Interpersonal interactions between teachers and students are a site where students may encounter negative experiences with mathematics; they are also a site where students can experience mathematics in empowering and positive ways.

The present dissertation discusses the importance of rootedness, defined as orientation towards place, and how it factors into sociolinguistic studies. Although rootedness is not a new concept in sociolinguistics, it has been infrequently operationalized to understand its role in language change. Linguists have discussed concepts similar to…

Even though engineering and science are tasked with developing solutions and knowledge for a diverse population, Black and Brown communities remain severely underrepresented in these disciplines. The problem exceeds easy solutions like "a seat at the table" and requires rethinking with whom and for whom the field designs ideas and…

The recent theoretical debate over the role of translanguaging in dual language programs can be described as moving from prohibition to promotion. Indeed, many researchers, theorists, and educators are now encouraging translanguaging. At the center of the debate are teachers and their beliefs, which some argue influence their practice.

The study of language contact epitomizes the dynamics of language as a system of human communication. The competing linguistic forces at work when speakers of different language varieties come into contact can be narrowed down to two basic concepts--convergence and divergence. Looking at linguistic areas using a macro approach, languages in…

As the Greek verbal system has become the subject of various dissertations and monographs, the future tense-form has been generally overlooked in the discussion. This dissertation seeks to overcome this lacuna by suggesting that the future tense-form functions as a rhetorical feature that expresses the author's expectation of an alternative state…
