    Practicals
    Note that practical classes begin in week 1 of the semester. Students must attend their allocated practical class in week 1, when further instructions on the operation of the laboratory session will be provided. Occupational Health and Safety inductions will be conducted at these times.

    Small Group Discovery Experience
    The course includes the level 2 Small Group Discovery Experience (SGDE)  which is a minor research project undertaken under the supervision of an experienced member of academic staff, aimed at providing insight into  the role of experimental work in the design and analysis of electrical circuits.

    In the second half of the semester students will be assigned a minor research topic related to circuit design and verification.  This
    will provide an opportunity to reflect on the significance of the experimental work conducted in the first half of the semester.  There will be two formal meetings with their academic supervisor, followed by a period of independent investigation and the group will present its findings in a seminar at the end of semester.  A mark will be assigned based on the content of the presentation and  individual participation throughout the exercise.


  • 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
    Assessment activity Type Weighting Due date Learning objective addressed
    On-line quizzes Formative 0% Weeks 4, 10 1-8
    In-class quizzes Summative 10% Weeks 6, 9 1-8
    Homeworks Formative 10% Weeks 2,4,6,8,10,12 1-8
    SGDE participation and presentation Formative 5% Weeks 7-12 10
    Practicals Summative – Hurdle 20% Weeks 1-6 1-10
    Exam Summative – Hurdle 55% End of semester 1-8
    Assessment Related Requirements
    The examination and the practicals are hurdle requirements. It is necessary to achieve at least 40% in the exam and at least 40% in the practical assessment. If this is not achieved, the total course mark will be limited to a maximum of 49.

    A hurdle requirement is defined by the University's Assessment for Coursework Programs policy as "...an assessment task mandating a minimum level of performance as a condition of passing the course.

    If a student fails to meet a hurdle requirement (normally no less than 40%),and is assigned a total mark for the course in the range of 45-49, then the student is entitled to an offer of additional assessment of some type. The type of assessment is to be decided by the School Assessment Review Committee when determining final results. The student’s final total mark will be entered at no more than 49% and the offer of an additional assessment will be specified eg. US01. Once the additional assessment has been completed, this mark will be included in the calculation of the total mark for the course and the better of the two results will apply. Note however that the maximum final result for a course in which a student has sat an additional assessment will be a “50 Pass” .

    If a student is unable to meet a hurdle requirement related to an assessment piece (may be throughout semester or at semester’s end) due to medical or compassionate circumstances beyond their control, then the student is entitled to an offer of replacement assessment of some type. An interim result of RP will be entered for the student, and the student will be notified of the offer of a replacement assessment. Once the replacement assessment has been completed, the result of that assessment will be included in the calculation of the total mark for the course.
    Assessment Detail
    Details of individual assessment tasks will be provided during the semester.
    Submission
    All written submissions to formative assessment activities are to be submitted electronically by 3:00pm on the specified date.

    No late submissions will be accepted. All formative assessments will have a two week turn-around time for provision of feedback to students.

    Full details can be found on the School website:
    http://eleceng.adelaide.edu.au/current-students/undergraduate/

  • 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.

    This course was offered for the first time in 2009.  SELT feedback for the course suggested:
     - The inclusion of more worked examples in lectures
     - The availability of more example problems for self-paced practice.
     - Better organisation of the practical work (which was shared between Circuit Analysis and    Electronics II)

    In 2010: 
     - Lecture material was revised to include more worked examples and to adjust the amount of time spent on each topic.
     - A suite of practice problems was made available.Practical work for Circuit Analysis and Electronics II was decoupled so that the two courses are fully independent.

    SELT feedback in 2010 suggested:
    - The inclusion of more worked examples in lectures and more challenging examples in tutorials and lectures, while exam results revealed some student weakness in understanding fundamental principles.

    In 2011: 
     - Some more complex examples were covered in lectures and tutorials
    - Lecture notes were expanded to include proofs of fundamental principles such as superposition
    and Thevenin’s theorem. These will be discussed in lectures.
    - The set of practice problems was expanded.
    - There were major revisions to the practical work

    SELT feedback in 2012 suggested:
    - The need for still more examples
    - More feedback from the on-line quiz system.

    In 2013:
    - The number of practice problems will be increased.
    - On-line quizzes will be revised to provide finer-grain feedback.
    - Assessment processes for the practicals are being revised.

    In 2015 the Small Group Discovery Experience was introduced with aim of
    providing more insight into the role of experimental work in circuit
    analysis and design.  The practicals were supported by better online
    introductions.

    There were no significant new comments arising from the SELT feedback in 2013 - 2015, apart from a continuing desire for more worked examples.

    In 2016 the two major homework exercises will be split into 6 smaller exercises, to provide more frequent and timely feedback on progress.  More on-line presentations will be used, supplemented by more interactive problem solving sessions in class.






  • 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.
