学习是不断解决问题又不断生成问题的过程,在解决问题的过程中,引导学生主动探究、积极思考,提升思维能力,在生成问题中培养学生的创新能力。通过问题导学可提高教师在教学中的主导作用,改变平铺直叙、自言自语、满堂灌、课堂气氛沉闷的教学环境,构建符合新课程理念的教学模式,激发学生学习化学的兴趣。 Learning is a process of continuously solving problems and continuously generating problems. In the process of solving problems, students are guided to actively explore and think positively, improve their thinking ability, and cultivate students’ innovative ability in generating problems. Through problem-based learning, teachers can improve their leading role in teaching, change the teaching environment of flat-speaking, self-talking, full-house irrigation, and boring classroom atmosphere, build a teaching model that meets the new curriculum concept, and stimulate students’ interest in learning chemistry.
