Dr. Tamara Kelly

Pedagogical Innovation Chair in Science Education

I teach first-year biology (ecology and evolution), second-year genetics, and a fourth-year Reproduction course and with Peter Cribb developed the first-year Integrated Science program. My post-doc with the Carl Wieman Science Education Initiative at UBC sparked a keen interest in using evidence-based inclusive pedagogy to improve my teaching, as well as investigating the alternative assessments (e.g., two-stage exams and weekly Deep Questions), collaborative learning and community in the classroom, and improving the writing of undergraduate science students from first to fourth year. I have worked to promote evidence-based pedagogy through my work on the Faculty's Committee for Teaching and Learning, development of a science-education seminar series, and a monthly science-education journal club, my work with the Open Consortium of Undergraduate Biology Educators (, and now as the Pedagogical Innovation Chair, Science Education.

If you have questions (or ideas!) about:

  • Evidence-based teaching methods
  • Research in science education or scholarship of teaching/learning
  • training/development programs for teaching and learning

Please be in touch with Tamara at

Dr. Robin Marushia

Chair, Committee of Teaching and Learning, Faculty of Science,

I earned my Master’s degree and PhD as a researcher in plant ecology and plant invasions at the University of California, Riverside, before completing a postdoc in ecology at the University of Toronto Scarborough. It is my love for teaching and outreach, however, that brought me to York as an Assistant Professor in the Teaching Stream in 2019.

To date I have taught Plant Life, Human Life (NATS 1565), Evolution (NATS 1690) and Biodiversity & Conservation (NATS 1940). My approach in teaching Natural Science courses is to provide students a foundational understanding of science as a way of thinking, while modeling science as a passion, a worldview, and a tool to solve problems. My courses are designed to be challenging within a safe environment, where all students have multiple opportunities to build on their successes while correcting their mistakes. I also incorporate aspects of experiential learning into my courses, employing personal, hands-on experience to build knowledge.

My goal is to leave students with an informed curiosity for the natural world, an ability to critically evaluate popular science media, and a dedication to action to improve the environment.
