Natural or Artificial: Is the Route of L2 Development Teachable James. P. Lantolf, Penn State University Zhang Xian, Rice University Outline of Presentation Background Statement of Problem Theoretical Framework Design Results Discussion Second Language Acquisition Cognitive SLA Cognitive-interactionist: understand the interaction of learner-internal and leaner-external variables Purpose: find universal patterns of L2 learning so that L2 can be explained as a general phenomenon (Ortega, 2009) Piagetian developmental psychology Roots of Cognitive SLA: Progressivism I Progressivism a consequence of solution to Cartesian Dualism (mind & world are different substance and world is subordinate to mind) Basic Tenet: to educate children effectively it is vital to attend to children’s nature, and particularly to their modes of learning and stages of development, and to accommodate educational practice to what we can discover about these. Herbert Spencer--The daily activities of the classroom are subject to the same laws that shaped the stars above and the earth below Change is from simple to complex Roots of Cognitive SLA: Progressivism II Spencer’s Argument In everyday life children learn effortlessly: educators should observe this process and find ways to replicate it in “sensible teaching” Education must conform to natural process of mental evolution Learning was a property of the mind, and the mind is a biological organ on the model of the body: “the mind like the body has a predetermined course of evolution” and as it grows it needs food – aliment of the mind is knowledge John Dewey Proponent of Progressivism Dewey: replicate in school natural learning observed in children’s play in households, streets, and fields. Paradigm form of human learning evident in the way children effortlessly learn language and other knowledge of the world in informal settings Therefore—assume that learning in school must conform to this early effortless learning. Jean Piaget: Proponent of Progressivism Piaget Basic learning comprised of “what the child learns by himself, what no one can teach him and what he must discover alone” Researchers: Describe underlying psychological process of cognitive development Stages determine what knowledge the developing individual can understand Educational prescriptions and programs that cohere with such theories are called “developmentally appropriate” Teachers: effective only if they understand the nature of developmental processes and recognize that teaching must be “subordinate to spontaneous psychological development” Model of Brain/Culture Relationship in General Psychology and SLA Nature (Brain/Mind) Culture Thought Ratner (2012). Macro-Cultural Psychology: A Political Philosophy of Mind. Oxford University Press Culture Not new factor/variable to be correlated with psychology Not psychology as conventionally construed and then add culture as conventionally construed Reconceptualize psychology as a cultural phenomenon, a cultural specimen, a part of human civilization. Vygotsky’s Cultural Psychology Culture creates special forms of behavior It modifies the activity of mental functions It constructs new superstructures in the developing system of human behavior Social Origin of Cognition Every higher mental function was external because it was social before it became an internal, strictly mental function, it was formerly a social relation of two people. The means of acting on oneself is initially a means of acting on others or a means of action of others on the individual. Vygotsky Vygotsky: natural and cultural component to psychological development Separate natural and cultural was a mistake Fundamental nature of human development shaped by culture in conjunction with biological endowment. Modeling Vygotsky’s Theory of Cultural Development Nature Body-Brain Transforming Force (signification) Thinking-Acting Human Psyche (higher functions) Society (Culture) Developmental Education Education: grounded in explicit mediation is ‘artificial development’ of the individual Influences processes of development restructures all functions of behavior in a most essential manner (Vygotsky 1997) Obuchenie (teaching-learning) leads [not follows] development Key: Scientific (systematically organized) concepts Gal’perin’s STI Systemic Theoretical Instruction (STI) Concept-based Instruction (CBI) systematically explaining the concept materializing the concept verbalizing the concept communicative activities internalization Instruction: Gal’perin’s STI Systemic Theoretical Instruction (STI) materialize the concept Schema for Complete Orienting Basis of Action (SCOBA ) Material Activity verbalizing the concept Communicative Thinking I-You Communicative Activities Dialogic Thinking I-Me Internalization Processability Theory Processability Theory (PT, Pienemann, 1998) is a theory of second language development. At any stage of development, L2 learners can produce and comprehend only those second language linguistic forms that the current state of the language processor can handle (Pienemann, 2007, p.137). PT: Universal Sequencing L2 learners follow a relatively rigid path when acquiring certain grammatical structures: some grammatical structures are not “learnable” or “processable” until the previous steps along the learning path have been acquired. (Pienemann, 1998) Pienemann’s (1987) Avowel of Piaget The approach we have taken in the Predictive Framework of SLA and in the Teachability Hypothesis was inspired by our admiration for Jean Piaget’s work on cognitive development. We adopted one concept in particular form Piaget’s word, namely the implicational nature of processing prerequisites for the operations possible at the different stages of acquisition (Piaget, 1950). The testing ground Piaget Vygotsky Describe psychological process Create psychological process Development Predetermined Sequential Progressive Development Not predetermined Complex Non-linear Teaching is subordinate to development Teaching promotes [artificial] development Overview of Processability Theory Learners follow internal processing procedure Governed by processing constraints from Simple to Complex E x a m p l e : M o v e c o n s t i t u e n t s f r o m e n d t o b e g i n n i n g o f utterance simpler than moving constituents from internal to external position or from external to internal position A d v e r b s i n E n g l i s h : I b o u g h t a b o o k y e s t e r d a y > Y e s t e r d a y a b o u g h t a b o o k H e l e f t t h e r o o m q u i e t l y > H e q u i e t l y l e f t t h e r o o m L a n g u a g e F e a t u r e s S u b j e c t t o P r o c e s s i n g C o n s t r a i n t s Q u e s t i o n s i n E n g l i s h N e g a t i o n i n G e r m a n T o p i c a l i z a t i o n Wo r d O r d e r i n C h i n e s e L a n g u a g e F e a t u r e s N O T S u b j e c t t o P r o c e s s i n g C o n s t r a i n t s P l u r a l M a r k i n g i n E n g l i s h C a s e M a r k i n g i n G e r m a n Processable Criterion Three to five sentences with the target structure produced in spontaneous speech production task (Pienemann, 1998) Teachability Hypothesis: Corollary to PT 1.

No. What is the role of teaching? Properly organized Instruction shapes L2 development in a fundamental way. While many studies support the prediction of PT/TH, why does this study challenge the prediction of TH ? Mediation The appropriate type of mediation that satisfies learners’ need (WM, cognitive control). High quality instruction can provide appropriate mediational tools Practice Declarative/Procedural Memory Paradis (2009) Procedural Memory begins to decline at approximately age 7 Declarative Memory strengthens as we age (up to about middle age) PM is responsible for L1 grammar acquisition DM is responsible for L1 lexical acquisition Disagreement between Paradis and Ullman Collocational Knowledge of Lexis No neural connection between PM and DM L2 classroom learning governed by DM Accelerated Access More research needed on this hypothesis References Lantolf, J.
