Research has shown that collaboratively produced texts are better in quality compared with individually written texts. However, no study has considered the role of collaboration in authorial voice, which is an essential element in current writing curricula. This study analyzes the effects of collaborative task performance in the quality of L2 learners’ argumentative texts and in their authorial voice strength. A total of 306 upper-intermediate L2 learners were selected and divided into independent ( N = 130) and paired ( N = 176) groups. Each learner/pair was asked to write one argumentative text. The quality of writings was determined by a quantitative analysis that included three measures of complexity, accuracy, and fluency (CAF). Participants’ authorial voice strength was assessed by two raters using an analytic voice rubric. Comparison of means revealed that pairs outperformed independent writers in all CAF measures. However, the results for the role of collaboration in authorial voice were mixed: While pairs were more successful than independent writers in manifesting their ideational voice, independent writers outperformed pairs with regard to affective and presence voice dimensions and holistic voice scores. The article concludes that, despite its positive implications for L2 writing, collaborative writing may pose challenges for learners’ authorial stance taking.

The purpose of this study was twofold: (a) to examine the level of authorial voice strength among Iranian second language (L2) writers; and (b) to investigate the relationship between L2 learners’ authorial voice strength and the quality of their argumentative written task performances. Argumentative writing samples were elicited from 129 upper-intermediate L2 learners in writing courses. To quantify learners’ voice strength, these samples were scored by two raters using an analytic voice rubric. Raters also provided a holistic rating of the overall authorial voice strength in written argumentations. The quality of argumentations was measured using the TOEFL scoring rubric. While descriptive results indicated that learners demonstrated a low level of voice strength in their argumentations, results from Multiple Regression Analysis (MRA) suggested positive associations between voice strength along with two of its dimensions and the quality of writings. Moreover, results from Multiple Correspondence Analysis (MCA) pointed to the association of low and mid-level of writing quality and low voice strength, and the prevalence of high and mid voice strength in learners with high proficiency in writing. Finally, while an Item Response Theory (IRT) analysis revealed that the ‘presence’ dimension of authorial voice was the most difficult one for L2 learners, a Differential Item Functioning (DIF) analysis showed that the difficulty of the three voice dimensions did not differ significantly across genders. The findings were discussed regarding English L2 writing within the Iranian context.

This study investigates the direct and/or indirect effects of some cognitive (working memory capacity) and affective (writing anxiety and writing self-efficacy) variables on the complexity, accuracy, and fluency (CAF) of second language (L2) learners’ writings. To achieve this goal, 232 upper-intermediate English learners performed an automated version of a working memory capacity task (A-OSPAN) and a timed narrative writing task in L2. Furthermore, participants were asked to complete two self-report questionnaires. The proposed path model adequately fitted the data, and results of path analyses indicated the following: All three measures of L2 writing were directly predicted by learners’ writing self-efficacy; writing self-efficacy affected CAF indirectly through writing anxiety; the direct paths from writing anxiety to all measures of L2 writing were negatively significant; higher working memory spans directly predicted higher L2 writing scores regarding complexity and fluency, but negatively affected learners’ accuracy scores. Based on these findings, the author discusses techniques for enhancing learners’ writing self-efficacy, reducing their anxiety, and helping them make efficient use of working memory resources.
