初中数学《课程标准》在过程目标中使用了“经历”、“体验”、“探索”等术语表述,这说明课程改革已经把教学探究提到教育的核心地位。动手实践、自主探索与合作交流是培养学生创新意识和实践能力的一个非常重要的途径,已经成为数学教学改革的一个热点。自主探索与合作交流转变了同学们“学”的方式,必然就要转变教师“教”的方式,教师必须由“传授者”“监督者”“指令者”转变为“组织者”“引导者”和“合作者”。教学过程中,教师必须要认真研究 The junior high school mathematics “Curriculum Standard” uses the terms “experience”, “experience”, “exploration” and so on in the process goal, which shows that curriculum reform has put teaching inquiry to the core of education. Hands-on practice, independent exploration and cooperation and exchange are a very important way to cultivate students’ innovative consciousness and practical abilities. It has become a hot spot in mathematics teaching reform. Autonomous exploration and cooperation and exchange have changed the way students “learn”, and inevitably they have to change the way teachers teach “teachers.” Teachers must be instructed by “mediator ” “supervisor ” “Change to ” Organizer “” Director “and ” Partner ". In the process of teaching, teachers must carefully study
