Learning & Teaching Modes

The Electric Energy Systems course uses the following learning and teaching activities:

1. Lectures: these are pre-recorded and students will need to watch on average about 3 hrs of lectures per week.

2. Online Quizzes: these are MyUni quizzes which are done weekly and require about 2 hrs per week.

3. Workshops: there are eight 2-hr workshops during the semester with preparation submitted before each one. The preparation is expected to take on average about 2 hrs per workshop.

4. Tutorials: there are five 1-hr tutorials during the course in which a more indepth discussion of the material will be given.

5. Quiz: there is a 1.25 hr open-book test held during week 6. At least 6 hrs of preparation is recommended.

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 University'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.

This assessment breakdown is registered as an exemption to the University's . The exemption is related to the Procedures clause(s): 1. b. iii.

This course has two 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 as "...an assessment task mandating a minimum level of performance as a condition of passing the course.

The experimental component is a hurdle requirement. It is necessary to achieve at least 50% for the weighted total of the three reports. If
this is not achieved, the total course mark will be limited to a maximum of 49.

The examination component is also a hurdle requirement. It is necessary to achieve at least 40% for the exam. If this is not achieved, the total course mark will also be limited to a maximum of 49.

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 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

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

Submission

There will be a late penalty of 10% of the maximum mark per day (or part of) for the experimental reports. There will be a penalty of 10% of the maximum mark for not attending your scheduled experiment session without prior approval or acceptable reason.

All formative assessments will be targeted to have a two-week turn-around time for provision of feedback to students.

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
FNS		Fail No Submission
F	1-49	Fail
P	50-64	Pass

NFE		No Formal Examination
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 .

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.

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鈥檚 disciplinary procedures.
