现代教育的理念改变了教师以往灌输者的角色,教师是课堂教学的主导者,而不是主宰者。要从传统“授人以鱼”变为“授人以渔”的角色,做学生学习的帮助者和合作者,把学习的主动权交给学生。教学要体现学生的主体地位,学生不再是消极地、被动地接受教育,而是主动参与学习。学生主动参与学习是学生真正成为数学学习的主人的前提,关系到数学学习的成败。学生只有通过亲身的主动参与,自主探索,才能获得新知识,培养各方面的素质能力,才能真正对数学学习感兴趣。教师要善于激 The concept of modern education has changed the role of teachers as inculcators in the past. Teachers are the dominant and not the dominant ones in classroom teaching. From the tradition of “empowering people” to “empowering others”, they should help their learners and collaborators and give students the initiative they need to learn. Teaching should reflect the dominant position of students, students are no longer passively, passively to receive education, but take the initiative to participate in learning. Students take the initiative to participate in learning is the premise for students to truly become the masters of mathematics learning, related to the success or failure of mathematics learning. Only by taking the initiative to participate in self-exploration, students can acquire new knowledge and develop all aspects of the quality of ability in order to truly interested in math learning. Teachers should be good at excitement
