在问题教学中,问题的能力在于教师引导学生,启发学生,能不能以问题贯穿教学关键在于教师。教师要起到带的作用,而不能成为制约学生发展的绊脚石。 In problem teaching, the problem ability is that teachers guide students and inspire students. The key lies in teaching whether problems can be covered by teachers. Teachers should play the role of band, but not be a stumbling block to the development of students.
