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 SUTE Teacher Evaluations
Some students found that it was difficult to remain engaged during tutorials, as Physics is quite dense.
Construct online quizzes such as Kahoot during tutorials to encourage interaction and engagement.
Feedback from MEDS12001 Q&A forum
Some of the older lectures have poor audio quality and are blurry when using different platforms.
Replace older lectures as the audio tends to distort when the volume is too high.
Feedback from MEDS12001 Q&A forum
The final Lab session is too rushed.
Some content from Lab 3 can be transferred to Lab 2.

The unit coordinator for MEDS12001 is Deanna Armstrong. Deanna is based on the Sydney campus, Monday to Friday. The best way to contact Deanna is via the Q and A forum on the Moodle site. It is important to check the Q and A forum regularly for updates and information about the unit.
If the matter is of a more personal nature email Deanna at d.armstrong@cqu.edu.au ensuring that all email correspondence is via your CQU student email.
Discussions about unit content and assessment are provided in the tutorials. Tutorials are held on Wednesdays at 2:00pm AEST as per the above term schedule. The schedule, links and tutorial recordings are available in the Virtual Classes tile of the Moodle site.
There are three (3) on campus labs to attend during the term in weeks 1, 5 and 10 respectively. Students are expected to perform the tasks set out in their lab manual and answer the relevant questions.
It is highly recommended that students attend these labs as the lab manual submission is a PASS/FAIL assessment of this unit. Failure to submit the lab manual by the due date will result in failing the unit irrespective of student's achievements in other unit assessments.
No replacement labs will be available for students who fail to attend a lab for any reason.
1 Online Quiz(zes)
You will complete an online quiz to assess your understanding of the concepts delivered in week 1 to week 5 of MEDS12001. The quiz can be accessed through the assessment tab on Moodle.
The online quiz is open from 6:00 am AEST Thursday of Week 6 to 11:00 pm AEST Friday of Week 6.
The questions will be a combination of multiple choice, true or false, gap-fill and drop down selection questions.
Only one quiz attempt is allowed and it cannot be paused or restarted.
Questions will be randomly drawn from a large pool of questions to allow the quiz to be different for each student.
This assessment is to be undertaken as an individual. As with all other university assessments, colluding with other students on non-group work tasks is considered academic misconduct, and may lead to academic penalty.

Physics laboratories (labs) will provide an opportunity for you to explore the principles of ultrasound physics and develop knowledge of machine instrumentation and controls under the guidance of a tutor.
In small groups (4-5 people), you will collaboratively perform tasks set out in the lab manual during the practical laboratory sessions (weeks 1, 5 and 10).
During the labs you will work in teams to acquire images and observe the effect of changing machine parameters on the resultant image. Acquired images are to be shared amongst the lab group.
You may complete the lab manual questions during the lab sessions or later in your own time. Lab manual questions are to be answered as an individual.
Upload your completed lab manual to the unit Moodle page via the link provided in the Assessment block.
It is a highly recommended that you attend all the laboratory practical sessions in order to meet the unit learning outcomes.
If you do not attend a lab session for any reason you are still required to complete the lab manual exercises and submit the lab manual by the due date.
Please bring a USB stick to labs to save the acquired images.
Please note the following excerpt from the University Assessment of Coursework Procedures: '...students who fail a single assessment task in a pass-fail unit, or who fail a pass-fail component of a graded unit will be deemed to have failed that unit'.
Week 11 Friday (24 May 2024) 4:30 pm AEST
Review/Exam Week Friday (7 June 2024)
You are required to demonstrate your understanding of each lab task by performing the assigned task and correctly answering the assigned question for each task.
The lab manual questions can be attempted during the lab session, and may be completed in your own time. Questions should be answered concisely and supported by the acquired images where required.
Record and store the acquired images as per instructions in the lab manual. The images are to be stored on a USB drive (provided by the student) and inserted in the lab manual, which should be saved in Microsoft Word format.
This assessment will be marked as a PASS or FAIL. A minimum of fifty percent of the questions must have been answered correctly for students to obtain a PASS grade. A detailed marking rubric is available on unit's Moodle page.
Failure to submit the completed lab manual by the due date and time will result in a grade of "FAIL" for the student regardless of their performance in other assessments of the unit.
There is no option of extension or late submission for the lab manual assessment (unless approved extension is obtained via the Moodle Extension Request System, with appropriate documentation) as students have 10 weeks to complete this task (from week 1 to week 11 of the term).

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.
