In good faith: To understand radians, one must revisit the wisdom of its founders
An opinion column published by The Indian Express argues that learning radians should start from the concept’s original meaning to improve conceptual clarity.

What happened
Background and earlier position
Many teaching approaches introduce radians using procedure-heavy explanations such as conversion between degrees and radians and formula-based calculations. Under a procedure-first approach, learners may treat radians as a rule for computation rather than a definition tied to circle geometry.
The opinion column contrasts meaning-based learning (understanding what a definition represents) with step-based procedural learning (following calculation steps to get results).
