In order to prepare students for employment as graduates they will be provided a quality assured teaching and learning environment which is conductive to the development of adult learning. Adult learning is characterised by the students accepting responsibility for their own learning and actively participating in the learning process as individuals and as contributors to the teams. Adult learning is the hallmark of a professional. The specific responsibilities as adult learners in respect of this subject are:
. to be aware of and to observe the regulations related to plagiarism
. to submit (on time) all work for assessment as required
. to complete all pre-reading and preparatory work prior to the class for which it will be used
. to effectively use the academic staff resources provided (consultation time, tutors, e- mail etc)
. to participate as an effective and honest member of a learning team
. to contribute effectively to a group of peers in a climate of mutual respect and to question each other and the academic staff when uncertain
