The maximal reliability of a congeneric measure is achieved by weighting item scores to form the optimal linear combination as the total score; it is never lower than the composite reliability of the measure when measurement errors are uncorrelated. The statistical method that renders maximal reliability would also lead to maximal criterion…

Background: Mortality studies can help reduce health inequalities by informing public policy through a better understanding of causes of death and comorbidities. Mortality studies often rely on Medical Certificates of Cause of Death (MCCD) for data. Method: A systematic review was undertaken to identify the extent and nature of issues in recording…

Research on self-efficacy has provided evidence that it is a moderating factor that positively impacts students' choices to pursue and persist in engineering. Engineering graphics is seen as the preferred method of communication for the profession, yet to date no instrument is available that measures students' self-efficacy as it relates to…

The Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) is used to assess auditory development in young children with hearing loss. Despite being widely used, previous research showed that its psychometric properties are not ideal. As a first step toward psychometric advancements of the IT-MAIS, this study aimed to create videos with…

The scope this article was to develop an instrument to measure Chemistry students' ability regarding 'physical bonding' and to validate it. A number of 24 items were developed by mapping items to cognitive levels described by the Marzano taxonomy. A number of N=73 students were evaluated. Four items exhibited a MNSQ >1.3 and were eliminated…

This study developed an abbreviated form of Barron's (1953) Ego Strength Scale for use in research among college student samples. A version of Barron's scale was administered to 100 undergraduate college students. Using item-total score correlations and internal consistency, the scale was reduced to 18 items (Es18). The Es18 possessed adequate…

Purpose: In this letter, the authors respond to Pavelko and Owens' (2017) newly advanced set of procedures for language sample analysis: Sampling Utterances and Grammatical Analysis Revised (SUGAR). Method: The authors contrast some of the new guidelines for transcription, morpheme segmentation, and language sample elicitation in SUGAR with…

The use of assessments that require rater judgment (i.e., rater-mediated assessments) has become increasingly popular in high-stakes language assessments worldwide. Using a systematic literature review, the purpose of this study is to identify and explore the dominant methods for evaluating rating quality within the context of research on…

Although inter-rater reliability is an important aspect of using observational instruments, it has received little theoretical attention. In this article, we offer some guidance for practitioners and consumers of classroom observations so that they can make decisions about inter-rater reliability, both for study design and in the reporting of data…

The aim of this study is to adapt the Gamification User Types Hexad Scale (GUTHS) created based on Marczewski's(2015) user type hexad framework and validated by Tondello et al. (2016) into the Turkish context. The original scale consists of six dimensions, each of which has four items. The dimensions -- and the user types that they refer to -- are…

Recent advances in information and communication technologies (ICT) have resulted in improvements in the delivery of education. It is a wellknown fact that learning technologies currently have a pivotal role in education. Amongst them, Virtual Learning Environments (VLEs) are widely used in education. The role of VLEs in improving quality and…

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design…

Though panel data are increasingly used in the social sciences, the question whether repeatedly participating in a panel survey affects respondents' attitudes and (response) behaviour is still largely unsolved. Drawing on a model of associative networks that is extended by assumptions on survey satisficing, we present a theoretical framework that…

A consistent mentoring approach is key to unlocking the full benefits of mentoring, ensuring effective oversight of mentoring relationships and preventing abuse of mentoring. Yet consistency in mentoring between senior clinicians and medical students (novice mentoring) which dominate mentoring processes in medical schools is difficult to achieve…

Students' perceptions of their classroom climate have been found to relate significantly to students' learning outcomes. The purpose of the present study was to construct an instrument for assessing elementary-school students' perceptions of classroom climate, based on a previous instrument that was being used in Chile by a public national school…
