Integrated writing tasks that combine reading, listening, and writing have become increasingly popular in assessing academic writing. These tasks are seen to offer more authenticity, improve fairness, and provide positive washback effects of the test on learning and teaching of English around the globe. However, the integrated nature of these tasks can pose some issues, such as construct-related validity and verbatim source use. Given that the inferences made from test scores depend upon the construct of the measure, it is important to have a working knowledge of how strategies are used on integrated writing tests as part of the process of construct validation. This study investigates the relationship between second language writers’ strategy use and performance on an integrated reading-listening-writing test using structural equation modeling and qualitative approaches. Data were collected from 161 non-native English-speaking students. The students first took an integrated reading-listening-writing test and followed by a strategy inventory on how they thought while completing the test. Twenty students, ten in the high-performance group and ten in the low-performance group, participated in a retrospective interview. Exploratory factor analysis (EFA) was used to identify the clusters of items based on three hypothetical factors: Rhetorical, Self-Regulatory, and Test-Wiseness Strategy Use. Confirmatory factor analysis (CFA) was then utilized to test the hypothetical relations between observed and latent variables. Subsequently, structural equation modeling (SEM) was used to model the relationship between students’ self-reported strategy use and their test performance. The data collected from retrospective interviews, an open-ended questionnaire, and planning sheets were analyzed to triangulate quantitative results and provide supplementary information in interpreting the quantitative data. The study illuminates the nature of integrated writing strategy use, the nature of integrated writing performance, and the relationship between strategy use and performance on an integrated reading-listening-writing test. The results of the study have implications for second language writing assessment and instruction as well as theory in second language academic writing. / text

abstract: The Stretch Model is a model of first year composition (FYC) that “stretches” the first semester's class over two semesters in order to help writing students who arrive at university with low test scores to succeed in their composition courses. Originally piloted in 1994 at Arizona State University (ASU), the Stretch Model of composition has been found to be effective in terms of retention and persistence of first language (L1) writers (e.g., Glau, 1996; 2007). It has become known at ASU and abroad as the Stretch Program. Since 1997, a separate track of the Stretch Program has been solely for second language (L2) writers, and L2 writing students are now roughly 17% of the program's population. Until fairly recently, there was no attempt to collect L2 data to support the Stretch Program's claims for effectiveness for the L2 population. As many universities across the nation have garnered inspiration for their own programs ("Stretch Award" 2016), and L2 writers have the potential to be in any composition class (Matsuda, Saenkhum, & Accardi, 2013), it is imperative to include the voices of L2 writers in the analysis of the Stretch Program. This study addresses the need for L2 writers' voices to be included in the analysis of the Stretch Program at Arizona State University. From the quantitative analysis of 64,085 students’ institutional data records, and qualitative analysis of 210 student surveys, findings include L2 writers have the highest rates of passing, but the lowest rates of persistence in the three-semester first year composition requirement when compared to Stretch L1 students and the traditional FYC population. Survey data also lends L2 student perceptions to complicate the main features of the Stretch Program including perceived writing improvement, having the same teacher and classmates for two semesters, and having more time to work on their writing. The quantitative findings are consistent with Snyder’s (2017a) analysis of the 2012 fall Stretch Program L1 and L2 cohorts. / Dissertation/Thesis / Doctoral Dissertation English 2018
