美国著名科学家加波普尔说:“科学与知识的增长永远始于问题。”提问是课堂教学的重要环节,也是教师促进学生思维、增强课堂参与性的基本手段。在小学数学课堂中设计有效的提问,可以促进学生有效探究、深入思考,提高课堂教学效率。然而,有很多数学老师在教学中存在低效提问、无效提问、重复提问的现象,影响着学生学习效果的提升,长此以往,必将阻碍学生的进步和发展。因此,教师在教学中应优化提问的技巧,避免冗余提 Gabriel, a famous American scientist, said: “The growth of science and knowledge always starts with problems.” Questioning is an important part of classroom teaching and is also the basic means by which teachers can promote students' thinking and enhance their participation in the classroom. Designing effective questions in the elementary mathematics classroom can promote students to effectively explore, think deeply and improve the efficiency of classroom teaching. However, there are many math teachers in the teaching of inefficient questioning, invalid questioning, repeated questions, affecting the learning effectiveness of students, in the long run, will hinder the progress and development of students. Therefore, teachers should optimize the questioning skills in teaching and avoid redundant mention
