English language teaching in elementarγ school was proposed and is now in practice on the basis of the Critical Period Hypothesis which is also theoretically supported by innatists who argue that UG begins attrition around puberty and that language acquisition becomes increasingly difficult beyond this period. This was proved true of first language acquisition and naturalistic SLA, but no evidence has been known about instructed second language leaming in formal education. Elementary school ELT is supported by some parents who wish their children to leam this world language effectively, but the educational environment is far from utilizing the leamers' UG: few teachers are capable of providing authentic input, so the leamers depend on their general intelligence and leaming strategy rather than UG. It is suggested that high school age is optimum for utilizing leamers' motivation, intelligence, and leaming strategy.
