Purpose: The primary objective of this research paper was to examine the objectivity of the preselected items evaluation (PIE) method, a prevalent translation scoring method deployed by international institutions such as UAntwerpen, UGent and the University of Granada. Design/methodology/approach: This research critically analyzed the scientific…

Insufficient effort responding (IER) refers to a lack of effort when answering survey or questionnaire items. Such items typically offer more than two ordered response categories, with Likert-type scales as the most prominent example. The underlying assumption is that the successive categories reflect increasing levels of the latent variable…

This study analyzes the consequences of item nonresponse to the question about a household's total net income in the European Social Survey (2008-2018). We recognize two mechanisms in avoiding answering the income question: task complexity and question sensitivity, and apply multilevel logistic regressions to predict the probability of refusals or…

In this study, it was aimed to examine the effect of missing data in different patterns and sizes on test equating methods under the NEAT design for different factors. For this purpose, as part of this study, factors such as sample size, average difficulty level difference between the test forms, difference between the ability distribution,…

Academic advising is one of the key practices in U.S. higher education institutions for supporting students' success. However, the complexity of academic advising program structures, the difficulties in identifying appropriate outcome measures, and the lack of inclusion of multiple stakeholders' perspectives continue to challenge scholars to…

Background: Globally, conducting randomised controlled trials can be a complex endeavour. The complexity increases when including participants with cognitive or intellectual disabilities. A fuller understanding of the barriers and challenges that can be expected in such trials may help researchers to make their trials more inclusive for people…

Morphological awareness has been assessed longitudinally for monolinguals and bilinguals to trace the developmental trend. Researchers have found the important role it plays in literacy development including vocabulary growth and reading development. Conclusions about the important role morphological awareness play in literacy development are…

I found the need to explore the difficulties faced by Arabic-speaking English language learners studying mathematics as soon as I moved to the United Arab Emirates. Thus, I began a line of research that aimed to explain and understand these issues and find effective teaching strategies for the students. This case study describes the first research…

Van Gog and Sweller (2015) claim that there is no testing effect--no benefit of practicing retrieval--for complex materials. We show that this claim is incorrect on several grounds. First, Van Gog and Sweller's idea of "element interactivity" is not defined in a quantitative, measurable way. As a consequence, the idea is applied…

Educational research teams are increasingly recognized as an optimal configuration for addressing more complex mixed methods research problems; however, their development is often approached as a conventional research collaboration rather than an integrative one. An approach informed by complexity theory provides the practical guidance for…

This study aims to investigate the effect of methods to deal with missing data on item difficulty estimations under different test length conditions and sampling sizes. In this line, a data set including 10, 20 and 40 items with 100 and 5000 sampling size was prepared. Deletion process was applied at the rates of 5%, 10% and 20% under conditions…

This paper investigates the relationship between blank and non-blank email subject lines on levels of response to a solicitation to participate in an interview, and on participation in a web survey. Email use has grown substantially in recent years, presenting significant opportunity to the empiricist seeking research respondents. However,…

In this article, I provide a conceptually oriented overview of Bayesian approaches to statistical inference and contrast them with frequentist approaches that currently dominate conventional practice in educational research. The features and advantages of Bayesian approaches are illustrated with examples spanning several statistical modeling…

The performance of information retrieval systems varies significantly by test topics. Even for those systems that have performed well on average, the results for some difficult topics are still poor. Previous studies have revealed that different optimization techniques should be used for those difficult topics. However, a prerequisite of the…

There has been criticism about STEM education not focusing enough on problem solving, especially in authentic real-world contexts which are most often associated to ill-structured domains. To improve education, it is essential that curricula bring students to high levels of cognitive development by exposing them to authentic problems.…
