基于学科知识图谱的信息技术在线课程设计研究

Research on Online Course Design of Information Technology Based on Subject Knowledge Graph

针对目前基础教育领域在线教学评价方式单一、学生学习反馈不及时等显著问题,结合知识图谱的特点以及学习元平台的优势,构建一门高中信息技术在线课程。该门课程充分发挥学科知识图谱的特色功能,突破传统网络课程的限制,为教师开展多元化教学评价、实现因材施教提供有力支持。从学科知识图谱的构建、课程的前期设计、课程的实施过程和课程的后期引导四个方面对在线课程的设计进行详细阐述,以期为基础教育领域在线课程的教学评价与管理提供启示。在研究中构建一门基于学科知识图谱的“信息技术基础”在线课程,并利用学习元平台进行学科知识图谱与在线课程资源的整合,通过呈现实时动态可视化的学生课程学习成绩、学习认知地图以及学习参与水平,实现在线教学评价的实时反馈和个性化指导,在一定程度上回应当前基础教育阶段在线教学评价存在的反馈不及时、学生诊断不精准的问题。

In view of such problems in the field of basic education as the single way of online teaching evaluation and the untimely feedback on students’learning,this study combines knowledge map and learning meta platform to build a high school information technology online course.This course gives full play to the functions of the subject knowledge map,overcomes the limitations of traditional online courses,and provides strong support for teachers to carry out diversified teaching evaluation and teach students according to their aptitude.This paper,in order to bring enlightenment to the teaching evaluation and management of online courses in the field of basic education,elaborates the design process of online courses from four aspects:the construction of subject knowledge map,the preliminary design,the implementation process and the later guidance.In the research,an online course of“information technology foundation”based on the subject knowledge map is constructed,with the learning meta platform used to integrate the subject knowledge map with the online course resources.By presenting the real-time dynamic and visual students’course learning achievements,learning cognitive map and learning participation level,the real-time feedback and personalized guidance of online teaching evaluation are realized.To some extent,it tries to respond to the need of solving the problems of untimely feedback and inaccurate diagnosis of students in the current online teaching evaluation in the basic education stage.
