Professor Bryan's research program and scholarship focus on teacher thinking in the process of learning to teach science. She uses case study and interpretive methods to conduct in-depth, longitudinal studies of teacher thinking (beliefs and knowledge) as it relates to classroom actions. Professor Bryan's scholarship draws on a coordinated cognitive and sociocultural perspective. Specifically, her research may be characterized by the contexts in which her work takes place: (a) instructionally innovative settings involving novel curriculum reform and technology-enhanced environments, and (b) culturally and linguistically diverse settings.

  • Science teacher thinking in instructionally innovative settings: Nanoscale science education. Professor Bryan's research in nanoscale science education focuses on teachers' development of knowledge for teaching nanoscale science in middle and high school classrooms. Specifically, her research group is investigating middle and high school teachers' knowledge of concepts, causal networks, and explanatory structures of nanoscale phenomena including size and scale, structure of matter, size-dependent properties, forces and interactions, self-assembly, models and simulations and tools and instrumentation.
  • Science teacher thinking in instructionally innovative settings: Physics curriculum reform. This project involves research on the large scale, multi-institutional implementation of a revolutionary course, Matter and Interactions (M&I), in the undergraduate physics curriculum.
  • Science teacher thinking in instructionally innovative settings: Technology enhanced environments. Professor Bryan is interested in using novel technologies to enhance not only teachers' reflective thinking but also student learning. For example, in her recent work with M&I physics TA's, Professor Bryan is infusing a Web-based video analysis tool, VAT (, into the TA preparation experiences at Purdue. Professor Bryan also has conducted research on the use of this tool to promote reflective thinking in preservice teacher education courses.
  • Science teacher thinking in culturally and linguistically diverse settings. Professor Bryan has collaborated with faculty from the University of Georgia, Benemérita Escuela Normal Veracruzana, and rural schools in Veracruz, Mexico. Her research in rural Mexican classrooms predominantly has focused on teachers' knowledge for promoting social discourse practices in their classrooms that mediate their students' transitions between science, school, and community contexts. Currently, Dr. Bryan is collaborating with the Jiangsu Institute of Education in Nanjing, China to conduct research and engagement activities in the rural schools of Wuxi, China. With funding from a Purdue University Asian Initiative Grant, Professor Bryan and faculty at JIE established the Sino-American Center for Science Education Research and Engagement at the Jiangsu Institute of Education in Nanjing, China in November 2006.
