Constructing a Criterion-Referenced Test for Educational Research Skills in Line with RASH Model with Postgraduates in Education Faculties in Yemeni Universities

Abstract

This study aimed to construct a criterion-referenced test for educational research skills in line with RASH model with postgraduates in faculties of education in Yemeni universities. To achieve the objective of the study, analytical-descriptive and evaluative approaches were used. A purposive sample of 125 male and female postgraduates was selected to be administered a multiple-choice test to measure educational research skills. The test was composed of 90 items, designed accurately,  distributed over five basic skills. The data were then analyzed using the SPSS program (Xcalibre 4.2.2.0, 2014), using various classical and modern statistical techniques. Accordingly, a number of findings were revealed, most notably: applying  responses to 88 test items based on the model's assumptions, deleting two items that did not match the model, and deleting 4 participants who did not match the model; the items of difficulty parameter estimates were acceptable within the scientifically acceptable range; the test showed multiple manifestations of validity and reliability (0.92, 0.94) with the participants' abilities; the value of the information function was maximum approximately (b =⁡θ) as expected from RASH Model; and the test showed the greatest amount of information at an average level, and the least one at high and low levels.
