在数学教学中,好的情境可以唤起学生相关的知识经验和解决问题的经验和策略,是学生好奇、喜欢的源泉,是学生发现的沃土。情境创设是一种动态的过程,是以培养学生问题意识和提高学生数学思维能力为主要目的的过程,它涉到素材的选取、内容的组织和呈现等方方面面,那么如何创设有效教学情境呢?我认为要抓住四个“关键词”。一、教材教材里的情境,特别是主题图,作为教材的重要组成部分,承载着编者的课程理念。因此,首先要研读教材,关注教材
In mathematics teaching, a good situation can arouse students ’relevant knowledge experience and problem-solving experience and strategy. It is a source of curiosity and love for students and a fertile ground for students’ discovery. Situational creation is a dynamic process. It is the process of cultivating students ’problem awareness and improving students’ ability of thinking in mathematics. It involves the selection of materials, the organization and presentation of contents, and so on. How to create effective teaching situations? I think to grab four “key words ”. First, the textbook textbook context, especially thematic map, as an important part of the textbook, carries the editor’s idea of the curriculum. Therefore, we must first study textbooks, textbooks
