Naturalistic language learning is contextually grounded. When people learn their first (L1) and often their second (L2) language, they do so in various contexts. In this dissertation I examine the effect of various contexts on language development. Part 1 describes the effects of textual, linguistic context in reading. I employed an eye-tracking…

Given the multilingual population of the United States, dual-language books (DLBs), or books with the complete text written in two languages, are often recommended for teachers to use in their classrooms to validate students' language and culture, facilitate language learning, and support (bi)literacy development. These recommendations are based…

In the field of Instructed Second Language Acquisition (ISLA), written corrective feedback (WCF) has been shown to play a facilitative role in improving written accuracy (e.g., Ashwell, 2000; Ferris & Roberts, 2001; Ferris, 2006; Sheen, 2007; Bitchener, 2008; Liu & Brown, 2015). However, studies that examine the effects of different types…

Studies of proficient readers have shown that the use of certain strategies (e.g., relating personal background knowledge to text, attending to headings and images, and summarizing) is important for comprehension of challenging texts (Afflerbach, Pearson, & Paris, 2017; Duke et al., 2011; Goldman et al., 2016; Shanahan, Shanahan, &…

There is an ongoing debate as to whether written corrective feedback (WCF) is effective for the improvement of adult second language (L2) writers' accuracy. Ever since Truscott (1996, 1999) began arguing against grammar correction in L2 writing courses, researchers have challenged his position (i.e. below). Although most of these studies show WCF…

This study examined L2 (German) awareness in intermediate American college learners of German through their judgments of 15 texts that had been authored by either native speakers (NS) or non-native speakers (NNS) or had been created through Web-Based Machine Translation (WBMT). The specific objectives sought to investigate: (a) how learners…

This dissertation tests a grammatical structure, differential object marking (DOM), which is particularly difficult for L2 learners to acquire. DOM is a phenomenon in which some direct objects are morphologically marked to distinguish them from subjects (Comrie, 1979). In Spanish, animate and specific direct objects are marked with the preposition…
