Design and Evaluation of POSbase: A Web-Based Learning Environment
MetadataShow full item record
This dissertation presents the design, development and evaluation of POSbase in psychology learning. POSbase (Presentation Of Science base) is an online collection of scientific experiments and related information. This is a flexible system that encourages constructive and self-regulated learning by exploring information of interest. It also allows researchers and instructors to share their teaching materials and experiences. The goal for this study was to discover new design challenges through a formative evaluation. POSbase was therefore introduced to students at the Department of Psychosocial Science. We conducted two evaluations and implemented improvements in between. From the evaluations we found that the students were quite positive toward POSbase, but we also found several design challenges to guide the further development. The research contribution of this thesis is the design challenges found from the evaluations and the discussion of these.
