在新课改中,明确指出数学教学活动不能局限在模仿和记忆中,更应该引导学生进行自主探究、动手实践和合作交流,从而提升教学效果和教学质量。也就是说,新课标倡导学生积极主动地参与到教学实践活动中,从而培养学生的实践能力、合作能力和探究能力。合作学习作为有效教学方式,注重学生教学主体地位,有利于培养学生的人际交往能力,在数学教学实践中越来越普遍。因而,提高小组合作学习在初中数学教学中的有效性问题也成为初中数学教师所要研究的重要课题。
In the new curriculum reform, it is clearly pointed out that mathematics teaching activities can not be limited to imitation and memory, but should also guide students to carry out independent exploration, hands-on practice and cooperation and exchange, so as to enhance teaching effectiveness and teaching quality. In other words, the new curriculum advocates students to actively participate in teaching practice activities, so as to cultivate students’ practical ability, cooperation ability and inquiry ability. As an effective teaching method, cooperative learning pays attention to the status of student’s teaching and is conducive to training students’ interpersonal skills. It is becoming more and more common in mathematics teaching practice. Therefore, improving the effectiveness of group cooperative learning in mathematics teaching in junior high school has also become an important topic for junior middle school mathematics teachers.
