The purpose of the Increasing Diverse Learner Engagement and Achievement (IDLEA) project is to increase engagement among Colorado’s diverse learners in order to address the ongoing challenges of the COVID-19 pandemic and help close the achievement gap between these learners and their peers. To accomplish this, 14 schools throughout Colorado have worked with the Colorado League of Charter Schools, professional development providers, and Apex as the research and evaluation partner. In collaboration with the 14 cohort schools, Apex created surveys for students, teachers, and school administrators to measure student engagement across three domains – behavioral, cognitive, and emotional. Survey results and mental models were compared across each group and diverse learner categories. Apex shared school-level reports and facilitated conversations with school leaders to expand their understanding of student engagement and identify possibilities for improving engagement among their diverse students.
