In computerized adaptive testing (CAT), aberrant responses such as careless errors and lucky guesses may cause significant ability estimation biases in the dynamic administration of test items. We investigated the robustness of the 4-parameter logistic item response theory (4PL IRT;
Barton & Lord, 1981) model in comparison with the 3-parameter logistic (3PL) IRT model (Birnbaum, 1968). We applied additional precision and efficiency measures to evaluate the 4PL IRT model. We measured the precision of CAT with respect to the estimation bias and mean absolute differences
(MAD) between estimated and actual abilities. An improvement in administrative efficiency is reflected in fewer items being required for satisfying the stopping rule. Our results indicate that the 4PL IRT model provides a more efficient and robust ability estimation than the 3PL model.
Purpose
This paper aims to illustrate how mobile devices could be applied to substantiate cognitive apprenticeship model to optimize nursing students’ learning experiences in clinical settings.
Design/methodology/approach
Eight female students from a nursing college in Taiwan were recruited in this study. They enrolled in a three-week nursing clinical practicum session in the area of psychiatric nursing.
Findings
Analysis of interview data from students and instructor showed that use of the mobile technology could promote the effectiveness of cognitive apprenticeship model, especially for processes of reflection, coaching, scaffolding and articulation.
Originality/value
The present study intended to bridge the gap between mobile technologies and cognitive apprenticeship. This study explores students’ experiences and expectations of using mobile technology in clinical nursing courses and clarifies how the cognitive apprenticeship model fits students’ experiences during using mobile technology in the clinical nursing course.
This article reports on the implementation of a web-based video-annotation system that supports online peer-assessment activities in a nursing communication training scenario. A quasi-experimental design was applied to investigate the effects of using video annotation on communication skills and professional attitudes. The participants were fourth-year students from two classes at a nursing college in Taiwan. One class of 50 students served as the experimental group, who used the video-annotation tool we designed to add their comments to videos. The other class of 50 students served as the control group and used YouTube to add comments. Although YouTube also provides video-annotation features, these are not often used. Two rounds of peer-assessment activities indicated that the video-annotation tool notably enhanced nursing students’ communication performance. Specifically, the tool was helpful in promoting students’ development of communication skills, but not their professional attitudes. The students using the video-annotation tool provided more suggestions in their peer comments than those who did not use it. Moreover, video annotation resulted in closer agreement between peer and expert ratings of students’ communication. The use of a video-annotation feature could improve the effectiveness of online peer assessment and thus promote student performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
