Angoff, Nedelsky ve Ebel Standart Belirleme Yöntemleri ile Belirlenen Kesme Puanlarinin Karşılaştırılması

Abstract

In this study, it was aimed to compare the cutting points determined by Angoff, Nedelsky and Ebel methods. Data were collected from two different groups comprising of students and experts. The mathematics achievement test, comprising of 26 questions which was developed by the researcher with the aim of evaluating the objectives of 9th grade mathematics course, was applied to 245 students and obtained achievement scores were used as student data of the study. Expert data of the study were collected by the “Expert Opinion Form developed by the researcher.The differences between the percentages of students, considered as successful, have been tested with the test of difference between two percentages. The compliance between three methods has been examined with Cohen’s Kappa statistics. The relationship between the MGP has been evaluated with Pearson-Product Moment Correlation Coefficient and the difference between the averages of the cut-off scores has been evaluated with paired samples t-test. At the end of this research, it is seen that the highest cut-off score is determined by Angoff while the lowest cut-off score is determined by the Nedelsky and also the percentages of students differ statistically significant. When the students are classified as successful and unsuccessful it is seen that there is a high positive compliance between Angoff and Ebel, and Ebel and Nedelsky while there is a positive compliance between Angoff and Nedelsky. In terms of the MGP, there is compliance between Angoff and Ebel, but there is no compliance between Angoff and Nedelsky.
