Nucleus Learning

There is a steady increase in environmental issues in the curriculum every year. The environment is important and we must take care of it, thus teaching about it to students that will one day take care of the world is a necessity.

But whenever I learned about it or taught it, I found it to be more of a “social studies” subject and not a science. There’s a lot of descriptions, definitions of concepts, discussions of alternatives, debates. It never felt like a real “science”, with numbers, predictions, experiments, etc. I know that this is not the case. I know that environmental sciences are very much scientifically based and hard core, with lots of experiments and empirical data supporting phenomena, but the way the curriculum has the “environment” presented wasn’t at all interesting to me thus far (since I’m one of those science geeks).

A while back I was in a situation where I had to teach evolution to some grade nine students. I am more of the physical science/math teacher, and biology is not my cup of tea.

In physics, there are also unproven “theories” that we follow. In fact, all of Newtonian physics is pretty much “false” and yet we teach it all the time as fundamental physics. Light is both a wave and a particle… how can that ever be possible? Either it can travel through objects (like a wave / energy) or it is stopped by objects (like a particle)? For some reason, the physical theories don’t affect people in the same emotional way as the theory of evolution. We have a way of dealing with the physics theories on a logic / thinking level. No religion is offended (although ~400 years ago, Copernicus’ theory of planetary motion around the sun was dissputed by the Catholic church). Nobody’s extreme beliefs come under fire with all these silly physics theories.

Recently I taught my son (grade 2) how to do subtraction of large numbers with borrowing. I am a high school math teacher, so I thought that teaching this subject would be a piece of cake. However, I didn’t realize that I would have to be this creative in order to actually get through to my son. Anyway, my method worked like a charm, so I’m posting it. It’s pretty basic, and I’m sure it has been widely used by good teachers (that really understand how to teach kids math), but in case you haven’t thought of this method, here it is.
