Reddit mentions of Constructing a Language: A Usage-Based Theory of Language Acquisition

All these have a strong criticism of Chomsky woven through the book:

Foundations of Language, Ray Jackendoff

From Grammar to Science, Victor Yngve

Constructing Language: A Usage Based Theory of Language Acquisition, by Michael Tomasello

Those three will get you started, I have some for Logic and General Linguistics, and will post them when I have the time.

I recently got into a discussion about a high-level issue concerning UG. The case I make is circumstantial but is a counterbalance to all the propaganda about 'science' that Chomskians use to imply that other approaches are 'unscientific'.

If construction grammar is interesting, you might try looking into exemplar theory too. Most of what I'm familiar with in the framework is morphophonology, but there's some stuff on syntax too.

Also, you might be interested in Michael Tomasello's book on language acquisition, for a different perspective from what you got in your class.

One name you should definitely be citing a lot is Michael Tomasello: link (from 2005, an overview of the indequacy of Chomskian approaches to language acquisition) and link (from 1995, a critical response to Steven Pinker's pop-Chomskian book "The Language Instinct") and link (from 2004, a brief note on the question of universal grammar's falsifiability), just for starters. Usage-based linguistics is the major counterweight to generative linguistics these days and Tomasello is at the forefront.
