This study aims to assess how learners apply visual design principles into hypermedia they developed in groups in a constructivist learning environment where they use such hypermedia as a cognitive tool. The study design includes a total of 30 second-year university students who enrolled on an Instructional Technology and Material Preparation course at Middle East Technical University, and which lasted 14 weeks. The data were collected using a Visual Design Principles Evaluation Checklist. The results of the study indicate that the majority of the students applied visual design principles effectively on these hypermedia-based instructional material.
