试论信度分析在毕业生追踪调查中的应用

开放教育毕业生追踪调查利用3个量表问卷从从社会用人单位和毕业生的视角，对开放教育试点人才培养方式及其质量进行了调查、审视和评价。其调查结果不仅可以科学、客观地评价远程开放教育的教学质量和效果，而且可以为现代远程教育的理论研究和实践探索提供大量的、鲜活的依据。只有调查工具即问卷的信度在研究范围内可接受时，才能认为调查结果是客观的、科学的，也才能保证统计分析结果的可靠性和稳定性。在进行数据统计分析之前，先对问卷的信度进行分析是十分必要的。

On the Application of Creditability Analysis into the Follow-up Investigation of Graduates

The follow- up investigation of the graduates from the open learning aims to investigate, judge and evaluate the instructional quality of the open learning in terms of social recruiting employers and graduates from three measuring questionnaires. The findings not only evaluate the instructional quality and effectiveness of open distance learning scientifically and objectively, but also provide a large amount of lively basis for the theoretic research and practical exploration of the modem distance education.
