《数学课程标准》要求:数学教学要紧密联系学生的生活实际,从学生的经验和已有知识出发,创设生动有趣的、有助于学生自主学习、合作交流的情境。让学生在观察、操作、合作、交流、反思等生动具体的活动情境中逐步体会数学知识的产生、形成与发展的过程,获得积极的情感体验,感受数学的能力,同时掌握必要的基础知识与基本技能。在教学中,教师应充分理解数学课程标准的要求,重视问题情境的创设,在情境中引导学生思考问题、探索新知,形成正确的学习方式,体验学习数学的快乐,获得终身学习和发展的动力和能力。本文我从创设认知冲突、实践活动、故事、联系生活、试验情境等方面探讨如何创设课堂中的有效情境。
The standard of mathematics curriculum requires that mathematics teaching should be closely linked with the students ’actual life. Based on the students’ experiences and existing knowledge, the teaching of mathematics should create vivid and interesting situations that help students to learn independently and exchange information. Let students gradually understand the process of generation, formation and development of mathematical knowledge in the vivid and specific activities such as observation, operation, cooperation, exchange and reflection. They should gain positive emotional experience, feel the ability of mathematics, and master the necessary basic knowledge basic skills. In teaching, teachers should fully understand the requirements of mathematics curriculum standards, attach importance to the creation of problem situations, guide students to think in situations, explore new knowledge, form correct learning methods, experience the joy of learning mathematics and gain the power of lifelong learning and development And ability. In this paper, I discuss how to create effective situations in the classroom from the aspects of cognitive conflict, practical activities, stories, connected life and experimental situations.
