Stance-taking through APPRAISAL in L1 and L2 English argumentative essays: insights from Vietnamese L2 English.

Stance-taking in academic writing is now a well-established topic of interest in English language research, with explorations across a range of theoretical frameworks including metadiscourse and systemic functional linguistics (SFL). This includes studies investigating second language (L2) stance-taking, particularly those comparing stance features deployed by L1 and L2 English writers. However, studies investigating stance-taking using the APPRAISAL framework for evaluative discursive language across L1 and L2 production are relatively rare. Incorporating the APPRAISAL framework into research on stance-taking enhances our comprehension of evaluative language in academic writing, especially when it comes to cross-linguistic contexts. It also provides useful advantages for language assessment and instruction. In this learner corpus-assisted discourse study, APPRAISAL was used to determine how L1 English speakers and L2 English learners from L1 Vietnamese backgrounds expressed attitudes through their written texts. We also investigate the relationship between use of APPRAISAL resources and expert raters’ perceptions of written stance via a stance rubric. Findings show L2 English students are more explicit in argumentative writing than L1 English writers, despite fewer APPRAISAL choices in L2 texts. Besides, while high-rated texts were associated with more judgemental evaluation and invocation, more personal feelings were expressed in low-rated texts. These findings have implications for the instruction of L2 writers in conveying attitudinal meanings in text, as well as for raters tasked with assessing L2 academic essays for stance.
