问题导学是数学课堂的经典模式,也是高效课堂的一种重要模式.在问题导学中,设问非常关键,问题的质量直接影响了学生思维的发展和课堂目标的实现.但我多年对问题导学课堂进行调查研究,发现不少问题导学课堂存在很多问题,主要表现如下:(1)问题过多,过浅.课堂上产生了很多问题,使学生疲于应付,而过浅的问题又浪费了宝贵的课堂时间,导致问题教学形同虚设.(2)问题难度太大.问题的设计应该考虑到学
Problem guidance is a classic model of mathematics classroom, but also an important model of efficient classroom.In the problem-based learning, asking questions is very crucial, the quality of the question has a direct impact on the development of students’ thinking and the realization of classroom goals.But for many years, Problems Conducting a Study Conducted in the Classroom of Instructing Students and Finding Many Problems There are many problems in the class of conducting instructors. The main problems are as follows: (1) Too many problems and too few superficialities. Many problems have arisen in the classroom, which make the students tired and coping with the superficial The problem is wasted valuable classroom time, leading to the teaching of the problem in name only (2) the problem is too difficult. The design of the problem should take into account the learning
