《数学课程标准》指出:“数学教学是数学活动的教学。教师要紧密联系学生的生活环境,从学生的经验和已有的知识出发,创设生动的数学情境……”。因此,我们要以教材为依据,要从学生的生活经验和已有的知识背景出发,挖掘学生生活中可供教学之用的素材,让学生的生活经验成为教学中的重要资源。这就要求我们在数学教学中,千方百计地创设恰当的教学情境。在日常教学中我始终根据教学内容的特点,从学生已有的知识和生活经验出发,联系学生的生活实际,以音像、图画、故事、游
The standard of mathematics curriculum states: “Mathematics teaching is the teaching of mathematics activities. Teachers should closely contact students ’living environment and create vivid mathematical situations based on the students’ experience and existing knowledge.” Therefore, based on the teaching materials, we should start from the students ’life experience and the existing knowledge background, and tap the materials available for teaching in the life of students so as to make the students’ life experience an important resource in teaching. This requires that we do everything possible to create a proper teaching situation in mathematics teaching. In daily teaching, I always based on the characteristics of the teaching content, starting from the students ’existing knowledge and life experience, contact with students’ actual life, with audio-visual, pictures, stories, travel
