The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

• 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
Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching.
Asessment taskType of assessmentPercentage of total assessment for grading purposesHurdle (Yes/No)Outcomes being assessed
Test 1 (Circuit Theory) Summative 15% No 1 - 10
Test 2 (Electromagnetism) Formative & Summative 11% No 2 - 5, 10
Workshop preparation Formative & Summative 11% No Weekly
Practical work Formative & Summative 18% Yes *** 6 - 10
End of Semester Test Summative Min 45% Yes (40%) 2 - 5, 10
##### Assessment Related Requirements

To obtain a grade of Pass or better in this course, a student must maintain a suitable logbook for at least 5 practical sessions during the semester, attend the examination and achieve at least 40% in the final exam.

##### Assessment Detail

Tests
The circuit theory component is assessed by a 45 minute test during semester. The test contributes 15% of the final grade. There is no circuit theory component in the final exam.

The electromagnetism component is assessed by a 45 minute test.. This test has a formative and summative role and addresses essential aspects of the learning objectives. This test contributes 11% of the final assessment.

Workshop preparation
There are 11 tutorials contributing 11% of the final assessment. Students need to hand in a copy of their work on the tutorial questions by 4 pm on the night before their tutorial. The work is assessed on both effort and the correct implementation of course concepts.

Practical work (Practical achievement and practical reports)
Students work on an experiment until it is completed and they have an adequate report in their log book. Demonstrators provide formative assessment as the students are doing each experiment. Each student then selects one completed experiment and writes an extended lab report. The log book and report are assessed summatively.

End of Semester Test
This summative assessment activity comprehensively addresses learning objectives 1 - 10.

##### Submission

Submission of Assigned Work
Coversheets must be completed and attached to all submitted work. Coversheets can be obtained from the School Office (room G33 Physics) or from MyUNI. Work should be submitted via the assignment drop box at the School Office.

Extensions of deadlines for assessment tasks may be allowed for reasonable causes. Such situations would include compassionate and medical grounds of the severity that would justify the awarding of a replacement examination. Evidence for the grounds must be provided when an extension is requested. Students are required to apply for an extension to the Course Coordinator before the assessment task is due. Extensions will not be provided on the grounds of poor prioritising of time.

Late submission of assessments

If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days or more late without an approved extension can only receive a maximum of 50% of the mark.

Grades for your performance in this course will be awarded in accordance with the following scheme:

M10 (Coursework Mark Scheme)
FNS   Fail No Submission
F 1-49 Fail
P 50-64 Pass
C 65-74 Credit
D 75-84 Distinction
HD 85-100 High Distinction
CN   Continuing
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 Access Adelaide.

• 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.

• 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 studentâ€™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.
