voice in short argumentative texts written by undergraduate learners of english

the present study explored the intensity level of authorial voice in relation to the quality of argumentative writing. 42 undergraduate learners of english as a foreign language (36 girls and 6 boys) spent 45 minutes to individually complete in-class position-taking writing tasks for three weeks. their overall academic writing quality scores assigned based on portfolio assessment were studied in relation to their voice expression quantified using a voice intensity rating scale (virs). findings indicated that, among the components of authorial voice, only “assertiveness” showed a positive moderate relationship with academic writing quality (r=0.45, p≤ 0.05). in the follow-up qualitative analyses of voice-expression strategies, interviews with participants whose voice intensity had been rated either as the strongest or as the weakest showed nine strategies for voice expression. at the sentence-level, high-voice participants most frequently used intensifiers to express assertiveness, while low-voice writers tried to use other lexico-grammatical tools. at the text-level, both high-voice and low-voice participants were concerned about the effect of the topic on their voice expression. the findings imply that undergraduate english as a foreign language writers do try to express voice and that the required strategies can be one of the targets of efl writing research and instruction.
