2 Practical Assessment
The physics labs will provide an opportunity for the students to explore the physical principles of ultrasound and develop their knowledge of machine instrumentation and controls under the guidance of a tutor.
Students are responsible to print their lab manual and bring to the lab or have access to the lab manual on their electronic devices.
In small groups (3-4 people), students are required to collaboratively perform tasks set out in their laboratory (lab) manuals during the practical laboratory sessions (weeks, 3, 5 and 10) and obtain ultrasound images that will assist to answer set questions per task.
During the labs, students will be required to record and store images, and observe the effect of changing machine parameters on the resultant image.
Students will be required to attempts the lab manual questions during the lab sessions. The questions are designed to help students understand the physical properties of ultrasound and how that knowledge is used to inform the practical production of diagnostic medical images.
Students are expected to work in teams to acquire images. Image sharing within lab group members is permitted.
Students are expected to individually submit the completed lab manual by week 11, Friday 31st of May at 14:00 AEST.
Please note the following excerpt from the University Assessment of Coursework Procedures: '...students who fail a single assessment task in a pass-fail course, or who fail a pass-fail component of a graded course will be deemed to have failed that course'.
Students will be required to upload their completed lab manual answers to the unit Moodle page via the link provided in the assessment block.
It is a highly recommended component of the unit to attend the laboratory practical sessions in order to meet the learning outcomes. Students who fail to attend a lab for any reason, are still required to complete the lab manual exercises and submit the lab manual by the due date.
Students are advised to bring a USB stick to labs to save the acquired images. Image sharing amongst group members is allowed.
Week 11 Friday (31 May 2019) 2:00 pm AEST
The completed lab manual should be submitted as a single Word document on Moodle.
Week 12 Friday (7 June 2019)
The PASS / FAIL grades will be available on Moodle by Friday 7th of June 2019.
Students are required to demonstrate their understanding of each lab task by performing the assigned task correctly and answering the assigned question for each task.
Students are required to record and store the required images as per instructions on the lab manual.
The images are to be stored on a USB drive (provided by the student).
Answering the questions in the lab manual can be attempted during the lab session and may be completed at own time, once the lab activities are completed.
Questions should be answered concisely, supported by the acquired images where required. The acquired images should be inserted in the lab manual which should be saved in the Microsoft Word format.
This assessment will be marked as a PASS or FAIL.
At least fifty percent of the lab activities should have been carried out correctly and the designated questions answered correctly for students to obtain a PASS grade.
Failure to submit the completed lab manual by the due date and time will result in a grade of "FAIL" for the students regardless of their performance in other assessments of the unit.

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.
