EXAM = MEASURING INSTRUMENT
Each examination is an educational measuring, regardless of the method. In order for the gathered results to be reliable and useful, a written exam (measuring instrument) should have the following qualities:
1) validity - precision degree of whether
the test really measures what we want to
measure,
2) relevance - degree of accordance between the questions
in the test and instructional goals,
3) reliability - repeatability/consistency with which
a test measures the selected variable, expressed through
standard measuring error (reliability coefficient),
4) objectivity - degree of accordance between competent experts
about the importance of the results, where each student's knowledge
is compared to a previously determined standard knowledge (one of
the standards is the so called minimum required score).
