Learning & Teaching Modes

This course is divided into six modules, which are delivered over a period of 12 weeks. Each module focuses on a specific aspect of electric energy systems, including revision of basic electrical quantities and principles, AC circuits and phasors, stationary electromagnetic machines (transformers), rotating electromagnetic machines (including 3-phase AC induction and synchronous machines), and AC power networks. The course material will be delivered in a variety of ways, including lectures, tutorial discussions, and computer-based workshops. Some modules may also include laboratory experiments and formal reports. The course will conclude with an invigilated ( or proctored) exam, which covers material from all six modules.

The subject will be divided into six modules, delivered over 12 weeks.
Each module addresses a fundamental area of study in the field, of Electric Energy Systems:
[1] Revision of basic electrical quantities, physical laws, analysis and units
[2] AC circuits and the theory of Phasors
[3] Stationary electromagnetic machines (transformers)
[4] Rotating electromagnetic machines (part 1: 3-phase AC induction machines)
[5] Rotating electromagnetic machines (part 2: synchronous machines)
[6] AC Power networks

all modules contain:
1/ Delivery of material (pre-recorded? ...)
2/ Tutorial (or a non-assessed workshop) to discuss the material
3/ Assessed Workshop to solve problems explicitly on computers (with Python)
a small amount of coding may be required...
Workshops will be in groups and will carry small mark weightings

some modules will contain:
4/ a related laboratory experiment and formal report
These will carry more substantial mark-weightings

There will be one invigilated (or proctored) examination. It will cover approximately equal weighting for all of the six modules.

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 Summary

Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.

Assessment Task	Weighting (%)	Individual/ Group	Formative/ Summative	Due (week)*	Hurdle criteria	Learning outcomes
Practical exercises	27	Individual	Summative	Week 6		5. 6. 7.
Tutorials/Workshops	12	Collaborative	Summative	Weeks 2 - 12		6. 7. 8.
Examination	61	Individual	Summative	Exam Period	Min 40%	1-10.
Total	100

* The specific due date for each assessment task will be available on MyUni.

This assessment breakdown is registered as an exemption to the 最新糖心Vlog's . 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 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 assessment activities are to be submitted electronically on the specified date 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.

Full details can be found on the School website:

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.
