ABSTRACT DISSERTATION TITLE: How do pre-service teachers picture various electromagnetic phenomenon? A qualitative study of pre-service teachers' conceptual understanding of fundamental electromagnetic interaction. STUDENT: Christopher P. Beer DEGREE: Doctor of Education COLLEGE: College of Sciences and Humanities DATE: December, 2010 PAGES: 398 This study analyzes the nature of pre-service teachers’ conceptual models of various electromagnetic phenomena, specifically electrical current, electrical resistance, and light/matter interactions. This is achieved through the students answering the three questions on electromagnetism using a free response approach including both verbal and pictorial representation. The student responses are then analyzed qualitatively and quantitatively utilizing a multi-tiered approach. These analyses include epistemological representation, misconceptions, correct conceptions, and the impact of high school physics exposure on student conceptions. This study is unique in three primary respects; the free response iv questionnaire approach, a subject group that consists of pre-service teachers, and a primarily female demographic. v
