The Learning Action Cell (LAC) is a professional development strategy implemented by the Department of Education (DepEd) in the Philippines to enhance teaching and learning among K-12 educators. It encourages collaborative learning, self-directed practice, and continuous improvement in teaching competencies while focusing on learner diversity and inclusion, effective pedagogy, assessment, and curriculum enhancement. The LAC process involves planning, implementation, and evaluation of educational strategies aimed at fostering a supportive teaching community.
