Teachers at HLA are committed, intelligent, hard-working educators who must focus all of their energies on the children in their classrooms. But they need support as well in order to continually hone their teaching skills. In a traditional school setting, teachers would get this support by enrolling in what we describe as “drive-through” professional development through workshops, seminars and courses that either take them out of the classroom and/or consume their preparation time during after-school and weekend hours. At HLA, we want to keep teachers focused on their primary purpose: teaching in the classroom. So, we provide on-the-job training and support directly within the classrooms. Our Directors of Curriculum and Instruction, for both general studies and Hebrew, work directly with teachers in their classrooms to bring leading edge curricular and instructional approaches to them. We also bring in experts in specific educational practices such as use of Critical Friends Groups and data-driven decision making to provide additional embedded professional development to both our Directors and teachers.
