Last week I was a substitute teacher at a school. I saw this poster on the wall and it had me thinking. I started asking students to connect what they were learning in class to their world. Most laughed. Some said I’m just here for a grade. Many stayed silent. I started making the connections with them. They were actually engaged. That’s when I realized the power of Tech Sparks. How much more powerful classrooms across America will be once teachers get their hands on these bell ringers and PDs! I appreciate each of you for being here!
