, understanding and development.And our education is only external and objective for students, then you need to drive Therefore, we should conduct our teaching democratically so that students can think and experience in an active classroom atmosphere and finally let students gain knowledge efficiently and interestingly.
