Language Knowledge Emerges from Language Use: Usage-Based Approaches to SLA

In the field of second language acquisition (SLA), a fundamental debate has long persisted: Is language ability innate or acquired? The "nativist" perspective, championed by Chomsky, once dominated, positing the existence of an inborn "Universal Grammar" in the human brain. However, since the late 20th century,

The Essence of Second Language Fluency Is the Automation of Language Processing

The essence of second language fluency lies in transforming the language processing from a conscious, effortful controlled operation into an unconscious, efficient automated one. This core idea has been extensively explored in the field of Second Language Acquisition. The Input Processing Model proposed by Bill VanPatten and the Skill Acquisition

The Limited Input, The Infinite Output

In the 1950s and 1960s, Noam Chomsky published three seminal works that progressively established and deepened his theory of Generative Grammar, fundamentally redirecting the course of modern linguistics. These three books form a complete intellectual system, moving from theoretical construction, through model refinement, to philosophical elevation. 在20世纪50年代至60年代，诺姆·乔姆斯基发表了三部开创性著作，逐步确立并深化了其生成语法理论，

The Beginning of Programmed Instruction: "The Science of Learning and the Art of Teaching"

In 1954, B.F. Skinner published his seminal article, "The Science of Learning and the Art of Teaching," which presented a core argument: since we now possess a science of learning—behavioral psychology—we should use this science to fundamentally reform the art of teaching. From a scientist&

Interlanguage: The Inevitable Path for Every Second Language Learner

In 1972, linguist Larry Selinker, in his seminal paper "Interlanguage", proposed the groundbreaking Interlanguage Theory. This theory revolutionized our understanding by positing that the linguistic system constructed by second language learners is not a flawed imitation of the target language waiting to be corrected, but an independent, systematic,

It's okay to make mistakes: "The Significance of Learners' Mistakes"

In 1967, S. P. Corder published the article "The Significance of Learners' Mistakes," which can be regarded as the beginning of Second Language Acquisition research. Before SLA became an independent discipline, errors in language learning were often seen as signs of learning failure, primarily attributed to interference

Krashen's Input Hypothesis: "There is Only One Way to Acquire a Second Language"

Stephen Krashen, in the late 1970s and early 1980s, proposed a series of hypotheses that formed a highly influential theory of second language acquisition. Among them, the "Input Hypothesis" serves as the cornerstone of this framework. Its highly generalized and exclusive assertion—that comprehensible input is the only
