一、前言
在当今数字化时代，互联网技术的快速发展以及移动设备的普及，为在线教育提供了新的契机。微信小程序和安卓APP等移动应用已经成为人们获取教育资源的重要途径。特别是在高校环境中，学生、老师和管理人员都需要一个便捷的平台来进行课程管理、学习和交流。因此，开发一款针对课程学习的微信小程序/安卓APP具有鲜明的必要性。
尽管目前已经存在一些课程管理工具，但它们主要集中在简单的信息发布和作业提交上，无法满足多元化和个性化的学习需求。此外，这些工具通常只提供基础的课程信息管理，缺乏对课程学习和作业批改的整合，使得学习过程变得繁琐且低效。因此，我们需要一个更加便捷的解决方案来解决这些问题。
本课题旨在开发一款针对课程学习的微信小程序/安卓APP，以满足学生、老师和管理人员在不同场景下的需求。具体功能包括课程分类管理、课程信息管理、课程学习管理、课后作业管理以及作业批改管理等。通过这款应用，用户可以轻松地浏览和选择课程，管理学习进度，以及跟进和评估作业完成情况。
本课题的研究意义在于提供了一个集成的在线学习平台，可以大大提高学生的学习效率，增强学习的自主性。同时，对于老师和管理人员来说，这款应用也提供了方便的工具来管理和监控学生的学习进度。此外，通过数据分析和挖掘，这款应用还可以帮助用户更好地理解学习过程，优化学习策略，提高学习效果。
