Digital Scholarship of Teaching: Research Methodologies

Content Validity indicates how much a test represents all the items from the universe which it is drawn (Salkind, 2016). This is usually established with expert opinion (Salkind, 2016). 

Construct Validity is the extent to which test results are related to an underlying set of variables (Salkind, 2016).  This is how we can determine the extent to which  a speed test actually measures speed or a comprehension test actually measures comprehension.

Study: Zhang, H., Goh, S. H. L., Wu, X. V., Wang, W., & Mörelius, E. (2019). Prelicensure nursing students' perspectives on video-assisted debriefing following high fidelity simulation: A qualitative study. Nurse education today, 79, 1-7.

The point of this study was to do qualitative research on pre-licensure nursing students’ experiences with Video-assisted Debriefing (VAD) following a high-fidelity stimulation (Zhang et al., 2019). There is a fair amount of evidence that suggests that VAD is beneficial however there is a lack of research on students’ attitudes as it pertains to VAD (Zhang et al., 2019). The researcher asserts that it is important to know the perspectives and attitudes of the learners’ involvement with VAD for effective learning (Zhang et al., 2019). The study found that nursing students thought the VAD worked well with the verbal debriefing and improved their attitudes and behaviors through the simulation (Zhang et al., 2019). Ultimately the study proof that VAD enhanced the awareness, attitudes, and behaviors of the nursing students through the simulation however since research on this phenomenon is sparse further research is necessary to explain why (Zhang et al., 2019). The implication of this study is that VAD is beneficial for simulation-based learning especially when students are familiarized with the fact that they will be observed to mitigate their anxiety.
