Educational Measurement and Evaluation


                   Notes              1.   Oral Tests : Those tests in which the questions from the examinees are asked orally and
                                           the examinees have to answer orally are called oral tests. Such tests are generally
                                           comprised of short-answer and objective-type questions.
                                           The aim of teaching a subject is not limited to impart knowledge of the related facts,
                                           it is also taught to bring about a change in the thinking and working style of the
                                           students. And its measurement is done by oral tests. These tests are used for ascertaining
                                           their knowledge and practical use of linguistic abilities (pronunciation, lecture,
                                           expression style), their confidence and their knowledge of other subjects. The chief
                                           characteristic of these tests is that the examiner and the examinee are face-to-face with
                                           each other, so the examiner gets an opportunity to know the personal qualities of the
                                           examinees.

                                           These tests are subject to some shortcomings as well. First, the examiner can test only
                                           one student at one time which requires much energy and time. Second, these tests are
                                           subjective in nature and marking depends upon the examiner to a great extent. Third,
                                           change of behaviour as a whole, as a result of teaching of various subjects cannot be
                                           measured correctly. Fourth, the practical aspects of art and science subjects cannot be
                                           measured by these tests. Fifth and the last, these tests greatly depend on the ability and
                                           honesty of the examiners.
                                           It is evident that these tests should be made use of for measurement of students’
                                           pronunciation skill, linguistic ability, fearlessness, confidence and general knowledge
                                           of various subjects and their practice in life. But these tests can be beneficial  only if they
                                           are executed honestly. Moreover, these tests should be used only in those subjects where
                                           it is necessary.
                                      2.   Written Tests : The tests in which the examinees are given questions in written form and
                                           which they respond in writing, are called written tests. In these tests any types of questions
                                           can be asked as essay-type, short-answer-type and objective-type. So it is necessary to
                                           discuss them independently which we have done in the succeeding paragraphs.
                                      3.   Practical Tests : The tests in which the measurement of skills and activities of the students
                                           is executed by asking them to  display the skill or activity are called practical tests; such
                                           as asking a child to sing a song in order to measure his proficiency in singing.  Practical
                                           tests are used for the measurement of practical skills and knowledge in art, music,
                                           science and other practical subjects.
                                           The chief characteristic of practical tests is that the practical aspect of the examinees is
                                           measured. These tests alone can test the practical knowledge of arts and science. If a
                                           doctor or engineer is not tested as such, a flaw in his theoretical knowledge may create
                                           havoc.
                                           But these tests have their own limitations. First, we cannot correctly measure the
                                           theoretical knowledge and emotional aspect of a person by these tests. Second, their
                                           execution needs comparatively more energy and time. Moreover, these too have been
                                           embraced in the ambit of immorality.
                                           However, the practical skills can be tested only by practical tests. The need is of course to
                                           improve these tests. There is only one advice worth giving—the examiners should work
                                           honestly.
                                  (III) Classification on the Basis of Material Used

                                      The tests are classified into two types on the basis of material used in them, which are :
                                      1.   Verbal Tests : This type of tests includes those tests in which words or language are used
                                           which may be written or oral. Such tests are mostly used in the field of education.
                                      2.   Non-Verbal Tests : This type of tests includes those tests in which words or language are
                                           not used, rather scenery, symbols, signs, pictures, etc are made use of these tests are used
