Abstract:
Extant literature indicates that web-based blended learning will become the most accepted mode of delivery in the near future as an alternative to traditional face-to-face instruction particularly in the higher education landscape due to its potential to provide increased access to education for more people, increased student engagement with the tutor, rich learning resources, peers, and external experts, and flexibility beyond the limits of classrooms without compromising quality. The study focused on developing a web-based blended learning model that could help reap the benefits of blended learning at the University of Botswana (UB).
With this in mind, the research question, "How can a web-based blended learning environment be designed, developed and implemented at the University of Botswana?" was formulated.
In order to address the research question, a six-dimensional model called LAPTEL was developed. The six dimentions are: Digital Leadership, Equitable Access, Active Participation, Authentic Tasks, Intellectual Engagement and Learning (LAPTEL); the first five dimentions are requisites to enable studnets to progress towards successful learning which is the sixth dimension.
The LAPTEL model depicts guidelines on how to ensure equitable access for students to learning contexts, motivate and enable them to participate in meaningful educational processes, design and develop effective online as well as classroom learning materials (tasks), and engage students in active 'communityes of practice' in order to help them construct their own knowledge (learning) collaboratively under proper leadership. The Researcher considers it essential to have a complex interplay between the three components - active participation, authentic tasks and intellectual engagement to facilitate active, non-linear learning, and it will be catered for in the design, development and delivery of courses based on the LAPTEL model. The fact that these three dimensions have got features of both face-to-face and onlilne learning, integrated seamlessly, makes the LAPTEL a Web-based learning model. The overall aim was to develop a model of curriculum (re)design based on the student-centred pedagogical approaches that combine synergistically the effectiveness of traditional classroomwith technologically enhanced socialization and active learning oppotunities of the online environment in order to support student learning more effectively than what is possible in a typical lecture room.
In a case study to evaluate the effectiveness of the LAPTEL model in the context of UB, the Researcher found that it could provide students with opportunity for increased interactive engagement (more than that is normally possible in 'face-to-face-only' or 'online-only' environments), flexibility and cognitive scaffolding that enhanced their learning experience. The Researcher concludes that the LAPTEL model fits well in the UB context, and it may be adopted by other institutions working under similar contexts.
