Between 2002 and 2013, the Institute of Education Sciences (Institute) funded over 300 projects focused on math and science. The majority of this work has been funded through Mathematics and Science Education research topics of the National Center for Education Research (NCER) and the National Center for Special Education Research (NCSER). Both centers also support projects focusing on math and science through other research topic areas, including programs such as Cognition and Student Learning, Early Learning Programs and Policies, Educational Technology, and Teacher Quality. Together, researchers funded by NCER and NCSER have developed or tested more than 215 instructional interventions (e.g., packaged curricula, intervention frameworks, and instructional approaches), 75 professional development programs, 165 educational technologies, and 65 assessments in math and science. In addition, they have published over 850 peer-reviewed articles and reports based on these projects thus far.
