Many organizations are providing employee training to raise security awareness as data breaches increase. Organizational digital transformation has accelerated, especially during the COVID-19 outbreak. It has made the technology industry a prime target for cyberattacks. Although more organizations invest in cybersecurity training, data breaches…

This study explored correlations between Virginia K-8 teachers' confidence in computer science (CS) teaching and their confidence in technology teaching using a quantitative, nonexperimental, explanatory research design. Two constructs of the Teacher Efficacy and Attitudes Toward STEM Survey (Friday Institute for Educational Innovation, 2012b)…

Jung and Won's (2018) review of elementary school ER found a lack of understanding of instructional practices for ER with young children. Other researchers have called for further studies into what effective classroom orchestration and interaction look like within ER classrooms (Ioannou & Makridou, 2018; Xia & Zhong, 2019). This study was…

This dissertation investigates the application of network models in educational assessment across diverse learning settings, encompassing both clinical and classroom environments. As educational paradigms shift and digital tools become more embedded in learning processes, traditional assessment methods often fall short in effectively capturing the…

The problem of low student completion rates in distance learning courses remains one of the major issues that institutions of higher learning face. Efforts by school administrators to reverse this trend have so far produced mixed results. The rapid expansion of distance learning has encouraged many institutions to move more courses online,…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

Piaget's classic work on cognitive development showed that engaging learners in critical discussions with peers about ideas that are "different" than theirs leads to deep conceptual understanding. Implementing such an approach in college-level STEM (Science, Technology, Engineering, Math) courses has some specific challenges: (a) Short…

The purpose of this study was to determine a student's computer knowledge upon course entry and if there was a difference in college students' improvement scores as measured by the difference in pretest and posttest scores of new or novice users, moderate users, and expert users at the end of a college-level introductory computing class. This…

In this educational study, the research problem was that each semester a variable number of community college students are unable to complete an introductory computer applications course at a community college in the state of Mississippi with a successful course letter grade. Course failure, or non-success, at the collegiate level is a negative…

Purpose: The purpose of this study was to examine differences between boys and girls in their performance on STEM related AP exams. Specifically, gender differences were examined for the following STEM related AP exams: Calculus AB, Calculus BC, Physics B, Physics C: Electricity and Magnetism, Physics C: Mechanics, Chemistry, and Computer Science…

The purpose of this quasi-experimental static-group comparison study was to test the theory of transactional distance that relates the inclusion of synchronous class sessions into an online introductory computer course to students' levels of satisfaction and academic achievement at a post-secondary technical college. This study specifically looked…

Teaching computer programming to freshmen students in Computer Sciences and other Information Technology areas has been identified as a complex activity. Different approaches have been studied looking for the best one that could help to improve this teaching process. A proposed approach was implemented which is based in the language immersion…

A reexamination of the traditional instruction of introductory computer science (CS) courses is becoming a necessity. Introductory CS courses tend to have high attrition rates and low success rates. In many universities, the CS department suffered from low enrollment for several years compared to other majors. Multiple studies have linked these…
