Explanation : Teaching is a planned activity which seeks to
realise the instructional objectives set out at
the beginning using in the process some aids
and resources and some tests to evaluate the
learning. The level of accomplishment of the
objectives is a measure of effectiveness of
the teaching exercise and so is the usefulness
of the resources used by the teacher as well
time taken by students to learn.
Regularity of students is not related to
effectiveness of teaching. Marks obtained
by students may be a result of other factors.
