Peter Kloosterman received a B.S. in mathematics and education from Michigan State University in 1973 and then taught high school mathematics and science before completing an M.S. (1980) and Ph.D. (1984) at the University of Wisconsin. He joined the IU faculty in 1984 and served as chair of the Department of Curriculum and Instruction from 1996 to 2001 and executive associate dean of the School of Education from 2003 to 2008. Professor Kloosterman is known for his work in the area of student beliefs and motivation in mathematics although most of his current work focuses on secondary analysis of mathematics data from the National Assessment of Educational Progress (NAEP). This work shows how performance of 4th, 8th, and 12th grade students has changed on a wide range of mathematics topics since the 1970s and how those changes correlate with changes in curriculum and policy over that period. Because this research is based on data collected from every state, recommendations for curriculum and teaching from the work are valid in schools and teacher education programs across the United States. Professor Kloosterman has been active in numerous national projects and groups, including co-chair of the student assessment group of the Research Agenda Project of the National Council of Teachers of Mathematics (2008-2009), associate editor of the Journal for Research in Mathematics Education (1991-1995), and secretary of the Special Interest Group for Research in Mathematics Education (1991-1993).
