Here are three TED talks that provide lots of inspiration and food for thought!
First an interesting talk by David Weston - Unleashing Greatness in Teachers - outlines how developing great teachers can change the world.
Next, I Love Teaching So Much ... I Quit is an inspiring story from Tawana Weicker in which she tells how she "learned how to transform waste into biofuel while at the same time identifying the enormous waste of knowledge, creativity and expertise that too often happens in our classrooms".
Finally, in Teachers as Change Agents, Karl Lindgren-Streicher provides ideas for how we can fix 'this broken system' that is education today. He says, "As a teacher, don’t be afraid to take risks and act in the best interests of our students regardless of what the powers that be tell you to do. You CAN be a change agent. Even if you are ‘just’ a teacher!" And he talks about you can find the courage to do this. He also says "when kids know that they're heard, when they know they are impacting on instruction, they'll roll with you."
