The estimation of standard error measurement of physics final examination at senior high schools in bima regency indonesia

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.
