Stephen D. Krashen (born May 14,1941) is an American linguist,educational researcher and activist,who is Emeritus Professor of Education at the University of Southern California. [1] He moved from the linguistics department to the faculty of the School of Education in 1994.
Stephen Krashen received a Ph.D. in Linguistics from the University of California,Los Angeles in 1972. [2] Krashen has among papers (peer-reviewed and not) and books,more than 486 publications,contributing to the fields of second-language acquisition,bilingual education,and reading. [3] He introduced various hypotheses related to second-language acquisition,including the acquisition-learning hypothesis,the input hypothesis,the monitor hypothesis,the affective filter,and the natural order hypothesis. [4] Most recently,Krashen promotes the use of free voluntary reading during second-language acquisition,which he says "is the most powerful tool we have in language education,first and second." [5]

As education policy in Krashen's home state of California became increasingly hostile to bilingualism, he responded with research critical of the new policies, public speaking engagements, and with letters written to newspaper editors. During the campaign to enact an anti-bilingual education law in California in 1998, known as Proposition 227, Krashen campaigned aggressively in public forums, media talk shows, and conducted numerous interviews with journalists writing on the subject. After other anti-bilingual education campaigns and attempts to enact regressive language education policies surfaced around the country, by 2006 it was estimated that Krashen had submitted well over 1,000 letters to editors.
Krashen has been an advocate for a more activist role by researchers in combating what he considers the public's misconceptions about bilingual education. Addressing the question of how to explain public opposition to bilingual education, Krashen queried, "Is it due to a stubborn disinformation campaign on the part of newspapers and other news media to deliberately destroy bilingual education? Or is it due to the failure of the profession to present its side of the story to reporters? There is a great deal of anecdotal evidence in support of the latter." Continuing, Krashen wrote, "Without a serious, dedicated and organized campaign to explain and defend bilingual education at the national level, in a very short time we will have nothing left to defend." [6]
Tracy Dale Terrell was an American education theorist who, along with Stephen Krashen, wrote The Natural Approach. The natural approach is a comprehension-based language learning methodology which emphasizes the idea of exposure and the lowering of affective or emotional barriers to learning.
A second language (L2) is a language spoken in addition to one's first language (L1). A second language may be a neighbouring language, another language of the speaker's home country, or a foreign language. A speaker's dominant language, which is the language a speaker uses most or is most comfortable with, is not necessarily the speaker's first language. For example, the Canadian census defines first language for its purposes as "the first language learned in childhood and still spoken", recognizing that for some, the earliest language may be lost, a process known as language attrition. This can happen when young children start school or move to a new language environment.
TPR Storytelling is a method of teaching foreign languages. TPRS lessons use a mixture of reading and storytelling to help students learn a foreign language in a classroom setting. The method works in three steps: in step one the new vocabulary structures to be learned are taught using a combination of translation, gestures, and personalized questions; in step two those structures are used in a spoken class story; and finally, in step three, these same structures are used in a class reading. Throughout these three steps, the teacher will use a number of techniques to help make the target language comprehensible to the students, including careful limiting of vocabulary, constant asking of easy comprehension questions, frequent comprehension checks, and very short grammar explanations known as "pop-up grammar". Many teachers also assign additional reading activities such as free voluntary reading, and there have been several easy novels written by TPRS teachers for this purpose.

Second-language acquisition (SLA), sometimes called second-language learning—otherwise referred to as L2acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. This involves learning an additional language after the first language is established, typically through formal instruction or immersion. A central theme in SLA research is that of interlanguage: the idea that the language that learners use is not simply the result of differences between the languages that they already know and the language that they are learning, but a complete language system in its own right, with its own systematic rules. This interlanguage gradually develops as learners are exposed to the targeted language. The order in which learners acquire features of their new language stays remarkably constant, even for learners with different native languages and regardless of whether they have had language instruction. However, languages that learners already know can have a significant influence on the process of learning a new one. This influence is known as language transfer.
Sheltered instruction is an educational approach designed to make academic content more accessible to English language learners (ELLs) while promoting their language development. It involves modifying instruction to accommodate students' language proficiency levels and providing additional support to help comprehend and engage with material effectively.
Sequential bilingualism occurs when a person becomes bilingual by first learning one language and then another. The process is contrasted with simultaneous bilingualism, in which both languages are learned at the same time.
The critical period hypothesis is a theory within the field of linguistics and second language acquisition that claims a person can only achieve native-like fluency in a language before a certain age. It is the subject of a long-standing debate in linguistics and language acquisition over the extent to which the ability to acquire language is biologically linked to developmental stages of the brain. The critical period hypothesis was first proposed by Montreal neurologist Wilder Penfield and co-author Lamar Roberts in their 1959 book Speech and Brain Mechanisms, and was popularized by Eric Lenneberg in 1967 with Biological Foundations of Language.
Language teaching, like other educational activities, may employ specialized vocabulary and word use. This list is a glossary for English language learning and teaching using the communicative approach.
In the field of second language acquisition, there are many theories about the most effective way for language learners to acquire new language forms. One theory of language acquisition is the comprehensible output hypothesis.
The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group. The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis. The input hypothesis was first published in 1977.
Extensive reading (ER) is the process of reading longer, easier texts for an extended period of time without a breakdown of comprehension, feeling overwhelmed, or the need to take breaks. It stands in contrast to intensive or academic reading, which is focused on a close reading of dense, shorter texts, typically not read for pleasure. Though used as a teaching strategy to promote second-language development, ER also applies to free voluntary reading and recreational reading both in and out of the classroom. ER is based on the assumption that we learn to read by reading.
Paul Nation is an internationally recognized scholar in the field of linguistics and teaching methodology. As a professor in the field of applied linguistics with a specialization in pedagogical methodology, he has been able to create a language teaching framework to identify key areas of language teaching focus. Paul Nation is best known for this framework, which has been labelled The Four Strands. He has also made notable contributions through his research in the field of language acquisition that focuses on the benefits of extensive reading and repetition as well as intensive reading. Nation's numerous contributions to the linguistics research community through his published work has allowed him to share his knowledge and experience so that others may adopt and adapt it. He is credited with bringing « legitimization to second language vocabulary researches » in 1990.
The main purpose of theories of second-language acquisition (SLA) is to shed light on how people who already know one language learn a second language. The field of second-language acquisition involves various contributions, such as linguistics, sociolinguistics, psychology, cognitive science, neuroscience, and education. These multiple fields in second-language acquisition can be grouped as four major research strands: (a) linguistic dimensions of SLA, (b) cognitive dimensions of SLA, (c) socio-cultural dimensions of SLA, and (d) instructional dimensions of SLA. While the orientation of each research strand is distinct, they are in common in that they can guide us to find helpful condition to facilitate successful language learning. Acknowledging the contributions of each perspective and the interdisciplinarity between each field, more and more second language researchers are now trying to have a bigger lens on examining the complexities of second language acquisition.
Focus on form (FonF), also called form-focused instruction, is an approach to language education in which learners are made aware of linguistic forms – such as individual words and conjugations – in the context of a communicative activity. It is contrasted with focus on forms, in which forms are studied in isolation, and focus on meaning, in which no attention is paid to forms at all. For instruction to qualify as focus on form and not as focus on forms, the learner must be aware of the meaning and use of the language features before the form is brought to their attention. Focus on form was proposed by Michael Long in 1988.
The interaction hypothesis is a theory of second-language acquisition which states that the development of language proficiency is promoted by face-to-face interaction and communication. Its main focus is on the role of input, interaction, and output in second language acquisition. It posits that the level of language that a learner is exposed to must be such that the learner is able to comprehend it, and that a learner modifying their speech so as to make it comprehensible facilitates their ability to acquire the language in question. The idea existed in the 1980s, and has been reviewed and expanded upon by a number of other scholars but is usually credited to Michael Long.
The natural approach is a method of language teaching developed by Stephen Krashen and Tracy Terrell in the late 1970s and early 1980s. The Natural Approach has been used in ESL classes as well as foreign language classes for people of all ages and in various educational settings, from primary schools to universities. It aims to foster naturalistic language acquisition in the classroom setting by emphasizing communication and limiting conscious grammar study and explicit correction of student errors. Efforts are also made to make the learning environment as stress-free as possible, by lowering the affective filter. In the natural approach, language output is not forced, but allowed to emerge spontaneously after students have attended to large amounts of comprehensible language input. Comprehensible input is the content that language learners are exposed to in the target language. Krashen suggests that language learners should be able to understand the comprehensible input provided at their current levels of language acquisition, while also making it as interesting and engaging as possible.

GrapeSEED is a research-based oral language acquisition and critical listening program for teachers that allows students to obtain the English language naturally. This natural approach, developed by Stephen Krashen, a linguist and researcher in the fields of second-language acquisition and bilingual education, and Tracy D. Terrell, an education theorist, is intended to give language learners the ability to "communicate with native speakers of the target language" by having students, who are taught in a classroom setting, first comprehend the language, and then "Speech production emerges as the acquisition process progresses."
