Education
She attended the local Methodist college for two years and then transferred to Kansas State University where she majored in psychology. She received her master"s degree in education from the University of Wisconsin in 1952.
In 1962 Kathryn Clarenbach (a founder of National Organization for Women) sent out a questionnaire inquiring of unemployed or underemployed wives of university professors who were interested in a career. As a result of this process Fennema was asked to be a supervisor of student teachers.
In this positions she worked for Vere DeVault who encouraged her to pursue a doctorate in education and served as her dissertation adviser.
She began in 1962 and received the degree in 1969 in curriculum and instruction in mathematics education. In 1962 "new math" was in vogue and many educators were thinking deeply about how to teach mathematical understanding to students.
Fennema recognized the importance of a good foundation in mathematics was critical for all students leading to her interest in math education.
Career
After finishing her Doctor of Philosophy she was hired as a half time, non-tenured track, position. In 1970 the University created part-time tenured-track positions and Fennema obtained one of the positions. Fennema and Julia Sherman applied for a grant from the National Science Foundation (National Science Foundation) research grant to examine factors in mathematics classroom that might be associated with gender, resulting in the "Fennema-Sherman studies".
Fennema and her associates have spent over 25 years researching interactions of girls and young women in mathematics classrooms.
One outgrowth of this was a questionnaire, the "Fennema-Sherman Scales" to enable researchers to gather data on the attitudes of young women towards mathematics, and the results from different sites compared. She and her colleagues have also developed an innovative method of teaching mathematics called Cognitively Guided Instruction.
The Cognitively Guided Instruction (Consultants to Government and Industry) philosophy is detailed in Children"s Mathematics which she co-authored with Thomas Carpenter, Megan Loef Franke, Linda Levi, and Susan Empson. Fennema retired from the University of Wisconsin at the end of the 1995-1996 academic year.
