  • 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
    • Assignments 20%: to exercise and apply the individual topic knowledge learned; learning outcomes addressed 1, 2, 3, 4, 5, 6 and 7;
    • Practicals 10%: to integrate, exercise and apply the learned knowledge to simulate and realise various circuits as well as to learn the use of electronic instruments; learning outcomes addressed 1,3 4, 5, 6 and 8;
    • Final exam 70%: to test how well students have learned the knowledge covered and how well the knowledge could be applied to solve relevant engineering problems; objectives addressed 1, 2, 3, 4, 5, 6, 7 and 8;
    Assessment Related Requirements

    Continuous assessment is required which needs the students to pass the assignments (averaged) and practicals (averaged) to sit for the final examination.

    Assessment Detail
    • Assignments: Assignments will be set and related to the topics described in Section 4.3 learning activity summary.
    • Practicals/Simulations: The use of electronic instruments, RC circuits, operational amplifiers, diode circuits, BJT circuits, FET circuits, and PSPICE simulations will be carried out.
    • Final exam: The final exam will be set to test the electronic knowledge learned.
    Submission

    Assignments and project report (hardcopy) need to be submitted with cover sheet to the submission box, which has the correct course label, located on level 2 of Engineering South Building before the deadline. Electronic copies of practical reports as well as simulation files (PSPICE .sch files) need to be submitted to the email address that will be specified at the beginning of the semester. Every one day late submission (both assignments and practical reports) will incur 10% mark deduction. Due dates may be extended with genuine reasons which needs to communicate with the lecturer face-to-face or by emails. The turn-around timeline on assessments and the provision of feedback is two weeks after the submission deadline.

    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

    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.
