问题是数学思维的起点,数学教学是思维的教学,数学问题设计的有效性,将直接影响教学效果。作为数学教师,要善于设计有效的数学问题,创造出适合学生主动参与、积极学习的课堂氛围,提高课堂教学效果。什么样的数学问题设计才算“有效”?除了依据教学目标、数学学科特点,具有必要的形式外,至少应满足以下几个特征:一、问题设计应有启发性教师在设计问题的时候,应使问题有一定的启发性,不仅要激发学生的好奇心、求知欲,而且要设置学生“最近发展 The problem is the starting point of mathematical thinking, mathematics teaching is the teaching of thinking, the effectiveness of the design of mathematical problems, will have a direct impact on teaching effectiveness. As a math teacher, we should be good at designing effective math problems and create a classroom atmosphere that is suitable for students to take the initiative to participate in and actively learn, so as to improve the effectiveness of classroom teaching. In addition to the teaching objectives, mathematical characteristics, with the necessary form, at least should meet the following characteristics: First, the design of the problem should be inspired by the teachers in the design of the problem Time should make the problem a little enlightening, not only to stimulate students’ curiosity, curiosity, but also to set the students ”recent development
