《数学课程标准》指出:“学生是学习的主体,教师是学习的组织者、引导者和合作者。”教师在课堂上必须找准自己的角色位置,因时因势进行点拨、指导和调控,以提高课堂教学效率,促进学生主动发展。一、捕捉动态资源,构建生成灵动的课堂课堂教学是一个蕴含着丰富课程资源的过程,这些课程资源包括:教学内容、教学设备、教师和学生等。其中有的是可以预设的,如教学用具的准备,教师自身的准备等,有的则是在课堂上动态生成的,如学生的学习表现,师生、生生互动碰撞产生 The standard of mathematics curriculum states: “Students are the main body of learning and teachers are the organizers, guides and collaborators of learning.” "Teachers must identify their own role positions in the classroom as they are instructed And regulation, in order to improve the efficiency of classroom teaching and promote students to take the initiative to develop. First, to capture the dynamic resources to build a smart classroom generated Classroom teaching is a curriculum contains a wealth of resources, these courses include: teaching content, teaching equipment, teachers and students. Some of them can be preset, such as the preparation of teaching tools, the preparation of teachers themselves, while others are dynamically generated in the classroom, such as the performance of students, teachers and students, interactive life and death collision
