Existentialism emphasizes individual experience and freedom of choice over external influences. It became popular after World War 2 as a philosophy of individuality. Key existentialist philosophers include Kierkegaard, Sartre, and Jaspers. An existentialist education focuses on giving students freedom to make their own choices and experience the consequences, helping them develop identity and responsibility. The curriculum prioritizes experiential learning over standardized content. Teachers facilitate choices and guide students through both successes and failures.
