Jechun An, PhD

Hi! I am a Postdoctoral Scholar at Stanford University. Before joining academia in the United States, I began my career as a tenured elementary school teacher in a rural area of South Korea (2016-2018). I also earned an M.A. from Seoul National University (2020). Until 2024, I served as the lab manager for the federally funded Early Writing Project, which provided professional development for elementary teachers in implementing data-based individualization (DBI) to support students with writing difficulties. In 2024, I earned my Ph.D. from University of Minnesota Twin-Cities. After graduation, I served as a Post-Doctoral Associate at the Department of Educational Psychology, University of Minnesota, Twin-Cities (2024-2026). My major role was managing the data for two federally funded (Institute of Education Sciences; IES) projects that entail large-scale efficacy trials of educational technology focusing on literacy and mathematics.

Research

My research focuses on integrating literacy assessment into data-informed instructional systems to support teachers working with students who experience significant difficulties in literacy (reading and writing) and language. Ultimately, My research goal is to develop equitable and instructionally useful approaches that improve literacy outcomes for diverse learners. My recent works explore:

• Instructionally Useful Assessment: An (2024)
• Personalized Learning Paths: An et al. (2026)
• Coaching Support for Teachers: An et al. (2025), An & McMaster (2026)
• Effectiveness of Instruction/Intervention: An & Kim (2025), An, Choi, and Lim. (2025)
