Core Knowledge is an educational framework that emphasizes the importance of a shared body of knowledge for all students. Developed by E.D. Hirsch, it aims to provide a coherent curriculum that builds on what students learn in each grade, ensuring they acquire essential facts and concepts across various subjects. The Core Knowledge approach focuses on specific content areas, including literature, history, science, and the arts. By establishing a clear set of knowledge and skills, it helps educators create lesson plans that promote critical thinking and cultural literacy, preparing students for future academic success and informed citizenship.
