Empirical research on number sense to date has been conducted with preschoolers and elementary school students. Despite their contributions to the literature, these studies have used variable-centered analytic approaches that may prevent distinct number sense profiles for preschoolers and first graders from being identified. This study aimed to…

Throughout the world scientific reasoning (SR) is a valuable and desirable ability to gain deeper understanding of science in all grade level. In the current study, we first adapted the SPR-I (7) which consists of seven items with three sub-dimensions as the experimentation, the understanding the nature of science (NOS) and the data…

A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

Purpose: This paper aims to introduce a novel AI learning progression for upper-elementary students and aligns assessment items across levels of each construct to gather evidence of understanding. It also validates this quantitative measure by examining these items as two subscales for psychometric properties using the Rasch model.…

In primary schools, the incorporation of STEAM education has become a widespread trend, as it is believed to have the potential to enhance the quality of education and foster students' competencies. This investigation aimed to explore the definition, measurement model, and scale of students' STEAM competence, emphasizing their hands-on experiences…

The objective of this study was to understand the psychometric functioning of the Child Anger Regulation Measure (CARM), its prediction of emotional engagement, and if the prediction of emotional engagement differs for girls and boys. The sample included 251 upper-elementary school students in the United States (10% Black, 62% White, 6% Latinx, 5%…

Afterschool settings have continued to be identified as an ideal outlet for supporting youth development in many arenas, including physical activity (PA) behaviors and social emotional learning (SEL) skills. In fact, PA centered programs are ideal settings for youth to 8 develop and practice SEL skills in authentic ways. However, there a several…

This research study holds practical significance for educators, school administrators, and mental health professionals. The study utilized structural equation modeling on two samples of elementary school students in grades three to five to create and validate condensed versions of the Social-Emotional Health Survey-Primary and the Me and My School…

Parental educational anxiety, which refers to the anxiety and stress they experience about their children's academic performance, learning processes, and educational environments, has become an important research topic in recent years. In this context, developing or adapting scales for understanding parents' concerns to different cultures is of…

The present study examines the psychometric properties of the long form (LF) of the Greek translation of the Friendship Quality Questionnaire (FQQ), a widely recognized self-report instrument that assesses children's perceptions of the qualities of their friendships. Four hundred seventeen (417) typically developing primary-school students (50.8%…

Although the impact of non-cognitive factors, such as math anxiety, math test-taking anxiety, and attitudes toward mathematics, has been extensively studied, this area remains partially unexplored in the realm of national assessments. This research focuses on the analysis of the validity and reliability of an 11-item questionnaire introduced by…

The Theory of Successful Intelligence defines intelligence as the integrated set of abilities and competencies in specific domains needed to attain success in life. Informed by this theory, we examined the dimensionality, reliability, and validity of an augmented intelligence test, Aurora-a, a 17-subtest assessment of analytical, practical, and…

Since classroom climate is inherently a group level phenomenon, we argue that measures shown to be valid and reliable in multi-level settings are needed. We propose a brief, 5-item measure of classroom climate and demonstrate its reliability and validity in multi-level structural equation models. The measure demonstrated good reliability and we…

Background: Difficulties identifying anxiety disorders in primary-school aged children present significant barriers to timely access to support and intervention. This study aimed to develop a brief assessment tool that can identify children with anxiety disorders in community settings, with a high level of sensitivity and specificity. Methods:…

Schools carry the important task of fostering democratic values like equality and tolerance among students. This study examined to what extent a valid and reliable measurement instrument can be developed to gain insight into students' attitudes towards democratic values and what can be concluded based on this measurement. We constructed the…
