Concept:
Modern educational psychology emphasizes understanding the causes of behaviour before taking corrective action.
Step 1: Understand student behaviour.
Violent or disruptive behaviour often results from emotional stress, frustration, peer pressure, family problems, or academic difficulties.
Step 2: Role of the teacher.
A teacher should first attempt to understand the underlying cause rather than reacting immediately with punishment.
Step 3: Evaluate the options.
Reporting to the headmaster may become necessary later.
Calling parents can be considered after understanding the situation.
Mobilizing teachers against students is inappropriate.
Identifying the reason addresses the root cause of the problem.
Step 4: Conclusion.
Therefore, the best response is to identify the reason behind the behaviour.
