STEMPS Theses & Dissertations

Calling upon principles of positive psychology, the quantitative study used structural equation modeling (SEM) to explore the relationships between teacher psychological capital (PsyCap), role ambiguity, role conflict, role overload, workplace stress, job satisfaction, job commitment, and intention to quit. Valid and reliable instruments from the literature were incorporated into a 64-item survey and distributed to 830 third through fifth grade teachers at seven northern Virginia school districts. In total, 225 complete responses were received. SEM testing rejected the exact-fit hypotheses and revealed insufficient overall fit between the study data and hypothesized models; thereby, providing no support for the proposed causal …

STEMPS Theses & Dissertations

This study determined the influence of the learner factors on Soldier attitudes toward the use of serious gaming for U.S. Army training and leader development. It extended Selwyn's work (Selwyn, 1997a, 1997b, 2003, 2004, 2006, 2013; Selwyn, Gorard, Furlong, & Madden, 2003) identifying or measuring attitude toward using a technology and Bonanno and Kommers (2008) work extending Selwyn's work to measure the influence of learner factors on those attitude components toward the use of Army serious gaming for instructional purposes. The population studied was 709 Active duty U.S. Army Soldiers.

This quantitative non-experimental descriptive research design methodology used a 21-item …
