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.

Term Specific Information

This unit is delivered across three campuses by a cross-disciplinary team to provide expertise from both the radiographic and chiropractic perspectives. You are provided with a set of learning goals for each week's topics to communicate the breadth and depth of the knowledge and skills you are required to demonstrate in the unit assessments. Lectures are provided as pre-recorded videos via the unit Moodle site. You will have weekly face to face tutorials from Weeks 2 - 12. The tutorials are your opportunity to check your understanding of the content from the previous week as you apply and integrate the concepts with guidance from your instructor. In Weeks 3 and 11 additional tutorials are provided by the unit coordinator for students at all campuses to discuss strategies for demonstrating your knowledge and skills on the in-class tests.

The textbook for this year has been changed relative to last year, but because many students may have access to last year's textbook (Limited Radiography by F. Campeau), suggested readings from last year's text will be posted on the unit Moodle site.

Assessment Tasks

1 In-class Test(s)

Assessment Title
In-Class Test 1

Task Description

You will write an in-class test to demonstrate your ability to apply the concepts and use the terminology from Weeks 1 - 5 of the unit. All questions will be based on the posted weekly learning goals for those weeks. Question tasks will be of the same types that you will practice in tutorials. These question tasks will include analysis of projected diagrams, photographs and radiographs, creation of line diagrams to illustrate concepts, explanations, definitions and discussions. Any projected visuals (diagrams, photographs and/or radiographs) will also be printed onto the test paper in low resolution. You will need to ensure that you can see the projected visuals during the test.

This test is a closed-book assessment of 105 minutes (1 3/4 hour) duration. You will have a five minute settling in period and 10 minute perusal time prior to the allotted writing time. You will write the test under examinations conditions as detailed in the Assessment Procedures. You will hand in your test paper and rough paper at the end of the test period.

This test must be written at the timetabled date and time. As per the University's Assessment Procedures, there is no provision for a late submission and no late penalty can be applied. In the absence of an approved extension, you cannot complete this assessment at a later time, and you will receive a mark of zero for the assessment if you have not completed it by the scheduled date and time.

Academic Integrity Statement

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.
