Student Workload Students should note that UOW policy equates 1 credit point with 2 hours of study per week, including lectures and tutorials/workshops/practicals, self-directed study and work on assessment tasks. For example, in a 6 credit point subject, a total of 12 hours of study per week is expected.

Subject Changes and Response to Student Feedback The School is committed to continual improvement in teaching and learning and takes into consideration student feedback from many sources. These sources include direct student feedback to tutors and lecturers, feedback through Student Services and the Faculty Central, and responses to the Subject Evaluation Surveys. This information is also used to inform comprehensive reviews of subjects and courses.  Weekly lectures will have in-class quizzes to encourage active participation by students.  The weekly workshops assessments will have both formative and summative quizzes and students must work in pairs. The workshop demonstrator will rotate pairs each week. The bi-weekly formative assessment will be peer-assessed. The bi-weekly summative assessment will be individual submissions and will be marked by the workshop demonstrator. Note: Past students have identified their support of the formative quizzes as a good learning activity. Extraordinary Changes to the Subject Outline In extraordinary circumstances the provisions stipulated in this Subject Outline may require amendment after the Subject Outline has been distributed. All students enrolled in the subject must be notified and have the opportunity to provide feedback in relation to the proposed amendment, prior to the amendment being finalised. Learning Analytics “Where Learning Analytics data (such as student engagement with Moodle, access to recorded lectures, University Library usage, task marks, and use of SOLS) is available to the Subject Coordinator, this may be used to assist in analysing student engagement, and to identify and recommend support to students who may be at risk of failure. If you have questions about the kinds of data the University uses, how we collect it, and how we protect your privacy in the use of this data, please refer to https://www.uow.edu.au/about/privacy/index.html”.
