Explanation : Pedagogy and social interaction are indeed
two major result-oriented activities of
a teacher. Pedagogy, or the method and
practice of teaching gets results. If the
teacher takes into account the various
factors involved such as the availability
of resources, leamer's characteristics, individual differences, etc.; and plans
the instruction accordingly with the most
suitable methods, aids, and resources
possible to ensure equality of opportunity
to every learner, teaching is effective.
Teaching is also effective when the teacher
interacts and communicates well not only
with the learners but also the other members
of the teaching staff, school management!
administration and parents. Hence, (A) is true.
Communication is the vehicle that carries
pedagogy and social interaction forward.
So, it plays not a limited role, but a big role
in both these activities. Hence, (R) is false.
