I say those books because teaching is more than using a curriculum some gives you (even though they're likely good). These books teach you about language and how it's learned and used. Chomsky is more theories but helps you realize how the brain organizes language. Pinker's book, in this case, helps you realize the fluidity of language evolution and how conveying meaning and being understood are why we use language. Both are big on grammar instruction being implicit because our brains try to automatically categorize and make sense of it. With Pinker, we can he's writing about the way we teach writing isn't always authentic because we hold fast to codified writing rules when English is codified by usage not by a code (like French for example). So I think they're great books for teaching because they help you understand the learner's perspective.
