美国教育家布鲁纳说:“我们十分强调学生主动学习,学生亲自探索事物,即所重视的是主动地发现而不是被动地接受知识。”它启发我们在教学实践中,必须改革传统的教学方法,优化课堂结构,以充分发挥学生的主体功能,从而提高课堂效率。要使课堂结构达到高效,应构成一个“环环紧扣、层层入深、步步有新、相互促进”的有机整体。基于此,结合数学教学实践,我认为应做到以下几点:一、创设情境,激发学生自主探究创设与数学教学内容相关的情境,相当于为学生学习提供促 Bruener, an American educator, said: “We place great emphasis on students’ active learning and students exploring things by themselves, that is, what they value is taking the initiative to discover, rather than passively, their knowledge.” It inspired us to reform the tradition in teaching practice Teaching methods to optimize the classroom structure, in order to give full play to students’ main functions, so as to improve classroom efficiency. In order to make the classroom structure efficient, it should form an organic whole with tightly interlocking rings, layers of layers, new steps and new ways of mutual promotion. Based on this, combined with the practice of mathematics teaching, I think we should do the following: First, create the situation to stimulate students to explore and create the context of mathematics teaching content, equivalent to provide students with learning to promote
