In this interview, Dean Zollman discusses: interests in current physics education research (PER); family background and childhood; PhD at Maryland under Carl Levinson and Manoj Banerjee; involvement in civil rights movement; postdoc at Kansas State; collaborations with Bob Fuller and Tom Campbell; involvement with American Association of Physics Teachers (AAPT); Jack Renners research on the intellectual development of college students; overview of the big names and ideas in PER in the early-to-mid 70s; research on how to meet students current developmental levels and capabilities; hands-on and visual approaches to physics learning; NSF-funded work at University of Utah, developing instructional laser discs with Bob Fuller and Tom Campbell; forays into using video for physics instruction and early application of computers to physics education; Fulbright at University of Munich; Fascination of Physics collaboration with his partner J.D. Spears; teaching quantum mechanics visually; winning the Milikan Award; the Physics InfoMall CD-ROM project; relationship with NSF; Center for Research and Innovation in STEM Education project and COVIDs damage to its realization; Oersted Medal; crossovers with field of psychology in researching how learning happens; internet-based Pathways project for high school instructors; collaborations with the International Commission on Physics Education; the excitement of helping people learn; and the hope that innovative teaching strategies will draw in a more diverse student body to solve the big physics questions of our time. Toward the end of the interview, Zollman looks forward to continuing PER both on the fundamentals of how students learn as well as on applied methods for teaching. He notes that the quest to understand the mechanisms of learning invite a more interdisciplinary approach going forward.
