A YouTube video promoting Iowa Governor Terry Branstad's STEM initiative features 2015 Northwestern College graduate Tyler Robyn. Robyn participated in a teaching externship at a machine shop which helped him better understand how math applies in the real world and equip him to explain concepts to his students. As a member of the governor's STEM Advisory Council, Robyn hopes externships can raise awareness of STEM careers and their importance to the state's workforce and economy.
