Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times. Reliability is about making sure that different test forms…

The focus of this study was to examine peer-reviewed 'draw-a-scientist' test (DAST) research studies conducted primarily in the USA. In a similar review of science education research into the 'nature of science views', it was found that race played a prominent role in that research agenda and therefore may be impacting DAST research as well. Using…

The present study has two main purposes. The first is to create a short form of the BTPS and to evaluate the psychometric properties of the short form. The second is to evaluate the performance of the ant colony optimization procedure and discuss the applicability of the ant colony optimization procedure in creating a short form. Results revealed…

This paper is about attitudes toward sign languages. The paper presents an idea to help make sign language surveys better in the future. In 2018, UNESCO (the United Nations Educational, Scientific and Cultural Organization) published a sign language survey and a spoken language survey together for the first time. This was very important to show…

Approaching assessment from an end-to-end perspective helps with appropriate assessment selection, design, and practice. Thinking in terms of end-to-end reminds teachers to keep in sight the aspirations (or ends) associated with any assessment activity. It also helps teachers to consider how to integrate assessment activities and capabilities into…

Creative orientation is the extent to which different individuals are drawn toward creative activities (e.g., art, music). We know relatively little about child-level creative orientation given certain testing limitations. Adult tools often measure time spent engaged in creative pursuits, but this method is unsuitable for children because their…

This paper describes a process to define a comprehensive list of exemplars for seven core Diagnostic and Statistical Manual (DSM) diagnostic criteria for autism spectrum disorder (ASD), and report on interrater reliability in applying these exemplars to determine ASD case classification. Clinicians completed an iterative process to map specific…

Coefficient alpha reliability persists as the most common reliability coefficient reported in research. The assumptions for its use are, however, not well-understood. The current paper challenges the commonly used expressions of coefficient alpha and argues that while these expressions are correct when estimating reliability for summed scores,…

This article reviews the administrative, scoring, and psychometric properties of the Wechsler Individual Achievement Test, Fourth Edition (WIAT-4, NCS Pearson, 2020). The WIAT-4 is one of the more commonly administered broadband measures of academic achievement. The instrument was determined to be well-conceptualized, and generally…

How frequently should pupils be tested in a given school year using standardized tests? Perhaps, once in a given school year which makes it possible for parents and teachers to notice how a child compares with cohorts in the nation in a specific school year. The results need careful reviewing in order to assist in making curricular decisions. Each…

Following the Khmer Rouge takeover of Cambodia in 1975, "Year Zero" became the beginning of the destruction of the previous regime, many of its officials and teachers, and its education system. With the expulsion of the Khmer Rouge in 1979, the Ministry of Education, Youth and Sports (MoEYS) faced a massive task of rebuilding an…

As technologies have been improved, item preknowledge has become a common concern in the test security area. The present study proposes an unsupervised-learning-based approach to detect compromised items. The unsupervised-learning-based compromised item detection approach contains three steps: (1) classify responses of each examinee as either…

Written examinations represent one of the most common assessment tools in education. Though typically perceived as measurement instruments, written examinations are primarily texts that perform a communicative function. To complement existing research, this study viewed written examinations as a distinct form of communication (i.e. 'register').…

Students come into the classroom with a variety of background knowledge. Therefore, it is imperative that educators are able to help all students, regardless of their familiarity with the content. Since it can be challenging for some large enrollment classes to schedule recitation classes after lectures due to logistical constraints, this study…

Instructional videos for teaching second language (L2) vocabulary often feature an instructor onscreen. The instructor in the video may involuntarily produce beat gestures with their hands, as occurs in real teaching settings. Beat gestures highlight key information in speech by conveying the rhythm of the language, but do not themselves convey…
