The purpose of this dissertation is to answer the following question that falls in the intersection of philosophy of language and epistemology: is there any distinctive kind of knowledge that one might possess, merely in virtue of being a native, competent speaker of a certain natural language? When this is expressed as a question specifically…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

Early developmental skills, such as attention, language, and fine motor abilities, can be assessed in preschool to predict later achievement, particularly in reading. Connecticut Documentation & Observation for Teaching System (CT DOTS) is a holistic measure used to track the skill development of preschoolers who attend preschool programs…

Science learning is important for the well-being of individuals and society. Acquiring the knowledge necessary for success in science is not easy because science involves relational thinking, or the ability to abstract and generalize from similarities between concepts. Using relational words, or shared linguistic labels that identify commonalities…

This dissertation asks what young children do with style at a time when their social and linguistic worlds begin to expand beyond the home, into the peer group. Grounded in a yearlong ethnography of a preschool classroom in the San Francisco Bay Area, I show how play moved gradually from indoors to outdoors as children got older. This shift…

The importance of fostering in students the requisite language to understand what is being communicated and how to communicate their understanding requires educators to conceptualize themselves as teachers of language and content. It is possible to engage in activities of the mathematics classroom and through that participation engage in language…

Usage-based theories of language development underscore the importance of children using language to learn language. Few investigations have applied usage-based theories to dual language learners (DLLs), who comprise a growing share of children attending early education programs in the U.S. Three studies were carried out to investigate the role of…

An experimental crossover research design was utilized to investigate the effects of multimedia-enhanced instruction on the vocabulary acquisition of dual language learners in the early childhood age range. Sixteen 3-year-olds stratified by classroom and randomly assigned to condition participated in an eight-week intervention that incorporated…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…

The Next Generation Science Standards (NGSS) require students to use language in different ways. Expressive and receptive language skills are necessary to participate in the standards-based scientific practices of asking questions, constructing explanations, and engaging in arguments from evidence during scientific discussions. Participating in…

Children, like adults, use referring expressions to refer to specific objects, events, or people. Research has provided insights into how children use referring expressions and the appearance of forms developmentally (Radford, 1990; Abu-Akel, et al., 2004; Pine & Lieven, 1997). This study examined how three, four, and five year-old children…
