When I was in graduate school, I spent three months attempted to make a certain type of reaction happen. I tried changing everything, but the idea that worked in theory didn’t seem to happen in reality. Then while searching in the chemistry library, I found a twenty year old article in German that mentioned the reaction. After getting it translated, I found that it wasn’t going to work the way I hoped and the last three months were wasted. If only I had known.
In science, the vast majority of articles describe things that work. Almost all of the dead ends and failures go unpublished. There is a lot of wasted work researching ideas others have tried before. I feel that this is true into teaching too.
When I first started blogging it was intimidating! I only wanted to show fully developed successful ideas. I was embarrassed to share what tried and failed. But that has a lot of value too!
