Dr. Laura Pasquini is an educational coach and consultant who is passionate about podcasts. She has created two resources that may be useful to you if you are interested in finding more educational podcasts to listen to, or creating your own:
HigherEd Podcasts: https://bit.ly/higheredpodcasts is a spreadsheet that she has curated. The first page has a list of more than 200 podcasts that focus on various aspects of higher education. The second page is a more general list of podcasts that touch on more random topics in the range of education, general interest and self-improvement.
Behind the Podcast: http://bit.ly/behindthepodcast provides a behind the scenes look at how some of the more popular higher education podcasts are created recording set-ups of several higher ed podcasts. The producers of podcasts such as Teaching in Higher Ed and Thinkudl.org share information about the hardware and software they use to create their podcasts, as well as their hosting service and resources they use to produce the content for their podcasts.
