This paper describes strategies employed by 49 secondary mathematics teachers on inferential reasoning tasks with special attention to randomization approaches. The participating teachers engaged in a year-long professional development program and experienced activities spanning the secondary content standards specific to probability and statistics widely adopted throughout the United States including randomization approaches to inferential tasks. Pre- and post-assessment data were collected to gauge resulting changes in teachers’ content knowledge from two sources: GOALS-2 and five research-based constructed-response items. We characterize the strategies teachers demonstrated on post-assessment inferential reasoning tasks and note changes in strategies from pre- to post-assessments. Lastly, we discuss implications for professional development efforts specific to secondary mathematics teachers.
