Brian J. Reiser was a member of the National Research Council committee authoring the report Taking Science to School (2007), which provided research-based recommendations for improving K-8 science education. Reiser worked with the NRC committee to develop the Framework for K-12 Science Education (2012), which guided the design of The Next Generation Science Standards (NGSS), and Developing Assessments for the Next Generation Science Standards (2014) which provides guidelines for NGSS assessments. Reiser has also worked with Achieve to provide feedback on the design of NGSS and on the tools to help states implement NGSS, and is collaborating with several state initiatives to design and provide professional development for K-12 teachers to support them in realizing the reforms in NGSS in their classrooms. Reiser's research examines how to make the scientific practices of argumentation, explanation, and modeling meaningful and effective for classroom teachers and students. Reiser co-led the development of IQWST (Investigating and Questioning our World through Science and Technology), a three-year middle school curriculum that supports students in science practices to develop disciplinary core ideas.
