摘要
在“双减”背景下,为使学生掌握有效的数学学习方式,教师需要思考如何提升课堂教学的质量和效率。知识的对偶性、知识的层进与拓展、知识的传承与进化,使数学学习“知新温故”。知识产生的动力方式、知识运行的自然脉络、知识形式的逐级抽象、知识内涵的理解表征和知识本质的模式凝练,使得数学教学“知新温故”。这一发现启示教师基于知识分析和心理分析以学定教,在数学教学中实现“减负增效”,从而提升学生的数学素养。基于循证研究的实践也表明这种做法是行之有效的。
ion of knowledge form,the understanding and representation of knowledge connotation and the concise mode of knowledge essence make mathematics teaching "learn new knowledge and review old knowledge".This discovery enlightens teachers to teach by learning based on knowledge analysis and psychological analysis and reduce burdens and increase efficiency in mathematics teaching,thus improving students'mathematics competency.Practice based on evidence-based research also shows that this approach is effective.
