The University's policy on Assessment for Coursework Programs is based on the following four principles:

Assessment must encourage and reinforce learning.
Assessment must enable robust and fair judgements about student performance.
Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
Assessment must maintain academic standards.

Case Study:

As a food technologist you are asked to provide advice and guidance to the company that will address each of these issues. Specifically, you are asked to:
1. Develop a new design for the factory that prevents cross contamination and which complies with the Food Standards Code.
2. Identify new methods of freezing and new equipment that will increase the freezing rate of the seafood and which results in less damage to it.
3. Determine if fittings (e.g. pipework, threaded couplings, etc) in the factory could be replaced with more modern sanitary fittings that improve the hygiene and sanitation standards of the plant.
4. Identify how the application of hydraulics and pneumatics can improve material handling in the plant.
5. Considering the current process is mostly manually operated, suggest how the production processes could be improved by introducing automated methods of process control.
6. Methods of liquid waste treatment to meet EPA requirements; refer to Appendix I for specifications.
7. Strategies to reduce power consumption.

Oral presentation:

This include students choosing one engineering concepts topic, research and presenting to the class for 10 minutes with question time.

Final Exam:

Held in department closed book for 2 hours covering questions from all the lectures, oral topics and practicals.

Submission

All assessable components must be handed in at the Applied Food Studies Office, Regency TAFE by 12.00 pm of the due date.

Student Feedback

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Fraud Awareness

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
