Short-term memory (STM) challenges are often observed in children with Down syndrome (DS), but existing early STM measures introduce measurement confounds in this population. To address the need for valid early STM measures for future DS interventions, this study evaluated the psychometric properties of a modified Corsi Span task, administered to…

Intellectual capital has aroused growing interest in higher education; however, one area for improvement in its study is how to measure it adequately. Therefore, it is necessary to have instruments based on current models of intellectual capital. This study aims to design and validate an intellectual capital measurement scale in accredited higher…

This paper describes the development and validation of the multidimensional Teacher Well-being Inventory underlined by a rational-empirical approach using teacher samples from China. A 20-item multidimensional instrument on teacher well-being was established with good psychometric characteristics. The results yielded five dimensions, which…

Postsecondary students' well-being is closely linked to success, which has predominantly been viewed from institutional perspectives rather than student experience. Addressing this gap, students and educators at a New Zealand postsecondary institution identified elements of overall success. Two existing measures were integrated with the…

Depression is a latent characteristic that is measured through self-reported or clinician-mediated instruments such as scales and inventories. The precision of depression estimates largely depends on the validity of the items used and on the truthfulness of people responding to these items. The existing methodology in instrumentation based on a…

The students…

Computational thinking (CT) in young children has recently gained attention. This study verified the applicability of the Korean version of the Bebras cards and TACTIC-KIBO in measuring CT among young children in South Korea. A total of 450 children responded to the Bebras cards, TACTIC-KIBO, and Early Numeracy tasks that were used for the…

Due to the increasing heterogeneity of students within learning groups at school, teachers are urged to appropriately address students' learning needs by means of differentiated instruction. Given that the successful and effective implementation of differentiated instruction relies mostly on teachers, research has extensively explored…

Creativity plays a vital role in enhancing students' performance in art and design education. The impact of motivation on education is a vital aspect that educators must take into account to promote the creativity of students. Therefore, this study aimed to explore the effect of students' motivation on their creative activities in Russian art and…

Background: The CAMDEX-DS is an instrument to diagnose Alzheimer's disease (AD) in Down syndrome consisting of an informant interview and a cognitive test battery (CAMCOG-DS). Measurement properties of the German CAMDEX-DS were investigated. Method: Fifty-five adults with Down syndrome (19-58 years) participated in this observational study.…

We have less time and focus than ever before, while the demand for attention is increasing. Therefore, it is no surprise that when answering questionnaires, we often choose to strongly agree or be neutral, producing problematic and unusable data. The current study investigated forced-choice (ipsative) format compared to the same questions on a…

Unfolding item response theory (IRT) models are important alternatives to dominance IRT models in describing the response processes on self-report tests. Their usage is common in personality measures, since they indicate potential differentiations in test score interpretation. This paper aims to gain a better insight into the structure of trait…

The present article describes the development and validation of the Informational and Normative Conformity Scale (SKI-N), a brief self-report tool capturing adolescents' general propensity to adopt a conformist attitude, and the underlying motives for doing so. The presentation includes a description of scale construction and an assessment of the…

Exploring the individual differences of the longitudinal growth of early numeracy (EN) in young children with Intellectual disabilities (IDs) prerequires the critical stage of exploring and validating the potential factor structure. Despite the fact that Relational Skills (RS), Counting Skills (CS) and Operations (O) are expected to constitute…

The purpose of this study was to adapt the Self Description Questionnaire for Preschoolers into Turkish and to examine the self-concept of Turkish preschoolers based on sex and age. A total of 420 preschoolers participated in the study. The viability of the six-factor solution for the Turkish sample was examined using the first- and second-order…
