Investigation of factors affecting students\u27 satisfaction with online course components.

Technological advances in Internet delivery have allowed university course offerings to change from synchronous to asynchronous. These changes have occurred so rapidly that Web-based (WB) courses have proliferated without significant research as to their effectiveness from a student\u27s perspective (Ewing-Taylor, 1999). Researchers are aware that it is not sufficient to measure the effectiveness of WB learning purely through testing and grades. Indeed, Marshall (1999) pointed out that it is necessary to look at and evaluate the process of delivery and attitudes toward various delivery methods as well as course components in order to design more effective courses for Web delivery and to explore their effectiveness. Five quasi-models of descriptive characteristics (Demographic, Experiential, Motivational, Learning Styles, Instructional Design) were singled out as potentially having an impact on students\u27 satisfaction with the online course components (email, hypertext, online threaded discussions, web links, chat, video, audio, simulations, and graphics). The purpose of this study was to investigate various factors that might affect students\u27 satisfaction with online course components. Data were collected from 240 online undergraduate students using an online questionnaire. The findings of this study may lead educators to rethink the process of Instructional Design (ID). They may shift or adapt the traditional ID models and theories to accommodate the new features of online courses. At the very least, a deeper understanding about the Web as a mode of delivery in distance education and its effects on distance learning should emerge. Furthermore, the findings from this research study may strengthen our understanding of how students\u27 internal characteristics affect learning outcomes in technology-mediated online environment.

Computer assisted education : design, development and evaluation.

Thesis (M.Sc.)-University of Natal, 2001.Educational institutions throughout the world are increasingly facing classes of educationally, culturally and linguistically diverse student groups. At the same time economic constraints require these institutions to expand their student base and they are therefore looking to distance education and continuing education modules to meet these challenges. Simultaneously rapid advances in desktop computing capabilities and Internet delivered information have revived interest in Computer Assisted Education (CAE). The University of Natal is no exception to these trends; schools, departments and individual members of staff are increasingly exploring the possibility of using the University's computer infrastructure to assist in delivering quality education, maintaining current standards, and addressing the multiple needs of the students. To investigate these issues a CAE program was developed for use in the Nelson R. Mandela School of Medicine to investigate how students would make use 'of the technology, and to report on the development and evaluation processes of such a development. In doing so various lessons could be learnt which could inform the further development of such software at the University. In order to support the development of the CAE program an extensive literature survey into current educational theory was conducted. Its objectives were to explore and understand all the factors affecting the development and use of computer based systems as an educational tool. Particular aspects considered were • the debate between constructivist and instructivist theory in their applicability to both the medium and the subject material. • instructional styles, and with them the learning styles, that could be used to support the educational goals of the diverse student population. • instructional design methodologies that are currently used as well as media production methodologies. The goal of this aspect of the research was to advise both the development of the case study and to gain a broader understanding of the methodology that could be used for other developments. Included in this phase of the research are methods and criteria for selection of authoring systems and interface design issues in a multi-cultural multi-lingual environment. • the review of different evaluation strategies in order to incorporate appropriate evaluation in the CAE case study. • the investigation of broader sociological and historical factors that may influence the way in which CAE can be used effectively in a South African context. The presumption was that students from historically disadvantaged backgrounds and those with English as a second language would be less willing to use technological interventions than those who were more likely to have had access to computers earlier in their education. The case study set out to investigate if this presumption was valid, and if so what elements of design and delivery could facilitate these students' usage of such systems. However, these presumptions were not validated by the case study, showing the exact opposite of expectations, with more historically disadvantaged students showing a willingness to use the module
