Leadership and Assistance for Science Education Reform (LASER) Model

The LASER Model is a systemic and sustainable approach for achieving high standards in science education implemented across three regions: rural North Carolina, northern New Mexico, and Houston Independent School District. The intervention was delivered at the school level to all students in participating schools over three years. Schools were randomly assigned to Phase 1 (immediate implementation beginning fall 2011) or Phase 2 (delayed implementation). The model focuses on science education reform through a comprehensive approach involving curriculum implementation, professional development, and systemic support. Students were assessed using the Partnership for Standards-based Science Assessment (PASS), which includes multiple choice, open-ended, and hands-on performance task components. The intervention targeted elementary schools (grades 3-5) and middle schools (grades 6-8) separately, with each cohort followed longitudinally.
