《义务教育数学课程标准(2011年版)》指出“:数学活动经验的积累是提高学生数学素养的重要标志。帮助学生积累数学活动经验是数学教学的重要目标,是学生不断经历、体验各种数学活动过程的结果。”数学教学过程的指向是积累经验,实现这个目标的过程是经历数学学习过程。一、在情境观察中顺应已有的数学活动经验数学活动经验需要在做的过程和思考的过程中积淀,教学必须以学生的认知发展水平和已有的经验为基础,这是教师应遵循的课程理念。符合学生的兴趣需要、适合学习者
“Mathematical Curriculum Standard for Compulsory Education (2011 Edition)” states: “The accumulation of experience in mathematical activity is an important indicator to improve students’ mathematical literacy to help students accumulate experience in mathematics activities is an important goal of mathematics teaching is that students continue to experience the various The result of the process of mathematical activity. ”" The teaching of mathematics points to gaining experience and the process of achieving this goal is through the process of mathematical learning. First, in situational observation to adapt to the experience of existing mathematical activities Mathematical activities need experience in the process of doing and thinking of the process of accumulation, teaching must be based on the level of cognitive development of students and existing experience, which is the teacher should follow Course concept. In line with the interest of students, suitable for learners
