Journal Title: Journal of Human Sciences - Year 2018, Vol 15, Issue 2
Abstract
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<0.00). According to the points acquired from experts, it was concluded that although there was not a high level of consistency among experts, there was a moderate level of consistency. As a result of the calculations, final cutoff score was found to be 45.10. Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetPerformans görevleri, öğrencilerin kavradıkları bilgileri günlük hayatla bağdaştırmaları ve anlamlı öğrenmeler açısından önemlidir. Ayrıca öğretmenlerin yazılı sınavlar dışında en çok kullandıkları yöntemlerden biridir. Performans görevlerini değerlendirirken öğrencilerin ortaya koydukları performans görevlerinde yeterli olup olmadıkları hakkında karar verilmesi gerekmektedir. Bu kararın hangi ölçüte göre verileceğini belirlemek için standart belirleme çalışmaları yapılmaktadır. Bu araştırmada, hazırlanan bir performans görevine ilişkin geçme puanı, standart belirleme yöntemlerinden biri olan Angoff yöntemi ile belirlenmiştir. Çalışmaya farklı illerdeki liselerde çalışan 26 matematik öğretmeni uzman olarak katılmıştır. Veri toplama aracı ‘Kuş Uçuşu’ olarak adlandırılan, koordinat düzlemi ve Pisagor teoremini içerenbeş soruluk bir performans görevi kullanılmıştır. Veri toplama sürecinde her bir uzmana performans görevindeki sorular gösterilerek, bu soruları geçme-kalma sınırındaki bir öğrencinin doğru cevaplama olasılığı sorulmuştur. Puanlamada uzmanlar arası uyumun olup olmadığı Kendall’ın W uyum katsayısı ile belirlenmiştir ( =137.872, sd=9, p<0.00). Elde edilen sonuca göre, uzmanlar arasında orta düzeyde anlamlı bir uyum olduğu sonucuna varılmıştır. Yapılan hesaplamalar ile nihai kesme puanı45.10 olarak bulunmuştur.
