A series of trials to test the usability and potential impact of 4D construction learning environment have been undertaken at all partner institutions. The trials employed a range of individually devised, problem-based, learning activities which were incorporated into existing courses. Students of four construction related disciplines - architecture, construction management, building surveying and civil engineering - took part in the trials. The courses hosting trial activities ranged in study level and, in two cases, included distance learners in the cohort. The case authors report on their trial learning activity and, taking account of the feedback from their students, reflect on the usability and potential impact of the application in teaching and learning practice.

Student feedback was collected through an anonymous five-question post-trial survey form. At UoN and UniSA, course participants responded to an online version of the questionnaire. At UQ a paper version of the questionnaire was distributed at course tutorials. Ethics approval was sought and received from The University of Queensland, Behavioural & Social Sciences Ethical Review Committee, Approval No 2015000324; The University of Newcastle, Human Research Ethics Committee Reference No H-2015-0089; and, University of South Australia, Human Research Ethics Committee Reference No 0000034368.
