A Construction of a Test to Measure English Reading Comprehension Skills for Grade 6 Students by Applying Generalizability Theory

Abstract

The objectives of this study are (1) to construct a test to measure English reading comprehension skills for grade 6 students and (2) to compare the generalizability coefficient of the English reading comprehension test for grade 6 students under the different items (p x i) by applying generalizability theory. The samples consisted of 243 grade 6 students. The research instrument was an English reading comprehension test, a multiple-choice test in which there were 5 items, and each item consisted of a situation. In each situation, there were a total of 3 sub-questions, totaling 15 sub-questions for measuring English reading skills at 3 levels: literal reading, interpretative reading and critical reading. Data analysis consisted of a score analysis from a test using fundamental statistics and the analysis of the G-coefficient of the test based on the generalizability theory. The EduG program was employed. The findings are as follows: (1) The test had content validity. It had a reliability of 0.79. The item difficulty value was in the range of 0.25 - 0.67 and the item discrimination value was in the range of 0.22 - 0.73. (2) The result of comparing the generalizability coefficient of the test under the different items: 1, 3, 5, 7 and 9 items with reliability of 0.7 or above, there were 5, 7 and 9 appropriate items.
