The History Project at CSULB & DH builds partnerships between educators and scholars using research, theory, knowledge of the discipline, and best practices to deepen the quality of K12-university instruction in history-social science in the southern Los Angeles region. Education scholars offer knowledge about research and theory in discipline-based pedagogy. University historians and scholars from related disciplines provide expertise in history content, historiography, and historical practice. Classroom teachers contribute understanding of best practices in history instruction. Together these partners seek to employ inquiry approaches to learning, regularly assess student understanding, create cognitive tools to support student learning, and reflect on their own instructional practices to improve history-social science education at all levels.
