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
