“教师教学应该以学生的认知发展水平和已有的经验为基础……使学生理解和掌握基本的数学知识与技能、数学思想和方法,获得基本的数学活动经验。”数学教学应引导学生通过实践、思考、探索、交流等,获得数学的基础知识、基本技能、基本思想、基本活动经验。实验稿说的是“广泛”的数学活动经验。修订稿强调的是“基本”活动经验,它需要学生在活动化的课堂中生成,课堂上教师应引导学生多动手、多思考、多交流。基本活动经验,新修订课标中没有单独解释。专家、学者对基本经验的解释也各不相同,但他们的基本认识是相同的。
“Teacher teaching should be based on the level of cognitive development of students and existing experience ... to enable students to understand and master basic math knowledge and skills, mathematical ideas and methods and gain basic mathematical experience.” Guide students through practice, thinking, exploration, exchange, access to math basic knowledge, basic skills, basic ideas, basic activities experience. The experimental version says “a wide range of” mathematical activity experiences. The revised version emphasizes the experience of “Basic ” activity, which requires students to be generated in an activity-based classroom. In class, teachers should guide students to be more hands-on, more thinking and more conversational. Basic experience, the newly revised curriculum standard is not separately explained. Experts and scholars have different interpretations of basic experiences, but their basic understanding is the same.
