【摘要】：信息技术与教育的深度融合发展,开辟了资源建设与共享的新视野。然而,当前教育信息资源虽数量庞大,但整体质量不高,且缺乏对学习者的引导,容易使其出现"信息迷航",导致资源使用效益低下。针对这些问题,文章提出将用户标注应用于教育信息资源建设的解决思路。通过文献研究确定资源标注的指标,进而构建用户资源标注模型并进行了阐释。在此基础上,提出资源标注得分的计算办法,并通过计算机编程对模型的具体运行情况进行仿真模拟。结果表明,用户资源标注模型是合理有效的,标注结果能向用户提供多元化反馈,在促进学习者基于资源的自主学习、帮助教师推荐资源和提供个性化指导、促使企业改进资源质量等方面发挥作用,从而提高教育信息资源的质量和使用效益。
[Abstract]:The deep integration of information technology and education has opened up a new vision of resource construction and sharing. However, although the quantity of educational information resources is huge, the overall quality is not high, and it lacks guidance to learners. It is easy to make it appear "information confusion", resulting in low efficiency in the use of resources. This paper puts forward the solution of applying user tagging to the construction of educational information resources, determines the index of resource annotation through literature research, and then constructs and explains the model of user resource annotation. This paper puts forward a method to calculate the score of resource tagging, and simulates the specific operation of the model by computer programming. The results show that the model of user resource annotation is reasonable and effective. Tagging results can provide multiple feedback to users and play a role in promoting learners' resource-based autonomous learning, helping teachers to recommend resources and providing personalized guidance, and promoting enterprises to improve the quality of resources. So as to improve the quality and use of educational information resources.
