Xin is a Senior Research Associate at RMC Research and serves as co-principal investigator (co-PI) for two National Science Foundation (NSF)-funded projects. The first is a DRK-12 project, Student-Adaptive Pedagogy for Elementary Teachers: Promoting Multiplicative and Fractional Reasoning to Improve Students’ Preparedness for Middle School Mathematics (AdPed) and the second is focused on developing an innovative computer simulation environment to facilitate learning of biology using dynamic systems approaches (University of Nebraska-Lincoln IUSE). This project aims to transform the way biology students learn about complex living systems by developing, implementing, and evaluating computational modeling as a unique and user-friendly pedagogical aid. Xin is leading the formative and summative evaluation efforts by developing instruments for data collection, validating the instruments/measures, collecting and analyzing data from participant interviews and/or focus groups, surveys, project documents, and classroom observations, and working with the project team to use results for improvement of the project. Xin received her MA from the University of Illinois at Urbana-Champaign, Division of English as an International Language, Teaching English as a Second Language, and her PhD from the University of Illinois at Urbana-Champaign, in Educational Psychology.
