While delivering lecture if there is some disturbance in the class, then a teacher should

Keep quiet for a while and then go on
Not bother of what is happening in the class
Punish those causing disturbance
All of these

The correct answer is: A. Keep quiet for a while and then go on.

The teacher should first try to identify the source of the disturbance and address it calmly. If the disturbance continues, the teacher may need to take further action, such as asking the student to leave the classroom. However, it is important to remember that the goal is to maintain order in the classroom and continue with the lesson. Punishing students who are causing a disturbance may not be the best way to achieve this goal.

Here is a brief explanation of each option:

  • Option A: Keep quiet for a while and then go on. This is the best option because it allows the teacher to assess the situation and decide how to best handle it. If the disturbance is minor, the teacher may be able to ignore it and continue with the lesson. However, if the disturbance is more serious, the teacher may need to take further action.
  • Option B: Not bother of what is happening in the class. This is not a good option because it allows the disturbance to continue. If the teacher does not address the disturbance, it will only get worse.
  • Option C: Punish those causing disturbance. This is not always the best option because it can lead to resentment and further disruption in the classroom. It is important to remember that the goal is to maintain order in the classroom and continue with the lesson. Punishing students may not be the best way to achieve this goal.
  • Option D: All of these. This is not a good option because it is not always necessary to punish students who are causing a disturbance. In some cases, the teacher may be able to resolve the situation by simply talking to the students.
