Dr. Eric Langhorst teaches 8th grade American History, broadcasting and technology at Discovery Middle School in Liberty , Missouri. I found some valuable information on his website. Dr. Langhorst started a vlog called, "The History Geek Teacher" as a platform to share ideas related to education, technology and history. He also shares his open educational resources on his website. He shares a Google doc to show the workflow of how teachers are using technology to provide feedback to students. He also presents youtube videos that can be useful to teachers who are wanting to implement technology into their classroom. Dr. Eric Langhorst can be contacted by twitter.
