This dissertation focuses on strategies and techniques to enhance code comprehension skills among students enrolled in introductory computer science courses (CS1 and CS2). We propose a novel tutoring system, "DeepCodeTutor," designed to improve the code comprehension abilities of novices. DeepCodeTutor employs scaffolded self-explanation…

Language comprehension requires a complex series of decisions under uncertainty. This is especially obvious when one string may have multiple different interpretations, whether due to lexical ambiguity, or the potential for an inference beyond literal content. This dissertation profiles how the human system for language comprehension times those…

Meaning construction is a complex concept that encapsulates language and thought as a whole system in which sense and meaning have a unique relationship highly marked by the social and cultural environment of the reader. Hence, Kichwa-Spanish bilinguals' reading practices in the Southern Andes of Ecuador cannot be discussed as two separate…

Emojis are nonverbal elements used in text-based communication that may function like gestures in spoken communication (Feldman et al., 2017; McCulloch & Gawne, 2018). Like words, emojis can convey semantic information and support message comprehension (Lo, 2008; Riordan, 2017b). Nevertheless, the cognitive and perceptual processes involved in…

Psycholinguistic research aims to understand how people make sense of language in their everyday lives. However, most of this research studies language under experimental conditions in which people are instructed to specifically monitor (and indicate) when there is a breakdown in their understanding. Moreover, there is an assumption that people…

Arabic orthography is mainly presented either in shallow orthography (with all diacritics) for novice students or in deep orthography (without diacritics) for superior readers. However, the shallow orthography is heavily loaded with diacritics which may burden the reading process, whereas deep orthography can cause ambiguity (heterophonic…

This dissertation investigates the ways that natural languages evolve and what it means in the overall cultural evolution of society. Computational and modeling advances have made possible to explore large-scale text data and test hypothesis of language evolution. Similar to biological systems, natural languages are evolving systems with words as…

Reading comprehension can be analyzed from three points of view: Semantics, Assessment, and Cognition. Here, Semantics refers to the task of identifying discourse relations in text. Assessment involves utilizing these relations to obtain meaningful question-answer pairs. Cognition means categorizing questions according to their difficulty or…

The vocabulary deficit shown by English Learners (ELs) has become evident among many educators over decades of research (Becker, 1977; Biemiller, 2001; Chall, Jacobs, & Baldwin, 1990; Hart & Riseley, 2003), and has shown that a student's limited vocabulary becomes a "major barrier to school success" (Graves, 2005, p. 18).…

Semantic illusions are recognition errors that occur when an individual fails to notice that information contradicts their prior knowledge (Barton & Sanford, 1993; Erickson & Mattson, 1981). For example, after hearing the question, "If a plane crashes while flying over state lines, where should the survivors be buried?" many…

Language comprehension is remarkable in that we adapt easily to different forms of language use, from adapting to speakers' dialects, meanings of new slang words, and fictional worlds described in novels. While there is growing evidence comprehenders adapt their expectations for text during reading, the nature of these adaptation mechanisms…

The representational product of sentence comprehension is the result of the interplay between episodic and semantic memory and our knowledge of the grammatical devices of our language which guide how we retrieve information from these systems. Past participles, being a part of speech derived from verbs but used in a prenominal position (e.g. words…

High level reading comprehension is a process that results in a reader's semantic interpretation of a text, or mental model of that text, referred to as the "reader's situation model." Individual differences in readers' verbal working memory resources, as measured by reading span tasks (RST), and operation span tasks (OST), have shown to…

Uganda Baptist Seminary (UBS) is accredited by the Ugandan National Council for Higher Education and teaches church leaders from Uganda and its surrounding seven countries. The required language of educational instruction is English, although the students come from a multitude of different native languages. This research stems from a need to…

Researchers have investigated that different dimensions of word knowledge (breadth versus depth) may play distinct roles in second language (L2) reading comprehension. Yet, little research has addressed how learners' efficiency of accessing those dimensions of knowledge functions in their comprehension (i.e., the issue of knowledge availability…
