ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:
The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the Academic Integrity . In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.
Moderation of Assessment
Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.
This course will include an online exam at the end of the course, to be held on Tuesday 9 June 2020. Further details about this can be found under Assessment Task 4.
Assessment Task 1
Learning Outcomes: 1,4,5,8
Students are required to post into Q&A forums to demonstrate their conceptual understanding of topics, and as preparation for “short answer” questions in the final exam. There are three forums, broadly keyed to areas of Description, Validation and Population. Students will have until the dates posted on the Wattle site to post their answers for each forum. After this time, grades will not be awarded for posts on the respective forum.
There are multiple activities associated with this task with individual due dates. The dates for the Forums are as follows:
Key Area: Description
Covers Topics Taught in Weeks: 1-4
Due Mon 30 March 2020
Key Area: Validation
Covers Topics Taught in Weeks: 5-7
Due Mon 4 May 2020
Key Area: Population
Covers Topics Taught in Weeks: 8-10
Due Mon 25 May 2020
In a Q&A forum, several questions are asked, which are related to the material covered in the preceding topics, and students answer one or more of them. Once they have posted an answer, the student will be able to view other students’ responses and can reflect on their viewpoint. They may choose to discuss the responses further.
The convenor will award a grade for the first post on each question, which will be visible to the student. If a student posts on more than one question in a forum, the single post with the highest mark from that forum will contribute to a student’s grade. Each forum is worth 5% of the total mark for the course (total 15%).
Posts should be thoughtful and constructive, and preferably involve reference to other academic or official sources. References must be cited in an appropriate manner. Each post should be about 200-300 words (not including References). Students are encouraged to return to the forum and read the feedback provided by the convenor, for their own posts, and the posts of other students. This will help guide students on the expectations in the final exam.
The table below gives an indication of how marks are awarded in the Q&A forums.
These postings are made in time for others to read and respond, deliver information that is full of thought, insight, and analysis, make connections to previous or current content or to real-life situations, contain rich and fully developed new ideas, connections, or applications. References are cited correctly.
These postings are made in time for others to read and respond, deliver information that shows that thought, insight, and analysis have taken place, make connections to previous or current content or to real-life situations, but the connections are not really clear or are too obvious, contain new ideas, connections, or applications, but they may lack depth and/or detail. References are cited correctly.
These postings may not all be made in time for others to read and respond, are generally competent, but the actual information they deliver seems thin and commonplace, make limited, if any, connections, and those art often cast in the form of vague generalities, contain few, if any, new ideas or applications; often are a rehashing or summary of other comments.
These postings may not have been made in time for others to read and respond, are rudimentary and superficial; there is no evidence of insight or analysis, contribute no new ideas, connections, or applications, are off topic.
Postings that are different to those described above.
Not counted eg student query to another student.
Evidence of plagiarism.
Assessment Task 2
Learning Outcomes: 1,3,4,5
The four topic-based online quizzes are designed to prompt students to revise the material covered in lectures and tutorials. Each quiz will cover material up to the previous week (e.g. Quiz 1 covers material from weeks 1 and 2). The final quiz may cover material from the entire course.
Marks from all four quizzes count towards the total quiz mark. Each individual quiz is worth 5% of the overall mark for the course (total 20%). No quiz can be taken after it has closed. Therefore, failure to complete any of the quizzes within the allotted time, without prior permission from the Convenor, will result in a zero grade for that quiz. Quizzes will be available on the following dates:
Quiz 1 - Wed 11 March 2020
Quiz 2 - Wed 25 March 2020
Quiz 3 - Wed 22 April 2020
Quiz 4 - Wed 20 May 2020.
Each online quiz will be available on Wattle for a limited time. Once started, students must continue until completed, as each quiz allows only one attempt per student. There is a 60 minute time limit for each quiz. The format is open- book, so students may make use of course materials and textbooks while taking any quiz. Calculators are also permitted. Students must complete each quiz as individual work. This means sharing or discussing answers with others is not allowed and collusion will be treated seriously.
Assessment Task 3
Learning Outcomes: 2,6,7,8
This assessment task involves writing a critique of a published epidemiological study and contributes 30% of the total mark for the course. The journal article will be available on Wattle at the end of week 7. Due date will be posted on the Wattle site.
A critical appraisal is a careful and systematic review of a piece of research to assess the strengths and limitations of the study. The primary aim of this assessment task is for students to demonstrate that they understand the key epidemiological concepts covered throughout the course.
- Do not include a title page or cover sheet.
- Document names should not be longer than 50 characters.
- 12-point of any font type is acceptable, with line spacing of 1.5 lines and page margins of at least 2.5cm on all sides.
- Each page should be numbered.
- Headings and sub-headings may be used to structure your Critical Appraisal, but full sentences are required throughout (ie. do not write in bullet points at all).
- Limit your Critical Appraisal to 2000-2500 words. Avoid lengthy introductory material or a paragraph telling the readers what you will tell them. If there are too many issues to cover well within the word limit, choose the most important issues to discuss. Write the word count (not including References or Declaration) at the end of the text.
Guidelines for writing a Critical Appraisal
Although a critique will include some descriptive statements about the study, the main focus is careful reasoning to clearly and objectively make a judgment about the piece of research. The emphasis should be on a synthesis and interpretation of the material and not simply a description of the study or a recitation of facts. It should focus less on statistical issues and concentrate more on the basic concepts of epidemiologic research design and the validity of the inferences that are drawn. For the purpose of this task, it is acceptable to assume that the correct statistical methods have been used.
To fulfil this requirement, your Critical Appraisal should include three sections, as below:
- In no more than 150 words, concisely describe the study’s objective, methods and main finding(s).
- Systematically, and critically, review the methods (ie. study design, bias, confounding and chance) to assess the study quality and validity of the findings. (Students may wish to make use of Figure 9.1 Issues to consider when reading epidemiological papers; see Wattle or Webb & Bain 3e 2017 p.261).
- Weigh up the strengths and limitations of the study and make recommendations on how future studies might be designed in order to provide stronger evidence either for or against the existence of a relationship between the exposure and the outcome.
Students will need to appropriately acknowledge source material for this assessment piece. It is recommended that in-text citations use numbers, such as Vancouver style, so that they are not included in your word count. Where possible, references should be drawn from the past eight years. If you are unsure whether, or how, to acknowledge source material, you can make use of the resources offered by the ANU Academic Skills and Learning Centre. Students can obtain free and confidential help with their academic work through individual consultations, workshops, courses, podcasts and handouts.
ANU students are encouraged to use EndNote, which is software that allows a researcher to build libraries of references and insert them as citations into assignments, theses and papers. Using EndNote helps ensure the consistency of references and automates much of the work of formatting references. More information about EndNote, and links to download it for free, can be found at http://libguides.anu.edu.au/endnotehowtoguide.
- Marks will be awarded according to the following criteria:
- Demonstrates an understanding of epidemiological concepts and methods
- Demonstrates an ability to reflect critically on the methodological rigour and reliability of the findings from an epidemiological study
- Clear expression of ideas and the presentation of a cogent argument
- Adherence to word limit and format requirements
- Referencing that is undertaken accurately and as necessary
For maximum marks, evidence of critical thinking in the synthesis and interpretation of the selected study and application of the key concepts covered throughout the course must be demonstrated within the word limit.
Unless an extension has been arranged beforehand, assignments submitted after the due date will be penalised by 5% of the possible marks available per day (or part thereof).
In fairness to students who submit on time and cannot have their marked assignments returned until every student has submitted, late assignments will not be accepted after ten working days; if a student is unable to submit by that time, alternative assessment may be set by the Convenor.
Assessment Task 4
Learning Outcomes: 3,5,6,7
The online exam contributes 35% of the total mark for the course. The questions are based on a published epidemiological study (journal article), but may refer to any topic covered in the course. Calculations may be required. The journal article will be available on Wattle at least 24 hours before the assessment.
Students will have 2 hours to complete all questions. The format is open-book, so students may make use of reference materials (including course notes, textbooks and bilingual dictionaries). Work must be individual and students may not share answers or speak with others during the exam. Collusion will be treated seriously. Calculators may be used.
Marks for each question are indicated next to the question; students may use these as a guide to the level of detail required for the answer.
Please refer to the course Wattle site for the exam date.
Academic integrity is a core part of the ANU culture as a community of scholars. At its heart, academic integrity is about behaving ethically, committing to honest and responsible scholarly practice and upholding these values with respect and fairness.
The ANU commits to assisting all members of our community to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. The ANU expects staff and students to be familiar with the academic integrity principle and Academic Misconduct Rule, uphold high standards of academic integrity and act ethically and honestly, to ensure the quality and value of the qualification that you will graduate with.
The Academic Misconduct Rule is in place to promote academic integrity and manage academic misconduct. Very minor breaches of the academic integrity principle may result in a reduction of marks of up to 10% of the total marks available for the assessment. The ANU offers a number of online and in person services to assist students with their assignments, examinations, and other learning activities. Visit the Academic Skills website for more information about academic integrity, your responsibilities and for assistance with your assignments, writing skills and study.
You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records. Unless an exemption has been approved by the Associate Dean (Education) submission must be through Turnitin.
For some forms of assessment (hand written assignments, art works, laboratory notes, etc.) hard copy submission is appropriate when approved by the Associate Dean (Education). Hard copy submissions must utilise the Assignment Cover Sheet. Please keep a copy of tasks completed for your records.
Individual assessment tasks may or may not allow for late submission. Policy regarding late submission is detailed below:
- Late submission not permitted. If submission of assessment tasks without an extension after the due date is not permitted, a mark of 0 will be awarded.
Accepted academic practice for referencing sources that you use in presentations can be found via the links on the Wattle site, under the file named “ANU and College Policies, Program Information, Student Support Services and Assessment”. Alternatively, you can seek help through the Students Learning Development website.
It is intended that the marked forums will be returned within 2 weeks after submission, and the marked quizzes will be returned within 1 week after submission. Feedback will be provided via the course Wattle site.
It is intended that the marked critical appraisal assignment will be returned within 3 weeks after submission. Feedback will be provided via the course Wattle site.
The exam marks will be available via the course Wattle site on the date final results are published on ISIS.
Extensions and Penalties
Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure. Extensions may be granted for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date.
