The Wechsler Intelligence Scale for Children (WISC) is the most widely used intelligence test in the world. Now in its fifth edition, the WISC-V has been translated and adapted for use in nearly a dozen countries. Despite its popularity, numerous concerns have been raised about some of the procedures used to develop and validate translated and…

The Council on Social Work Education (CSWE) issued new requirements for social work educational programs in 2015, identifying a new set of competencies for students to be effective social work professionals. Social work programs are expected to measure students' competencies to demonstrate the effectiveness of their education. However, few…

This study aimed to examine the effect of using items from previous exams on students? pass-fail rates and on the psychometric properties of the tests and items. The study included data from 115 tests and 11,500 items used in the midterm and final exams of 3,910 students in the preclinical term at the Faculty of Medicine from 2014 to 2019. Data…

Since its introduction in 2017, National Foundation for Educational Research (NFER) has been contracted by Ofqual to develop, deliver and analyse the results of the National Reference Test (NRT) in English and maths. The NRT is administered annually and shows if student performance in English and maths at GCSE level has changed from year-to-year.…

The second version of Kaiser's Measure of Sampling Adequacy (MSA[subscript 2]) has been widely applied to assess the factorability of data in psychological research. The MSA[subscript 2] is developed in the population and little is known about its behavior in finite samples. If estimated MSA[subscript 2]s are biased due to sampling errors,…

Introduction: The examination of variables such as resilience and mindfulness, which may help adolescents who are enrolled in distance education cope with test anxiety, is important in terms of reducing test anxiety and increasing the efficiency of distance education. For this reason, it was aimed to examine the mediating role of mindfulness in…

Children with gifted intellects often earn lower scores on measures of processing speed than their nongifted counterparts. However, neuropsychological research indicates such a profile of scores is likely not due to a true innate neurocognitive processing speed deficit but is rather a statistical artifact resulting from the interference of common…

The performance of standardized tests is an ongoing matter of concern for childhood researchers. Standardized tests are often described as neglecting the ethical complexities of doing research with young children. However, this critique is primarily presented in general terms, and does not attend to the locality and specificity of particular test…

Since the retina shares its embryological origin with the central nervous system, optical coherence tomography (OCT), an imaging technique frequently employed in ophthalmology to analyze the macula and intraretinal layer thicknesses and volumes, has recently become increasingly important in psychiatric research. We examined 34 autistic and 31…

Current challenges in early identification of autism spectrum disorder lead to significant delays in starting interventions, thereby compromising outcomes. Digital tools can potentially address this barrier as they are accessible, can measure autism-relevant phenotypes and can be administered in children's natural environments by non-specialists.…

Background: Many children experience delayed or missed identification of an intellectual disability diagnosis, meaning that key opportunities for early educational intervention may be lost. Methods: Semi-structured interviews were used to explore the views of teachers, parents, and clinicians (n = 22), about the use of the Child and Adolescent…

The Miller-Rabin test is a useful probabilistic method for finding large primes. In this paper, we explain the method in detail and give three variations on this test. These variations were originally developed as student projects to supplement a course in error correcting codes and cryptography.

This study aims to determine the need for multitiered diagnostic instruments to identify misconceptions and their causes, as well as multi-representational profiles in chemistry lessons starting from grade 10 in the initial to the final material for grade 12. The data analysis technique used in this research is descriptive, namely descriptive…

The purpose of this study is to explore the psychometric properties of the Utrecht Work Engagement Scale-9 (UWES-9) using both Classical Test Theory (CTT) and Item Response Theory (IRT) approaches, with a sample of practicing school counselors (N = 356). The results of analyzing the UWES-9 included information on item-level statistics, internal…

The Forms of Bullying Scale was introduced in 2013 and was normed with a large group of Australian students aged 12 to 15 (Shaw et al., 2013). To date, no researchers have attempted to validate FBS on adolescents in the United States. The purpose of this paper is to provide validation for the Forms of Bullying Scale -- Perpetration (FBS-P; Shaw et…
