The third edition of the Educating the Educators conference series is now only a couple of months away and we are excited to present the program schedule to you! On October 7-8, 2019, researchers, teacher educators, STEM PD centres, policy makers and business representatives from around the world will gather at the University of Education in Freiburg, Germany, to help reshape the future of STEM education. This conference will provide an innovative space for fruitful exchanges around a common question of these diverse groups: how do we best scale up professional development (PD) in maths and science education?
