Essentialism is a philosophical concept that emphasizes the idea that certain entities have a set of attributes that are necessary to their identity. This means that each thing, whether it be a person, object, or idea, has an essence that defines what it is. For example, the essence of a tree includes characteristics like having a trunk, branches, and leaves, which distinguish it from other living things. In education, essentialism advocates for a curriculum focused on core knowledge and skills that are deemed essential for students. This approach prioritizes foundational subjects such as math, science, and literature, aiming to equip learners with the critical tools they need for success in life.
