VALIDITY
Hi all.. Today we
meet again.. On this week (week 5) in the classroom learning assessment, I
have learned
something about the validity.
v According by Theory
Campbell (1959: 83),
Validity is
agreement between different measures of the same trait (correlation between
scores on a multiple choice test of grammar and ratings of grammar on an oral
interview).
Validation
is the process of establishing the validity of a test, which is one of the basic
concerns of language testing.
Furthermore, we
also had learned about the type of validity.
v TYPES OF VALIDITY
Divided into
five types :
-
Face validity – to
measure the knowledge or abilities it claims to measure, as judged by
an untrained observer.
-
Content validity -
Describes how well the content of the test samples the subject matter.
-
Predictive validity -
Degree to which predictions made from the test are confirmed by
evidence gathered at some later time.
-
Concurrent validity -
Concerned with the relationship between what is measured by a test
and another existing criterion measure.
-
Construct validity - An
indication of how representative a test is of an underlying theory
of language learning.
At the end of
discussion, we have made examples of each type of validity to demonstrate our
understanding of what is taught by the lecturer. These activities are conducted
in groups and also showed a challenge to members of the group about the
importance of cooperation within the group.
