【摘要】：随着无线和移动网络的迅速发展,移动通信终端成为每个人的必备工具,移动教育软件也已经越来越普及,所以提供一款个性化练习的软件来提高学生学习效率和成绩已经刻不容缓。根据对学生学习情况的研究,一个人的所有知识和能力均可分为三个区,舒适区、恐慌区和学习区。舒适区是自己熟悉和掌握了的知识和能力,恐慌区是通过学习也不能短期内掌握的知识和能力,学习区是通过学习能够掌握的知识和能力,所以在练习过程中始终让学生在学习区中练习是帮助学生快速增长分数的方法,这是本系统的设计理论。本系统由Android前台的练习系统和Web端后台的服务管理系统共同实现。Android前台主要提供用户进行题目练习,Web后台通过使用SpringMVC框架实现对前台的服务,同时实现对题库和用户的管理。后台通过基于物品的协同过滤算法实现了对用户的个性化推荐,每一用户在练习后都有自己的历史记录和错题记录库,通过计算记录库中题目难度系数的均值,动态的调整有关题目的难度系数,再进行相关推荐,达到让用户在学习区学习的目的。本系统已经实现用户在Android前台登录、注册、练习功能,并且在练习功能中实现了推荐题目练习。管理员能够通过登录后台Web端进行题目、用户的管理,能够实现给前台用户的个性化推荐。
[Abstract]:With the rapid development of wireless and mobile networks, mobile communication terminals have become an essential tool for everyone, and mobile education software has become more and more popular. Therefore, it is urgent to provide a personalized exercise software to improve students' learning efficiency and performance. According to the study of students' learning situation, a person's knowledge and ability can be divided into three zones, comfort zone. The comfort zone is the knowledge and ability that one is familiar with and mastering, the panic zone is the knowledge and ability which can not be mastered in the short term by learning, and the learning area is the knowledge and ability that can be grasped by learning. So always having students practice in the study area during the exercise is a way to help students increase their scores quickly. This is the design theory of this system. This system is implemented by the practice system of Android foreground and the service management system of Web terminal. The Web background implements services to the foreground using the SpringMVC framework. At the same time to achieve the management of question bank and user. Background through the collaborative filtering algorithm based on articles to achieve personalized recommendation to users each user in practice have their own history and misplaced record database. By calculating the average of the difficulty coefficient of the problem in the record bank, dynamically adjusting the difficulty coefficient of the related problem, and then making the related recommendation. To achieve the purpose of user learning in the learning area. This system has realized the user login, registration, practice function in the Android foreground. The administrator can log on to the background Web end to carry out the problem, the user management, can realize the personalized recommendation to the foreground user.
