This is info about Chomsky and his Langauge Acquisition Device
http://www.chomsky.info/bios/2001----02.htm
Chomsky came up with LAD, an innate linguistic structure in the brain, based on observations that children universally pick up on language without formal instruction. This contradicted the prevailing behaviorist theory at the time which states that a person is a blank slate, learning anything as s/he gains experience. His LAD theory gained quite a lot of traction, and remained for almost 50 years. He's since rejected his own theory in favor of another of his theories, the Universal Grammar theory which states that the ability to learn grammar is hardwired in the brain. UG does have scientific evidence to support it based on neuroimaging while LAD has yet to show anything.
To contradict the LAD, there have been case studies about individuals who never acquired language, those who were born deaf and never interacted with others who knew sign language. They also didn't know they were deaf. These people never developed language. Instead, they used mime. What would normally take a deaf or hearing person to sign or speak in few seconds, it took these non-language people 45 minutes to mime.
Here's a podcast from RadioLab, "Words", which is about language and mentions these deaf people.

According to
Techniques and Principles in Langauge Teaching, 2e by Diane Larsen-Freeman, there are multiple methods of language teaching such as Grammar-Translation, Direct Method, Audio-Lingual, the "Silent Way", "Dussuggestopedia, Community Langauge Learning, Total Physical Response, etc. This book describes these various approaches to teaching language. However, all of these methods ignore one crucial point: how people actually learn language.
According to this article, language learning is iconic.

This follows direct/indirect associations of classical learning theory.
The point about these methodologies is that it totally focusses on the role of the teacher. Somehow, the knowledge of the teacher can be transferred to the students through direct instruction. If the goal is for students to learn to speak in a language, this goal can easily be met. ("Bonjour, je m'appelle Solcielo.") But if the goal is for them to
communicate using that language, then there is a huge failing. ("Sorry, I don't speak French, just English.") Why is that?
Because language learning falls within the social domain; it's a direct consequence of social learning. Albert Bandura stated that children observe the environment around them, pick up cues, and imitate them. This work was seminal in the area of child development because it went against the grain at the time and suggested that children learn from interacting with others, both other children and adults. If you think about this, then all those methodologies where the teacher instructs just won't work because that's not how language learning takes place. Langauge is learned through interactions with others who already hold that language. This is why a person with English speaking parents, growing up in France, learns French and speaks English
without a French accent. Whereas his/her French peers who do learn English do so with a French accent.
One more request: will you also please elaborate on your conjecture that "All theories of language learning are faulty in this regard..."? Maybe you could cite some alternate language learning theories that work better.
Sorry, I meant all
methods of language learning do not work.
