摘 要: 网络实验教学是教育信息化环境下大学生掌握理论知识、形成综合实践能力的重要手段,现代网络实验教学平台多是通过作业、测试的方式进行教学评价,仅通过学生成绩对教学效果进行检验是不合理的。文中构建完善的网络实验教学评价体系,使用数据挖掘技术设计网络实验教学评价系统,以此挖掘网络实验教学中有价值的信息作为原始数据,并且处理原始数据,实现评价结果的输出,从而实现全面评价网络实验教学的效果,进一步科学、合理地完善网络实验教学的评价和管理,进一步提高人才培养质量。

Abstract: The network experimental teaching is an important way for college students to master theoretical knowledge and shape comprehensive practical ability under the environment of educational informationization. The modern network experimental teaching platform performs teaching evaluation mainly by means of homework and test. However, it is unreasonable to evaluate the teaching effect only by students′ achievement. In view of this, a perfect network experimental teaching evaluation system is built in this paper, which is then designed on the basis of data mining technology, and the valuable information in the network experimental teaching is mined as the original data. Then, the original data is processed to realize the output of evaluation results, so as to evaluate the network experimental teaching effect comprehensively, and further improve the network experimental teaching evaluation and management scientifically and reasonably, and improve the quality of personnel training.

隨着“互联网+教育”、网络课程、MOOC、虚拟仿真教学和在线学习平台在高校的广泛应用,与之对应的网络实验教学平台也得到快速发展。网络实验教学平台不仅实现了教学资源共享,还能够整合教学资源,促进师生更密切的沟通与交往,有效弥补了传统课堂互动环节,使教师教学质量和学生学习兴趣得到提高。因其所具备的这些优势及高校对实验教学质量的重视,网络实验教学平台逐渐被更多的高校关注。目前,网络实验教学平台在教学评价方面有所欠缺,主要体现在网络实验教学评价体系不够完善、评价主体单一,对网络实验教学中产生的海量数据缺乏有效的分析和关联挖掘,不能为网络实验教学和管理提供决策建议。……
