This paper presents an improved Distributed Genetic Algorithm (DGA) that surpasses the classic genetic algorithm (GA) in terms of both efficiency and effectiveness when it comes to optimizing faculty scheduling systems. The proposed Differential Evolution Genetic Algorithm (DGA) combines DE with chaotic mapping and asynchronous communication to…

Recently, audio-visual feedback produced through screencast technology has received increasing attention. Yet, as opposed to synchronous (immediate) and bi-directional (a two-way process) audio-visual feedback, most recent research has focused on asynchronous (delayed) and unidirectional (a one-way process) audio-visual feedback. Therefore, this…

This quantitative study used a web-based questionnaire to assess the attitudes and perceptions of online and hybrid faculty towards student-centered asynchronous virtual teamwork (AVT) using the technology acceptance model (TAM) of Davis (1989). AVT is online student participation in a team approach to problem-solving culminating in a written…

In the last decade, we have seen the emergence of virtual learning environments. Initially, these environments were a little more than document repositories that tutor used unicast to the students. Informed in part by social constructivist theories of education, later environments included capabilities for tutor-student and student-student,…

Background: In the 1990s, Salmon developed a five-stage model for enabling and scaffolding remote groups to work and learn together using asynchronous bulletin boards. The model has informed online learning and development practice across different levels and education for online and blended learning. Purpose: This paper reports our testing of the…

This paper explores the feasibility of using a blended approach to postgraduate research-degree supervision. Such a model could reduce research supervisors' workloads and improve the quality and success of Masters and Doctoral students' research output. The paper presents a case study that is based on a framework that was originally designed for…

This paper discusses a university-wide pilot designed to encourage academics to creatively explore learner-centred applications for digital audio. Participation in the pilot was diverse in terms of technical competence, confidence and contextual requirements and there was little prior experience of working with digital audio. Many innovative…

The reasons that the current tutorial system (CTS) does not produce significant effects include the budgets and policies of schools, the greater independence of students, and the infrequent interaction of tutors with students. To reduce the deficiencies of the current tutorial system, this paper proposes a network tutorial system (NTS) and…
