Twenty high school physics teachers were interviewed to determine their awareness of student alternate conceptions in the areas of force and gravity. The teachers were also asked to indicate preferred teaching strategies dealing with alternate conceptions. Teacher predictions of student responses were compared to alternate conceptions held by 315 grade‐nine students and published findings from other research studies. Edmonton students were found to possess nearly every alternate conception identified in previous research, in similar proportions. A few previously undocumented alternate conceptions were also identified. At times, students were observed to arrive at the currently acceptable conclusion by using alternate conceptions. The high school physics teachers, as a group, identified nearly all the alternate conceptions used by the students. However, individual teachers were generally aware of only a few alternate conceptions, with fully one third of them possessing alternate conceptions themselves in one or more of the tasks. The teachers were also unable to predict with any accuracy the different types of student responses or the proportion of students choosing each alternative. The teaching strategies outlined by the teachers would be considered only partially effective according to current research findings.
