An Empirical Study on Syntactic Complexity of Second Language Writing in China Based on Dynamic System Theory
Download as PDF
Dynamic System Theory is the Latest Development in Applied Linguistics. It Focuses on the Interaction of Various Internal Systems in the Process of Language Acquisition and the Interconnection of Various Factors within the System. Second Language Writing is Not Only a Major Difficulty in Second Language Learning, But Also a Hot Topic in the Field of Second Language Acquisition. This Paper Studies the Syntactic Complexity of Second Language Writing in China by Using Dynamic System Theory. Research Shows That There is a Significant Positive Correlation between Complexity Measurement Factors and Composition Scores, and the Factors Composed of Measurement Variables Such as the Average Number of Clauses Per Sentence, the Average Number of Verb Phrases Per Unit, and the Average Number of Clauses Per Unit Have Higher Prediction Accuracy on Composition Scores. Meanwhile, Lexical Chunks Have Positive Effects on Improving Students' Second Language Writing Ability.
