Difference between Measurement and Evaluation
The main difference between evaluation and measurement may be explained with the help of following examples.
- A teacher measures Mr. Aslam's height to be 180cm He evaluates-his height when he says that he is long.
- A teacher measures Mr. Ali's achievement in Economics to be 50% he evaluates his achievement when he says that Ali's achievement in 'Economics is satisfactory
- A teacher measures the size of a classroom and finds that it is 4mx3m. He evaluates the classroom dimensions when he reports that the classroom is too small for 40 students.
- Aslam and Ali study in the same class, hi the first test they obtain in 50 and 70 marks respectively in English in the second test. Both of them obtain 80 marks. Now in the second measurement (test scores) achievement in English is the same yet the evaluation will differ when the teacher states that the rate of progress of Aslam is comparatively better than that of all.
Measurement helps in evaluation. This may be clarified, by taking one example. Aslam and Ali study in the same class. They take two tests. In the first test, they obtain 45 and 65 marks respectively in civics in the second test, both of them obtain 80 marks. Now in the second test the measurement (best scores) of their achievement in Civics is the same, yet the evaluation well differ, when teacher says that the rate of progress of Aslam is comparatively better than that of Ali.
