一、设计理念本节课从实际生活情境出发,经历设置情境提出问题——建立模型解决问题——抽象概念理解应用——归纳总结提升认识的递进过程,通过类比数轴建立平面直角坐标系,认识点与坐标的一一对应关系.在探究问题中,利用类比的方法,培养学生提出问题、分析问题、解决问题的能力,并帮助学生提高归纳总结能力、抽象概括能力以及独立思考和合作交流的能力.二、教学设计教学目标:(1)初步掌握平面直角坐标系及相关概 First, the design concept This lesson from the actual life situation, experience setting the situation to ask questions - to establish a model to solve the problem - the abstract concept of understanding and application - induction to enhance the understanding of the progressive process, through the analog axis to establish a rectangular system, Recognize points and coordinate one by one correspondence.In the question of inquiry, the use of analogy method, training students to ask questions, analyze problems, solve problems, and to help students improve the ability to summarize, abstraction ability and independent thinking and cooperation and exchange Second, the teaching design teaching objectives: (1) the initial master plane rectangular coordinate system and related
