Guest post by Henry Thiele, Superintendent, District 99 (IL): Today is Valentine's Day, and an interesting fact about this holiday is teachers receive more Valentine's Day cards than anyone else (opens in new tab). I find this to be an interesting data point, because it illustrates the number of connections teachers have with society each day. It is a great opportunity for us to reflect on the impact teaching has on the lives of so many and the importance of our work. Use this day as a reminder of how the relationships we build, and the outreach we offer, builds our credibility in the eyes of our students and lifts up our profession. The world is more connected than ever, but Valentines Day provides the evidence that teachers are at the heart of it all.
