Using Roberts' (1982, 1988, 1995, 1998, 2003) seven science curriculum emphases as its framework, this investigation into Alberta's physics program-of-study found that pre-service and novice teachers reported focusing on four of the emphases--"Structure of Science"; "Scientific Skill Development"; "Science, Technology, and Decisions"; and "Correct Explanation"-- while experienced teachers reported focusing on two of the emphases--"Structure of Science and Everyday Coping". Other program-of-study aspects that were reported by teachers as being of high priority included holistic views of physics and student engagement, both of which fall beyond Roberts' framework. Teacher participants focused on different aspects of the program-of-study as compared to a senior curriculum leader in Alberta (i.e., the program manager for secondary sciences in the Curriculum Branch of Alberta Education), suggesting a possible need for professional development for teachers to deliver the program-of-study as intended by Alberta Education. This research increases understanding of how teachers interpret a physics program-of-study with respect to science curriculum emphases.
