Description:
This presentation showcases one school’s journey towards capacity building and strengthening its commitment to multilingual learners’ linguistic and academic achievement. By focusing on the implementation of the SIOP Model, a recognized and effective, research-based instructional model which benefits linguistic and academic achievement for multilingual learners, this school built a three-year professional development plan to improve teacher capacity. When supported through a long-term, job-embedded approach featuring guided lesson design and lesson study, results are noted in improved teacher evaluations and boosts in student achievement and language proficiency levels. The school’s PD plan and tools are shared and discussed.
