Step 1: Concept
The relationship between externally imposed discipline and self-discipline, particularly in the context of student behavior.
Step 2: Meaning
Assertion (A): Imposing discipline on students may not yield the desired change in behaviour. Reason (R): Self discipline is the only effective discipline.
Step 3: Analysis
Externally imposed discipline involves rules and punishments enforced by external authorities. While it can control behavior in the short term, it may not lead to long-term behavioral changes because students might not internalize these rules. Self-discipline refers to an individual's ability to regulate their own behavior without external enforcement. It encourages personal accountability and intrinsic motivation, leading to more lasting positive behaviors. The assertion that external discipline alone is insufficient aligns with the reason that self-discipline (internalization of rules) leads to genuine behavioral change.
Step 4: Conclusion
Both assertion and reason are correct, and the reason correctly explains why imposing external discipline may not yield desired behavioral change.
Final Answer: (A)
