Erna Beth Seecamp Yackel (February 13, 1939 – September 1, 2022) was an American college professor and math educator. She was a member of the faculty at Purdue University Northwest from 1984 to 2004.

Early life and education

Erna Beth was born in Portland, Oregon, the daughter of Carsten Herman Seecamp and Ida Julia Zepik Seecamp. Both of her parents were from Canada; her father was a clergyman born in Germany, and the family lived in various rural places in Canada during her childhood. She earned a bachelor's degree at Dickinson State University in 1957, at age 18, and a master's degree in mathematics at the University of Minnesota at age 21. She later completed doctoral studies in mathematics education at Purdue University in 1984. Her dissertation was titled "Characteristics of Problem Representation Indicative of Understanding in Mathematics Problem Solving".

Career

Yackel taught statistics at Purdue while she was working on her doctorate, and for several years co-taught "Overcoming Math Anxiety", a noncredit class. She was a member of the faculty at Purdue University Northwest from 1984 until she retired in 2004. Early in her career, she won a Young Investigator Award from the National Science Foundation. She spoke at international conferences in her field. In 1992, she received the Golden Hawk Award from Dickinson State University. In 2005, she received a Distinguished Education Alumni Award from Purdue University.

Publications

Yackel published over 100 articles and book chapters in mathematics education, often on the subject of "sociomathematical norms", a concept she helped to develop. She also co-wrote a textbook on math education. Her work was published in scholarly journals including American Educational Research Journal, Journal for Research in Mathematics Education, Educational Studies in Mathematics, Educational Psychologist, The Journal of Mathematical Behavior, The Arithmetic Teacher, and Journal of Mathematics Teacher Education.

Personal life

Erna Beth married fellow academic James Yackel in 1960, while they were both graduate students in Minneapolis. They had three children, including attorney Juliet Yackel, computer science professor Jonathan Yackel, and Carolyn Yackel, a noted mathematician.

She died at her home in Dyer, Indiana on September 1, 2022, at the age of 83.
