The advent of new technologies has always spurred pedagogical innovations, whether it be the blackboard, the overhead projector or, today, the internet. Each innovation opens up new opportunities for teaching and learning while resolving challenges that started to build up during the previous technology eras.
Currently, post-school education and training (PSET) institutions face an array of challenges, including the need to increase student access to quality education, the rising costs associated with providing full-time education, and diminishing faculty resources relative to growth in student numbers. Essentially, PSET institutions need to be able to educate more students in a way that is financially sustainable for both them and their students.
