Given the increasing number of multilingual learners enrolled in U.S. secondary schools and persistent disparities in access to quality STEM education for these students, teacher education programs must prepare secondary science teachers capable of teaching multilingual learners in equitable ways. There is a consensus in science education…

This dissertation investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

Translanguaging, an emergent theoretical orientation to language, has become a widely discussed topic in writing studies with the rise of translingual movement in composition. Challenging the ideologies of standardization and monolingualism, translanguaging forwards towards a pedagogy of difference and facilitates transcending the…

This dissertation describes the phonetic characteristics of a phenomenon that has previously been denominated "unstressed vowel reduction" in Andean Spanish based on the spectrographic analysis of 40,556 unstressed vowels extracted from the conversational speech of 150 residents of the city of Cusco, Peru. Results demonstrate that this…
