Specific Course Requirements

Laboratory: This course includes a laboratory: Flow Visualisation – 3 hrs. Details provided in level 2 Labbook.

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.

Assessment Summary

All learning objectives are assessed through assignments, laboratories and examination.

For 2014, Fluid mechanics: Assignments 20%, laboratory 10%, final exam 70%

Thermodynamics: Assignments 30%, final exam 70%

Assessment Related Requirements

The Laboratory is compulsory part of a course. If a lab session is missed or a lab report not handed in or a student fails to get at least 35% of the total possible lab marks, then that is grounds for FAILURE of the entire course.

Assessment Detail

Assignments – individual, distributed through the semester at least two weeks prior to a submission date

Laboratory – assessment based on lab participation and a report (COMPULSORY component)

Final exam – open-book, 3 hours,

Submission

Assignments and lab reports should be submitted via corresponding Course Submission Box located on Level 2 of Engineering South. No late submissions are accepted although in special cases exemptions can be granted on individual basis. A “turn-around” timeline on assessments and the provision of feedback to students is approximately 2 weeks. Re-submission of work is not allowed.

Course Grading

Grades for your performance in this course will be awarded in accordance with the following scheme:

M10 (Coursework Mark Scheme)
Grade	Mark	Description
FNS		Fail No Submission
F	1-49	Fail
P	50-64	Pass
C	65-74	Credit
D	75-84	Distinction
HD	85-100	High Distinction
CN		Continuing
NFE		No Formal Examination
RP		Result Pending

Further details of the grades/results can be obtained from Examinations.

Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.

Final results for this course will be made available through Access Adelaide.

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.
