基于手持设备的练测评系统设计与实现

The Design and Implementation of Exercise-Test-Evaluation System Based on Handheld Device

针对现有网络学习和移动学习的特点,提出了一种基于手持设备的练测评系统解决方案。提出了以最佳记忆曲线和以往答题记录为依据的智能组卷算法,并针对手持设备通信网络的不稳定性问题提出了断点续传方法。最后,在Windows CE嵌入式平台上采用SQLCE及中间件等技术实现了该系统,并通过真实环境测试证明了该系统的可用性和算法的高效性。

For the features of e-learning and mobile learning,an effective exercise-test-evaluation solution based on handheld device is presented.The solution mainly includes exercises,test,evaluation and intelligent feedback.Effectively utilizing optimal curve of memory and previous answer records,an intelligent paper composition algorithm is proposed.For the problem of instability of communication network,a broken-point continuingly-transferring method is presented.Finally,SQLCE and middleware technology are used to implement above solution in Windows CE embedded platform.The system testing with practical data confirms system availability and the efficiency of the algorithm.
