Trials of the AEB 4D Construction Learning Environment have begun at project partner institutes, UniSA and UoN. A further set of trials at UQ and UoN will take place in Semester 2. Student and academic staff evaluation of the 4D digital application and associated problem-based learning activities will follow each trial. Evaluation data will inform further developments of the 4D application, particularly in terms of usability, as well as providing initial insights into the potential for wider educational impact.
