Details of Learning Activities

A combination of activities will support students learning in this course, such as:


• Face to face and or online lectures to cover theoretical and practical concepts for each topic in the course
• Students will learn to apply their skills and knowledge to work integrated learning (WIL), during simulations and classroom based learning
• Observations of performance in the workplace and industry placement or simulated environment will be a valuable part of your learning experience
• Tutorial activities (individually and in teams) to discuss, debate, critique and consolidate your ideas and extend your understanding around key concepts within specific topics
• Online discussion and activities support you to collaborate with other students in your course and debate and debate and discuss ideas
• Self directed study time to enhance and strengthen your knowledge and understanding of theoretical concepts
• To further facilitate learning, students are strongly encouraged to use a range of communication tools between themselves and their course instructor as well as between themselves and fellow students by using the online learning platform

Overview of Assessment

 

You must demonstrate Performance and Knowledge Evidence of the unit in order to be deemed competent. 
Assessment methods have been designed to measure achievement of each competency in a flexible manner over a range of assessment tasks.
You may be assessed by: 
• Oral or written questioning 
• Oral presentations
• Assignments and projects 
• Direct observation of actual work practice 
• Presentation of a portfolio of evidence which may comprise documents, and/or photographs and/or video and/or audio files 
• Work-based activities 
• Third-party feedback from a work supervisor/employer
Primary assessment involves on-going practical and applied assessment in a clinical workplace or simulated environment such as a supervised student clinic or at a Work Integrated Learning (WIL) placement activity.
