Learner perceptions on instructional design of multimedia in learning abstract concepts in science at a distance

This study was carried out to explore learner perceptions on the instructional design features of interactive multimedia (IMM), which was especially designed to support the open and distance learners studying microbiology as a part of the BSc degree programme of the Open University of Sri Lanka (OUSL). The purpose of developing this IMM was to explain the dynamic abstract concepts and processes of bacterial genetics that are hard to comprehend by referring to print course material, as surfaced from course evaluations. When developing the IMM package, emphasis was placed on the interface design, navigational design and instructional design in particular. Instructional design was mainly based on Gagne’s nine events of instructions, and Mayer’s Cognitive Theory of Multimedia Learning on verbal and pictorial information. IMM was designed incorporating basic instructional features such as learning outcomes, an introduction, self‐assessment questions, glossary, and so forth. Animations with narrations were exte...
