Chalk talks included in this section can be replicated in 30-45 min or can be used for self-directed learning. Most talks will require at least 10 -15 min of preparation to familiarize yourself with the topic and background information. Some chalk talks are specifically designed to be replicated on a chalk or whiteboard. However, for all talks, the website itself can be used as the teaching platform. Teaching instructions/script and additional teaching information can be found most commonly by clicking on the board diagrams.
