在介绍并评价当前主要检索行为实验方法的基础上,引入美国Marvin Zelen教授的Zelen设计,综合已有检索行为实验方法的优缺点给出应用于网络用户信息检索行为实验的改进Zelen实验设计方案。最后,文章从实验对无关变量控制的规范化评价、实验方法的规范化评价、实验内在效度评价和实验外在效度评价4个方面对这一实验方案进行了评估。
On the basis of introducing and evaluating the current experimental methods of the main retrieval behavior, this paper introduces the Zelen design of Professor Marvin Zelen in the United States, and combines the advantages and disadvantages of the existing retrieval behavior experiment methods to give an improved Zelen experimental design which is applied to the experiment of information retrieval of network users. Finally, the article evaluates the experimental scheme from four aspects: standardized evaluation of uncontrolled variable control, standardized evaluation of experimental methods, evaluation of experimental internal validity and evaluation of experimental external validity.
