Learning & Teaching Activities
Learning & Teaching Modes
This course will be delivered by the following means:
- 3 lectures of 1 hour per week
- 1 workshop of 1 hour per week
- 1 practical of 3 hours per fortnight
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).

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.
Assessment task Type of assessment Percentage of total assessment for grading purposes Hurdle (Yes/No) Outcomes being assessed Workshop preparation and participation Formative & Summative 5-10% No 1 – 4, 8 – 10 Practical work Formative & Summative 20% Yes
(30% in earch practical and 40% overall)
1 - 10 In – Semester Tests Formative & Summative 5% - 20% No 1-4, 10 Written Examination Summative 50% - 70% No 1 – 4, 10
Assessment Related Requirements
To obtain a grade of Pass or better in this course, a student must achieve a result of at least 30% in each practical and an overall result of 40% for the practical component and attend the final examination.
The coursework result comprises a contribution from your preparation for tutorials with the remainder from the in-semester tests and your written examination. The MyUNI quiz and the experimental work contribute to the result for practical work.
Workshop preparation and participation
Workshops are held weekly, starting in the second week. The grade for the workshop is based on the student’s preparation and participation during the workshop. Poor workshop results can be partly replaced by a better performance in the final exam.
The workshop mark can contribute up to 10% of the final course grade if it improves the mark for the coursework component. Otherwise, the workshop mark contributes 5% and the result for the written exam is more highly weighted.
There are five practical sessions which are all compulsory. For each practical, the student must obtain a Satisfactory result in the preparatory work, attend the practical session and submit the logbook for assessment. During the practical sessions, students work in groups of 2 or 3. The students in each group will select one of their completed experiments and cooperate to prepare a scientific poster which is presented in the final practical session. This poster will count for 25% of the practical assessment component.
In – Semester Tests (5% -20% of the total course grade)
Up to 4 tests will occur throughout the semester. Poor results in the tests can be partly replaced by a better performance in the final exam. This is achieved by varying the contribution of this task towards the total assessment to optimise the final result for each student. If the in-semester tests contribute less than 20% towards the final grade then the written exam will be more highly weighted.
Examination (50% - 70% of the total course grade)
The final examination will be based primarily on lecture/workshop material.
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 for Assessment Tasks
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 supplementary 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. The assessment extension application form can be obtained from: http://www.sciences.adelaide.edu.au/current/
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 the assignment 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 late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
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 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.
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.

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.
