The present study was an exploratory study of the content-specific knowledge structures of three teacher educators (two in math and one in science). Pathfinder, a method for eliciting associative memory networks, was used to describe the knowledge structures of the teacher educators. Pathfinder was also used to determine changes in knowledge structures of students enrolled in a teaching methodology class taught by each educator. Finally, a measure of the correspondence between students' knowledge structures and those of the teacher educators was correlated with students' performances in the courses. For two teacher educators, students' knowledge structures corresponded more closely with that of the teacher educator after the course than before. For one teacher educator, students exhibited little change in knowledge structure correspondence. Also, students who corresponded most to teacher educators performed better in their respective courses. The findings point to the need for further study of the acquisition of knowledge in undergraduate students and the processes associated with the transmission of knowledge in math and science teacher-education programs.
