The John S. and James L. Knight Foundation, through its Excellence in Education Program, has sponsored a number of collaborative efforts involving schools and higher education institutions in the United States. One of these, Mathematics Pathways, involved a local university and community college working together with the school system to bring about improvements in the teaching and learning of mathematics at all levels. The work involving teachers and students from schools has been particularly productive. Students involved in the Mathematics Pathways project have shown significant improvement in mathematics as compared with students not involved in the project. The collaborations have proved to be beneficial to all participants.
