This is a speech given at a large "back to school rally" held by the Dallas ISD. Many districts around the nation are using it as the school year opens.
The speech DOES help focus us on the reasons why we are teachers, and our purpose in the classroom. Which is directly at odds with much legislation, and with many federal, state, and often district mandates.
Inspirational speeches are great when the nuts and bolts of action are behind them. Hypocritical when they contradict established policy.
Dalton says he "wants to be the next Obama." I can see that; he's well on his way, lol.
He did not write this speech. It was written by the Dallas ISD. He has quite a bit of experience in public speaking. He's not just a random pick out of a classroom in the district, lol. Still, it's enjoyable to watch. It IS inspirational. Here's a link to a news article about him:
