Learning & Teaching Activities
Learning & Teaching Modes
Lectures are supported by solved examples, problem-solving tutorials, and real case studies.
Online learning is also available through MyUni.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.
The standard undergraduate workload for a full-time student is 48 hours per week which equates to approximately 12 hours per 3 unit course. The workload associated to this course involves 5 hrs of lectures and tutorials per week. You would be expected to spend an approximately twice the number of hours outside class-revising notes, reading more widely about the topics covered, practicing examples, finishing exercises, homework etc. The University Learning and Teaching Committee has recently agreed that 3 unit courses are required to have a minimum workload of 150 hours regardless of the length of the course.

Specific Course Requirements
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 SummaryThe course will be assessed with a weighting of 40% on assignments, and 60% based on the results of the final exam. Lecturers for each of the three sections will provide further details during class.
Task Type Assessment Weighting Learning Outcomes Sum-Form Assignments/Numerical problems on selected topics 40% • Analyse, and devise relevant solutions to problems posed within the course, individually and with team mates
• Apply theoretical and practical skills in real problems through case studies
Summative Final exam 60%
Assessment Related Requirements
Further details on assignments will be given during class or through MyUni at least two weeks in advance of the submission date.
You will be advised of the date, time and location for physical submission of all assignments during class or through MyUni
Submission of Work for Assessment
Practical class exercises should be submitted in hardcopy with a completed copy of the assessment coversheet that is available from the school office. This should be signed to indicate you have read the university policy statement on plagiarism, collusion and related forms of cheating.
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 Co-ordinator or lecturer before the assessment task is due. Extensions will not be provided on the grounds of poor prioritising of time.
Penalty for Late Submission of Assessment Tasks
Assessment tasks must be submitted by the stated deadlines. There will be a penalty for late submission of assessment tasks. The submitted work will be marked ‘without prejudice’ and 10% of the obtained mark will be deducted for each working day (or part of a day) that an assessment task is late, up to a maximum penalty of 50% of the mark attained. The Course Co-ordinator or lecturer / examiner may elect not to accept any assessment task that a student wants to submit after that task has been marked and feedback provided to the rest of the class.
Provision of Feedback to Students
Feedback will be provided to students within four weeks of a test and assignments submission.
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.
