Teaching Method 1 - Synchronous teaching sessions weekly using Teams or Zoom to replace lectures, supplemented by provision of asynchronous self-study materials in Canvas
Description: Frontal and recorded E-lectures on VITAL

Notes: Alternate weeks to labs

Teaching Method 2 – Virtual Laboratory Work
Description: Hands-on activity using online simulator
Notes: Alternate weeks
The synchronous teaching sessions, and asynchronous provision of self-study materials, are to replace conventional lectures. Exercises using online simulators are to replace laboratory work whenever possible,
These learning and teaching methods will be used for hybrid delivery, with social distancing on campus, as planned for semester 1. The following changes may be required in response to circumstances:
(b) fully online delivery and assessment, (i.e. if full lockdown is necessary): The on-campus lab work will be stopped and whenever possible replaced by a video or simil ar and provision of pre-prepared datasets and experimental results for analysis and report-writing.
(c) standard on-campus delivery with minimal social distancing: The synchronous Teams/Zoom remote teaching sessions may return to being on-campus lectures
