Syntactic complexity in second language (L2) writing: Comparing students’ narrative and argumentative essays

This study investigated the distinctive structural characteristics between narrative and argumentative texts and examined the relationships among syntactic measures within each genre. Conducted with 161 Chinese college freshmen, the study employed 14 syntactic complexity measures to analyze 322 essays comprising both narrative and argumentative types. The research questions focused on identifying syntactic measures that differentiate between the two genres and the correlational strength among these measures. Results indicated nuanced differences in syntactic complexity, with argumentative essays demonstrating slightly higher complexity in most measures, particularly in the length of production unit, amount of coordination, and degree of phrasal sophistication. Notably, no significant differences were found in overall sentence complexity or measures of subordination. These findings suggested that these aspects do not distinguish between genres for these second language (L2) writers. Correlations within syntactic measures were also analyzed and revealed strong relationships between certain measures within the same category for both essay types. However, there were some distinct patterns of correlation between the two genres. Implications for L2 writing assessment and future studies were discussed.
