Determination of cutting score in performance tasksPerformans görevlerinde kesme puanının belirlenmesi

Performance tasks are important in terms of meaningful learning since they enable students to use the information they have learned in their daily lives. Performance task is also the most commonly used method that our teachers use apart from written exams. While evaluating performance tasks, it is necessary to determine whether the tasks that students have prepared are adequate or not. In order to determine the measure of this decision, standard-setting studies have been carried out. In this study, passing score of a prepared performance task was determined through one of the standard-setting methods, Angoff method. 26 mathematics teachers who are working in various high schools in different cities participated in the study as experts. Data collection tool is a five-question performance project that is called ‘As the Crow Flies’ and includes coordinate plane and Pythagoras theorem. In the process of data collection, each expert was shown the questions in the performance task, and asked about the possibility of giving correct answers for the students who were on the border of failing. The consistency of points among experts were determined through Kendall’s W coefficient of concordance ( =137.872, sd=9, p
