The purpose of this study was to evaluate the effect of an intervention utilizing modified schema-based instruction (MSBI) on the mathematical problem-solving ability of elementary school students with mild to moderate disabilities. Four participants were taught to solve percent of change word problems, which required them to calculate the…

In this dissertation I explore instructors' work with instructional tasks as they plan to introduce various representations of derivatives. Drawing on the notion of "framing" from sociology, I adopt a situative lens to study calculus instructors' planning of instructional tasks. I rely on Herbst and Chazan's (2012) notion of…

Standard Spanish grammar states that desideratives ("querer que"), directives ("aconsejar que"), purpose clauses ("para que"), causatives ("hacer que"), emotive-factives ("alegrarse de que"), negated epistemics ("no creer que"), dubitatives ("dudar que"), and modals ("ser…

Although coaching has a long history guided in the apprenticeship or mentorship model (Taylor & Garratt, 2013), research has primarily focused on the athlete, rarely on the coach, and almost never on whom the coach is serving as an apprentice to, or being mentored or supported by. Internationally, this role has been termed a 'coach developer,'…

This study sought to explore whether access to definitions and general representations influences the construction of general direct arguments. Data was collected in college mathematics courses for prospective elementary school teachers. Participant arguments were analyzed along two variables: the generality of the representations and the…

The effects of fluency-based instruction and accuracy-based instruction on contingency adduction were assessed using an alternating treatments design. Stimulus equivalence tasks were used to measure contingency adduction. Stimulus classes were composed of arbitrary visual forms. One treatment condition consisted of teaching fast, fluent responding…

In the current study, we conducted a brief assessment within a multielement design to identify motivating operations (MOs) that increased or decreased the value of negative reinforcement for children with a history of challenging behavior when presented with tasks or demands. For three of the four participants, we identified specific MOs that…

Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

Language barriers in medical settings can impede access to healthcare and increase the risk of medical error for limited English proficiency (LEP) patients, especially in emergency situations (Bender et al., 2004: Martinez, 2010). Nurses who are competent in their patient's first language can decrease the risk of these issues and care more…

Touted as the future of language teaching, task-based pedagogy is grounded in current Second Language Acquisition (SLA) theories, and is in line with the trend of learner-centeredness in general education. However, the method has yet to be fully embraced by the language teaching community due to the lack of 1) clear delineation of pedagogical…

I explain changes in the wage structure favoring more skilled workers since 1980 using job task data from the Occupational Information Network and wage data from the March CPS. Using recently developed partialling out estimators including debiased machine learning, I obtain wage effects for a suite of tasks, including a novel computer task…

This study investigates the effects of native language experience and phonetic properties on the discrimination of labial-velar versus labial and velar contrasts, as well as voicing contrasts in labials, velars, and labial-velars. Research indicates that phonological perceptions are influenced by native language experience and the specific…

Verb-object idioms such as "kick the bucket" are very common in Spanish. This research set out to find what systematic differences exist between the literal and idiomatic interpretations of idioms of this kind from three different experimental perspectives: production, perception, and acceptability judgments focused on verbal aspect.…

New forms of visualizations are transforming how people interact with data. This dissertation explored how undergraduates learn with infographics. The following questions guided this research: (i) What do we know about the factors influencing the processing of data visualizations? (ii) How do task-level and learner-level characteristics impact the…

Individuals with aphasia (IWA) often exhibit challenges in single word reading as well as in reading comprehension. Recently, eye-tracking technology has become instrumental in delving deeper into reading behaviors. Specifically, it has illuminated the differences in word reading and comprehension abilities among aphasic English speakers. However,…
