Vygotsky came up with the Zone of Proximal Development. It is the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult guidance or in collaboration with other learners. -
-
Assumed that language was primarily an oral phenomenon. Stems from the research conduct of Indian languages, which had no written system. Written language was seen as a secondary system to speech. Was influenced by behaviorism. -
Viewed language learning as a process of conditioning, as a result of a stimulus-response-reinforcement chain. According to influence of behaviorism Imitation, practice and positive reinforcement lead to habits and the acquisition of language. -
Chomsky claimed that children are innately predisposed to acquire language. ideas that he introduced include: universal grammar, deep structure vs. surface structure, competence vs. performance -
-
Several studies showed that learners are active participants in using language. They can use their own skills and follow rules. -
-
Selinker coined the term "interlanguage," which is the language of the learner at any given point in time. Provides a foundation for the idea of the evolving nature of language acquisition. -

Krashen built on innatist views and proposed explanations he named the Monitor Model. It consisted of: the acquisition-learning hypothesis, the monitor hypothesis, the natural order hypothesis, the input hypothesis and the affective filter hypothesis. Comprehensible input consists the the i+1 level -
Long's interaction hypothesis claims that input comes in various ways including from others. The ways are targeted: simplification on input, using linguistic features that are familiar and modifying the interactional structure of the conversation. -
Input is insufficient conditton for language development. Learners also need opportunities to produce output. She claims that learners discover the gap between what they want to say and what they are able to say. Speaking also provides a way for learners to try out new rules and modify them. Lastly, learners activity reflect on what they know about the target language. -
Refined the model of communicative competence as originally proposed by Canale & Swain. This most current model of communicative competence consists of: social cultural competence, discourse competence, linguistic competence, formulaic competence, interactional competence, strategic competence -
Learners restructure their language when they integrate into their memories the input that they hear or read. They create a hypothesis and test it. Errors are a natural part of the process.
