Essentialism is a philosophy that values the inherent essence or attributes that define what makes an entity fundamentally what it is. It postulates that objects in the real world are mere representations of abstract ideal forms. As an educational philosophy, essentialism believes students should learn traditional basic subjects thoroughly by installing them with the "essentials" of academic knowledge through a teacher-centered approach where the teacher interprets the essential learning process and sets the tone in the classroom. Criticisms of essentialism include that it allows for little student freedom or creativity, though it does provide a strong foundation of basic knowledge and skills.
