I
made a progress! I didn’t come late this time, and I hope that I can keep going
like this to other classes. So did my friends. The number of my friends that
came on time increased, and it so much better than before. This was my 3rd
meeting of language assessment class.
As
usual, before we learn new lesson, we reviewed what has been taught last week:
validity. Hence, we have deeper insight related to it. We analyzed some test
items by contemplating the construct validity of the items, so we knew what
knowledge and ability which is going to be tested by the items. Other than
that, we were be told several terms regarding assessment like test task, test item, lesson plan, and test taker.
After
that, we went on to the new lesson which called reliability and washback.
Term one, reliability, it refers to
consistency. What kind of consistency? The test. Thus, the result of the test
is consistent, hence it can be said that the test is reliable. Reliability of test
can be caused by several factor, such as student-related
reliability, it came from the condition of the student itself who became a
test taker. How is health condition of the student when the test is held? Is he
in trouble or not? However, it also can be effected not only by the student,
but also by the examiner. Does the examiner teach lesson which is tested? Does
he oversee the student when the exam is held? It is called scorer-related reliability. It is also influenced by all the things
related to the time when the test is held e.g. conducive situation and clear test
item paper. Anyway, this is what frequently happens during examination: unclear
test item. Such things called test
administration reliability. The test is reliable depends on the test itself,
it is known as test reliability. In
brief, reliability is essentially a
test that you can trust, and to know it is trusted is by observing those
aspects, namely: student, examiner, administration, and the test.
Term
two, washback also known as backwash and consequential validity. Washback
is a test effect. The test gives influence to the way students are taught. For
example: In Indonesia, there is a final exam namely national examination that
determines whether a student pass or not. There will be several weeks specially
to prepare student in facing the national examination. Those weeks will not be used
for teaching and learning activity, but for discussing hundred of test items
regarding to the course which will be tested. The national examination
certainly effects the way students are taught, therefore, basically, it
influences teaching and learning activity. Washback
is very important since it has essential effect to the learning activity.
Therefore, a test must be qualified, thus leads to qualified teaching and
learning activity.
Time
has shown at 09.30, class must be over. We got new knowledge which called reliability and washback which sharpen our insight about assessment, and I was
hungry, anyway! I did come on time, but I sacrificed my breakfast.
