传统的课堂教学是单纯追求知识本位的教学,如今提倡“人人都能获得良好的数学教育,不同的人在数学上得到不同的发展”的理念,体现了教育教学“育人为本”的终极目标。因此,教师应着力改善学习方式,构建有利于“创生”的具有自我生长性的数学课堂,从而促进学生全面、可持续地发展。一、自主学习,初步感悟“圆的认识”备课时应考虑两点:一是学生对圆的知识认知起点在哪里?已经知道了多少?二是哪些内容 The traditional classroom teaching is simply the pursuit of knowledge-based teaching, and now advocates the concept of “everyone can get a good math education and different people get different development in mathematics”, which shows that education and teaching are “ This ”the ultimate goal. Therefore, teachers should strive to improve their learning styles and construct self-growth math classrooms that are conducive to “creation”, so as to promote a more comprehensive and sustainable development of students. First, autonomous learning, initial perception “round of knowledge ” should take into account two points during lesson preparation: First, students know where the starting point for knowledge of the circle? Already know how much? Second, what is
