Matching the student’s ability and their math test using Rasch analysis

Abstract

Individuals who have high abilities than other individuals should have a better chance of accurately performing the exam questions. On the other hand, the quality of the exams provided should be adhering to what the students received during the classroom. This study tried to assess the level of accuracy of students ability in math exams on geometry and fractional subjects. The study covered 20 elementary school students in Southeast Sulawesi. Data were tested using Rasch Model. The results of this study indicated that the overall students ability is below average (-.10 logit) and is slighter in order with the given mathematical test. More pointedly, students meet it problematic to work out the image in fractions and determine the circumference of the building area. Instead, students are comfortable to write down the fractional symbols, and arrange the images that have the smallest to the largest angle size. Furthermore, investigations of potential student scandalous action during the exam and the disparities in abilities between male and female students are also interesting points discussed in this article. This finding suggests that classroom teachers review math learning in the classroom as well as the quality of exam questions applied to students.
