在数学教学中,解决问题的过程就是启发学生思维、掌握数学知识、培养数学能力的过程。教师有效设计课堂提问,可以有效帮助学生形成新的数学概念,巩固与应用新知识,复习与强化旧知识,同时训练与提高学生的思维方法,增强学生的实际运用能力和创新能力。问题串是指在某一特定的学习过程中,围绕一定的目标或中心内容,根据一定的逻辑结构设计一系列问题,以问题来引导学生进行探究学习。有效的问题串能够激发学生思维,培养学习能力,优化教学结构,提高教学效率。在多年的初中数学教学实践中,
In mathematics teaching, the process of solving the problem is to enlighten students’ thinking, master the knowledge of mathematics, and develop mathematics ability. Teachers effectively designing classroom questions can effectively help students to form new mathematical concepts, consolidate and apply new knowledge, review and strengthen old knowledge, train and improve students ’thinking methods, and enhance students’ practical ability and ability to innovate. Question string means to design a series of questions based on a certain logical structure around a certain target or center in a specific learning process, and to guide students to inquiry learning with questions. Effective question string can stimulate students’ thinking, develop learning ability, optimize teaching structure and improve teaching efficiency. In many years of junior high school mathematics teaching practice,
