《义务教育数学课程标准》明确提出:“动手实践、自主探究与合作交流是学生学习数学的重要方式。”而课堂教学是落实素质教育的主渠道。它体现了教材、教师和学生三者之间的关系。在教学过程中,教师要通过教材确立三维目标,把学生当成学习的主体。在近几年的数学课改中,我们要注意引导学生在数学学习中自主探究,注重教师的专业化发展,使学生真正成为学习的主人。 “Compulsory Education Curriculum Standards” clearly put forward: “Hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics ” and classroom teaching is the main channel for the implementation of quality education. It shows the relationship between teaching materials, teachers and students. In the process of teaching, teachers should establish the three-dimensional goal through the teaching materials and regard the students as the main body of study. In the course of mathematics reform in recent years, we should pay attention to guiding students to explore their own in mathematics study, pay attention to the professional development of teachers, so that students truly become the masters of learning.
