Key Concepts

Definition

  • Learning any language after age of 4
  • Focus: second, third language (Ln)
    1. Includes both widely spoken and foreign languages
  • Types of learning:
    1. Formal (in classroom, planned, systematic)
    2. Informal (incidental, thru interaction)

Krashen's (un)Conscious Learning

  • Distinction between conscious learning and unconscious acquisition
  • Acquisition: unconscious, informal
  • Learning: conscious, formal instruction
  • Or rather, explicit and implicit learning

Other Theories

  • Cognitive focus: historically dominant, individual learner based
  • Sociocultural focus: language as a social phenomenon

Levels of Language

  • Phonology: Sounds
  • Morphology: Words
  • Lexis: Vocabulary
  • Syntax: Sentences
  • Semantics: Meaning
  • Pragmatics: Context
  • Discourse: Communication

Well Known Linguist's Competence & Performance

  • Competence: underlying knowledge of language
  • Performance: actual use of language in context
  • Well known linguist also sez:
    1. Linguists to focus on competence
    2. It reflects internalized rules of language
    3. Performance less reliable
    4. Because does not reflect true competence (errors)

Other Language Target Theories

  • Traditional view: goal of language learning approximate native speaker competence
  • Challenges:
    1. Selinker: Learners develop own inter-language, not a copy of target language
    2. Multi-competence: multilingual speakers develop merged language system with languages influencing each other
  • Lingua franca is dead
    1. L2 learning to focus on capacity in diverse contexts (World Englishes)

New classes

  • Advanced L2 users?
  • Lingua franca speakers?
  • Mutlicompetent speakers?

Nature and Nurture in SLL

  • Innate (generic predispositions) vs environmental influences
    1. Understanding L1/L2 learning

Skinner vs Well Known Linguist

  • Skinner sez: language learned through behaviorist mechanisms (trial error, reward)
    1. Learning shaped by environment
  • Well known linguist sez: language too complex to be learned from environmental input, use innate predisposition (universal grammar)
    1. Learning influenced by innate cognitive structures

Other Terms

  • Innate predispositions
    1. Humans capable of learning multiple languages with time, motivation, exposure
  • Environmental conditions for L2
    1. Circumstances differ from L1, especially adults

Adults and SLL

  • Fossilization
    1. Learners fail to achieve native like proficiency, fluency despite effort
    2. May happen even with active engagement and tons of classes
  • Psycholinguistic explanations
    1. Cognitive mechanisms for language learning diminish with age (due to L1)
  • Sociolinguistic explanations
    1. Lack of full integration into L1 communities and desire for distinct multilingual identity

Cross-Linguistic Influences

  • Language transfer
    1. Influence of L1 on L2
  • Positive transfer
    1. Correct usage of similarities between L1 and L2
    2. French word order
  • Negative transfer
    1. Language errors caused by similarities between both
    2. "I have 30 year age" vs "I am 30 years old"

Typo-logical Distances

  • Degree of similarity between linguistic systems of L1 and L2
  • Close distance:
    1. Germanic languages share similar word order, vocabulary
  • Distant distance
    1. Japanese and other logo-graphic languages

Relationship Between L2 Use and Learning

  • Input: exposure to language is essential (listening, reading)
    1. Krashen: comprehensible input alone is enough
  • Output: Forces learners to practice and refine (speaking, writing)
    1. Swain: Speaking and writing necessary to refine knowledge

Interaction

  • Psycholinguistic view: Fine tune input based on learners level
  • Sociolinguistic view: Social process with identities and interactions
  • Negative evidence: Feedback on errors can help/hinder learning per context

Perspectives

Learner as Language Processor

  • Processing and

Individual Differences

  • Language aptitude: talent
  • Memory systems: working memory
  • Learning strategies
  • Motivate
  • Language attitudes
  • Willingness to communicate

Learner as Social Being

  • Identity: dynamic and shaped by experiences
  • Learner agency: shapes goals and enviornment
  • Social context: Social properties
