Required Resources

The following required resources are available on MyUni:

• Lecture notes: you can print these yourself, or purchase them from EEESAU (the local student branch of the Electrical and Electronic Engineering student society) at the beginning of the semester at reasonable cost, see signs around the Ingkarni Wardli building.

• Online tests: these are both available and submitted on the course MyUni website.

• Tutorial questions: these are available on the MyUni website in the week leading up to the tutorial.

Recommended Resources

1) Practice problems are available on MyUni for most of the course segments. Some of these will be used in the online tests and tutorial questions.

2) Reference Books
The course lecture notes should provide sufficient information for most students, however you may find the following reference book useful if you are have difficulty with the material or are interested in learning more about any of the topics in this course.
Copies of the following books are available in the Barr Smith library.
• T. Wildi : “Electrical Machines, Drives, and Power Systems”, Prentice Hall, 6th edition.
• P.C. Sen: "Electric Machines and Power Electronics Principles", Wiley, 2nd edition.

Online Learning

All course announcements will be made via MyUni. They will be available on the MyUni announcement board.

The weekly online tests are conducted on the course MyUni website.

The use of the MyUni discussion boards is strongly encouraged for questions relating to course material. Lecturers will make a best effort to respond promptly to questions raised on the discussion boards.

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

Audio (and if facilities are available, also video) recordings of lectures will be made available on MyUni. The video recordings consist of the image displayed on the digital projector. Note some lecture theatres have two digital projectors and in this case only the content displayed on one of the projectors will be available.

In addition, the following material will be provided on MyUni at the start or during the course of the semester:
• Lecture notes and tutorial questions
• Past exams and quizzes
• Additional exercise problems

Tutorial problems should be attempted before the tutorial and this preparation is assessed at the start of each tutorial. The tutor will also go through selected questions on the board and students will be given opportunities to ask questions.

Online tests are automatically marked. Wrong answers are indicated and correct answers are provided. Students may attempt an online test as many times as they wish before its due date, but on each attempt will have to try all questions again. Some numerical values in questions may change between attempts. Students will be awarded the maximum mark from all of their attempts of a particular online test.

Specific Course Requirements

Laboratory clothing restrictions apply to the workshop sessions: closed-toe shoes; covered shoulders; long hair must be tied back. In addition, students must remove all hand and wrist based jewellery (including material bracelets), and must not eat or drink in the laboratories. Failure to adhere to these requirements will result in your removal from the laboratory.

The 最新糖心Vlog's policy on Assessment for Coursework Programs is based on the following four principles:

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

Assessment Related Requirements

A hurdle requirement is defined by the 最新糖心Vlog's as "...an assessment task mandating a minimum level of performance as a condition of passing the course.

In the Electric Energy System course there are two hurdle requirements, for which it is necessary to achieve at least 40% in,
• examination
• experimental section
If both of these are not achieved, the total course mark will be limited to a maximum of 49.

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.

It is important to note that there is no replacement assessment offered for the practical component.

Assessment Detail

See the notes for each assessment summary item in the table above.

Submission

All written submissions to formative assessment activities are to be submitted to the designated boxes within the School of Electrical & Electronic Engineering by 3:00pm on the specified dated and must be accompanied by a signed cover sheet. Copies of blank cover sheets are available from the School office in IW 3.26.

Late submissions of the experimental reports will be accepted but with a 20% penalty per day (or part of). All formative and summative assessments will have a two week turn-around time for provision of feedback to students.

Final results for this course will be made available through .

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.

This section contains links to relevant assessment-related policies and guidelines - all university policies.

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.
