Recognizing the ethical implications of computing, leading computing organizations advise integrating ethics within traditional technical and theoretical courses. Yet, many instructors feel unprepared or unqualified to introduce ethical concepts, fail to see their relevance to technical topics, or lack the time to cover ethics without sacrificing…

This study sought to address the gap in knowledge about the effect of UDL features on asynchronous online postsecondary learners' achievement, engagement, and self-efficacy. The study also described a process for redesigning an online course to incorporate UDL components and provided specific examples of the implemented UDL guidelines. The study…

Machine learning has achieved state-of-the-art performance in many areas, including image recognition and natural language processing. However, there are still many challenges and mysteries attracting numerous researchers. This dissertation comprises a series of works concerning problems at the intersection of computer science theory, adversarial…

Computer science instructors typically have many responsibilities, such as creating material, delivering lectures, clarifying student questions, and grading student deliverables, while the demand for computer science education has been increasing. Handling all of these responsibilities is challenging in itself. However, it is made worse when…

Computing education has growing inclusion and equity challenges (e.g. exclusionary online learning experiences, biased assessments, inadequate student feedback mechanisms). Many groups experience minoritization in computing education, including students who are Black, Indigenous, and people of color (BIPOC), women, non-binary students, transfer…

As part of the process for designing an online information technology (IT) course, hands-on activities may be included; however, the literature has not readily revealed the best practices and challenges instructional designers (IDs) face with including hands-on activities in an online IT course. Research has shown that hands-on learning increases…

The purpose of this quantitative study was to determine any correlations between an increase in knowledge from activities which utilize self-paced learning, inquiry-guided learning, and collaborative learning pedagogical strategies and students' intentions to pursue science, technology, engineering, and mathematics (STEM) and computer science…

The field of computer science has long been plagued by issues of diversity - in particular, attracting and retaining those historically marginalized in computing contexts. This is a great loss to the field, to the future of innovation, and to society. Perhaps most importantly, it is an incalculable loss to those populations excluded from pursuing…

It is becoming increasingly necessary for every child to have experience with 21st century Computational Thinking (CT) skills including learning to program. Considerable efforts have been made within the last two decades including the development and widespread use of novice-friendly block-based programming environments such as Scratch and Snap!…

This research explores the difficulties faced by many migrant, refugee, and immigrant adults confronted with technological ubiquity in economically developed countries. Preparing migrant adult learners for the digital world by building digital literacy skills can help to maintain home language proficiency, support English language learning, and…

Decreasing enrollments, lower rates of student retention and changes in the learning styles of today's students are all issues that the Computer Science (CS) academic community is currently facing. As a result, CS educators are being challenged to find the right blend of technology and pedagogy for their curriculum in order to help students…

This thesis is about a design process for creating "educationally relevant" tools. I submit that the key to creating tools that are educationally relevant is to focus on ensuring a high degree of alignment between the designed tool and the broader educational context into which the tool will be integrated. The thesis presents methods and processes…

Current educational initiatives encourage the use of authentic learning environments to realistically prepare students for jobs in a constantly changing world. Many students of the Millennial generation may be social media savvy. However, what can be said about learning conditions and student readiness for active, reflective and collaborative…
