competence of the material taught by the teacher to
students is quantified by giving a test score. The
need to take measurements at school and in class is
necessary, in terms of measurement to find out
where students 'knowledge, students' ability limits,
student attitudes and interests. From the student's
point of view, the measurement must be precise,
whether it is through an exam or through other
measurement instruments. Where as from the
teacher's perspective, measurement gives feedback
about students. From the measurement results can be
known the obstacles faced by students and can be
used as a principle of assessment of student
achievement and provide feedback for teacher
teaching.
Most measurements of student achievement in
the classroom are carried out through examinations.
Because measurement is an integral part of teaching,
a teacher must be able to carry out the measurement
through the test he made.
The test is a measuring tool that is often used to
obtain empirical evidence for the purpose of
assessing teaching and learning in schools. Gullatt &
Ballard (2008), states that the main purpose of the
exam is to produce evidence that can be used to
make an assessment of teaching and learning in
school. Assessment in class can help teachers
improve their teaching and student learning. In
addition to information for teaching and learning
diagnosis, exam scores are also used as a basis for
the selection of majors, student placement, and
student coaching. Therefore, the right way to ensure
this is by holding a quality exam.
The quality improvement strategy for the teacher-
made summative test made in senior high schools in
South Sumatra. The analysis shows that: for the
quality of the summative final exam made by the
teacher multiple choice objective form, which was
assessed based on the percentage of valid items
which obtained 35 people (58%) the teacher was in
the simple and good stage, 9 people (15%) the
teacher was found has a valid percentage of items at
the good stage, 26 people (43%) teachers are in
sufficient stages, while 25 people (42%) teachers are
in the low stage.
Summative test reliability multiple choice
objective forms made by teachers generally are in
sufficient stage, namely as many as 28 people (47%)
teachers, 23 people (38%) teachers develop
examinations that have reliability at good stage,
while 9 people (15%) teachers are at the stage low
test reliability. The results also show that the
teacher's level of summative exam difficulty level is
generally low. There are 42 people (70%) teachers
who are in the low stage, while 18 people or 30% of
teachers are in the sufficient stage.
The results of the study also show that different
power indices (discrimination) for summative
examinations made by teachers generally have a low
stage. Most teachers, 57 people or 95% of teachers
are at a low level. The teacher in making a test with
a different level of power is one teacher, in enough
stages there are 2 teachers. The effectiveness of
distractor for teacher-made summative examinations
generally has a low stage. Most teachers, 44 people
or 73% of teachers have at a low stage. The teacher's
summative exam in making a test with a Deceiver at
the sufficient stage there are 12 people (20%)
teachers.
The relationship between summative
examination quality and teacher background such as
teacher's latest education, frequency of making
examinations, teacher teaching experience, and
training in evaluation in the last three years of
teaching turned out to be insignificant. Probably the
reason that the teacher is influenced also by other
factors such as affective background in the form of
attitudes, interests, talents, this motivation needs to
be considered. Other factors include socioeconomic
backgrounds such as family expenses, family
education and the number of family members. These
factors are believed to influence teachers in making
high-quality summative exams.
Developing a summative exam, the teacher states
that they consider all aspects as references in
developing good questions. The choice of aspects
that lack consideration in developing the test, is to
determine a different power index, namely there are
41 teachers, and develop an exam at the level of
difficulty, namely there are 26 teachers.
The obstacles faced by the teacher in developing
the summative test are determining the validity
(valid items) and reliability of the test there are 38
teachers, assessing the effectiveness of the distractor
there are 36 teachers, analyzing teacher-made tests
there are 34 teachers, in assessing the quality of
homemade tests there are 30 teachers. The obstacle
is also faced by the teacher in developing and
holding summative examinations in determining the
number of items with the exam time of 28 teachers,
determining the test lattice there are 26 teachers,
choosing the appropriate words on the exam
there are 25 teachers, determining the type of
exam that matches the purpose 23 the teacher,
compiling the exam questions there are 21 teachers,
determining the purpose of the exam there are 16
teachers.
