The advent of e-learning has been a welcomed development in African universities, especially in countries where the demand for university education far outstrips capacity. This form of instruction not only has helped in reducing the problem of managing and testing large classes, but it also has helped lecturers in providing valuable assistance to students who would otherwise not have such access. The limitations of the e-learning platform coupled with a distorted student-teacher ratio has raised concerns about quality, especially for traditional humanities disciplines where the emphasis on argumentative rigor and critical thinking are at odds with the scienceleaning orientation of e-learning platforms. This concern is especially important because the technology is relatively new and there are problems of access not only in terms of infrastructure but also in terms of the relevant computer literacy skills required of users of the technology. This essay examines the problems associated with the use of e-learning in teaching and examining traditional humanities courses in general but especially the problems encountered in using e-learning in teaching and assessing critical thinking courses at the University of Botswana. I argue that although certain aspects of e-learning are structured, confining, and therefore unsuitable for traditional humanities disciplines, e-learning can still be an appropriate tool for the humanities if used appropriately and creatively.
The environmental crisis that faces the world today is sometimes seen to be the result of making wrong turns on the path to human development. This is especially so in terms of the technologies humans adopt, the way such technologies are powered, and the morality that is at the foundation of societies that develop and utilize such technologies. Humanity has come to the realization that the technologies that were ushered in with a fanfare and that may still enjoy considerable patronage sometimes have a darker side that may exact a costly price. The situation would probably have been different if there had been credible alternatives waiting in the wings, but no such alternatives exist and the path to such alternative technologies will probably be fraught with even more dangers. The view in this paper is that the current environmental crisis is not so much a problem of making wrong choices in technology as it is a problem with the nature of our science: a science which stifles the growth of views that contradict the opinion at the centre. It argues that the discouragement of adventitious ideas is responsible for the lack of credible alternatives to current technologies and therefore the inability to discard technologies that are considered anachronistic. In view of the above, the paper argues for a liberalisation of science through the tolerance of heretical scientific views as well as alternative knowledge systems. It questions the morality of subscribing to a single method of science in an era where alternatives exist to every other human facility and argues, following Mill and Feyerabend, not only for the proliferation of technologies but also for the proliferation of sciences as a safeguard against scientific lethargy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
