Give an elementary school or junior high student a box filled with Bill Nye The Science Guy videos and they'll remember how each experiment worked. Read it aloud in class, fill out a worksheet, and take a test, and only a small percentage of children will remember the correct answers. Chances are that even the brightest children will only have a vague recollection a month later. Teach a child about combustion and pneumatics by having them construct a spud gun and then pitting them against each other in teams like little combat warriors on the playground and chances are they'll remember one thing from science class that year - how to build a spud gun.
If you're like me, you don't need statistics or high-level research to convince you that humor is one of the most effective tools we can use to create unforgettable learning experiences. In fact, my best teachers taught me with School House Rock videos. As a Generation X learner, I appreciate a good animated educational short over a lengthy documentary any day. Take this video on Where Good Ideas Come From by Steven Johnson. Is it just me or are the comics a really good idea? I could learn anything if you deliver it in a comic book.
