A key writing skill is the capability to clearly convey desired meaning using available linguistic knowledge. Consequently, writers must select from a large array of idioms, vocabulary terms that are semantically equivalent, and discourse features that simultaneously reflect content and allow readers to grasp meaning. In many cases, a simplified…

Which theoretical and empirical insights can inform language-in-education research that advances equitable and high-quality learning at school? In this three-part article, I first draw from various sources to foreground the urgent need to counteract linguicism and epistemic injustices and to commit to more just and rigorous scientific practices in…

This study investigated the impact of conversational agent formality on the quality of summaries and formality of written summaries during the training session and on posttest in a trialog-based intelligent tutoring system (ITS). During training, participants learned summarization strategies with the guidance of conversational agents who spoke one…

We investigated the dimensionality and relations between L1 (a speaker's first language) and L2 (a speaker's second language) writing skills in narrative and informational genres and higher order cognitive skills--inference, perspective taking, and comprehension monitoring--for Spanish-English dual language learners in primary grades. Dimensions…

An important topic in writing research has been the use of cohesive features. Much of this research has focused on local and text cohesion. The few studies that have studied global cohesion have been restricted to first language writing. This study investigates the development of local, global, and text cohesion in the writing of 57 language (L2)…

This study explores whether linguistic features can predict second language writing proficiency in the Test of English as a Foreign Language (TOEFL iBT) integrated and independent writing tasks and, if so, whether there are differences and similarities in the two sets of predictive linguistic features. Linguistic features related to lexical…

This study investigates the potential for linguistic microfeatures related to length, complexity, cohesion, relevance, topic, and rhetorical style to predict L2 writing proficiency. Computational indices were calculated by two automated text analysis tools (Coh- Metrix and the Writing Assessment Tool) and used to predict human essay ratings in a…

Research has demonstrated that students in dual-language immersion programs perform as well as, or better than, their peers in core academic content areas by late elementary school. The extent to which immersion education fosters bilingualism, however, has received less attention in the literature. Using data from a four-year efficacy study of…

This report contributes to understanding of the academic trajectories of ELL [English language learner] students within the FWISD [Fort Worth Independent School District]. The focus is on all students who enrolled as first-time sixth graders at the International Newcomer Academy (INA) in the 2006-2007 school year, a cohort of 48 students. These…

This report is part of a long-term collaboration of the Quality Teaching for English Learners initiative at WestEd with the Fort Worth Independent School District. The focus of this report is on a historical cohort of ninth graders who were enrolled at the International Newcomer Academy in the 2009-2010 school year. This report follows this cohort…

We conducted a randomized field trial to test an academic vocabulary intervention designed to bolster the language and literacy skills of linguistically diverse sixth-grade students (N = 2082; n = 1469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…
