Covariates have been used in mixture IRT models to help explain why examinees are classed into different latent classes. Previous research has considered manifest variables as covariates in a mixture Rasch analysis for prediction of group membership. Latent covariates, however, are more likely to have higher correlations with the latent class…

This research investigated the relation between racial categorization and implicit racial bias in majority and minority children. Chinese and Indian 3- to 7-year-olds from Singapore (N = 158) categorized Chinese and Indian faces by race and had their implicit and explicit racial biases measured. Majority Chinese children, but not minority Indian…

The notion of "linguistic minority" not only incorporates the concept of group but also serves to define that group. Yet the relation between language and group can be considered in various ways. The primary function of language being that of communication, this will necessarily play a key role in defining the contours of any group whose…

In peer observation of teaching, an experienced colleague in the educational environment of a faculty member observes the educational performance of that faculty member and provides appropriate feedback. The use of peer review as an alternative source of evidence of teaching effectiveness is increasing. However, no research has been done in the…

Research involving digital games and language learning is rapidly growing. One advantage of using digital games to support language learning is the ability to collect data on students learning in real time. In this study, we use educational data mining methods to explore the relationship between in-game data and elementary students' Chinese…

We examined the relation of morphological awareness with language and literacy skills, namely phonological awareness, orthographic awareness, vocabulary, word reading, spelling, text reading fluency, and reading comprehension. We also examined potential moderators of the relations (grade level, orthographic depth of language, receptive vs.…

This study, it was aimed to determine the predisposition levels of teachers and pre-service teachers to ethical values. The sample of the study consisted of 1305 educators, 784 teachers, and 521 pre-service teachers in 15 different branches in the 2021-2022 academic year. The sample of the research conducted in the relational survey model was…

Experimental inquiry-oriented science labs can be designed to have students regulate their own learning and decide when they leave class or to have the teacher regulate student learning and determine when they leave class. In this study, grades were examined relative to student exit times in a student-regulated class design. Preliminary interviews…

In secure web application development, the role of web services will not continue if it is not trustworthy. Retaining customers with applications is one of the major challenges if the services are not reliable and trustworthy. This article proposes a trust evaluation and decision model where the authors have defined indirect attribute, trust,…

A STEM (science, technology, engineering and mathematics) analysis project undertaken in the context of a historic visitor site is described. The project offered different types of opportunity for scientific working, and involved four distinct groups of participants. Two distinguishing features of the different groups of participants were their…

The doctor of business administration (DBA) degree is widely considered as a professional doctorate or professional doctoral degree that is designed to prepare business practitioners. The doctor of philosophy (PhD) in business, by contrast, is thought to prepare research scholars and higher education faculty members. Prior research conducted by…

In the architectural design process, built precedent can be a valuable resource to shape design situations. Typology, the systematic categorisation of precedent, may act as a means to interpret this information and identify relationships between existing buildings and new design. This work explores the link between typology and the design process…

Propositional attitude verbs, such as "think" and "want," have long held interest for both theoretical linguists and language acquisitionists because their syntactic, semantic, and pragmatic properties display complex interactions that have proven difficult to fully capture from either perspective. This paper explores the…

The role of school leaders is particularly complex in today's "era of accountability," which involves high standards for student achievement alongside frequently changing educational systems. Research in the business field has found leader's cognitive complexity to be a predictor of leader and organizational effectiveness whereas the…

In this article, we extend the methodology of the Cut-Score Operating Function that we introduced previously and apply it to a testing scenario with multiple independent components and different testing policies. We derive analytically the overall classification error rate for a test battery under the policy when several retakes are allowed for…
