An IIT Madras professor has emphasised that engineering education must rest on four pillars—not only classroom instruction, to prepare students for emerging fields such as AI and robotics. The four vital components are teacher-led lectures, self-study, peer-to-peer learning, and experiential exposure. This model draws inspiration from an ancient verse in the Mahābhārata, suggesting that one-quarter of learning comes from teachers, one-quarter from self-effort, one-quarter from peers, and the final quarter through experience over time.
Four Pillars of Learning: Key Components
The professor outlined how each pillar contributes to a robust engineering education:
- Teacher-led Learning (Classroom Instruction): The foundation of engineering courses where core theories—mechanics, data structures, circuits—are communicated. It frames the essentials that students must understand before venturing further.
- Self-Study: Students must take initiative beyond lectures—reading additional material, exploring MOOCs, tutorials, or recent research to keep pace with rapid changes in technology.
- Peer Learning: Collaboration through technical clubs (robotics, programming, model building), group projects, and study peer groups fosters multiple ways of thinking. It enhances communication and soft skills as well.
- Experiential Exposure (Internships & Projects): Real-world exposure through labs, internships, and projects helps students apply classroom theory under real constraints, learning problem-solving, adaptability, and mentorship.
Relevance to AI, Robotics and Long-Term Career Growth
According to the professor, in sectors like AI and robotics, reliance on just classroom learning leaves students less prepared:
- These fields move fast; what is current theory now may become obsolete soon. Self-study and hands-on experience help bridge the gap.
- Peer networks and clubs allow students to experiment, fail fast, and innovate in ways not always possible in formal labs.
- Internships and real world challenges help translate abstract knowledge into relevant skills. Over time, this builds capability and resilience.
Strategy for Students
To make the most of this model, engineering students are encouraged to:
Neglecting any one pillar, the professor warns, can leave gaps in understanding or skill.
The Mahābhārata Connection: A Timeless Model
The educational verse cited from Mahābhārata frames this four-part learning in ancient wisdom: teacher, self, peer, experience. It underscores that integrated learning is not a modern invention but has roots in classical tradition, yet remains profoundly applicable today.
