BMSC12009 - Sleep Physiology and Measurement

General Information

Unit Synopsis

This unit enables students to relate diagnostic monitoring of sleep behaviour across the lifespan via polysomnography to sleep physiology and specific sleep disorder groups. Common causes and treatments for sleep disordered breathing, insomnia, hypersomnia and sleep related movement disorders will be investigated.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 20%
2. Group Discussion 40%
3. Online Test 40%

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%).

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.

Source: Unit evaluation and student emails.
Some students felt that there should be a greater proportion of marks assigned to the group work component of Assessment 2.
Review the weightings of the individual components assigned to Assessment 2 (Group Work task) to better reflect the group work component.
Action Taken
Weightings were adjusted for Part A (individual component) and Part B (Group work component) of Assessment 2.
Source: Unit evaluation
Students enjoying having weekly lectures and fortnightly tutorials.
Tutorials will continue to be held fortnightly to support the weekly lectures.
Action Taken
Fortnightly tutorials were maintained for the 2023 offering.
Source: Self-reflection
The inclusion of a weekly worksheet or quiz would further support students to assess their knowledge
A worksheet will be created for each week to allow students to test their understanding of the content and provide an additional source of revision.
Action Taken
Rather than providing students with a weekly worksheet. Regular activities were included during the recorded lectures and tutorials to promote active learning and student engagement.
Source: Verbal student feedback
Students enjoyed the use of Moodle lessons to deliver interactive lectures
The use of Moodle Lessons for the delivery of lecture content will be maintained.
Action Taken
Source: Unit coordinator reflection
The weighting of assessment item 1 is not reflective of student workload.
The potential of increasing the weighting of assessment item 1 will be investigated.
