COMPARISON OF PSYCHOMETRIC PROPERTIES INTEGRATING INDICATORS OF READING ANALYTICAL THINKING AND WRITING ABILITIES AND INDICATORS OF CONTENT SCIENCE OF NINE GRADE USING THE DIFFERENT ITEM REVIEW METHODS
Abstract:
The purposes of this research was to compare psychometric properties integrating indicators of reading, analytical thinking and wiring abilities and indicators of content science of ninth grade using different item review methods. Participants of this research comprised of 750 ninth grade students. Data were collected using the test integrating indicators of reading, analytical thinking and writing abilities and indictors of content science of ninth grade. The items were classified into Item Form A for self-review of item and Item Form B for expert group review of item. In addition, data was collected using test for measurement of students in small-sized, medium-sized and large-sized schools. Content validity, reliability, item information, test information, difficulty and discrimination were employed to analyze the data. Research findings were as follows: 1) The result of content validity analysis on constructed questions and entirely passed review using determined check criteria described that all tests were congruent with assessment criteria in high level, indicating that all questions had content validity. 2) The result of reliability analysis using Cronbachs alpha coefficient for internal consistency revealed that in a small-sized school, the reliability of both Test Form A and Test Form B were in a low level. The Cronbachs alpha coefficient values of the Test Form A and Test Form B were not statistically significant different at .05. For a medium-sized school, the reliability of both Test Form A and Test Form B were in a high level. The Cronbachs alpha coefficient values of the Test Form A and Test Form B were not statistically significant different at .05. As for a large-sized school, the reliability of both Test Form A and Test Form B were in a low level. The Cronbachs alpha coefficient values of the Test Form A and Test Form B were not statistically significant different at .05. 3) The result of average item information function analysis for Test Form A and Test Form B indicated that average item information function values for both forms of tests in a small-sized school, a medium-sized school, and a large-sized school, entirely had no statistically significance at the level of .05. Moreover, the result of the average test information function value analysis for Test Form A and Test Form B indicated that the average test information function values for both forms of tests in a small-sized school and a medium-sized school were statistically significance level of .05, whereas the average test information function values for both forms of tests in a large-sized school were not statistically significant different at the level of .05. 4) The result of the tests analysis according to a classical test theory and an item response theory indicated that students scores who took the Test Form A and the Test Form B in the three different school sizes (i.e., small-sized, medium-sized, and large-sized schools) were not statistically significant different at the level of .05 in terms of difficulty and discrimination.
