Linkage plans are used when equating different test versions from different administrations of standardized achievement tests. The overall aim is to examine item response theory (IRT) observed-score equating when different linkage plans have been used when the average ability among test takers in different administrations and/or the average item…

Over the past 50 years, eight robust generalizations about intellectual precocity have emerged, been empirically documented, and replicated through longitudinal research. Within the top 1% of general and specific abilities (mathematical, spatial, and verbal) over one third of the range of individual differences are to be found, and they are…

This study focuses on the child adaptation processes of a group of 22 students who were identified in academic year 2011/12 as having high mathematical ability. The subjects' schooling and adaptation were tracked over six school years, with a specific psycho-pedagogical evaluation test in the final year to assess their adaptation via various…

School authorities, universities, and employers often schedule multiple tests on the same day or week, causing overlapping exam preparation and a dense testing schedule. This multitask learning can be intense, under pressure, and challenge the student's mental and physical perseverance. As a result, it can compromise performance relative to a more…

Intellectual impairments in preschoolers have been widely studied. A regularity that emerges is that children's intellectual impairments have an important impact on later adjustments in life. However, few studies have looked at the intellectual profiles of young psychiatric outpatients. This study aimed to describe the intelligence profile of…

This chapter offers an integrated review and discussion of the major advances in theory and practice in the area of literacy, with particular focus on the work since 2014 onward. For the purposes of this review, it approaches Literacy as the ability to read and write. For reading, the chapter highlights theoretical advances that expand the view of…

Despite the value of sense of purpose during older adulthood, this construct often declines with age. With some older adults reconsidering the relevance of purpose later in life, the measurement of purpose may suffer from variance issues with age. The current study investigated whether sense of purpose functions similarly across ages and evaluated…

Physical educators may be hesitant to adopt cooperative learning in their classes because they are concerned that a focus on socioemotional learning may reduce motor skill development. However, cooperative learning can increase physical activity engagement and interpersonal skills. This article demonstrates what cooperative learning can look like…

Based on the authors' wide reading in the field, this article suggests the notion of the narrative as a fitting and meaningful way of conceptualising and mapping the field of comparative education. Four prominent narratives can be identified in not only the field of comparative education (and the scholarly discourse on education) but also the…

This article proposes a duplex model for understanding giftedness. The first part of the duplex is the set of gifted skills and attitudes that one possesses as a result of heredity, the environment, and their interaction. It is the input that one has acquired from one's life experiences. The second part of the duplex is the utilization or…

We present the secondary-analysis of neurocognitive tests in the "Bumetanide in Autism Medication and Biomarker" (BAMBI;EUDRA-CT-2014-001560-35) study, a randomized double-blind placebo-controlled (1:1) trial testing 3-months bumetanide treatment ([less than or equal to] 1 mg twice-daily) in unmedicated children 7-15 years with ASD.…

This paper unpacks our efforts as external evaluators to work toward decolonizing our evaluation practice. Undertaking this writing exercise as a form of reflective practice demonstrated that decolonization is much more complex than simply translating materials, organizing locals to collect data, and building participants' capacity around Western…

The ability to recognize and construct nets is a fundamental aspect of spatial reasoning skills; however, there is a lack of understanding regarding effective instructional sequences for fostering this ability. The aim of this study is to test a Hypothetical Learning Trajectory for enhancing sixth-grade students' understanding of rectangular prism…

Spatial ability is defined as a cognitive or intellectual skill used to represent, transform, generate, and recall information of an object or the environment. Individual differences across spatial tasks have been strongly linked to science, technology, engineering, and mathematics (STEM) interest and success. Several variables have been proposed…

Exploring individual differences and looking beyond averaged parameters of early numeracy in young children with mild intellectual disabilities has become an area of interest to many researchers worldwide. This study aimed to identify the different profiles of early numeracy skills in young children with mild intellectual disabilities. For this…
