Edward Lyon is an Assistant Professor of Science Education in the School of Education at Sonoma State University. He was formally Assistant Professor of Science Education at Arizona State University. Dr. Lyon conducts K-12 science education research to understand how core instructional and assessment practices enhance learning for ELs, including how science teachers are prepared to enact those practices. Dr. Lyon’s dissertation work, exploring the development of pre-service science teachers’ expertise at ambitious assessment received a $20,000 UC-ACCORD Dissertation Fellowship, the 2012 Outstanding Dissertation Award from the California Council of Teacher Education, and the 2013 NARST Outstanding Paper Award. Dr. Lyon is currently engaged in two primary research projects. He is Co P.I. on the NSF DR K-12 Secondary Science Teaching with English Language and Literacy Acquisition (SSTELLA) project to study the impact of a teacher education model on novice science teachers' beliefs, knowledge, and practice of teaching science to ELs. He is also P.I. of the Ambitious Assessment in Secondary Science classrooms (AASC) Project funded by a Mary Lou Fulton Teachers College Internal Grant and a Fulton Scholars Challenge Award to refine research tools and a conceptual framework for assessing science in secondary science classrooms with ELs. Dr. Lyon formally taught biology and chemistry for in culturally and linguistically diverse high schools.

Jorge L. Solis (Ph.D. in Language, Literacy & Culture, University of California, Berkeley; Public Policy from Stanford University) is a tenure-track Assistant Professor in the Department of Bicultural-Bilingual studies in the College of Education and Human Development at the University of Texas at San Antonio (UTSA). Jorge is firmly committed to improving the schooling prospects and achievement of all students through the production and sharing of practical and innovative research. Dr. Solis’ research interests in bilingual studies and English language learner education involves examining a range of teaching and learning contexts from children in elementary classrooms to secondary school adolescents as well as the study of experienced and novice classroom teachers. Much of this work focuses on understanding the academic transitions of English language learners across into secondary school. His ongoing research on novice teacher education aims to understand how beginning teachers can take-up more authentic sociocultural and disciplinary approaches that use language and literacy practices to advance content comprehension in linguistically diverse classrooms. Ten years of research involving in-service and pre-service teachers in elementary classrooms contexts has focused on science instruction with English Language Learners (ELLs) across varied language programs. Dr. Solis’ recent work in San Antonio expands on this work by examining secondary school contexts where novice teachers possess much stronger scientific knowledge expertise yet with much more varied familiarity with pedagogical language knowledge. He is the UTSA principal investigator of the National Science Foundation DRK-12 funded SSTELLA project examining higher education education reform for science teachers in linguistically diverse classrooms. Through this new research, Dr. Solis hopes to provide more effective teacher education models for secondary school teacher education programs that addresses the science learning contexts of adolescent English language learners in bilingual, mainstream, and ESL classrooms. Jorge has presented his work at the American Educational Research Association, American Anthropological Association, National Association for Research on Science Teaching, and National Association for Bilingual Education. His work has been published in Linguistics and Education, Issues in Teacher Education and has been recognized in the Review of Research in Education and several edited volumes. Jorge has taught education courses to undergraduates, elementary and secondary teacher credential students, and doctoral students on issues of bilingualism, classroom discourse, disciplinary literacy and second language literacy, and English-language development. Previous or current courses he teaches at UTSA include: BBL. 6063:Research Methods in Bilingual & Second Language Studies, BBL 5033: Bilingual Content Instruction, BBL 7223: Seminar in Biliteracy & Second Language Literacy, BBL 4353: Approaching to Teaching Science EC-6, and BBL.3053: Foundations of Bilinguals Studies.

Sara Tolbert is Assistant Professor of Science Education in the Teaching, Learning, & Sociocultural Studies Department at the University of Arizona’s College of Education. Dr. Tolbert received a Ph.D. in Education from the University of California at Santa Cruz in 2011. Dr. Tolbert’s research focuses on redesigning science teacher education as a vehicle for improving English learners and other minoritized students’ opportunities to learn relevant and contextually authentic science, and on facilitating social change and youth leadership through school science. Before pursuing her graduate degrees, Dr. Tolbert taught science and sheltered science in formal and informal settings in the South Bronx, NY, Atlanta, GA, South Auckland (Papatoetoe), New Zealand, and Latin America. 

Dr. Tolbert has been a member of TEEL since 2006, serving as graduate research associate on the Institute of Education Sciences grant Integrating Science and Diversity Education: A Model of Pre-Service Elementary Teacher Preparation, and the NSF grant Effective Science Teaching for English Language Learners (ESTELL), and Co-PI on the NSF DR-K12 project, Secondary Science Teaching with English Language and Literacy Acquisition. Her latest publication is titled "Because they want to teach you about their culture…”: Analyzing effective mentoring conversations between culturally responsible mentors and secondary science teachers of indigenous students in mainstream schools, published in the Journal of Research in Science Teaching.

Key Collaborators

George Bunch's research focuses is on language and literacy challenges and opportunities for language minority students in K-12 and higher education, and on policies and practices designed to serve such students. I am also active in efforts to prepare teachers for working with English Learners. 

I recently served on the English Learner Advisory Panel for the California Commission on Teacher Credentialing, and I am a founding partner of the Understanding Language Initiative (, formed to heighten awareness of the role of language for English learners as new common core standards are implemented throughout the United States. 

Prior to my research and teacher education career, I taught high school ESL, social studies, and Spanish in Maryland and Washington, DC.

Areas of interest: Education of language minority students in US schools; language and literacy for academic purposes; language policies and practices in community colleges; preparation of K-12 teachers for linguistic diversity; second language acquisition; bilingualism.
