Assessment Overview
Assessment Grading
This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

Feedback, Recommendations and Responses
Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.
Feedback from Unit Coordinator reflection
There was very limited student attendance and participation in the weekly online tutorial due to timing of the tutorial session, resulting in missed and limited learning opportunities for students.
Review the timing of the weekly tutorial sessions to encourage better student attendance and engagement in future iterations of the unit.
Feedback from Unit Coordinator reflection
Attendance in the bi-weekly clarification drop-in sessions for students to seek any clarification or ask questions regarding the previous weekly content and tutorial questions were poorly attended throughout the term.
Trial the bi-weekly clarification drop-in sessions in the next delivery of the unit to gain more insight on its use by the students.
Feedback from Unit Coordinator reflection SUTE
Many students do not appreciate the unit or see the relevance of this unit to their degree despite the unit being a pre-requisite for the CB77 Year 3 unit MEDI13007: Fundamentals of Radiographic Technique, the scope and content being reviewed and validated by the Chiropractic Head of Course (HOC) and two senior academics in the program and a video (by one of the Senior Lecturers in the Chiropractic course) made available on the unit Moodle site this term to highlight the relevance of the content to their clinical practice and professional development within the Chiropractic profession.
Continue with the provision of the video by the Chiropractic academic and investigate further options to emphasis to the Chiropractic students about the relevance of the content to clinical practice and professional development within the Chiropractic profession.
Feedback from Unit Coordinator reflection Informal communication with students
Provision of a model response to an explanation question for students to critique during most of the weekly tutorials supported students in unpacking the question requirements and understanding how marks are allocated to these question types.
Maintain the provision of a model response to an explanation question for students to critique during the weekly tutorials so that students can practice how to unpack question requirements and better understand the marking criteria for explanation questions.
Feedback from Unit Coordinator reflection
Individialised feedback accompanied with a global feedback video outlining the target response, common errors and aspects that were done well for each assessment type encouraged quicker marking turnaround time and also led to less queries from the students.
Continue with the provision of individualised feedback accompanied with a global feedback video outlining the target response, common errors and aspects that were done well to support quicker marking turnaround time and timely student feedback.
Feedback from Unit Coordinator reflection Informal communication with students

3 Online Test
This test is 90 mins in duration. This time factors in perusal and planning time as well as writing time. The time allowed will provide adequate time to plan and type your answers, plus any potential lag of internet services.
This is a Moodle quiz. You will have a 120 mins window of access to the test (between 9:00 am - 11:00 am AEST).. Once you access the test, you will have 90 minutes to complete it. You are given a single attempt, which means you cannot re-open the quiz once you have closed it. The stated due date/time is when the test availability will close in Moodle, so plan to start your test at least 90 minutes before that time. If you start your test less than 90 minutes prior to the due date/time, your test will still close at the 11:00 am.
If you have an approved extension, you will be assigned a new test date and time as soon as possible after the original test date. It is your responsibility to ensure that you are available at that new assigned date/time.

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.
Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.
When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.
Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.
As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.
What is a breach of academic integrity?
A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.
Why is academic integrity important?
A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.
Where can I get assistance?
For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
