BioAudio
Welcome to BioAudio: The Teaching Podcast. After many years teaching biology in universities in the UK and in Canada I've come to the conclusion that we can do better than text books. I always want something more flexible, that can be updated with new topics and new discoveries. After years avoiding textbooks… I've created BioAudio a collection of discussions to accompany lectures in university biology courses . So let's ditch the textbook and just listen.
