【摘要】：随着教育信息化的发展,教育信息以及教育数据也已成为当前教育领域中的珍宝。正是学习分析技术的提出,使这些数据发挥出了他们潜在的巨大价值。本研究是以国内外的研究成果作为基础,以数据挖掘、学术分析等为理论依据,结合实际情况构建的一个学习分析框架,并以实际案例来检验框架的应用情况,总结其在教育领域应用过程中存在的问题,分析其未来发展趋势。本研究通过对国内外学习分析技术的研究现状进行对比梳理,发现国内的相关研究还处于起步时期,针对阶段性教育的学习分析应用较少,特别是学习分析技术在应用时没有清晰而统一的框架,因此笔者整合了学习分析的六个组成要素,即数据对象(who)、数据仓库(where)、工具包(which tools)、学生学习(what do you do)、受众(to whom)、效果(with what effect),提出了一个基于“6W”的学习分析框架。首先,以数据挖掘和学术分析为参考,对框架中工具包和数据仓库进行调整与构建,其中数据仓库中的构建主要是从移动终端、社会性软件、考试评价、提交论文四个方面进行的搭建;工具包的构建也是本文的重点部分,主要从三个级别的工具进行的组建,即开发工具、专家工具、大众工具。第二,以商业智能理论为基础,对框架中的干预部分进行设计。进而得出一个综合数据挖掘、学术分析、商业智能的学习分析框架。第三,依据上述学习分析框架与其在具体案例中的应用,借用wiki平台对案例中的数据进行收集,而后采用Node XL软件对数据进行可视化分析,从而使教师可以依据分析结果对学生进行分组教学,以及任务分配。第四,在搜集应用案例的过程中,笔者考察了学习分析6W框架的应用情况后,认为此框架在应用的过程中需要重点考虑以下几点问题:(1)个人隐私的泄漏;(2)信息安全意识的普及;(3)分析数据的归属权;(4)学习分析技术标准与规范;(5)数据对象以及应用人员的道德标准;(6)操作者的技能需求。
[Abstract]:With the development of educational information, educational information and educational data have become a treasure in the field of education.It is the learning analysis technology that makes these data play their potential great value.This study is based on the domestic and foreign research results, based on data mining, academic analysis and other theoretical basis, combined with the actual situation to build a learning analysis framework, and the actual case to test the application of the framework.This paper summarizes the problems existing in its application in the field of education and analyzes its development trend in the future.By comparing and combing the research status of learning analysis technology at home and abroad, this study finds that the relevant research in China is still in its infancy, and the application of learning analysis to periodic education is less.In particular, there is no clear and unified framework for the application of learning analysis technology, so the author integrates the six components of learning analysis.In this paper, the author puts forward a study analysis framework based on "6W", that is, data objects, data Warehouse, Toolkit and which tools, students learn what do you do, audience to whomp, effect with what effectl.First of all, with the reference of data mining and academic analysis, the paper adjusts and constructs the toolkit and data warehouse in the framework, in which the construction of data warehouse is mainly from mobile terminal, social software, examination and evaluation.The construction of toolkits is also the key part of this paper, mainly from three levels of tools, namely, development tools, expert tools, public tools.Secondly, based on the theory of business intelligence, the intervention part of the framework is designed.Then a comprehensive data mining, academic analysis, business intelligence learning analysis framework.Thirdly, according to the above learning analysis framework and its application in specific cases, using wiki platform to collect the data in the case, and then using Node XL software to visualize the data analysis.Therefore, teachers can teach students in groups and assign tasks according to the analysis results.Fourthly, in the process of collecting application cases, the author studies the application of 6W frame.It is considered that the following issues should be considered in the application of this framework:: 1) personal privacy leakage (2) the popularization of information security awareness (3) ownership of analytical data / 4) Learning and Analysis Technical Standards / specifications / 5) data objects; andApply the ethical standards of the operator to 6) the skill needs of the operator.
