随着基础教育课程改革的不断深入,在课堂上培养自主、合作、探究的能力,追寻知识与能力的契合,培养学生运用数学知识解决生活问题的能力已成为数学课堂课堂教学的首要目标。那么,在倡导“减负增效”、呼唤活力课堂的今天,构建一个宽松愉悦、轻负高效的数学课堂,已成为众多老师们的共同追求。然而随着社会的发展变迁,农村小学还存在着现代化教学设备缺乏、班生规模在不断缩小、大部分教师还深受“传统教学模式”的影响、教学观念 With the continuous deepening of the reform of basic education curriculum, the ability to cultivate autonomy, cooperation and exploration in the classroom, to trace the combination of knowledge and ability, and to train students to use mathematical knowledge to solve their daily life problems have become the primary goals of classroom teaching in mathematics. Then, in advocating “reducing the burden and increasing efficiency ”, calling for the vitality of the classroom today, to build a relaxed, light and efficient mathematical classroom has become the common pursuit of many teachers. However, with the development of society, there is a lack of modern teaching facilities in rural primary schools and the scale of students in schools is shrinking. Most teachers are also influenced by the traditional teaching mode,
