Many journals also specialise in epidemiological research. The International Journal of Epidemiology, Epidemiology, Journal of Epidemiology & Community
Supplementary reading material may also be placed on MyUni throughout the course, as required.
Learning & Teaching Activities
Learning & Teaching ModesThere are a number of teaching and learning modes in this course.
Lectures: Provide basic factual information and introduce and illustrate concepts.
Tutorials: Provide an opportunity to develop understanding of lecture material and clarify concepts.
Practicals: A forum for application of lecture material. They provide an interactive forum to apply concepts from lectures and clarify understanding.
Assignments: Opportunity for independent application and exploration of key concepts.
Exam: To assess the extent to which understanding has developed through the course and can be applied in novel scenarios.
Online discussion for each tutorial and practical will be put on MyUni. Students will be able to post questions and answers to a discussion board and provide feedback about each other’s proposed research question. Online asynchronous or synchronous discussion will be facilitated through MyUni using discussion board, webchat, Collaborate or Skype depending on the students’ preference and availability. The discussions will be schedule to align with the related assessments tasks and facilitated by course coordinator.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.In general, 3-4 hours of independent study will be required each week, in addition to class time. This includes reading the set text, wider reading, preparing answers to tutorial questions, and making progress with assignments.

Small Group Discovery ExperienceN/A
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 Assessment Type Weighting Learning course objective(s) being addressed Assignment 1 Summative 20% 1, 2, 3, 6 Assignment 2 Summative 20% 4, 5, 6, 7 Examination Summative 60% 1-8
Assessment Related RequirementsNone.
Assessment DetailThere will be two assignments and an examination in this course. All assignments will be posted on MyUni at least 2 weeks prior to the date of submission. Students will be required to participate in an on-line, open book examination for a period of two hours that will be scheduled in synchrony for all students.
1) Students are expected to prepare for tutorials by attempting the tutorial questions before the scheduled session.
2) Students are expected to actively participate in tutorials and practicals.
3) Students must submit both assignments to be permitted to sit the exam.
Students are required to submit two assignments (weighting 20% for each, with a total of two written assignments, 40%). Assignment 1 will be provided to students and posted on MyUni at the start of Week 2, and Assignment 2 will be posted on MyUni at the start of Week 8. Students will be asked to use core epidemiological concepts, to correctly conduct disease measurements, and to critically assess and interpret epidemiological research findings from health literature.(1,000 words each assignment)
A two-hour exam at the end of course (weighting 60%) will assess your learning on the content of all lectures, tutorials and practicals as indicated previously.
All extensions for assignments must be requested, at the latest, by the last working day before the due date of submission. Extensions will generally be granted only on medical or genuine compassionate grounds. Supporting documentation must be provided at the time a student requests an extension. Without documentation, extensions will not be granted. Late requests for extension will neither be accepted nor acknowledged.
Only the Course Co-ordinator(s) may grant extensions.
Supporting documentation will be required when requesting an extension. Examples of documents that are acceptable include: a medical certificate that specifies dates of incapacity, a police report (in the case of lost computers, car & household theft etc.), a letter from a Student Counsellor, Education and Welfare Officer (EWO) or Disability Liaison Officer that provides an assessment of compassionate circumstances, or a letter from an independent external counsellor or appropriate professional able to verify the student’s situation. The length of any extension granted will take into account the period and severity of any incapacity or impact on the student. Extensions of more than 10 days will not be granted except in exceptional circumstances.
Marks will be deducted when assignments for which no extension has been granted are handed in late.
All assignments, including those handed in late, will be assessed on their merits. In the case of late assignments where no extension has been granted, 5 percentage points of the total marks possible per day will be deducted. If an assignment that is 2 days late is awarded 65% on its merits, the mark will then be reduced by 10% (5% per day for 2 days) to 55%. If that same assignment is 4 days late, the mark will be reduced by 20% (5% per day for 4 days) to 45%, and so on.
The School of Public Health reserves the right to refuse to accept an assignment that is more than 7 days late.
Assignments submitted after the due date may not be graded in time to be returned on the listed return dates.
Students submitting examinable written work who request (and receive) an extension that takes them beyond the examination period are advised that there is no guarantee that their grades will be processed in time to meet usual University deadlines.
If a student is dissatisfied with an assessment grade they should follow the Student Grievance Resolution Process <https://www.adelaide.edu.au/student/grievance/process/>. Students who are not satisfied with a particular assessment result should raise their concerns with Course Co-ordinator(s) in the first instance. This must be done within 10 business days of the date of notification of the result. Resubmission of any assignment is subject to the agreement of the Course Co-ordinator(s) and will only be permitted for the most compelling of reasons.
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.
