ABSTRACT
Enthusiastic educators digitize different sorts of learning materials in the hope of enhancing learning outcome. The learning outcomes from this trend, however, remain inconclusive because detailed evaluation is often lacking. One difference between the traditional printed medium and the digital medium is the arrangement of presentation of the concepts to be learnt. Digital medium allows the concepts to be arranged in a networked structure with the aid of hyperlinks which is not possible in traditional printed medium. The digital medium may therefore complement the strengths of problem-based learning pedagogy, as they share the same objective in encouraging the learners to explore. To assess the interaction effects of problem-based learning and digital medium, techniques in learning outcomes assessment were further explored. A group of research postgraduate students with biological psychology background was asked to make pair-wise difference comparisons on some biological psychology terms, which constitute the dissimilarity matrices.
