I got an email last week from somebody that had done very poorly in high school chemistry and wanted to go back and teach themselves chemistry. They asked me for advice on subjects that they should brush up on, and then a good resource for teaching themselves chemistry.
I've said more than once before that the first time I learned chemistry (in college - I did terribly in high school) I did so because I had a lousy professor. In fact, because this professor was so lousy, I was forced to teach myself chemistry rather than rely on his explanations.
However, this is not to say that this professor didn't give me anything at all. Though I didn't attend classes, the pacing of the class gave me some idea of how fast I should be learning. Additionally, the amount of time spent on each topic in the syllabus told me which topics should be given greater emphasis in my studies. Without even attending a class, I had a pretty good idea of what I should be studying, and how fast.
I also found that the exams, though unpleasant, provided that bit of accountability needed to keep me on track with my education. Without these exams, I would have had no real driving force to keep learning - I could have put off my studies without consequences, or even skipped the parts of chemistry that I found boring.
So, what does a chemistry teacher do? Minimally, even the worst teacher does the following:
- They let you know what you need to know.
- They let you know how fast you should learn it.
Of course, a good chemistry teacher does a lot more than this. A good teacher should be able to help cram that information into your head and should make it entertaining whenever possible. A good teacher should be accessible enough that you can get help if you need it, and friendly enough that you don't feel uncomfortable doing so.
However, for those of you who don't like your teachers, don't tell me that it's impossible to learn anything from them. I know from experience that even the most useless teachers make it possible for you to learn, provided you've got the needed motivation.
