  • Assessment

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

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

    Assessment Summary

    All assessment is summative.

    • Final Exam: 50%
    • 5 Individual Assignments: 25%
    • Group Assignment/Project: 15%
    • Laboratory (Turbine engine performance): 10%
    Assessment Task Weighting % Description Due date Learning objectives

    While every effort has been made to ensure that this information reflects an accurate plan, the coordinator reserves the right to make changes that ensure the continual improvement of the course. Any such changes will be made clear via MyUni.

    Assessment Related Requirements

    In order to pass this course, students must achieve a pass grade for the turbine engine performance laboratory.

    Assessment Detail
    • Final exam is a 3-hour long open book exam, to be conducted during the formal university examination period.

    • There will be 4 assignments in total. Three of these are individual assignments (no collaboration) and the other is a group assignment/project. These will be distributed during class and also placed on MyUni. Due dates for these assignments may be subject to change; any changes will be announced in-class, written on the assignment, and posted on MyUni at the time the assignment is first distributed.

    • The turbine engine performance laboratory is run as part of the formal Level IV laboratories.

    Submission

    Unless otherwise specified, submission of assignments and laboratory reports will be made through the hand-in boxes located next to the school office on Level 2 of Engineering South. Cover-sheets should be attached to all submissions (cover-sheets located next to the submission boxes).

    Late submissions will be penalized at 50% per day late. Submissions are due at 1pm. Extensions for assignments will only be given in exceptional circumstances and a case for this with supporting documentation must be made either in writing after a lecture, submitted in hard copy to the front office (to be passed on to the lecturer), or emailed to the lecturer directly.

    Assignments will be assessed and returned within 4 weeks from submission (usually significantly less). Assignments that are marked prior to the last class will be brought to class for students to collect. Any assignments not collected in-class will be left in the assignment collection boxes next to the elevator on level 2 of Engineering South. There will be no opportunities for re-submission of work of unacceptable standard. Due to the large class size, feedback on assignments will be limited to in-class discussion resulting from questions from students.

    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.

  • Student Support
  • Policies & Guidelines
  • 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.
