A Comparison of Differential Scoring Methods For Multiple Choice Tests in Terms of Classical Test and Item Response Theories

Öz

The purpose of this research is to determine the effects of binary (1-0) scoring, judgement-based (a priori) option weighting and empirical option weighting on the reliability and validity of a multiple-choice test regarding Classical Test and Item Response theories. Data were collected through the administration of a multiplechoice test of verbal ability to 1593 students attending several departments at Hacettepe and Gazi Universities. Research findings showed that regarding Item Response Theory, “1-0“ scoring estimates the parameters within different intervals on the ability scale more precisely than weighted scoring and binary scoring is superior to weighted scoring in terms of validity. In case of Classical Test Theory, results indicated that empirical option weighting estimates the highest reliability and all scoring methods cause an identical effect on test validity.

Klasik Test ve Madde Tepki Kuramlarına Göre Çoktan Seçmeli Testlerde Farklı Puanlama Yöntemlerinin Karşılaştırılması

Öz

Bu fuar, çoktan seçmeli bir testte yer alan madde seçeneklerinin iki kategorili (1-0) puanlama, uzman yargılama hakkı seçeneği ağırlıklandırma ve deneysel seçenek ağırlıklandırma Klasik Test Kuramı ve Madde Tepki Kuramı'na göre nasıl etkilendiğinin olduğu amaçlanmıştır. Araştırma verisi çoktan seçmeli bir sözel yetenek testinin, Hacettepe ve Gazi Üniversitesi'nin farklı bölümleri okuyan toplam 1593 öğrenciye almayayla elde edilir. Araştırmanın bulguları, Madde Tepki Kuramı'nda “1-0” puanlamanın yapıldığı kapasitesi ölçeği rampa parametrelerin nüfus puanlamaların daha uygun kestirildiğini göstermiş, bu orantılı test geçerliği. Klasik Test Kuramı'nda ise deneysel daha fazla kestirilmiştir, bütün yöntemlerin test geçerliği ödeme benzer etkiyi belirlenmiştir.
