The author has attended and presented at most ASCUE meetings since 1994, and has worked professionally in research and development, industry, military, government, business, and private and public academia--moving between computer science, software engineering, and business fields at both the undergraduate and graduate level, and even running…

The concept of flipping the classroom is slowly gaining tractions at all levels of education. An ever-growing set of resources gives unprecedented access to Information Technology (IT), Computer Science (CS), and Information Systems (IS) students to a significant amount of supplemental material. Videos, interactive demonstrations, and sandboxes…

Bitcoin, Litecoin, Dogecoin, et al "cryptocurrencies" have enjoyed a meteoric rise in popularity and use as a way of performing transactions on the Internet and beyond. While gaining market valuations of billions of dollars and generating much popular press in doing so, little has been academically published on the Computer…

Within existing ICT degrees there is a widely-held belief that content must be tailored for different "kinds" of students--often two differing student groups: a technical group requiring detailed Computer Science knowledge and a separate group requiring less technical, more strategic ICT knowledge and skills. Our institution has produced…

The increasing popularity of high-bandwidth Internet connections has enabled new applications like the online delivery of high-quality audio and video content. Conventional server-client approaches place the entire burden of delivery on the content provider's server, making these services expensive to provide. A peer-to-peer approach allows end…

This paper describes a framework for measuring student learning gains and engagement in a Computer Science 1 (CS 1) / Information Systems 1 (IS 1) course. The framework is designed for a CS1/IS1 course as it has been traditionally taught over the years as well as when it is taught using a new pedagogical approach with Web services. It enables the…

As punishment in the biblical story of Moses the slaves were told they had to make bricks without straw. This was impossible because bricks made without straw had the appearance of strength and function but could not withstand the proof of actual use. The slaves' punishment was therefore not only to make bricks, but also to find the straw on their…

Traditional information systems return answers after a user submits a complete query. Users often feel "left in the dark" when they have limited knowledge about the underlying data, and have to use a try-and-see approach for finding information. The trend of supporting autocomplete in these systems is a first step towards solving this problem. A…

The purpose of this dissertation is to explore and analyze a domain of research thought to be shared by two areas of philosophy: computational and digital ontology. Computational ontology is philosophy used to develop information systems also called computational ontologies. Digital ontology is philosophy dealing with our understanding of Being…

The nation's critical infrastructure, information systems, and telecommunication networks are vulnerable and threatened by an ever-growing number of attacks in cyberspace. An essential element of the nation's comprehensive approach to cybersecurity is the ability for the Department of Defense to protect and defend its information enterprise.…

The demand for graduates with exposure in Cloud Computing is on the rise. For many educational institutions, the challenge is to decide on how to incorporate appropriate cloud-based technologies into their curricula. In this paper, we describe our design and experiences of integrating Cloud Computing components into seven third/fourth-year…

Using a previously published study of how students differentiate between computing disciplines, this study attempts to validate the original research and add additional hypotheses regarding the type of institution that the student resides. Using the identical survey instrument from the original study, students in smaller colleges and in different…

Identification and access management has been among the top security issues facing institutions of higher education. Most institutions of higher education require end users to provide usernames and passwords to gain access to personally identifiable information (PII). This leaves universities vulnerable to unauthorized access and unauthorized…

The interactional feature of hypermedia that allows high-level student-control is considered as one of the most important advantages that hypermedia provides for learning and teaching. However, high-level student control in hypermedia might not always lead to high-level learning performance. The learner is likely to experience navigation problems…

Understanding the potential or need for ICT support in education within developing countries, requires an in-depth needs assessment to comprehend, elaborate and set the desired priorities of rural schools. A Needs Assessment was conducted as part of an on-going comprehensive evaluation process of an ICT for development project, the Siyakhula…
