Çoklu Gösterimlerin Kullanıldığı Matematik Problemlerine Ait Çözümlerin Puanlayıcı Güvenirliği Açısından İncelenmesi

Abstract

The main purpose of this study is to examine the inter-rater reliability of the math problems, presented with four different representations (graphs, tables, equations, and verbal) on the basis of multiple representations in mathematics education. For this purpose, the generalizability theory is used in the scoring of the problem solutions and it is aimed to compare the G and Phi coefficients obtained in cases where crossed design is used.The open-ended mathematics problems are used in the research and students' solutions are graded by using a rubric. 54 students in the eighth grade of a public school participated in the study by solving the problems, and five mathematics teachers participated as a rater of students' solutions. As a result of the research, it was found that the problems in all representation types were effective on the inter-rater reliability, while the biggest difference was in the graphic representation.
