提问是小学数学课堂向学生输出信息的主要途径,它是沟通教师、学生和教材的纽带。好的课堂提问能够调动学生思维的积极性,促进实践、操作、讨论等学习活动的有效实施,实现数学学习的双向互动和深度参与。核心问题是引领数学课堂的航标,它在很大程度上决定了学生的学习方式和课堂的教学效益。提问是启发式教学的主要手段,而问题则是其中的关键要素。教师在设计问题时要克服提问的琐碎性、随意性和浅层性,要在提炼核心问题上下功夫。所谓核心 Questioning is the primary way for primary school mathematics classrooms to output information to students. It is a link between teachers, students and textbooks. Good questioning in class can arouse the enthusiasm of students’ thinking, promote the effective implementation of learning activities such as practice, operation and discussion, and achieve two-way interaction and deep participation in mathematics learning. The core issue is to lead the math class buoy, which largely determines the student’s learning style and classroom teaching effectiveness. Questions are the primary means of heuristic teaching, and questions are one of the key elements. Teachers should overcome the triviality, arbitrariness and superficiality of questioning when designing problems, and work hard at refining the core issues. The so-called core
