Abstract
This study aims to find out reliability and estimating the standard error measurement of the questions which have been designed by the teacher. The data analysis was based on the response of 635 students towards the test instrument of Physics Final Exam of grade XII in six schools, which were located in Bima Regency. Test instrument reliability was analysed by using Iteman 4.3 software. Standard Error Measurement analysis of the six test instruments was done by using Compound Binomial Method, Anova Method and Iteman. Index of test instrument reliability in State Senior High School 1 and State Senior High School 3 is less than 0,7, while the test instrument in State Senior High School 2 Sape, MAN, Muhammadiyah Senior High School and PGRI Senior High School are more than 0,7. Standard error measurement extremely depends on the error, which is caused by the test instrument, in this case, the reliability of some tests. The result of this study shows the teachers' need for training in designing proper test questions.
Highlights
In carrying out the evaluation, measurement is a step that must be taken
This study discusses the estimation of reliability and the standard error measurement of UAS questions at the physics subject of grade XII in six schools in Bima District
The results of this research show that the test instrument used by State Senior High School 1 Sape and State Senior High School 3 Sape still do not meet reliability requirements
Summary
In carrying out the evaluation, measurement is a step that must be taken. When an evaluation process will be carried out, it should be preceded by a careful measurement process. Educational measurement is an activity to quantify symptoms or objects. Symptoms or objects can be in the form of motivation, achievement, confidence or achievement, all of which are expressed in the form of numbers [1]. The numbers obtained from the measurement results will help the researcher/teacher know the level of success of the learning process carried out. The information obtained through measurement is the result of the process of analysing data with certain techniques. The teacher conducts an intensive assessment to see the success of the learning process, whether the numbers obtained through measurements have met the standards of success or vice versa [2, 3]
