Earlier quoted context omitted.

The trouble with organic chemistry is that it's a lot harder than inorganic chemistry precisely because of the near-infinite complexities of organic molecules. If you want to teach people the basics, such as how to identify a sample or how to perform analytic chemistry (for example, work out how much of a compound you have got in a volume of solvent), you really have to start with inorganic chemistry.

On the other hand, understanding molecular bonding is much easier in organic chemistry. Inorganic chemistry mostly requires molecule-by-molecule computational solutions, whereas organic can get you quite far purely with rules of thumb. I majored in chemistry, and it was widely accepted that inorganic chemistry was "harder" because of the above.

My experience is exactly the opposite. Inorganic chemistry is mostly governed by the valencies of the elements reacting (and thermodynamics, of course) which are easily learned. Whereas organic chemistry is enormously complicated by the sizes and shapes of the molecules.

Organic chemistry is the bomb. I was bored to death with inorganic chemistry, maybe because of the way it was presented, but organic chemistry seemed like suddenly being shown that all the cool stuff in the world is made of lego pieces (carbon atoms), and there's a manual for how to put them together in different ways. I wasn't exposed to it until university, but I always thought the material would make a good intro…

I think it all comes down to the instructor. I took Organic the 1st time with a semi-famous professor who didn't want to be there and just sat next to an overhead projector and wrote down formulas for us to memorize. Boring! I squeaked by with a C. When I had to take it again for grad school because I failed the organic part of the entrance exams (imagine that) I had a completely different experience. The instructor obviously loved to teach and she taught us the principals as to why A+B=C rather than just memorizing. I loved that class and got an A.

I was bored of chemistry until I started cheating on tests. Somehow creating my own system to represent all those reactions so I can cram all of them in 3pt font on a 3x1cm piece of paper has gotten me sufficiently interested that at some point I realised I've learnt it.

> Students are given incredibly precise instructions and told to find a certain result. If they fail to find the result, they are made to redo the “experiment”.

In my final Chemical Engineering Unit Operations lab course there was a distillation column with the associated instrumentation suffering from neglect and abuse, as indicated by the saw-tooth molar ratio across the height instead of the smooth curve one would expect. My teammates for this lab insisted that we just fake up good-looking data for the distillation column to put in our report because that's what the other teams were doing. I put my foot down and told the team that we would use the data that was recorded, and draw conclusions in the lab report about the poorly-maintained equipment, and maybe something would be done about it before the next semester.

Well sonuvabitch... We received the only passing grade on that particular unit op lab, and the department chair allocated money to refit the lab equipment.

When learning, it's not about the result as much as it is getting the process right, something from which the standardized curriculum and test culture has steered education away.

Well, I learned chemistry (UK O-level and A-level) about 50 years ago, and back then you could do almost anything you fancied with the reagents available, which did stop short of things like fluorine, but only just. Did you know you can dip your (dry) fingers into concentrated sulphuric acid and only experience a feeling of warmth, as the acid reacts with the oils of your skin? As to what we got up to with metallic s…

> fingers into concentrated sulphuric acid

You might want to wash your fingers under a lot of cold water after that :)

Certainly, don't pick your nose :)

No offense to the author, but it might be poor teachers.

My high school chemistry teacher was one of the best I've ever had. She made it very fun, and had a stream of kids taking her classes and ultimately getting 4s and 5s on the AP chemistry test. It was so much fun I spent a semester as her lab assistant.

You can replace chemistry with math in his article (and he sort of mentions this in context near the end). I can't remember once being shown the physical problems that drove progress in math until I reached calculus. I remember being bored to tears in algebra 2, a class which was basically being taught as linear algebra + trigonometry. It wasn't until the following summer that I discovered 3d transforms, and a bunch of other applications of all that matrix manipulation and how all the sin/cos manipulation helped with RF electronics.

Back 25 years ago I was convinced that that entire class could have been taught as an extension of more concrete subjects (electronics, computer graphics, signals, etc) that simply weren't taught in the high school I went to, despite the fact it was what we now call a STEM magnet school. Classes I later wished I could retake, if only to pick up on all the math subtleties I mostly ignored because it all seemed so pointless.

Now that I have kids, I see that nothing has really changed. Sure they get a lot of "word problems", but the problems are so artificial they might just be worded as "what is the result of adding A and B and dividing by C" for all the natural concepts they get across.

Thankfully I had a pretty reasonable chemistry teacher, who did a lot of demos and gave us interresting experiments to keep the class from being a bunch of random facts.

Me too: my high school chemistry course was one of the best courses I ever took including H.S./college/medical school. Hard and wonderful. FunFact: I too spent a semester as chemistry lab assistant in lieu of a study hall.

Introductory chemistry that would be interesting would trend towards the expensive and the dangerous. I'm not sure how you fix that - high schools are not going to be letting kids do metallurgy or create black powder fireworks, so you are going to be stuck with the mostly pointless and very boring lab work.

"Interesting" doesn't have to mean "spectacle". Getting a few droplets of water out of a burning candle isn't riveting to watch but its still very interesting.
