In Krashen's theory of second-language acquisition he claims that there is distinction between language acquisition and language learning, a distinction which other second-language acquisition researchers have called "perhaps the most important conceptualization" in the field and which has made possible the most productive models of SLA.…

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…

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 the late 1970s and early 1980s, Stephen Krashen developed Monitor Theory--a group of hypotheses explaining second language acquisition with implications for language teaching. As the L2 scholarly community began considering what requirements theories should meet, Monitor Theory was widely criticized and dismissed, along with its teaching…

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…

Stephen Krashen has a long and enduring legacy in the field of second language acquisition. His "Input Hypothesis" was among the very first attempts to create a coherent theoretical account of second language learning. Krashen argued that learners can acquire language through the process of comprehending it. While elements of his model…

Stephen Krashen's theories can appear "seductive" to teachers of languages, in that they identify a seemingly clear way forward for language acquisition in the classroom. However, reification of Krashen's theories, in particular the notion of attaining "i+1" through comprehensible input, is demonstrated to be problematic. Based…

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.…

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…

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…

This book is based on a series of four lectures, presented at National Taipei University, Taiwan, which reviewed the fundamentals of second language acquisition theory, presented original research supporting the theory, offered counterarguments to criticisms, and explored new areas that appeared to have promise for progress in both theory and…

Studies of the impact of formal instruction consistently show that more instruction results in modest increases in consciously-learned competence, a conclusion that is consistent with the claims of the monitor hypothesis. Reviews research in which the impact of direct instruction in grammar is measured directly, discusses individual studies…

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)

How to acquire a second language is a question of obvious importance to teachers and language learners, and how to teach a second language has also become a matter of concern to the linguists' interest in the nature of primary linguistic data. Starting with the development stages of second language acquisition and Stephen Krashen's theory, this…

Discusses the work of Stephen Krashen, examining his insights and discussing the views of his critics. (Author/VWL)
