After completing his PhD in chemistry at Cambridge University, John Haysom taught science in a variety of schools before becoming a member of the faculties of education at five universities: Oxford University, Reading University (UK), University of the West Indies, Mount Saint Vincent University (Canada) and Saint Mary’ s University (Canada), where he is Professor Emeritus. John has gained an international reputation as a teacher-educator and curriculum developer. In the UK, he was the coordinator of the groundbreaking Science Teacher Education Project, funded by the Nuffield Foundation. This was probably the first teacher education curriculum project in the world and was adapted for use in Australia, Canada, Israel, and other countries. At the University of the West Indies, he was responsible for the design and implementation of an innovative, theme-based inservice B.Ed. curriculum. As professor of education at Saint Mary’ s University, he initiated and helped lead the Atlantic Science Curriculum Project’ s SciencePlus textbook series. This curriculum was highly rated and became widely adopted in the United States. He has acted as a science curriculum consultant to the government of Trinidad and Tobago and to a number of projects in the United States. John is the author of many books for teacher educators, teachers, and schoolchildren, as well as academic papers in curriculum design, evaluation and implementation, and teacher education. His most recent work includes Predict, Observe, Explain: Activities Enhancing Scientific Understanding (with Michael Bowen; NSTA 2010) and “ Science Curriculum Research and Development in Atlantic Canada: A Retrospective,” an article prepared for the Canadian Journal of Science, Mathematics and Technology Education (in press). John has long been interested in science fairs, both as a teacher and a judge, and was elected to the board of directors of the Youth Science Foundation, the national body responsible for science fairs in Canada.
