Wayne State University Dissertations

The purpose of this study was to examine the psychometric properties of the Michigan School Libraries for the 21st Century Measurement Benchmarks (SL21). The instrument consists of 19 items with three subscales: Building the 21st Century Learning Environment Subscale, Teaching for 21st Century Learning Subscale, and Leading the Way to 21st Century Learning Subscale. The sample consisted of 54 respondents who were administered the instrument in 2014 and 2015. Cronbach’s alpha for the total instrument was 0.807 (n = 19 items). Exploratory factor analysis (EFA) was used to measure construct validity. The findings derived from the EFA did not tend …

The Reliability and Validity of the Thin Slice Technique: Observational Research on Video Recorded Medical Interactions

Introduction: Observational research using the thin slice technique has been routinely incorporated in observational research methods, however there is limited evidence supporting use of this technique compared to full interaction coding. The purpose of this study was to determine if this technique could be reliability coded, if ratings are consistent between the first, second and third slice, and if they are indeed representative of full interactions.

Methods: Three 30-second thin slices were sampled from the beginning, middle and end of a full-length video-recorded …

In the state of West Virginia, the educator evaluation system was implemented in 2010 as part of a comprehensive system of support to increase teacher effectiveness and student learning. As part of the system, the Educator Evaluation Instrument was developed to measure teachers' effectiveness. This study was conducted to determine whether the Educator Evaluation Instrument was valid for use in measuring effectiveness.

A hierarchical confirmatory factor analysis (HCFA) was conducted on the scores from the demonstration year. The data were not normal, nor was good model fit established based on the current model. Because good model fit could not be …
