学生是数学学习的主人,教师是数学学习的组织者、引导者和合作者。学生在学习过程中是否积极有效地参与课堂活动,是评价教师的组织、引导作用发挥如何的重要依据。从教的角度说,教师应努力创造适合学生主动参与的教学环境,让学生在观察、思考、猜测、验证、推理等数学活动中经历学习过程,形成积极的情感体 Students are the masters of mathematics learning, teachers are the organizers, guides and collaborators of mathematics learning. Students in the learning process is actively and effectively participate in classroom activities, is to evaluate the teacher’s organization, the guiding role of how to play an important basis. From the teaching point of view, teachers should strive to create a teaching environment suitable for students’ active participation and enable students to go through the learning process in the mathematical activities of observation, thinking, speculation, verification and reasoning to form a positive emotional body
