Swinburne University provide a great resource on their website called the Design Perspectives Lecture Series. These lectures are a great resource for the design classroom as they would encourage design discussions and introduce secondary students to the inspiration that can be gained from a dynamic lecture on various aspects of design.
Some are accessible only as audio, and could be played in the background while students were working away on their folio pieces. Others are either in video format or as a PDF.
