In 2019, Dr. Lindsay Brown at New York University’s Global TIES for Children (NYU-TIES) co-developed and implemented the Building Expert Teachers Through Evidence-based Research (BETTER) program with Laura Killips. BETTER is designed to support intentional and sustained teacher learning across contexts. It utilizes practice-based strategies to develop teachers’ foundational skills and knowledge and to sustain them with the support of teacher coaches and other resources within education systems. The program builds upon decades of scientific research that demonstrates that effective professional development: demands active and applied learning from its participants; provides sustained and repeated learning opportunities; showcases models of effective practice; provides expert support; and fits within a coherent framework of practice.
