Аннотация:In the 21st century, educators are utilising emerging technologies to develop not only knowledge of graduates, but also their soft skills in order to enhance competencies parallel with employer's requirements. Collaborative learning has been proven in promoting soft skills development. However, the feedback from employers is the opposite. It shows that collaboration does not happen naturally in a group. In previous studies, researchers have identified factors and elements needed to develop effective collaborative online learning and proposed an Online Collaborative Project based Collaborative Learning (OPBCL) model. In this study, based on OPBCL model, a prototype is designed using the ADDIE model. To carry out the study, the prototype needs to work properly. Therefore, Alpha, Beta, and User Acceptance Testing (UAT) must be conducted. This study also will show the process of testing to ensure the functionality of a prototype when running the actual study. The results are expected to show that the prototype is ready to be tested in the actual study. It is hope that this study will give much significance to other researchers regarding the importance of conducting UAT of the prototypes developed prior to the research study.
