新课程标准倡导自主探究、合作、交流与实践创新的教学学习方式。教师在教学过程中,应从学生生活经验和已有的知识背景出发创设数学情境,向他们提供充分的从事数学活动和交流机会,促使他们在自主探究的过程中真正理解和掌握基本的数学知识和技能、数学思想和方法,同时获得广泛的数学活动经验。在此活动中,教师要创设数学情境,营造数学氛围。创设情境,寻求解题途径。在数学课堂上,常常会出现对某一问题思考多时也找不到突破口、产生为难情绪的情况,这时就需教师精心创设数学情境,使学生瞬间找到解 The new curriculum standards promote self-exploration, cooperation, exchange and practice of innovative teaching and learning. In the process of teaching, teachers should create mathematical situations based on the students’ life experience and existing knowledge backgrounds, provide them with full opportunities to engage in math activities and exchanges, and enable them to truly understand and master the basic mathematical knowledge in the process of self-exploration Skills, mathematical ideas and methods, while gaining extensive experience in math activities. In this activity, teachers create mathematical situations and create mathematical atmosphere. Create situations and seek ways to solve problems. In mathematics class, often there will be a long time thinking of a problem can not find a breakthrough, resulting in embarrassing emotions, then teachers need to carefully create mathematical situations, so that students find an instant solution
