An Empirical Study on the Nature of Trick Test Questions     

Dennis M. Roberts 《Journal of Educational Measurement》1993,30(4):331-344

This study attempted to better define trick questions and see if students could differentiate between trick and not–trick questions. Phase 1 elicited definitions of trick questions so as to identify essential characteristics. Seven components were found. Phase 2 obtained ratings to see which components of trick questions were considered to be most crucial. The intention of the item constructor and the fact that the questions had multiple correct answers received highest ratings from students. Phase 3 presented a collection of statistics items, some of which were labeled on an a priori basis as being trick or not–trick. The analysis indicated that examinees were able to statistically differentiate between trick and not–trick items, but the difference compared to chance was small. Not–trick items were more successfully sorted than trick items, and trick items that were classified as intentional were sorted about as well as nonintentional items. Evidence seems to suggest that the concept of trickiness is not as clear as some test construction textbook authors suggest.  相似文献   

State-of-the-art in biomedical literature retrieval for clinical cases: a survey of the TREC 2014 CDS track

Providing access to relevant biomedical literature in a clinical setting has the potential to bridge a critical gap in evidence-based medicine. Here, our goal is specifically to provide relevant articles to clinicians to improve their decision-making in diagnosing, treating, and testing patients. To this end, the TREC 2014 Clinical Decision Support Track evaluated a system’s ability to retrieve relevant articles in one of three categories (Diagnosis, Treatment, Test) using an idealized form of a patient medical record. Over 100 submissions from over 25 participants were evaluated on 30 topics, resulting in over 37k relevance judgments. In this article, we provide an overview of the task, a survey of the information retrieval methods employed by the participants, an analysis of the results, and a discussion on the future directions for this challenging yet important task.  相似文献
