William Zahner

Bill Zahner is an associate professor in the mathematics department at San Diego State University and the Director of the Center for Research in Mathematics and Science Education. Zahner's research is focused on improving mathematics learning for all students, especially multilingual students who are classified as "English Learners" and students from historically marginalized communities that are underrepresented in STEM fields.

Zahner has been PI or Co-PI on multiple projects. Zahner's currently active funded projects include:

  • Principal Investigator SDSU-ELSF Classroom Research Study. Funding Agency: English Learners Success Forum, 2021-2022, $318,000
  • Co-Principal Investigator “Creating a Model for Sustainable Ambitious Mathematics Programs in High-Need Settings: A Researcher-Practitioner Collaboration.” Funding Agency: National Science Foundation (Award #2010111), 2020 - 2024, $2,527,058
  • Co-Principal Investigator “Collaborative Research: Mathematics Persistence through Inquiry and Equity: Redeveloping Gateway Mathematics in a Two-year HSI to Promote Success in STEM.” Funding Agency: National Science Foundation (Award #1953713), $2,198,757
  • Principal Investigator CAREER: Designing Learning Environments to Foster Productive and Powerful Discussions among Linguistically Diverse Students in Secondary Mathematics.” Funding Agency: National Science Foundation (Award # 1553708), 2016 - 2023, $922,263
