This study investigates coherence issues in Chinese paragraph writing among learners of Chinese as a second language, highlighting challenges not only in surface cohesion but also in discourse-level organization. Adopting Rhetorical Structure Theory (RST) as an analytical framework, the study conducts discourse analysis of learner compositions and reveals that the rhetorical structures generated through RST closely correspond with learners’mind maps produced during the writing planning stage. The analysis identifies three major sources of incoherence: inappropriate lexical choices, misuse of cohesive devices, and isolated clauses that fail to integrate into the overall discourse structure. In response, the study proposes a pedagogical framework for Chinese writing instruction that integrates RST with mind mapping as an instructional scaffolding. This framework supports learners throughout the writing process—from planning, translating to reviewing. During the revision phase, learners are guided to compare their compositions with their mind maps and examine RST relations between clauses, allowing them to refine word choice and cohesion strategies. This integrated approach enhances textual coherence and helps learners avoid fragmented writing, ultimately leading to more effective and structured compositions. |
