Why ‘WD-40′ Is Not Known As ‘WD-1′
If you’re at all like me, somewhere in your home you have at least one can of WD-40®, because the stuff works wonders. If you teach science, I believe that you ought to have a large WD-40 poster on your classroom wall. Not to advertise the product but to teach a basic lesson about learning: failure is an essential part of succeeding.
You may know the story of WD-40.[1] More than 60 years ago the three employees of the San Diego-based Rocket Chemical Company were trying to develop a product that would prevent rust, something they could market to the aerospace industry. They tried, and, being methodical, they kept careful records. They labeled their first effort Water Displacement #1, or WD-1.
I’ll bet you have figured out how many times they failed before they were finally successful.
Students need to know that adults try and fail and fail and fail–and keep on trying. More than that, they need toexperience failure. While I am a big fan of both project-based learning and blended learning, I believe the most critical piece of the pedagogical puzzle is what we ought to call ‘Problem-based learning.’
Projects where the teachers already know the outcome won’t work, especially with older students. Blending technology and teaching so students can add fractions faster? That’s not the best approach either.
Give students problems to tackle–and make the problems real! Lord knows we have plenty of problems worth tackling that can be given to students. They cannot be intractable (how can we achieve peace in the Middle East?) or trivial and uninteresting (what color should classrooms be painted?)
A pedagogy based on discovery flies in the face of what seems to be happening in most classrooms and schools[2], where the emphasis seems to be on ‘critical analysis’ to get the predetermined answers.
Some years back I interviewed a math teacher in Richmond, Virginia, who told me how he used to take his students down to the James River and challenge them to determine how far it was to the opposite shore. He didn’t give them a formula; just the challenge. Then they put their heads together and, he said, eventually worked it out. Lots of failure…and lots of genuine discovery. Sadly, he said, the new state-mandated curriculum doesn’t Why ‘WD-40′ Is Not Known As ‘WD-1′ | Taking Note:
