The Bachelor of Engineering (Co-op) has been offered at CQUniversity, Australia, since 1994. Development of the co-operative education program recognised that real learning from the work placements would require explicit preparation for the work placement, and reflective practice after the placement. The outcome would be the ability of the students to articulate their learning, and recognise their strengths and weaknesses at any stage in the program of study. Following the introduction of the co-op program, the faculty instituted a staged introduction of activities and processes to achieve the preparation and reflection requirements for the work placement. The changes included a move to Project Based Learning (PBL) with a partially inverted curriculum, and the introduction of a dual award, the Bachelor of Engineering (Coop)/Diploma of Professional Practice. PBL and an inverted curriculum was introduced in 1998, with the aim being to ensure that students were sufficiently prepared to work as junior engineers in industry at the end of their second year of study. The PBL curriculum was intended to teach students in context, with content being integrated instead of delivered in discipline silos, as well as developing a number of the professional practice skills required, such as teamwork, communication, critical thinking and problem solving.The Diploma of Professional Practice was introduced in 2004 to make explicit the preparation for and reflection on the workplace experience. Many of the activities and outcomes addressed by the new Diploma program had been delivered by the faculty prior to this time, but the students had not been given credit, and the faculty had received no payment for the extra work. This paper describes the programs and justifies the decisions made to offer these programs in this format.
