The
Concept of Measurement & Evaluation
Measurement is the process by
which we ascertain the quantity of something. It is merely the assignment of
a numerical index to the thing or phenomenon we measure.
Evaluation is the process by
which we judge the quantity of aomething . It is the process of determining the
extent to which an objective is achieved or the thing evaluated possess the qualities
envisaged.
The term measurement
and evaluation are quite often used as
synonym . It is true that these two terms have something
in common . At the same time they differ in certain respects.
Measurement
is a precondition for evaluation .
Measurement is quantitative while
evaluation is qualitative also.
Evaluation is a
process of assigning value to something . This is possible only on the basis of specific pre-determined goals. Therefore evaluation in education warrants the
determination of specific educational goals. From the point of view of the
class room teacher instructional objectives act as the basis of evaluation
.This means that educational evaluation is possible only if the instructional
objectives are determiner earlier . Evaluation based on pre-determined
objectives is called objective based evaluation .
