【摘要】：随着信息时代的到来,计算机技术、互联网技术和多媒体技术的飞速发展,世界上各式各样的信息呈几何级数增长,而且增长的速度仍在加快,Google服务器每天处理的数据量已超过24PB,这意味着Google每天处理的数据是美国国家图书馆纸质出版物上千倍的数据量,因此,终身学习已经成为一种广受认可的生活方式。自2012年MOOC元年以来,全球掀起MOOC风潮,MOOC教育模式为人们获得优质教育资源提供了均等的机会,MOOC已成为炙手可热的研究领域之一,知识共享时代已经来临。本文首先对课题的研究背景、国内外的MOOC研究现状进行了回顾与介绍。分析了辅助学习系统所涉及的相关理论,介绍系统开发所采用的关键技术,结合当前学校的教学实际情况,深入探讨教师、学生、系统管理员三者在课程辅助学习系统中的作用,围绕“教”与“学”两大核心功能,从三种不同角色角度详细分析系统功能需求,运用软件工程结构化设计思想,给出了系统的组织结构图,完成了数据库设计,使用LAMP等前沿开源开发技术,设计开发出一个面向MOOC,基于B/S结构的课程辅助学习系统。介绍了系统管理、用户管理、课程管理、题库试卷四个核心模块的设计与实现,完成系统的配置,对每个子模块的功能进行测试验证。最后,对系统开发过程中所取得的成果进行总结,系统存在的问题和不足进行反思,提出系统进一步改进的方向,并对今后的研究工作进行了展望。面向MOOC的课程辅助学习系统具有界面友好、操作简单、良好的交互性、安全稳定等优点,满足教师教学,学生学习,同时还能随时随地完成课程考试的要求,实现了让求学者轻松实现获取知识的目的,课题的研究具有重大意义。
[Abstract]:With the advent of the information age and the rapid development of computer technology, Internet technology and multimedia technology, all kinds of information in the world are growing in geometric series. And the growth is still accelerating, and the amount of data that the Google server handles every day exceeds 24 PBs, which means that Google processes thousands of times as much data per day as the National Library of America's paper publications, so, Lifelong learning has become a widely accepted way of life. Since the first year of MOOC in 2012, the global MOOC education model has provided equal opportunities for people to obtain high-quality educational resources. MOOCs have become one of the hottest research fields, and the era of knowledge sharing has come. In this paper, the background of the research and the current situation of MOOC research at home and abroad are reviewed and introduced. This paper analyzes the relevant theories involved in the auxiliary learning system, introduces the key technologies used in the development of the system, and discusses deeply the teachers and students in combination with the actual teaching situation in the present school. The function of the system administrator in the course aided learning system, focusing on the two core functions of "teaching" and "learning", analyzes in detail the functional requirements of the system from three different roles, and applies the idea of structured design of software engineering. The organization chart of the system is given, the database design is completed, and a course aided learning system based on the B / S structure of MOOC, is designed and developed by using the advanced open source development technology such as LAMP. This paper introduces the design and implementation of the four core modules of system management, user management, curriculum management and examination paper, completes the configuration of the system, and tests and verifies the functions of each sub-module. Finally, the paper summarizes the achievements in the development of the system, reflects on the existing problems and shortcomings of the system, puts forward the direction of further improvement of the system, and looks forward to the future research work. The course aided learning system oriented to MOOC has the advantages of friendly interface, simple operation, good interaction, safety and stability. It can meet the requirements of teachers' teaching and students' learning, and at the same time, it can complete the course examination anytime and anywhere. The purpose of acquiring knowledge can be easily realized by scholars, so the research of this subject is of great significance.
