Fredchen Keller was an Austrian-born American psychologist who made significant contributions to the field of behavior analysis. She is best known for her work on Keller's Personalized System of Instruction (PSI), a method of teaching that emphasizes self-pacing and mastery learning. PSI has been shown to be effective in a variety of educational settings, from elementary schools to universities.

Keller was born in Vienna, Austria, in 1916. She emigrated to the United States in 1938 to escape the Nazi regime. She earned her PhD in psychology from Columbia University in 1952. After graduation, she worked as a research psychologist at the University of Kansas and the University of WisconsinMadison. In 1965, she joined the faculty of Arizona State University, where she remained until her retirement in 1991.

Keller's work on PSI began in the early 1960s. She was dissatisfied with the traditional lecture-based approach to teaching, which she felt did not allow students to learn at their own pace or to master the material. PSI is a self-paced learning system that allows students to progress through the material at their own rate. Students are given a series of learning units, each of which covers a specific topic. They work through the units at their own pace, and they are tested on each unit before they can move on to the next one. PSI has been shown to be effective in a variety of educational settings, from elementary schools to universities.
