Ellwein has been a principal for eight years but has always had a passion for technology. He believes technology has the transformational potential for growth in learning, for teachers and students. He has made sure every staff member at Harrisburg South Middle School (HSMS) has a Twitter account which has allowed them to communicate with parents through the social media network. In addition to social media, Google Docs and Google Hangouts have played a major role throughout his school. Ellwein has also created technology-based clubs such as the Drone Club and has even created Twitter Tuesdays and a Genius Hour every Wednesday which has led to the school’s Makerspace being used for prototyping inventions such as an automated dog feeder.
