Explanation : By advocacy is meant 'support, encouragement
and recommendation' for the client-who,
in case of classroom communication, is the
teacher's student. The teacher's advocacy is
a key element in classroom communication
as it motivates students to learn and excel.
On the other hand, the teacher's passivity
demotivates learners; negativity impairs
academic achievement and harms their
psychological as well as physical health;
and deflection from the topic underway
compromises the learning outcomes. All of
these hamper communication.
