This past July I had the pleasure of visiting rural Robertson County School District in Tennessee to conduct a day-long teacher training session to introduce intermediate through high school teachers to science, technology, engineering, and math (STEM) practices and content. The first part of the day focused on introducing teachers to the 4Cs of STEM education: critical thinking, creativity, communication, and collaboration. Additionally, teachers were introduced to the Engineering Design Process through mini engineering design challenges, materials science, and reverse engineering. During the afternoon session, teachers were given a couple of engineering design challenges to undertake including designing, building, and testing a vehicle that would be moved by air using a balloon and recycled materials. Teachers used journals throughout the day to record their observations, questions, data, and drawings. Lastly, teachers were introduced to incorporating technology into their STEM lessons, aside from the use of computers such as: digital scales, digital calipers, mini illuminated microscopes, and more. As always, this was a great group of teachers who left the training with a better understanding of STEM practices and content entails. The following photos were taken during the day-long STEM teacher training session.
