Scientific knowledge is advanced because scientists manage uncertainty. Although managing uncertainty is an essential practice of science, transferring it from expert settings to K-12 classrooms is problematic because, understandably, students are not familiar with the intentions of scientists. Few studies have explored learning science as an…

An experiment examined orthographic facilitation of vocabulary learning, that is, whether showing students spellings of novel words during learning helps them remember the words when spellings are no longer present. The purpose was to determine whether having students decode the spellings of vocabulary words improves word learning over passive…

Purpose: Extant research indicates that children and adolescents with autism spectrum disorder (ASD) without an intellectual disability (ID) often experience difficulty comprehending written texts that is unexpected in comparison with their cognitive abilities. This study investigated the development of two key skills, narrative and inference…

Purpose: The purpose of this study was to examine the extent to which phonological competition and semantic priming influence lexical access in school-aged children with cochlear implants (CIs) and children with normal acoustic hearing. Method: Participants included children who were 5-10 years of age with either normal hearing (n = 41) or…

The aim of the present work was to investigate the processing of coreferential relations, focusing on their relationship with the working memory. In a reading process, it is essential that readers continuously perform mental operations that involve the working memory, such as storing, retrieving, and manipulating information. For this reason, it…

Learning to paraphrase supports both writing ability and reading comprehension, particularly for less skilled learners. As such, educational tools that integrate automated evaluations of paraphrases can be used to provide timely feedback to enhance learner paraphrasing skills more efficiently and effectively. Paraphrase identification is a popular…

Stance is a feature of academic writing that refers to how writers interact and engage with their readers by means of linguistic devices. This study focuses on the grammatical devices--and semantic distinctions thereof--that are employed by academic writers of English to express stance in research article abstracts in the areas of applied…

The ability to automatically assess the quality of paraphrases can be very useful for facilitating literacy skills and providing timely feedback to learners. Our aim is twofold: a) to automatically evaluate the quality of paraphrases across four dimensions: lexical similarity, syntactic similarity, semantic similarity and paraphrase quality, and…

The present dissertation investigated the impact of scales/scoring methods and prompt linguistic features on the measurement quality of L2 English elicited imitation (EI). Scales/scoring methods are an important feature for the validity and reliability of L2 EI test, but less is known (Yan et al., 2016). Prompt linguistic features are also known…

The processing of structurally ambiguous sentences has proven resourceful in understanding the human parser. In particular, the resolution of globally and temporarily ambiguous relative clauses (RC) preceded by a complex noun phrase (NP) such as "Someone shot [the servant]NP1 of [the actress]NP2 [who was on the balcony]RC" has been found…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…

Source-based writing is a complex and frequently occurring task type in postsecondary education. While a large body of research now exists investigating source-based student writing, few studies have used corpus-based methods to investigate L1 student performance on source-based writing tasks and to connect this performance to the holistic quality…

The present study investigates native (L1) and second language (L2) processing of scope ambiguities in English sentences containing the universal quantifier every in subject NP and negation. Previous studies in L1 and L2 processing of scope ambiguities have found speakers to generally employ a 'minimal effort' principle that highly prefers the…

Scalar implicatures involve inferring the use of a less informative term (e.g. some) to mean the negation of a more informative term (e.g. not all). A growing body of recent research on the derivation of scalar implicatures by adult second language (L2) learners shows that while they are successful in acquiring the knowledge of scalar…

The role of context in cloze tests has long been seen as both a benefit as well as a complication in their usefulness as a measure of second language comprehension (Brown, 2013). Passage cohesion, in particular, would seem to have a relevant and important effect on the degree to which cloze items function and the interpretability of performances…
