Classroom assessment and evaluation seeks to gauge the student’s performance through validated tests and other ways but does this really measure a student’s performance? Or more importantly, what the student has learned? Can knowledge be measured? Can intelligence be measured? What about multiple intelligence? Can that be measured?
Teachers create tests based on objectives they have stated in their lesson plan with the aim of inducing learning in students. They develop written exams [like multiple choice exams] by item analysis and norming to get a standard to which the student will be compared to. The test validity is checked and distractors are analyzed.
As good as the process seems, I believe this can only measure a student’s knowledge up to a certain point. It does not measure the entirety of the student’s knowledge. These tests assess only what is in the present, they don’t measure how a student will apply what he has learned later on in life. Sometimes these tests are only geared to logical-mathematical, and language-oriented students. What about the musical oriented students or the artistic-oriented students? How can their learning be measured and evaluated if the test does not appeal to their intelligence? Will a written test be appropriate to measure what they have learned? They might have learned in another way which is different with how the test wants to gauge it. That is why I believe that a student’s knowledge cannot be measured. A student’s knowledge is like a river [flowing through life]. Classroom assessment and evaluation is like a port in the river, it can see the effects of the river up to the area which encompasses the port. In other words, classroom assessment and evaluation only measure a certain point in a student’s knowledge development. It does not measure the knowledge which a student can acquire in his whole life.
I believe that knowledge cannot be measured but classroom assessment and evaluation seeks to at least measure it in the form of tests. These tests might not measure the entire scope of knowledge that a student has amassed and some tests are not geared correctly towards the student’s intelligences but a properly created test can provide a certain measure which is enough to satisfy scholastic standards.
