Comparing Syntactic Complexity: Research Papers Written by Undergraduate Researchers and Published Research Papers

Abstract

This study compared syntactic complexity between undergraduate students’ research papers and published research papers. A 2 (Groups: experts, students) × 4 (Sections: introduction, methods, results, discussions) mixed factorial analysis of variance (ANOVA) was conducted on each of the following variables: T-unit length, clause density, the frequencies of adverbial clauses, relative clauses, and nominal clauses. The analyses showed there were longer T-units and fewer adverbial clauses in the published papers than in the student papers. Section effects were robust. Qualitative analyses were further conducted to reveal how the student research paper is different from the published papers syntactically. Implications for education were discussed.
