The thesis investigated the use of combination of sections using learning steps in the development of courseware presentation in the 3D Virtual Worlds platform. The technical objective of the study is to present the design of multisection strategy in developing healthcare course in 3D Virtual World online environment. The main aim of this study is to know the effects of multisection [objective, tutorial (with or without video), quiz and test] sections incorporation in an online 3D Virtual World towards the usability. The empirical research described in this thesis comprised three experimental phases. In the first phase, an initial experiment was carried out with 21 users to explore the usability and learning performance of courseware created using 3D the Virtual World platform of Second Life. The second experiment phase involved an experiment conducted with 30 users to investigate their perception, satisfaction and performance of the role of each main section involved in Virtual World courseware. In the third phase, a total of 30 users experimentally examined a unique approach to the use of video segment added in the Tutorial section of the OTQT framework. The overall obtained results demonstrated the usefulness of the tested multisection to enhance the development of healthcare course in an online learning of 3D Virtual World program. These results in three experiments provided a set of unique and empirically derived guidelines for the design and the use of three multisection frameworks to generate more usable courseware in the 3D Virtual Worlds of an online learning interface. For example, when designing avatars as animated virtual lecturers in e-learning interfaces, specific facial expression and body gestures should be incorporated due to its positive influence in enhancing learners' attitude towards the learning process.
