This dissertation presents a novel theory of event memory along with an associated computational model that embodies the claims of view which is integrated within a cognitive architecture. Event memory is a general-purpose storage for personal past experience. Literature on event memory reveals that people can remember events by both the…

This dissertation describes an experiment to investigate how learners with different levels of background in computer science learn core concepts of computer science, in particular, algorithms. We designed a study to focus on cognitive task analysis for eliciting the empirical mental elements of learning two graph algorithms. Cognitive workload…

This convergent parallel mixed methods study with qualitative and quantitative content analysis was conducted to analyze and describe the cognitive complexity of the publicly released Advanced Placement Computer Science Principles Exam questions compared to the language of higher-order thinking found in research literature. Hess' Cognitive Rigor…

There is growing consensus that data-informed decision-making through human-centered inquiry and design process results in improved outcomes for designed artifacts. Among the latest trends is a group of tools and processes loosely assimilated under the umbrella term, "design thinking." These "designerly ways of knowing" are…

This dissertation aimed to expand knowledge and practical uses of educational technology tools in high-stakes team training environments. This study depicted the real-world impacts of virtual reality (VR) technology on learning and training for the Royal New Zealand Police Academy and those training teams in high-stakes environments.…

Human space exploration is entering a new era through the design of missions that venture further from earth for longer durations, such as missions to the Moon and Mars. Mission success during long duration exploration missions (LDEM) requires astronauts to flawlessly execute exceptionally complex skills across a multitude of tasks, presenting new…

The goal of this qualitative study was to answer the question: How do educators make sense of learning in virtual reality? This study utilized multimedia learning theory and cognitive load theory to explore how educators understand virtual reality in education. Pre- and post-interviews as well as a VR experience were conducted with 13 educators…

This study explores the relationship between perceived authenticity and cognitive engagement within authentic learning environments, a topic that has garnered increasing attention in educational research and practice. While previous studies have linked authenticity and engagement to improved academic outcomes, there remains a gap in understanding…

A high-quality, foundational education offers lifelong benefits for young children. The problem is that working memory in pre-school-aged children is declining and could be impaired by the extraneous cognitive load imposed during engagement with screen media apps and/or preschool programs. Although the pedagogical practices associated with…

As higher education institutions go online to reap the benefits of technology and align their programs with a world economy that is increasingly becoming digital, the multimedia learning theory warns of possible challenges. Large device screens have been used to present related information elements of a learning task simultaneously to facilitate…

Recent research shows that deaf signers show increased behavioral and neural sensitivity to certain types of movement, such as biological motion, human actions, and signing avatars. However, other work suggests that in deaf signers exposed to signed language before age five, the mirror mechanism has minimal involvement during the perception of…

As online programs grow, so should attempts to create a better virtual asynchronous learning experience. The purpose of this study was to examine the impact of video-based online learning activities in increasing components of social, teaching, and cognitive presence, among interprofessional healthcare students of various age groups. Studying this…

Cognitive load is the effort needed to process and store information in memory and can be measured via subjective, physiological, and performance methods. Virtual reality learning environments (VRLEs) enhance science aptitude and motivate students to pursue science careers. Cognitive load is divided into three types: intrinsic, extraneous, and…

Embodied cognition posits that physical interactions with the environment play a crucial role in learning, including complex, abstract concepts in STEM disciplines. This is relevant for deaf and hard-of-hearing (DHH) learners who often utilize sign language, which is a naturally embodied, visuospatial mode of communication. My dissertation…

The purpose of this comparative, longitudinal case study was to explore the distance operations system implemented in U.S. colleges and universities during the COVID-19 pandemic. Embedded in a larger two-year study of distance education in the U.S. before and after the health crisis, this study combined a grounded theory methodology with a…
