Purpose: The aim of the study was to address the reported inconsistencies in the relationship between objective acoustic measures and perceptual ratings of vocal quality. Method: This tutorial moves away from the more widely examined problems related to obtaining the perceptual ratings and the acoustic measures and centers in less scrutinized…

The Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V; Wechsler 2014a) "Technical and Interpretation Manual" (Wechsler 2014b) dedicated only a single page to discussing the 10-subtest WISC-V primary battery across the entire 6 to 16 age range. Users are left to extrapolate the structure of the 10-subtest battery from the…

Background: There is paucity in availability of valid and reliable measures of psychopathology that can be routinely applied with an intellectual disability (ID) population in clinical practice. The psychometric properties of the Clinical Outcome Routine Evaluation-Learning Disabilities 30-Item version (CORE-LD30) are examined. Method: The…

In this ITEMS module, we provide a two-part introduction to the topic of reliability from the perspective of "classical test theory" (CTT). In the first part, which is directed primarily at beginning learners, we review and build on the content presented in the original didactic ITEMS article by Traub and Rowley (1991). Specifically, we…

In two experiments, undergraduate students read short texts containing two embedded sources that could either agree or disagree with each other. Participants' memory for the sources' identity (i.e., occupation) and features (i.e., the source's access to knowledge and the source's physical appearance) was examined as a function of the consistency…

To examine the reproducibility of three measurement techniques used to determine creatine kinase, interleukin-6 and high-sensitivity C-reactive protein, 50 participants had blood samples taken on two occasions. Fingertip plasma samples were analysed using the Reflotron for CK determination. Venous blood samples collected into serum separator tubes…

The purpose of this article was two-fold (1) provide an overview of the commonly reported and under-reported absolute agreement indices in the kinesiology literature for continuous data; and (2) present examples of these indices for hypothetical data along with recommendations for future use. It is recommended that three types of information be…

Measurement models need to properly delineate the real aspect of examinees' response processes for measurement accuracy purposes. To avoid invalid inferences, fit of examinees' response data to the model is studied through "person-fit" statistics. Misfit between the examinee response data and measurement model may be due to invalid…

Computational thinking (CT) has been recognized as an essential part of every child's education (Wing, 2006) and Bebras contest items have been frequently used to measure CT. Think alouds has emerged as a prominent method for identifying thought processes and correcting problems with assessments. As little research has examined validity evidence…

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…

One of the questions with the longest history in educational assessment is whether it is possible to increase the reliability of a test simply by altering the way in which scores on individual test items are combined to make the overall test score. Most usually, the score available on each item is communicated to the candidate within a question…

Introduction: The objective of this work is to present the results of the adaptation and validation process of the Motivated Scale Learning Questionnaire (MSLQ) in university students in Colombia. Method: The research is framed in the so-called instrumental studies, which seek to adapt, validate and analyze the psychometric properties of an…

Secondary education students do not usually perceive history as a subject connected with their lives, backgrounds and interests. At the same time, prospective and in-service teachers do not always have a coherent vision of this discipline, which can reflect on their students' perceptions. This study makes use of a theoretical framework developed…

This study investigated lecturers' perception of contributory pension scheme implementation and job commitment in South-South Nigerian universities. To guide the study, two research questions and one hypothesis were raised. A descriptive survey research that adopted correlational design. The population of the study was all the lecturers in the six…

Teacher-student relationships have been studied with increasing intensity during the past three decades, but the majority of this study has focused on young children and has relied on teacher perceptions of these relationships. The current study was designed to add to this growing body of research by exploring the factor structure, reliability,…
