This conference seeks to improve how teacher preparation programs equip educators to engage families in preK-5 children’s math learning by bringing together math teacher educators, preK-5 classroom teachers, families/caregivers, and mathematics teacher candidates. The conference topic is important because while family engagement in mathematics is highly predictive of children’s mathematical outcomes, teachers’ family engagement responsibilities are rarely addressed in teacher preparation programs. Beginning with an in-person gathering and followed by two virtual workshops, the conference will elevate models of community-engaged mathematics teacher preparation and explore the competencies that elementary grade teachers must develop to meaningfully engage families in mathematics. By highlighting the voices of families, pre- and in-service teachers and university faculty, the project ultimately seeks to strengthen family-school partnerships, foster success in math and STEM careers for all students, promote the progress of science, and support the nation’s prosperity by fostering inclusive and equitable educational practices. The proposal is supported by the Discovery Research preK-12 program (DRK-12), an applied research program that seeks to significantly enhance the learning and teaching of science, technology, engineering, and mathematics (STEM) by preK-12 students and teachers. Projects in the DRK-12 program build on fundamental research in STEM education and prior research
