ITEM ANALYSIS
- INTRODUCTION
Testing has an important role in teaching learning process. It
is used as an instrument for measuring and evaluating activities. Brown (2004:
03) states that a test is needed to measure the student’s abilities or performance
which focuses on specific competencies or objectives. Furthermore, a teacher
must have a good or qualified test for the students to get correct information
about student’s abilities. A qualified test means that a test must fulfill some
criteria of a good test.
In this paper I would like to analyze the final English test
items for the ninth year students of SMPN 1 NGORO MOJOKERTO 2008. The format of
the test is multiple choices which consist of 20 items number. The analyses are
about some criteria of good test. They are validity of the test (face, content,
construct), reliability of the test, item analysis and also the revision.
- VALIDITY
Validity refers to whether a test measures what we intend it to
measures (tucker, 1975:229). It means that validity of a test measure that it
is supposed to measure. If a test is able to measure what it its purposes, then
the test has high validity. In this case I’ll discuss the validity of a test
into three types; face validity, content validity, and construct validity.
1. Face Validity
Face validity of a test is that the way of a test is done by
looking at the way of the test is written, whether the test is constructed
based on the step of how to construct a good or not. Harris (1969:20) stated
that face validity can never be permitted is the way the test looks’.
Based
on Haris opinion above, the researcher concludes that the face validity of a
test refers to:
- The way the test ‘looks’ based on the tastes, the test administrator, and the educators’ point of views.
- The way the test is organized. It consists of test and test directions.
After identifying all of the test items, the writer makes an
analysis the validity of the English summative test items for the ninth year
students of SMPN 1 NGORO MOJOKERTO 2008. The test look is enough, because the
test has no cover and it has specific object clearly such as class, subject
lesson, time. The size is of letter is 12, good and can be read easily. The
test direction is enough because it has general instruction and it still there
are many instructions which is not clears enough. A test item type is multiple choices.
It consists of 20 item test. They are presented following the level of
difficulty.

2. Content Validity
As we know that the analysis of content validity of a test is
mean to find out the relationship of the test items with the content of
materials based on the curriculum being used. The most important question here
is whether the test item is measuring what should be measured. Heaton (1975:154)
states that content validity is extended to which a test measure a
representative sample of the subject-matter content. A test can be said to have
high content validity if the test items represent almost all of the content of
materials stated in the subject matter.

Based
on the analysis above, the percentage of content validity is concluded as
follows:
1.
There is no item for listening and speaking skill since the test
is given in the written form (0%).
2.
There are fourteen items for reading skill. It is number 2, 4, 6,
8, 10, 12, 14, 22, 24, 26, 28, 34, 36, 40. (70%)
3.
There are three items for vocabulary usage. They are number 16,
18, 20 (15%).
4.
There are three items for Grammar. They are number 30, 38 (10%).
5.
There is one general knowledge. Its number 32 (5%).
3. Construct Validity
Beside
considering the content validity. A good test must have construct validity.
According to Heaton (1975:154) if a test has construct validity, it is capable
of measuring certain specific characteristics in accordance with a theory of
language behavior and learning. This type of validity assumes the existence of
certain learning theories or constructs underlying the acquisition of abilities
and skills.

- RELIABILITY
Beside we learn the important the importance of validity. We
have to know the other a necessary characteristic any a good test. It is
reliability. Reliable means that the result of the test can be trusted or can
be relied. Reliability of the test is the stability of the test scores (Haris,
1969:14).
Tuckman (1975:157) states that the reliability of the whole test
can be estimated by using the whole KR-21 formula.
KR-21 formula:

Note:

D. ITEM ANALYSIS
Item analysis refers to the process of collecting, summarizing,
and using information about individual test item, especially information about
student’s responses to items. Brown (1996:50) states” item analysis is
performed simply to investigate how well the items or a test are working with a
particular group of students.
According to (Heaton, 1975:196) “an item analysis is done in
order to identify the best items. It means that the teacher have to know
whether the item are good or not in order to get the better result.
1. Item of Difficulty
Item
difficulty is also called facility value (the index og difficulty). Facility
value (F.V) is generally expressed as the fraction of the students who answered
correctly. It is calculated by using the formula:
F.V = Correct U +
Correct L
2n
Where:
F.V = the
facility value or the index of difficulty
Correct U = the number of the students in Upper group who answered the item
correctly.
Correct L = the number of the students in lower group who answered the item
correctly.
2. Item Discrimination
According to
Heaton (1975:179) “the discrimination index of an item indicates the extent to
which the item discriminates between the tastes, separating the more able from
the less able”. The index of discrimination (D) tells us whether those students
who performed well on the whole test tended to do well or badly on each items
in the test. It is calculated by using the formula:
F.V = Correct U - Correct
L
n
Where:
F.V = the
facility value or the index of difficulty
Correct U = the number of the students in Upper group who answered the item
correctly.
Correct L = the number of the students in lower group who answered the item
correctly
.

NOTES:
F.V
The
standard value of the index of difficulty is:
0.00-0.30 = difficult
0.30-0.70 =
good (average)
0.70-1.00. =
easy (Arikunto, 90: 212).
According to
Arikunto (1990: 221), the
criteria of the index
of discrimination are as follows:
D.P
E :
Excellent (0, 7 – 1, 00)
G : Good (0, 4 – 0, 7)
S : Satisfactory (0, 2 – 0, 4)
P : Poor (0, 0 – 0, 2)
VP : Very Poor (Negative)
3. The effectiveness of Distracter
"Distracter efficiency is one more important measure of
multiple-choice items value in test and, one that is related to the item
discrimination" (Brown, 2004; 60). It is really important to know the item
is good, not good or non function. From the table below, it can be seen that
the test is good when the correct answer in upper group is higher than the
lower group. Vise versa, when the uncorrected answer in lower group is higher
than the upper group. The analysis the test item can be said not good if the
correct answer in upper group is lower than the lower group and also the
uncorrected answer in lower group is lower than the upper group. The last, non
function means if the result of upper and lower group are the same.

This question is clear; most students can answer the question correctly.
The correct answer between upper and lower group is the same. But from the
content it is not include the curriculum
