In previous reviews of studies comparing explicit and implicit instruction (Krashen, 1981, 1982, 1999, 2003), the author argued that explicit instruction will show a positive effect only when the following conditions for the use of the conscious Monitor are met: (1) the acquirer consciously knows the rule or the meaning of the item--that is, has…

In this article, Huw Jarvis and Stephen Krashen ask "Is CALL Obsolete?" When the term CALL (Computer-Assisted Language Learning) was introduced in the 1960s, the language education profession knew only about language learning, not language acquisition, and assumed the computer's primary contribution to second language acquisition…

The recent past in language teaching has been dominated by the Skill-Building Hypothesis, the view that we learn language by first learning about it, and then practicing the rules we learned in output. The present is marked by the emergence of the Comprehension Hypothesis, the view that we acquire language when we understand messages, and is also…

Reviews research on the language acquisition of spelling and vocabulary that further supports the Input Hypothesis for language acquisition, demonstrates the role of reading in spelling and vocabulary development, and reveals those research results' inconsistencies with two alternative hypotheses.

Suggests that reading is a powerful source in acquiring language competence. The author argues that children do not enjoy grammar instruction, but love to hear stories and read books that they select on their own. Given the lack of clear evidence for focusing on form, it is concluded that free reading should be an option for immersion children.…

Presents Dr. Kato Lomb's conclusions about language acquisition, which agree with current theory: comprehensible input is central; grammar plays a peripheral role in language development. (Author/CK)

Discusses the comprehensible output (CO) hypothesis, which states that we acquire language when we attempt to transmit a message to a conversation partner, fail, try again, and eventually arrive at the correct form of the utterance. Examines weaknesses of the CO hypothesis in second language acquisition, suggesting that providing more…

Research published in recent years that deals with the Comprehension (Input) Hypothesis is reviewed, and evidence supporting the hypothesis is underlined. The research is from the areas of literacy development, second-language learning, and foreign-language learning and confirms the claim that development of language and literacy operate in much…

Examines the role of "routines" and grammatical patterns in first and second language acquisition by children and adults, specifically with regard to syntactic structures. (Author/AM)
