The document describes the ELLN Digital blended professional development course for K-3 teachers. It aims to improve early literacy and numeracy instruction. The course has self-study and collaborative learning components. Teachers study online lessons and meet in school-based Learning Action Cells (LACs) to discuss lessons. LACs are formed with 5-15 teachers facilitated by a LAC Leader. LAC sessions involve sharing assignments, group discussions, and planning next steps to apply learning in classrooms. Feedback is gathered through teacher reports and facilitator reports to evaluate the program.
