摘 要 “对分课堂”是复旦大学张学新教授提出一种新的课堂教学模式,它将传统课堂和讨论课堂相结合,将该模式运用于大学数学基础课“概率论与数理统计”教学能有效激发学生的学习兴趣和学习积极性,活跃课堂气氛,培养学生自主学习能力,提升学生核心素养。在实施过程中,“对分课堂”需要教师不断提升自身综合素质做好角色转变,处理好讲授、内化吸收、讨论三个环节中的每个细节,并根据学生学习情况及时调整教学内容和方法,提高课堂效率。

Abstract "Bisection class" is a new classroom teaching mode proposed by Professor Zhang Xuexin of Fudan University. It combines the traditional classroom with the discussion class, and applies this mode to the teaching of probability theory and mathematical statistics, which is a basic course of university mathematics. It can effectively stimulate students' interest and enthusiasm in learning, activate the classroom atmosphere, cultivate students' autonomous learning ability, and improve students' core literacy. In the process of implementation, "Bisection class" requires teachers to continuously improve their comprehensive quality, do a good job in role transformation, deal with every detail in the three links of teaching, internalizing absorption and discussion, and timely adjust the teaching content and methods according to the students' learning situation, so as to improve the classroom efficiency.

“概率论与数理统计”是我国高等院校理工类、经管类各专业的一门重要的公共基础课。学生普遍反映尽管高中学过部分概率内容,但是大学里从引入随机变量来研究随机现象统计规律性后,概念繁多,内容抽象,逻辑性强,学习渐渐失去了兴趣,产生畏难情绪。如果教师还是以传统的“满堂灌”教学模式,容易出现课堂上玩手机、打瞌睡、出勤率低、挂科率高的现象。
1“对分课堂”教学模式的含义
“对分课堂”教学模式是2014年由复旦大学张学新教授提出一种新的教学模式。其核心理念是通过教与学的对分和课堂时间的对分,鼓励学生自主性学习,教师引导学生学习,“授之以渔”以提高课堂效率和教学质量。具体做法是将教学分為三个阶段:(1)讲授阶段(Presentation);(2)内化吸收阶段(Assimilation);(3)讨论阶段(Discussion),简称PAD课堂。课堂时间分成两半,一半给教师讲授知识点,一半给学生讨论,讲授和讨论时间可以错开,中间留有充足时间给学生课下自主性学习。……
