随着新课程改革的不断深入,教师的改革意识与日俱增,教师在教学过程中与学生积极互动、共同发展,给学生提供机会、创造机会,使学生成为学习数学的主人,而教师则由传统教学中的“主演加导演”逐渐转变成为“组织者”、“引导者”、“合作者”。教师的角色变了,学生的学习方式也变了。新的教师角色、新的学生学习方式,要求教师要采取相应的教学策略。 With the continuous deepening of the reform of the new curriculum, teachers are constantly increasing their awareness of reform. Teachers actively interact and develop with the students in the process of teaching so as to provide opportunities for students to create opportunities for them to become masters of mathematics learning. Teachers, on the other hand, “Starring plus director ” gradually become “organizer ”, “leader ”, “collaborator ”. The role of teachers has changed, and the way students learn has changed. The new teacher role, new student learning methods, require teachers to take appropriate teaching strategies.
