L1 and L2 acquisition

  1. 1. Fla<br /> & <br />sla<br />
  2. 2. HAVE YOU EVER THOUGHT ABOUT THIS???<br /><ul><li>Whyevery single person can acquirethefirstlanguage (L1) easily?
  3. 3. Whyveryfewpeoplemanagetoacquire a secondlanguage (L2) succesfully?
  4. 4. Why, eventhoughyou try yourbest as a teacher, somelearnershave a hard time acquiring L2.</li></li></ul><li>Do you, as a teacher, feellikethisfrom time to time?<br />EVERYBODY ELSE UNDERSTOOD<br />I DON’T UNDERSTAND<br />WHY “FULANITO” DOESN’T GET ANYTHING?<br />
  5. 5. FIRST LANGUAGE ACQUISITION.<br />Noam Chomsky: <br /> “Languageisinnate.” We are bornwith rules of language in ourheads= Universal grammar<br />JeremyHarmer:<br />“Unlessthereissomethingwrongwiththemmentallyorphysically, allchildrenacquire a language as theydevelop” (Harmer,1988). <br />

  7. 7. FLA stages (l1)<br />TWO-WORD STAGE <br />18-24 months<br />Mini-sentenceswith simple semanticrelations.<br />Examples: More cereal, papa away, no bed, byebye car, dry pants.<br />HOLOPHRASTIC STAGE<br />9-18 months<br />Childrencommunicatewith 1 word, relatingittomany similar things.<br />Theyunderstand more thanthey can produce.<br />
  8. 8. FLA stages (l1)<br />TELEGRAPHIC STAGE <br />24-30 months<br />Word combinations:<br /> Me wantthat<br />Whathername?<br />Chairfalldown!<br />Thesesentences resemble to short messages in a telegram.<br />There are a lot of syntaxerrors.<br />MULTIWORD STAGE<br />30 + months<br />Grammaticalorfunctionalstructures emerge (thesintaxstage).<br />Childrenlanguagebloomsintofluentgrammaticalconversation.<br />
  9. 9. SECOND LANGUAGE ACQUISITION<br />Students learning a second language go through five stages: Preproduction, Early Production, Speech Emergence, Intermediate Fluency, and Advanced Fluency (Krashen & Terrell, 1983). <br />Students already have previous knowledge of language (L1).<br />Speed of progress through the stages depends on level of education, family background, amount of exposure to the target language, among others.<br />
  10. 10. Krashen’s theory of Language acquisition VS. Language learning <br />ACQUISITION<br />Itis natural.<br />Itis informal.<br />Itissubconscious.<br />Notaware of grammar.<br />Itiscommunicative.<br />LEARNING<br />Ithappens in an artificial setting.<br />Itis formal.<br />Itis rule conscious.<br />Thereisawareness of grammar and vocabulary.<br />
  11. 11. Activitiesassociatedwithlearninghavetraditionallybeenused in languageschools and havegoodresults in knowledge “about” language, butnot in fluency. ( Yule, 1955 ). <br />"Acquisition requires meaningful interaction in the target language - natural communication - in which speakers are concerned not with the form of their utterances but with the messages they are conveying and understanding." <br />Stephen Krashen<br />
  12. 12. SLA STAGES (L2)<br />Pre-production (silent period)<br />The learner:<br /> Has minimal comprehension. <br /> Does not speak at all. <br /> Nods "Yes" and "No." <br /> Draws and points. <br /> Uses gesturing.<br />Repeatslike a “parrot” everything<br />Thisstagemaylast up to 6 months. <br />Early production<br />The learner:<br />Has limited comprehension <br />Produces one or two-word responses. <br />Uses present-tense verbs. <br /> Answers yes / no questions.<br /> Benefits from: realia, vocabulary with pictures, listening activities.<br />From 6 monthsto 1 year.<br />
  13. 13. SLA STAGES (L2)<br />Intermediatefluency<br />The learner:<br />Has excellent comprehension. <br />Makes few grammatical errors. <br /> Willing to express opinions and share thoughts.<br />Writing will have errors.<br />From 3 to 5 years<br />Speechemergence<br />The learner:<br />Has good comprehension. <br />Can produce simple sentences. <br />Makes grammar and pronunciation errors. <br />Asks simple questions, that may or may not be grammatically correct, such as: May I go to bathroom?<br />From 1 to 3 years.<br />
  14. 14. Whyveryfewpeoplemanagetoacquire a secondlanguagefluently?<br />Learners are notallowedtohave a silentperiod, they are askedto produce whenthey are notready = Interlanguage<br />Interlanguageisthe mixture of L1 and L2 tobeabletocommunicate =interference.<br />Interference = errors.<br />Fossilization: no furtherlearningappearspossible. Learnerswillhavethesame error despite of anycorrectionorgrammaticalexplanation. <br />CriticalPeriod: Beforetheage of 12, fluencymaybereached. After, thisis no longerpossibleduetothechanges in thebrain.<br />Affectivefilter: Motivation, self-confidence, and anxiety all affect language acquisition.<br />
  15. 15. SLA STAGES (L2)<br />AdvancedFluency<br />The student has a near-native level of speech<br />It takes learners from 5 to 10 years to become fluent.<br />
  16. 16. Whychildrenseemtoacquire l2 betterthanadults?<br />Childrenhaveaccessto Universal Grammar.<br />Adults are more influencedby L1.<br />Children are more motivatedthanadults.<br />Childrenrecieve more imput in thesecondlanguagethanadults do.<br />
  17. 17. The use l1 in the l2 classroom<br />ADVANTAGES<br />Accordingto Paul Seligson:<br />Unavoidableanyway.<br />Reduces affectivefilters.<br />Practicetranslation.<br />Providesfeedback.<br />Discussidioms.<br />
