If you're talking to me, I'm from Portugal.
I can give you a few examples. For instance
- My chemistry teacher shouted at me for having 0.1 M acetic acid out of the fume hood for too long ( Vinegar is 1M) and when I said that vinegar was
1M she started screaming again and simply wouldn't answer;
- She also said that there are no plastic pasteur pippetes, and she calls them eye droppers;
- She said that lighting an ammonia solution could cause an explosion of burning ammonia;
You may think that this is an isolated case, but I know another teacher who said chlorine doesn't react with water and another one who couldn't
explain sodium's reaction with water... |
At lower grades, a chemistry or science teacher is expected to have a teaching degree. They are not required or even expected to have a degree in, or
any expertise in science or chemistry. The school administration will just make do with the teachers they have, and if the regular gym teacher is
short of few hours on his workload, and they need someone to teach chemistry, guess who gets the job? My grade 9 science teacher took the job
expecting to teach phys ed most of the time (but this meant that he was comfortable admitting that he wasn't an expert, and if he wasn't sure about
something, he'd often ask me). My grade 10 chemistry teacher did have some education in chemistry, but was hospitalized part-way through September,
and was replaced by someone who had no idea what she was talking about. We argued about whether combustion produced liquid water or water vapour, and
she tried to prove herself right by lighting a candle, and pointing out the melted wax at the base of the flame, claiming that it was the liquid water
being produced. |
