教学内容,它用以表示随机事件发生的可能性,具有较强的现实背景和与其他知识点不同的建构模式.然而,在平时教与学中,这部分本来颇具趣味的知识却时常因为“摸球掷币”般套路化的考查方式而难显风采.概率对学生而言就是掷骰子、抛硬币、摸彩球、翻扑克、玩转盘.这类练习题目既限制了概率学习的视野,也不利于知识联结的建构,使得概率学习孤立化,错失了展开多个知识点综合应用训练的契机.笔者通过观察近几年中 Teaching content, which is used to indicate the possibility of a random event, with a strong background and different from other knowledge points of the construction mode However, in teaching and learning usually this part of the original interesting but often because of the “Touch the ball throwing money,” as a routine examination of the style and difficult to show style.Probability for the students is the dice, coin toss, touch the ball, turn poker, play turntable .Exercises such topics both limit the probability of learning Of vision, nor is it conducive to the construction of knowledge link, making the probability of learning isolated, missed the opportunity to start a comprehensive application of multiple knowledge points training.I through observation in recent years
