chemistry: what sticks and why

Did the chemistry teacher do something or, perhaps, did you? What was different about helium from the "massive amounts of material ... not retained after either the course or evaluation are completed"? Could that time be better spent in other ways in chemistry courses? If not, why not? If so, why isn't it? What's the relation between that and a disinclination to entertain a "diversity of problem solving strategies"?
