The LASER (Leadership and Assistance for Science Education Reform) model, developed by the SSEC, is a systemic approach to transforming science education consisting of five elements: a research-based, inquiry-driven science curriculum; differentiated professional development; administrative and community support; materials support; and assessment. These elements, when planned around a shared vision for science, form the infrastructure to sustain student-centered learning and teaching. "LASER i3" refers to the longitudinal study of the LASER model conducted by the Center for Research in Educational Policy (CREP) at the University of Memphis. The evaluation studied approximately 60,000 students attending public elementary and middle schools (urban, rural, and suburban), 20.9% of whom were enrolled in eight school districts in northern New Mexico. [Additional funders for the SSEC LASER i3 study include the JP Morgan--National Philanthropy Trust and Teresa Bergeson.]
