I enjoyed the comical view of the past. Expectations have certainly changed. A long time ago in a galaxy far away..... teachers worked in isolation. Now, we meet for professional learning communities weekly. Students were not seen or heard. Now, we are learning to integrate social media, and the global society. Blackboard dust used to fill the air from writing on the board. Now, we have apps in education. Times have certainly changed.
Comical, yes, but all true. You're right, though, many things have changed. But still, teachers go home exhausted! Maybe even more so.180 days a year, 6 hours a day? No way.
