DEVELOPING OF COMPUTERIZED NATURAL SCIENCE TEST

Abstract

This study is aimed at: (1) describing the caracteristics of Natural Science test developed, and (2) describing a computer program which had been developed to determine the test scores of students with modern test theory. Natural Science test consists of 600 items and had been tested in junior high school throughout Solo Raya with 1,800 respondents. Data analysis technique which was used is R programming. The computer program had been developed and tested in SMP Negeri 4 Polokarto (Polokarto 4 Junior High School). The results of the analysis of Natural Science program test with R programming show that: (1) item difficulty is in the range of -2.001-1.713, (2) discriminatory power of items is in the range of 0.553-2.394, and (3) the supposition of items is in the range of 0.000-0.379.
