Christine D. Tippett, BASc (University of British Columbia), BEd, MA, and PhD (University of Victoria), is an associate professor of science education in the Faculty of Education at the University of Ottawa in Ontario. She was an engineer before she obtained her teaching degree, which influences her ways of thinking about science education. Previously she taught at the elementary and middle school level, working with K-8 students. Her research interests include visual representations, science education for all students, and professional development for science educators (preservice, inservice, and informal). Her current projects focus on preservice science teachers’ images of engineers, early childhood STEM education, and assessment of representational competence. She is past president of the Science Education Research Group (SERG, a special interest group of the Canadian Society for Studies in Education) and is actively involved in the Association for Science Teacher Education (ASTE).
