    A systemic model for evaluating online course design : a critical realist approach
    (IATED, 2024-03) Reddy, Pregalathan; Pratt, Deidre
    At the Durban University of Technology (DUT), the fall-out from the recommendation by the Rapid Response Task Team to transition from the blended mode of teaching to pure online due to the lockdown caused by COVID-19 in 2020 is now being felt. The realisation is dawning that not all courses are created equally and, more damning, that some assessment practices are not as good as others. To remedy this deficit, DUT is currently running an “Assuring the Integrity of Assessment Practices Project”, under the ambit of the Centre for Quality Promotion and Assurance (CQPA). The focus is on evaluating selected online courses. As a possible option for evaluation, this paper proposes a systemic model for evaluating online courses, whether delivered in mixed mode or completely online. The research approach used to develop the model is critical realist, based mainly on Roy Bhaskar’s philosophy, but also includes Margaret Archer’s morphogenetic theory, which shows how principles developed in previous temporal epochs are not always in phase with elements of present-day contexts. This is particularly relevant in the post pandemic era, where it has been observed that student grades which were skewed upward during the COVID-19 period are now plateauing in line with the period before COVID-19. While it is obvious that certain key course elements are now no longer available to both staff and students, a systemic model of course design is needed which distinguishes between the givens and the variables, so that the most urgent course deficits are identified and remedied or replaced. It will be argued that the systemic model of course design discussed in this paper provides insight into the nature of hypermedia communication. It might assist educators to distinguish between Internet communication and written (i.e., hard print) communication by showing how the functions thought essential for learning to take place effectively are carried out in different ways and with different effects in the different media. The model in fact provides a course design principle outlining ‘felicity conditions’ for effective course delivery. However, while it suggests the prerequisites for effective course design, the ultimate assessment of effectiveness is left up to the participants – teacher and students - to decide. As the design principle used is descriptive rather than value-laden, and can thus be adapted to suit the specific local values operating in any given learning context, it is well-suited for use in multicultural educational contexts. However, it must be noted that the model is work-in-progress, and may still be refined further in both research and use.

    A learning object repository for computer assisted language learning in order to provide resources for language learners in schools in KwaZulu-Natal
    (2014) Reddy, Pregalathan; Pratt, Deirdre Denise
    This study, carried out within a critical realist orientation, offers a digital approach to providing language learning resources to learners in KwaZulu-Natal by developing a language learning object repository (LLOR). The purpose of designing and setting up a LLOR prototype was to find a way to augment and supplement the resources provided by text books, the provision of which has hitherto been fraught with service delivery problems. Margaret Archer’s substantive theory of morphogenesis was used to provide a social science framework within Bhaskar’s critical realist meta-approach. The morphogenetic approach suggests that, for technological advances to be accepted as part of everyday educational practice, they must be included in the fabric of the existing social structures of teaching and learning. This had implications for the human computer interaction (HCI) aspects of the artefact, which was developed by both anticipating user needs at the outset and confirming these at intervals; it also looked at the development of digital resources over a period of time in terms of the artefact being part of a larger movement towards using digital resources. The iterative design of the LLOR followed a series of piloting different application stacks, including MediaWiki, TikiWiki CMS and Joomla. Moodle was chosen as the most suitable application as it facilitates the sharing of content using the Sharable Content Object Reference Model (SCORM) and can also easily be packaged in an offline self-contained pack for distribution to users who have limited Internet access. Three user groups, comprising experts (those who are proficient with web and computer technologies), teachers (a representative group of teachers who were second language teachers of English) and a representative from the Department of Basic Education (DOBE), were asked to test-drive the LLOR and respond to questions about its ease of use and potential. The LLOR was primarily intended for teachers although it supports students as well. The use of a user-contributed model in the design of the LLOR anticipates i the challenge of providing direct support (editorial), as in adding new resources by only the researcher and also accepting that consumers are more likely to support user-contributed models, if they are also contributors. The key to facilitating access to resources like the LLOR is to make them accessible through different devices especially mobile platforms such as (cell-phones and tablets); future development will prioritise a mobile ready version of the LLOR. The value of the research is thought to lie in furthering an innovative mode of teaching in a digital medium setting where educational communication achieves virtual mode in and out of the physical classroom.
