Concept:
Educational philosophy evolves through distinct historical periods: Ancient, Enlightenment, Modern (Progressive), and Post-Modern (Critical Pedagogy).
Step 1: Identifying the Historical Context.
• A. Socrates (Ancient Period): Known for the Socratic method in Ancient Greece (~400 BCE).
• B. Rousseau (18th Century): Author of *Emile*, representing the Naturalism movement (Enlightenment).
• C. John Dewey (Late 19th/Early 20th Century): The father of Progressive Education and "Learning by Doing".
• D. Maria Montessori (Early 20th Century): Developer of the Montessori method focused on self-directed activity.
• E. Paulo Freire (Mid-to-Late 20th Century): Known for *Pedagogy of the Oppressed* and Critical Pedagogy.
Step 2: Sequencing.
The sequence flows from Ancient $\rightarrow$ Enlightenment $\rightarrow$ Early Modern $\rightarrow$ Mid-20th Century. This aligns perfectly with the order A-B-C-D-E.
