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…

Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean.

Reclassification is a crucial educational student outcome when a school system determines that a student is English proficient and ready for mainstream instruction without language support services (Umansky et al., 2020). This study examined the relationship between crucial and complex language ideologies of dual language teachers and the…

Orthography-phonology mapping in world languages exhibits variations. Extensive research has investigated whether orthographic-phonological consistency impacts the cognitive processing of written words. A major body of work has focused on the recognition of phonographic first language (L1) written words. Results show that the more transparent the…

As the world faces increasingly complex issues, there is a recognition in many disciplines that the existing paradigm of reductionist and linear thinking is not enough to address these issues. The agriculture, food, and natural resources fields are facing a host of issues that defy solutions in part because of the level of complexity. Systems…

The tendency for negation to appear early in the sentence, dubbed the "Neg-First principle" by Horn (1989:452), has been observed in the domains of typology, language contact, and language acquisition. Based on evidence from these fields, scholars have speculated about the source and universality of Neg-First biases affecting language…

The purpose of this meta-analysis was to investigate the effectiveness of the use of games as part of mathematics instruction on academic achievement in grades Kindergarten to 12 in the United States.

Discourse markers (DMs) are linguistic forms characterized by their use as conversation organizers or pause fillers (Fox Tree, 2010). Although used frequently in both speech and writing, DMs are not often taught in L2 classrooms, despite incorrect usage causing potential misunderstandings (Polat, 2011). Additionally, L2 learners have been observed…

Given the literature review on over and under representation of ELL students in Special Education, this research aimed to study how teachers identify between ELL students who present with language proficiency learning difficulties and students who might exhibit learning disabilities.

This research aims at deconstructing and questioning certainties about assessment as an educational institution on its most fundamental levels. To achieve that, I am utilizing theoretical frameworks inspired by concepts on the existence of cultural and social capital, by artifact mediated cognition, and by a recently proposed discipline on…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

This dissertation examines current science education reforms by asking how it became historically possible to classify students, diagnose their differences, and prescribe distinct pedagogies in the name of inclusion. Through historicizing present pedagogical practices, the study explores how science education carries assumptions of human…

This dissertation, presented as two studies, seeks…
