In today’s age of digital transformation, e-learning, as a new paradigm of distance education, has become increasingly popular and, at the same time, has created the opportunity to facilitate the delivery of useful information to relevant audiences. The article at hand presents the CONTESSA Online Modules Courseware (COMC) as an example of an e-learning course which seeks to provide this delivery of information to its relevant audience, namely twenty-first century, student-centered teaching and learning principles to pre- and in-service teachers in Cambodia and Sri Lanka.

Besides introducing the COMC’s design, storyboard development, and the development of the courseware prototype, the results of the testing phase of this course are presented in this article. Based on the usability evaluation methods for e-learning created by (Zaharias & Poylymenakou, International Journal of Human–Computer Interaction, 25:75–98, 2009), the available testing results offer insights into the capabilities as well as deficiencies of the COMC and subsequently allow for a further advancement of the COMC.
