课堂观察中发现,互动通常是由教师发起的,由学生占主导的互动,特别是以学生发问为源头的交流很少见。师生互动的热闹表象,难掩学生学习的被动。让学生主动发问,教师应打造安全的环境,创设好玩的活动,提供思辨的视角。这表面上看是教学组织形式一种创新,实则是为了唤醒学生的主体意识,让他们对数学知识有深入的理解,对数学现象和规定有深入的思考,对理性精神有深入的感悟。 In the classroom observation, it is found that the interaction is usually initiated by the teacher. The interaction led by the students, especially the students’ questions, is rare. Lively interaction between teachers and students appearance, conceal students passive learning. Ask students to ask questions actively. Teachers should create a safe environment, create fun activities and provide a speculative perspective. On the surface, this is an innovation in the form of teaching organization. In fact, it is to awaken students’ subjective consciousness, to have a thorough understanding of mathematical knowledge, to think deeply about mathematical phenomena and regulations, and to have a deep understanding of rational spirit.
