我国已经推行了新课程改革计划,在这种背景下,学校和教师都开始着重强调学生自身的积极性,自觉性和创造性。越来越多的教师开始认识到教师在课堂教学中只是起到一个主导的作用,学生才是课堂真正的主体。为了使学生的主体地位能够更加凸显,这就要求教师应当更加有效地创设问题情境,从而激发学生的积极性,使学生有更加充分的活动机会。 In our country, the new curriculum reform plan has been implemented. Under this background, both schools and teachers have begun to emphasize their own initiative, consciousness and creativity. More and more teachers begin to realize that teachers play a leading role in classroom teaching, and students are the real main body of the classroom. In order to make students’ subjective position more prominent, this requires that teachers should create problem situations more effectively, so as to stimulate their enthusiasm and make students have more opportunities for activities.
