Likert scale measures are commonly used in assessing student performance as well as student perceptions. They are particularly good in gathering data to subjective questions, but being able to compare and contrast multiple Likert data has been a challenge for the typical academic. Researchers and educators alike frequently assign a numerical value to each(More)
Most computing programs now have some form of integrative or capstone course in which students undertake a significant project under supervision. There are many different models for such courses and conducting these courses is a complex task. This report is intended to assist instructors of capstone courses, particularly those new to the model of teaching(More)
The existence of an ordinal measure already exists and is well justified, but a modest extension of the consensus formula permits Likert scale data to be assessed with respect to a predetermined value, and the results used for comparisons and trajectories. The new measure, called the strength of consensus, is a modification of both the Shannon entropy, an(More)
Complaints often expressed about undergraduate computer science or information systems programs,,, is that students graduate with adequate technical skills but often lack an understanding of organizational processes, team project experience, and the ability to integrate information technology in an organizational setting. To address this, educators have(More)
There are millions of web applications and systems developed and used today. However, the majority of them have significant usability flaws. Given the exponential growth of the web, there is a possibility of us facing a web usability crisis. In order to avoid it, significant improvements in usability of web sites are needed. Therefore, more skilled HCI(More)

Focused on an analysis of key firms in the financial services sector, the study examines in a best practices survey, confirmatory detailed case studies and statistical interpretation(More)
Many educators have campaigned to increase mathematical content in the curriculum guidelines for Information Systems. Unfortunately, mathematical concepts are often presented in a manner that conflicts with the general mental framework, or gestalt, of most IS students. But fortunately there is more than one gestalt in mathematics. This paper attempts to(More)
This paper examines a decade of our institution's use of community-based non-profit organizations (NPOs) in the information systems capstone course. Information systems or computer science majors often have technical skills but lack an adequate understanding of organizational processes, team project experience, and the ability to integrate information(More)
Object-oriented programming has become a mainstay of computing curricula over the last decade. Although its industrial promise for improving productivity, particularly by way of enabling extensive reuse, has propelled it to an essential status, it is usually taught in a vacuum of little or no effective modeling theory or practice. In this paper we argue(More)
This poster updates a paper [3] presented at ITiCSE 2006 and re-examines a ten-year effort of our institution's use of community-based non-profit organizations (NPOs) in the information systems capstone course. Computer science or information systems majors often have adequate technical skills but lack an understanding of organizational processes, team(More)
