排列、组合与二项式定理,属于离散数学初步,学生在学习过程中普遍反映“好玩而难学”,感觉“听得懂但做不来”,加之在求解过程中疏而不慎,往往导致审题不清或者解题思路有误.分析其原因,主要是因为学生没有很好地认识到在具体数学方法上,学习这部分内容有别于学习其他章节,而且 Arrangement, combination and binomial theorem belong to discrete mathematics preliminary. Students generally reflect “fun and hard to learn” in the learning process, and feel “understand but cannot do it”, coupled with carelessness in the solution process. This leads to unclear questions or misunderstandings in the problem-solving process. The reason for the analysis is mainly because students do not recognize well that in the specific mathematical method, learning this part is different from learning other chapters, and
