小学阶段的数学学习内容,涉及了大量的探索与发现、体验和交流活动,还涉及了基本的数学方法和解决问题的策略。这些学习方式、基本方法背后所牵扯到的更深层次的东西就是教师和学生整体的思维方式、交往方式。在实际的教学实践中我们意识到,这不是简单的改变学习方式的问题,而是改变我们的学习、教研文化的问题。基于这样的思考,我们的教学研究,开始重视通过研究教学现场、教研现场中的细节、偶发事件等现象,以三维教学目标预设与落实为主要 Mathematics learning at primary school involves a great deal of exploration and discovery, experience and communication, as well as basic mathematical methods and tactics to solve problems. The deeper things involved in these learning methods and basic methods are the teachers ’and students’ overall ways of thinking and communication. In the actual teaching practice, we realize that this is not a simple question of changing the way of learning, but a problem of changing our study, teaching and research culture. Based on this thinking, our teaching and research, begin to pay attention to by studying the scene of teaching, teaching and research site in the details of occasional events and so on, to three-dimensional teaching objectives and implementation of the pre-set as the main
