著名数学家哈尔莫斯有一句名言:问题是数学的心脏。的确,问题是教学的出发点,是思维的起点,是贯串整个教学过程的源动力,数学课堂因问题而富有生机与活力。教学中教师以问题作为课堂教学的主线已成为人们的共识,学生从问题出发去探索、交流,课堂教学在不断提出问题与解决问题的过程中发展学生的思维品质。一、创设合适问题,提高学生思维的深刻性何谓合适的问题,即问题与学生的认知水平相适应,处于学生的最近发展区,大小适宜、难易适当。合适的问题设 Harmus famous mathematician has a saying: the problem is the heart of mathematics. Indeed, the problem is the starting point of teaching, the starting point of thinking, the source driving force of the whole teaching process, and the mathematics classroom full of vigor and vitality due to problems. Teachers in teaching as the main theme of classroom teaching has become the consensus of people, students from the problem to explore and exchange, classroom teaching in the process of raising questions and solving problems in the development of students’ thinking quality. First, the creation of appropriate questions to improve the profound thinking of students What is the appropriate question, that is, the problem with the cognitive level of students to adapt to the students in the recent development zone, the appropriate size, easy to appropriate.
