Erdem-Kara, Basak; Dogan, Nuri – International Journal of Assessment Tools in Education, 2022
Recently, adaptive test approaches have become a viable alternative to traditional fixed-item tests. The main advantage of adaptive tests is that they reach desired measurement precision with fewer items. However, fewer items mean that each item has a more significant effect on ability estimation and therefore those tests are open to more…

Kilic, Abdullah Faruk; Dogan, Nuri – International Journal of Assessment Tools in Education, 2021
Weighted least squares (WLS), weighted least squares mean-and-variance-adjusted (WLSMV), unweighted least squares mean-and-variance-adjusted (ULSMV), maximum likelihood (ML), robust maximum likelihood (MLR) and Bayesian estimation methods were compared in mixed item response type data via Monte Carlo simulation. The percentage of polytomous items,…

Uysal, Ibrahim; Dogan, Nuri – International Journal of Assessment Tools in Education, 2021
Scoring constructed-response items can be highly difficult, time-consuming, and costly in practice. Improvements in computer technology have enabled automated scoring of constructed-response items. However, the application of automated scoring without an investigation of test equating can lead to serious problems. The goal of this study was to…

Yalaki, Yalçin; Dogan, Nuri; Irez, Serhat; Dogan, Nihal; Çakmakçi, Gültekin; Kara, Basak Erdem – International Journal of Assessment Tools in Education, 2019
Developing scientific literacy for all students is the most often stated purpose of contemporary science education. Nature of science (NOS) is seen as an important component of scientific literacy. There are various perceptions of NOS in the science education community and NOS itself is an ever-changing construct. This makes it challenging to…

Inal, Ebru; Altintas, Kerim Hakan; Dogan, Nuri – International Journal of Assessment Tools in Education, 2018
The Health Belief Model (HBM) is one of the oldest and most recognized conceptual framework of health behavior and can be applied to disaster preparedness efforts which focus predominantly on human behavior. The study aims to develop and test the psychometric properties of the General Disaster Preparedness Belief (GDPB) scale based on the HBM. A…
