Personalized exercise matching method in mobile terminal classroom teaching systems

The invention discloses a personalized exercise matching method in a mobile terminal classroom teaching systems. The method comprises the following steps of: firstly taking teaching data generated bya managed teaching system over the years as data sources of an exercise matching model; and in a personalized exercise matching process, dividing a complete learning period into three stages which adopt different matching algorithms. In the three stages, the difficulties of pushed exercises are gradually increased, and a similar exercise clustering algorithm is matched to push other exercises mostsimilar to wrong exercises for students so as to consolidate the knowledge points. According to the method, most proper exercises are intelligently pushed for students, so that the learning efficiency of students and the teaching efficiency of the teachers are greatly improved. 本发明公开了种移动端课堂教学系统中的习题个性化匹配方法。该方法首先将被管理的教学系统历年所产生的教学数据看作习题匹配模型的数据源，习题个性化匹配过程中将个完整的学习周期分为三个阶段，每个阶段采用不同的匹配算法。在三个阶段中，推送的习题难度逐渐增大，并配合相似题聚类算法为学生推送与错题最为相似
