Reliability And Validity Of An Arabic Version Of The Self-Determination Assessment – Internet (Sda-I), Mona Alamri Alamri

Wayne State University Dissertations

Self-determination is related to the desirable transition outcomes of an individual. It has gained an increasing amount of attention in numerous fields, including education, sociology, psychology, and other fields related to human behavior. However, there are no measures originally written in Arabic that accurately measure an individual’s self-determination. Thus, during this study, an Arabic version of the Self-Determination Assessment – Internet (SDAi) was developed from the regular English version of the assessment. The SDAi measures the cognitive, emotional, and behavioral factors related to self-determination. The purpose of this study was to develop and then test the reliability and validity of …

Reliability And Validity Of Michigan School Libraries For The 21st Century Measurement Benchmarks, Natosha Nicole Floyd

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 Effects Of Various High School Scheduling Models On Student Achievement In Michigan, Russell Edward Pickell

Wayne State University Dissertations

This study reviews research and data to determine whether student achievement is affected by the high school scheduling model, and whether changes in scheduling models result in statistically significant changes in student achievement, as measured by the ACT Composite, ACT English Language Arts, and ACT Math scores. The high school scheduling models included in this study are: six period semester (SPS), five period trimester (FPT), seven period semester (VPS), standard 4x4 block (SB), and alternate day block (ADB). Supportive and non-supportive research are discussed in regard to the impact of the student scheduling model on student achievement.

Robustness And Comparative Power Of Welch-Aspin, Alexander-Govern And Yuen Tests Under Non-Normality And Variance Heteroscedasticity, Ayed A. Almoied

Wayne State University Dissertations

Classical statistical tests are used in many disciplines such as education and psychology. Such tests are based on certain assumptions (e.g., normality and homoscedasticity) that are must to be met in order to produce accurate results. Violation of such assumptions is a common problem researchers encounter, particularly when analyzing real data. When such assumptions are violated, the effectiveness and efficiency of tests to control over the probability of a Type I error and maintain a relatively level of statistical power will be substantially affected.

Alternative modern and robust statistical tests such as Yuen test for trimmed means and the Alexander-Govern …
