Rebecca Callahan is professor in the College of Education and Social Services at the University of Vermont. Her primary research interests center on the academic experiences of immigrant-origin, language-minority adolescents as they transition from high school into young adulthood. She is presently involved in several research projects that explore the effects of school context; social and academic processes; and teachers' pedagogical practices on the academic and civic development of immigrant-origin, potential-bilingual students. She also examines the effects of English as a second language (ESL) placement on college preparatory achievement outcomes among language-minority adolescents; primary language use and college-going among language-minority students; and school context and academic preparation on the political participation of immigrant young adults. Callahan received her PhD in education from the University of California, Davis.
