CSE, through a cooperative agreement with the NSF, is establishing and maintaining the Discovery Research K–12 learning resource network, known as CADRE. The goals are to advance the state of research and evaluation in STEM education and to move forward the goals of the DR-K12 program. CADRE provides support services to grantees from the DR-K12 program, which enhances student and teacher learning of the STEM disciplines through the development, implementation, and study of resources, models, and technologies.
