An innovative new project that leverages machine learning to assess mathematics lesson plan quality in the middle grades has been selected by the National Science Foundation (NSF) to receive a $1.5 million grant. Through this project, a cross-university research team led by principal investigator Dr. Min Sun of the University of Washington College of Education will identify ways to measure the quality of large quantities of open-source mathematics lesson plans using an integration of cutting-edge machine learning techniques, knowledge of effective mathematics education and human feedback.
