Many staff involved in teaching, learning and assessment already engage with the principles of UDL in their practice, as much of the guidance around UDL relates closely to simply good teaching, learning and assessment. The first component of the toolkit is an introduction to UDL, which aims to introduce staff to the concept of UDL and how the principles connect with their existing practice. We designed this introduction using H5P, an open source content creation tool, allowing us to draw on the rich range of multi-media resources already available in relation to UDL, from organisations such as CAST in the US and AHEAD in Ireland. The introduction to UDL is available below, and is also available in Google Slide format.
