We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I have been teaching adults various psycho-motor skills in healthcare and computers since 1978. I have often been an adult student in that time range myself.
People learn from both mistakes and successes. In the end, we learn from failure (in my opinion, I omit the "humble") only if we also see success.
I was trying to learn to use a compass in the field. This is a tricky operation, trickier than I could master at one bite. It was all the more so because the terrain was very rough. I did, ultimately, hit my marks after much frustration and several mistakes. Hah! you say, this proves the proposition that we learn from mistakes. Hah! I say, shaking off the cactus pieces on my behind, I didn't ultimately learn anything until I succeeded.
I embrace this in my classroom. Students may get lost, but they don't stay lost. I make sure they find out how to hit the mark and I help pull the cactus chunks out of their behinds. Metaphorically, of course.
I remember, when I was sixteen and working construction, being massively berated by a (don't remember his title) project manager for making a mistake. This is vague of course, but he was of the opinion that mistakes should never be made, that one should always be looking ahead to prevent such. If memory serves he was suggesting that one wasn't very smart if they made a mistake. I responded that mistakes were inevitable and that one need learn from them so as not to duplicate them. It became heated, the discussion, so I let him have his way, as I wanted to keep my job and could see that his was not a yielding position.
