教学内容的展开体现知识的形成过程,是指在教学过程中,从学生已有的知识和生活经验出发,通过创设情境,让学生进行自主探索,经历观察、操作、讨论、交流、猜测、归纳、分析和整理等,从而让学生理解数学问题的提出、概念的形成和结论的产生。也就是对知识进行一种再创造的过程,以此来培养学生的探索意识、创造精神和实践能力,让学生在数学教学活动中得到发展。
The development of teaching contents embodies the formation process of knowledge, which refers to starting from the students’ existing knowledge and life experiences in the teaching process, through creating situations and allowing students to conduct independent exploration, experience observation, operation, discussion, exchange, speculation and induction , Analysis and finishing, etc., so that students understand the mathematical problems raised, the formation of concepts and conclusions. In other words, it is a process of recreating knowledge so as to cultivate students’ exploration consciousness, create spirit and practical ability, and enable students to develop in mathematics teaching activities.
