The heuristic method is a teaching method that involves allowing students to discover things for themselves through exploration and problem solving rather than direct instruction. It places students in the role of discoverers. Key principles include freedom for students, an environment that is responsive to their needs, and guidance from teachers as needed. The method aims to develop skills like critical thinking, logical reasoning, and scientific inquiry in students. Teachers play an important guiding role by selecting suitable problems, asking questions, and helping students arrive at conclusions while allowing freedom. While time consuming, the heuristic method can develop self-learning, scientific temperament, and retention of knowledge in students.
