教学应建立以学生为主体的课堂教学模式。把学生置于课堂的主体地位,充分发挥学生的主体作用,倡导学生自主、合作、探究的学习方式,从而提高课堂的效益。课堂提问能激发学生积极主动思考、独立探究、掌握知识、有效拓展和引申学生的思维能力。 Teaching should establish a student-centered classroom teaching model. Put the students in the dominant position of the classroom, give full play to the role of students in the main advocate of independent, cooperative and exploratory learning, thereby enhancing the efficiency of the classroom. Classroom questions can inspire students to think proactively, explore independently, acquire knowledge, effectively expand and extend students’ thinking ability.
