I recently completed a class on Learner's Edge . The class was over the STEM Shift. The price was right and the class flexible. I earned college credit for $200 less than other options I found online. I highly recommend it if you need extra CEUs, like I did. Other and free online resources I have found are through: EdPuzzle (under "Resources") Learning for Justice What tools do you use to earn CEUs?
I'm just a science teacher sitting at my computer generating and finding ideas to make learning more enjoyable.
