社交媒体环境下学术型用户生成内容质量评估研究

[目的/意义]探索如何对社交媒体上学术型用户生成内容质量进行评价。[方法/过程]首先,通过招募使用过社交媒体上学术信息的用户,开展学术信息检索用户实验,获取用户评价学术型用户生成内容质量的指标,构建初始质量评价指标体系;其次,通过问卷调查收集各评价指标的重要性;最后,利用主成分分析法得出模型中的评价指标及其权重。[结果/结论]构建了适用于学术型用户生成内容质量评估的模型,该模型包括两个一级指标和11个二级指标,其中重要性程度排在前三位的指标为演示性、有趣性和合理性。研究结果丰富和完善了社交媒体学术信息质量评价理论和指标体系,为自动识别高质量学术型用户生成内容提供参考。

New Mode in Parasites Experimental Teaching --Application and Experience of Interactive Teaching with Digital Microscope System

In order to improve the parasites experimental teaching quality, Digital Microscope System is used to replace the ordinary optical microscope in the teaching of eggs, imagoes, and tissue slices. The new model of experimental teaching, integrating modem information technology into the parasite experimental teaching, gives full play to the students＇ learning enthusiasm, initiative and creativity and improves the quality of experimental teaching. And at the same time, it provides a basis for the microbiological and pathological experimental teaching reform.
