Assessment
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 Summary
Assessment Task Weighting (%) Individual/ Group Formative/ Summative Due (week)* Hurdle criteria Learning outcomes Assignments 20 Individual Summative Weeks 2-12 1. 2. 3. 4. 5. 8.

This assessment breakdown is registered as an exemption to the University's . The exemption is related to the Procedures clause(s): 1. b. 2.
This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course.
The Hurdles are:
* Minimum Practical Grade of 50%
* Minimum exam grade of 40%
Assessment Related Requirements
The Practical is compulsory part of a course. If a practical session is missed or a lab report not handed in or a student fails to get at least 35% of the total possible lab mark, then that is grounds for FAILURE of the entire course.
Assessment Detail
Assignments – individual, distributed through a semester two weeks prior to a submission date
Practical – assessment based on practical participation and a report
Online Quizzes - short online quizzes to reinforce recent leture materialFinal exam – open-book, 3 hours.
Submission
Assignments and practical reports should be submitted via corresponding link on myuni. A penalty for late submission will be applied – 10% per day. In special cases extensions can be granted on individual basis. A “turn-around” timeline on assessments and the provision of feedback to students is approximately 2 weeks. Re-submission of work is not allowed.
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 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 .

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.
