Order in Chaos: An Analysis of Senior Three Students’ English Continuation Writing Texts Based on Complex Dynamic Systems Theory

Abstract

This study investigates the dynamic features of language production in senior three students’ English continuation writing. Traditional writing instruction and assessment, which rely on static and linear models, fail to explain the complex fluctuations students exhibit in lexicon, syntax, and discourse construction. To address this issue, the study adopts Complex Dynamic Systems Theory (CDST) as a new analytical framework. Using textual analysis combined with case analysis, the study examines 14 continuation writing texts completed by senior three students from a natural class in a key high school in Taiyuan during a mock exam in the first semester of the 2025 academic year. The analysis focuses on three dimensions: lexicon, syntax, and discourse cohesion. The results show that students’ continuation texts are not simple accumulations of linguistic elements but complex systems characterized by fluctuation and self-organization. Specifically, vocabulary use exhibits obvious nonlinear waxing and waning; syntactic structures show dynamic competition between complex and simple forms; and discourse cohesion emerges as overall coherence from the interaction of micro-level elements. The findings indicate that CDST offers an ecological perspective for understanding students’ writing production. Students should rationally view the nonlinear fluctuations in their writing process, adjust their task-response strategies appropriately, and actively identify and utilize their own linguistic resources, thereby enhancing their English writing competence more effectively.
