传统的数学教学一直沿用“老师讲,学生听”的模式,缺乏师生互动,没有沟通与交流。这种教学模式对学生的发展有着多种制约。课堂教学的关键就是激发学生的学习主动性,让学生积极地参与到教学过程中,使学生和老师能达到最大限度的沟通与互动。 The traditional mathematics teaching has always followed the pattern of “teachers speak, students listen”, lack of teacher-student interaction, and lack of communication and exchange. This teaching model has many restrictions on the development of students. The key to classroom teaching is to stimulate the students’ initiative in learning and allow students to actively participate in the teaching process so that students and teachers can achieve maximum communication and interaction.
