  • Assessment

    The 最新糖心Vlog'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

    There are 6 assignments, each worth approximately 2.5% or 5% of the assessment, and a laboratory that is worth 10% of the assessment. The open book exam is worth 70%. All assignments are due by 5:00pm on the due date. The 5% assignments are design-based problems of greater complexity.  Details of each task are tabulated below. This schedule is subject to change during the semester. See MyUni for details. In the table below, “Incomp” refers to Incompressible flow and “Comp” refers to compressible flow.

    Assessment Detail

    Assignments

    All assignments will are based on a problem-solving format. In each case a practical problem will be presented and the students will be asked to provide a solution to that problem. The problem format and difficulty are the same as the final exam. Each student’s submission will be assessed primarily on the quality of their approach to the problem. Students are required to state all assumptions used in their solutions, provide appropriate diagrams, and to follow a standard presentation procedure known as the “problem solving protocol”. Approximately 10% of the marks of each problem are awarded for fulfilling these requirements.

    Laboratory

    This laboratory consists of two parts. The first part is an experimental investigation of the pressure distribution over a wing using a wind tunnel. Students will be required to measure the pressure distribution and use the measured data to calculate the lift and pressure drag on the wing. The second part is an experimental investigation of a commercial pump using a pump testing rig. The students will measure the pressure rise and flow rate through the pump at a range of load conditions, sufficient to construct the pump performance curve. Students are required to submit group reports for each laboratory. Students must have submitted a report and scored at least 35% overall to be eligible to pass the course. Further details are provided by the laboratory demonstrators.

    Submission

    Individual assignments are to be submitted by each student to the submissions box on Level 2, Engineering South Building. Unless students are otherwise notified, assignments must be submitted by 5.00pm exactly two weeks after each assignment is issued. Submitted assignments must be accompanied by an assessment cover sheet, available from room S116 or near the assignment submission area. Late assignments will be penalised 10% per day. Extensions for assignments will only be given in exceptional circumstances and a case for this with supporting documentation can be made in writing after a lecture or via email to the lecturer. Assignments will be assessed and returned in 2 weeks of the due date, along with a “model” solution prepared by the lecturer. There will be no opportunities for re-submission of work of unacceptable standard. Due to the large size of the class, feedback on assignments will be provided by limited comments on the returned assignments and general feedback given during the lectures and tutorials.

    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 .

  • Student Feedback

    The 最新糖心Vlog 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 最新糖心Vlog 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鈥檚 disciplinary procedures.

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