McNamara received her B.A. in Linguistics from the University of Kansas in 1982, and her M.A. in Clinical Psychology from Wichita State University, Kansas, in 1989. In 1992, she earned her Ph.D. in Cognitive Psychology at the University of Colorado, Boulder. During her Ph.D., McNamara conducted research on learning theories with Alice F. Healy and reading comprehension with Walter Kintsch. She moved into educational research after receiving two grants from the James S. McDonnell Foundation to apply cognitive psychology principles to education. McNamara is the Director of the Science of Learning and Educational Technology Lab, where she and her team research and develop intelligent tutoring systems and natural language processing software. SoLET learning technologies like iSTART, a game-based tool to help readers develop self-explanation strategies, and Writing Pal, an intelligent writing tutor with game-based writing guides and automatic feedback, are free to access online through McNamara's Adaptive Literacy website. iSTART and Writing Pal are funded by the U.S. Department of Education through the Institute of Education Sciences.
Research
McNamara's research focuses on the development of intelligent tutoring systems that use game-based exercises to increase learner motivation when practicing reading and writing strategies. She developed the intelligent tutoring system Interactive Strategy Training for Active Reading and Thinking, an online application based on the idea of Self-Explanation Reading Training, which coaches learners to use active reading strategies. iSTART has been found to be as effective as live, one-on-one human tutoring of SERT in improving students' quality of self-explanation when reading. With Arthur Graesser, McNamara developed Coh-Metrix, a computational tool for evaluating text readability based on measuring levels of cohesion, world knowledge, language and discourse characteristics. Coh-Metrix has made it easier for researchers and publishers to assess text difficulty and cohesion without relying on previous methods that focused primarily on word and sentence length.
