中国的基础教育正从“知识本位”时代走向“核心素养”时代,为了更好地促进学生核心素养的发展,课堂教学离不开数学问题的设计。结合基于问题解决的“301515”课堂模式,阐述对问题教学实践中的认识和感悟。 China’s basic education is moving from the “knowledge-based” era to the “core quality” era. In order to better promote the development of students’ core qualities, classroom teaching is inseparable from the design of mathematical problems. Combined with the “301515” classroom model based on problem solving, this paper expounds the understanding and comprehension of problem teaching practice.
