Which one of the following is not included in classroom communication?

Correct answer: A) Indirect communication. Classroom communication is usually classified along two axes: formal or informal, depending on whether it follows the prescribed curriculum and institutional structure, and verbal or non-verbal. Silent communication is a recognised non-verbal mode, where a teacher conveys meaning through gesture, facial expression, pauses or silence itself.

• Formal communication covers lesson delivery, instructions and assessment that run through the official curriculum and timetable. It is included.
• Informal communication covers casual exchanges, peer talk and conversation outside the syllabus. It is included.
• Silent communication is non-verbal and is included.
• Indirect communication is not a standard category in classroom communication literature, so it is the odd one out here.

Core concept: teacher-education texts used in B.Ed. and NCERT-based pedagogy treat formal and informal as the main divide. For Mains, this connects to teacher effectiveness and classroom practice in education policy answers under GS-IV.

Trap: candidates overthink 'silent' and 'indirect' as both being non-verbal and pick the wrong one. Stick to the standard categories in teacher-education texts.
