The fact that during language acquisition, children are largely only exposed to positive evidence, [8] meaning that the only evidence for what is a correct form is provided, and no evidence for what is not correct, [9] was a limitation for the models at the time because the now available deep learning models were not available in late 1980s. [10]
[5] [6] Other computing technologies applied to ICALL include Knowledge representation (KP), Automatic Speech Recognition (ASR), Neural networks, User modelling, and Expert systems. In relation to language learning, ICALL utilizes linguistic theory and theories of second-language acquisition in its pedagogy. [5] [6]
Complex dynamic systems theory in the field of linguistics is a perspective and approach to the study of second, third and additional language acquisition. The general term complex dynamic systems theory was recommended by Kees de Bot to refer to both complexity theory and dynamic systems theory .
Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. [ 2 ] A common type of systems modeling is function modeling , with specific techniques such as the Functional Flow Block Diagram and IDEF0 .
The Input Processing theory, put forth by Bill VanPatten in 1993, [1] describes the process of strategies and mechanisms that learners use to link linguistic form with its meaning or function. [2] Input Processing is a theory in second language acquisition that focuses on how learners process linguistic data in spoken or written language. [3] [2]
Language acquisition is, therefore, an active process in which the learner focuses on cues and meaning and makes intelligent guesses. Additional demands are placed upon teachers working in a technological environment incorporating constructivist and whole language theories.
IDEF6 model of IDEF4 design activities. IDEF6, or integrated definition for design rationale capture, is a method to facilitate the acquisition, representation, and manipulation of the design rationale used in the development of enterprise systems. Rationale is the reason, justification, underlying motivation, or excuse that moved the designer ...
The Bottleneck Hypothesis [23] suggests that certain linguistic features in second-language acquisition (SLA) act as a bottleneck, limiting the progression of learners in acquiring the full grammatical system of the target language. According to this hypothesis, functional morphology is the most challenging aspect for adult L2 learners to acquire.
