    Online Learning
    This course will use a variety of online resources to support the learning process. Recorded slide presentations on key concepts, theory and methods will be made available prior to scheduled lectures, at which the content of the presentations will be discussed in more detail, in the context of applications and problem-solving exercises. It is essential that student view the slide presentations or read the slides before attending lectures.

    Video recordings of lectures will normally be made available on the course website after each lecture.

    In addition, the following material will be provided on the course website at the start or during the course of the semester:
    • slides, slide presentations, and tutorial questions
    • some past assessment examples (tests and exams)
    • additional practice questions

    All course announcements will be made via the course website..

    The use of the course discussion boards is strongly encouraged for questions relating to course material, but also for more general discussion on electrical and electronic engineering and technology. Anonymous posts will be permitted were possible, offensive posts will not. Lecturers will make a best effort to respond promptly to questions raised on the discussion boards.

    The course gradebook will be used to return continuous assessment marks. Students should check the gradebook regularly and confirm their marks have been correctly entered.


  • Learning & Teaching Activities
    Learning & Teaching Modes
    This course uses on-line content, lectures, tutorials and practicals to achieve its learning objectives. Students will be expected to prepare for lectures by viewing online slide presentations explaining the theory and concepts that are the foundation of learning in this course.  Lectures will be largely devoted to demonstrations and active learning activites that explain the context and application of the theory, develop a deeper undersatnding of the key concepts, and provide an opporuntity to practice solving problems. Tutorials will be used for assisted problem-solving by students, working individually or in groups. Students are expected to prepare before tutorials and this preparation will be assessed as part of the weekly online test. There is also a small assessment componet for active participation in tutorials.

  • 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.

    This assessment breakdown is registered as an exemption to the University's Assessment for Coursework Programs Policy. The exemption is related to the Procedures clause(s): 1. b. 3.   
     
    This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course.
    Assessment Related Requirements
    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.

    In the Analog Electronics course the examination and practical components are hurdle requirements. It is necessary to achieve at least 40% in each one of these components. If the exam hurdle requirement is not achieved, the total course mark will be limited to a maximum of 49. If the practical requirement is not met, the total course mark will be limited to a maximum of 44.

    It is important to note there is NO supplementary assessment offered for the practical component after the end of Week 12. By arrangement with the Practical Coordinator, it will be possible throughout the semester for students who are falling significantly behind to have supplementary opportunities. However if students persistently neglect the practical component throughout semester they are likely to not meet the hurdle requirement and hence fail the course without further opportunity for redemption. Exceptions will be made in the case of verifiable medical or compassionate circumstances beyond the student’s control.

    If a student fails to meet a hurdle requirement, 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 e.g. 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.

  • 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.

    The following changes have been made in response to sutudent feedback from 2018
    • Tutorial preparation will be assessed as part of the weekly online test
    • The format of the tutorials has been adjusted to be more inline with the mathematics "whiteboard tutorials" and to encourage students to collaborate in small groups.
    • There will be a small component of the assessment awarded for tutorial preparation.
    • The course resources including lecture notes and slide presentations for Topics 5 and 6 have been updated.
  • 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.
