| 英文摘要: | In 2011, the Bill & Melinda Gates Foundation created the Project Mastery grant program to support competency-based education initiatives in large school systems that serve a high proportion of disadvantaged youth. Competency-based education meets students where they are academically, provides students with opportunities for choice, and awards credit for evidence of learning, not for the time students spend studying a subject. The Foundation asked RAND to evaluate these efforts in terms of implementation, students' experiences, and student performance. This report presents final results from that evaluation, offering an overview of competency-based education and the Project Mastery grant projects and describing the implementation of competency-based educational features under each project. The report concludes with six lessons for policy, partnerships, and practice. |
