"capitalist competition makes us stronger and more innovative"

sorry radlibs but there's a reason why 35% of students in your shitty designed STEM classes drop out, they aren't stupid for getting bad grades. You're the stupid one for being so ignorant that you've managed to fail to educate people for over 60 years. I take back everything I said about "western kids want to be Twitch streaming gamers lol they're losers", these families literally have not had access to a decent science education for three generations!

Are we still persisting in making our students sick of chemistry because “that is how chemistry is done here”? Who set the scene? How did it all come about?

The answer lies not with some malevolent group of people, but with a response made in the 1960s in the United States and throughout the Western world to combat the perceived threat of Russian scientific supremacy. ChemStudy and Chemical Bond Approach sprang up in the United States, Scottish Alternative Chemistry and Nuffield Chemistry appeared in the UK, and similar schemes were launched

his suggestions for improved chem curriculum

Begin with the idea of the filter that is driven by what the learners already know and by what interests them. There is no point in beginning a course in chemistry with a treatment of atomic electronic configuration or bonding because the anchorages in long-term memory are not there. Without attachments in long-term memory, a student can only learn by rote methods. An approach to chemistry through acids, bases, and salts is unlikely to stir students with enthusiasm. Apart from common table salt, how many salts are in place in long-term memory to provide relevance and reality for the learner? On the face of it, inorganic compounds are “simple”, but are they? So many wrong concepts are introduced by teachers or constructed by the learners in this area of chemistry. A glance at a book of chemical data will show the absurdity of suggesting that sodium (or any other metal) is “anxious” to lose electrons and chlorine is “desperate” to accept them. It is too soon to introduce lattice energy or hydration energy to provide a rational basis for compound formation. The octet rule, with all its pitfalls for later study, tends to raise its ugly head here as a sort of rationalization.

The model suggests that we should begin where students are, with their interests and experience, and lead them into discovering new ideas among the familiar. An obvious starting point is in organic chemistry, with gasoline, camping gas, food, clothing, plastics, and drinks and so much more that is familiar. I know that it has been the tradition to keep organic for later, but are we taking a “monkey” point of view? Let us consider some of the advantages in starting here.

The long-term memory already contains anchorages for what we want to teach and the filter is primed and ready to go. The working memory is not in danger of overload. We can go a long way into organic chemistry with only a few elements: carbon, hydrogen, oxygen, nitrogen, and possibly sulfur and phosphorus. Most of these are familiar (at least their names are) to the learner. By considering the spatial arrangement of the four electrons around a carbon, students, using their fingers, can see that a tetrahedral arrangement is likely. Never mind sp3 hybridization. It is a cobbling together of atomic orbitals (isolated atoms in the gas state) to produce a tetrahedron. This is using unreality to arrive at reality. Pasteur knew about the tetrahedral arrangement long before atomic orbitals were conceived.

Using the simple tetrahedral idea, we can do a lot of sound organic chemistry linked to what the students already know, avoiding overload of working memory. Only when we reach organic acids do we have to reconsider bonding, but this can now be linked to the simpler ideas of covalent bonding already established. Another advantage of beginning with organic is that there is no pressure to use balanced equations. Practicing organic chemists do not bother, so why should we?

The model has led us to select a starting point that fits what is already in a student's long-term memory. The working memory is not overloaded because only a few elements are involved in making familiar compounds. The representation triangle can be used along its sides to build ideas of the relationship between the macro and familiar, with the molecular. The use of the representational is reduced, and no calculations are necessary. All of this provides a logical basis for an applications-led approach instead of a conceptual approach followed by a passing mention of uses and applications.

The troublesome mole can be rethought in the light of the model. It has been my sad experience to have graduate students who confessed their inability to do mole calculations. The very word “mole” left them uncomfortable. How could highly intelligent young people have such an aversion? They met the mole too soon, wrapped up in incomprehensible (and even totally irrelevant) calculations that flooded the working memory into a state of paralysis. In an earlier publication (4) I set out an analysis of a trivial (from my point of view) mole calculation. I saw it as a four-step procedure, which did not tax my working memory, because I already had tricks for grouping the processes, but students saw it as a ten-step task, which blew their working memory.

    Starting with orgo without fundamentally changing how orgo is taught too is a terrible idea

    On my first day of orgo 1 in undergrad my professor said "Everyone raise your hand. Put your hand down if you're not a chemistry major." all but 10-15 people put their hands down "Now put your hand down if you don't plan to go to grad school specifically for organic chemistry" all but 2 people put their hands down "If you are not one of those two people who still have their hands up, you will never use a single thing you use in this class."

    And he was 100% right and yet still made that class harder than it needed to be. This is deliberate of course, organic chemistry isn't used as an academic class where skills and knowledge are taught, but a barrier to prevent too many people from going to med school.

      My reading of the paper was different. The author isn't suggesting teaching ochem but rather using organic molecules as the route to teach basic chemical concepts.

        Yeah sorry kinda got distracted from the main point by just getting mad at my old orgo professor

        God I hated that man, he’s the only non-politician I’ve ever genuinely wished death upon. Easily the worst teacher I’ve ever had, and it makes me feel a deep rage and disgust that he gets to have this highly valued position instead of someone more deserving. I would say he should be forced into sanitation work, but I don’t think the heroes who do that work should be forced to work with this man. But if there’s anyone who deserves to be paid like shit to clean up other people’s shit it’s him.

        The main point of “we teach chemistry bad” I fully agree with

      Don’t we already have a doctor shortage?

      What the heck are you guys teaching in organic chem that doesn't have wide application in molecular biology, biotech, etc? Quantum chemistry of exotic organo-metallic complexes? Here organic chem is considered much, much easier than physical chemistry (2nd year inorganic chem).

        We do General Chemistry 1 and 2, then Organic 1 and 2, then Physical and Inorganic you only take if you’re like, a chemist or a material engineer.

        General covers ionic compounds, basic bonding mechanisms, acid-base and electrochemistry, shit like that. It’s mostly a math class with some theory about molecular bonding. Organic is just rote memorization of very detailed reaction mechanisms. I work in a biology lab and I use the stuff I learned in Gen chem daily and have never used even a concept from orgo. Orgo isn’t treated like a class here, it’s just an obstacle for pre-med students.

          That seems...dumb...especially since most organic reactions you can just vibe from first principles or learn by osmosis and the more obscure ones just look up in a book. Far more important to learn practical organic synthesis and characterisation techniques, along with an intuitive understanding or organic structures.

      One of my bros went for a chem masters, and he would frequently end up staying up spending half the night studying for orgo. It was to the point that the stress would get so out of hand it would overstimulate him and he would need to run to the bathroom to vomit, and then he would go back to contunue studying
