Abstract:
The purposes of this research were to create a mathematics item model, to develop an Automatic Item Generation program for Grade 9 mathematics, and to study the relation between the test results obtained from the prototype test and those collected from the Automatic Item Generation program. The research was divided into three phases as follows: 1) Modeling Grade 9 mathematics items. 2) Developing an Automatic Item Generation program for Grade 9 mathematics. 3) Finding the relation between the test results obtained from the prototype test and from the Automatic Item Generation program by using the Grade 9 O-NET Mathematics exam from the academic year 2012-2018. The sample involved 105 Grade 9 students who studied in the second semester of the academic year 2019 at the Aranyaprathet school, Sakaew Province, under the Office of Secondary Educational Service Area 7. Data were analyzed with Pearson correlation. The results were as follows: 1. Fifty items modeling the math exam prototype consisted of five core courses: the 1 st learning area consisted of 16 items of number and operation, the 2 nd learning area consisted of 10 items of measurement, the 3 nd learning area consisted of 10 items of Geometry, the 4 th learning area consisted of 10 items of algebra, and the 5 th learning area consisted of 5 items of data analysis and probability. 2. The Developed Automatic Item Generation program of Grade 9 mathematics was developed for use on a website (www. aigmath.com). It was judged highly suitable by experts, and regarded to be at the highest level by teachers. 3. The items generated by the developed computer program were found to correlate positively with the prototype test, r= .92, significant at .01 level
