# The Teach Better Podcast

The Teach Better Podcast is a fortnightly series of conversations with teachers about teaching. We talk mostly with faculty in higher education, but will occasionally talk with other teachers too. Your hosts are Doug McKee and Edward O’Neill. We started this podcast to share ideas and build community among folks who care about teaching, and we were interviewed about our project in the Yale News.
