In this research, a new test for understanding simple fractions has been developed for students at the beginning of lower secondary education. In many countries, mathematics education in Grade 5 builds on elementary students' developing concepts of fractions. Understanding fractions causes many difficulties for students, and research on mental…

Purpose: Aphasia fluency is multiply determined by underlying impairments in lexical retrieval, grammatical formulation, and speech production. This poses challenges for establishing a reliable and feasible tool to measure fluency in the clinic. We examine the reliability and validity of perceptual ratings and clinical perspectives on the utility…

School climate measures are important tools that assist educators in evaluating the "norms, values, and expectations that support people feeling socially, emotionally and physically safe" (National School Climate Council, 2007, p. 4). Positive school climate is associated with academic performance indicators such as grade point average,…

The growing interest of educational researchers in computational thinking (CT) has led to an expanding literature on assessments of CT skills and attitudes. However, few studies have examined whether CT attitudes influence CT skills. The present study examines the relationship between CT attitudes and CT skills for preservice teachers (PSTs). The…

The current paper aims at developing and validating a Teacher Leadership Inventory (TLI). Adopting the theoretical-empirical strategy of instrument development, the procedure consisted of taking a sample of panel experts and undertaking six sequential empirical studies with sufficient samples of teacher leaders from China. After verifying content…

Many researchers have separately developed instruments to measure environmental characteristics such as attitudes, values, and knowledge. However, there is no instrument used to measure all these aspects in one comprehensive instrument. This study is meant to develop and validate a green character instrument which reveals student behavior and…

This study examined the reliability and validity of the 13-item Classroom Observation Scale as used by teachers and non-clinically trained observers to identify children who more likely than their peers to have autism spectrum disorder in less-resourced preschools. A total of 534 children (ages 2;10 to 4;5, Mean = 3;8) from nine Chinese-language…

Test fairness is critical to the validity of group comparisons involving gender, ethnicities, culture, or treatment conditions. Detection of differential item functioning (DIF) is one component of efforts to ensure test fairness. The current study compared four treatments for items that have been identified as showing DIF: deleting, ignoring,…

Home-based parental involvement in early education is linked to beneficial outcomes in children's development and may redress unequal educational outcomes associated with family background. The type of educational activities at home and the way parents provide their support may differ across parents with and without a migration background. It is…

The purpose of this study was to adapt a survey developed by Chai, Jong et al. (2019) on technological pedagogical STEM (TP-STEM) knowledge into Turkish and to determine the knowledge of pre-service and in-service teachers about TP-STEM. The original survey consisted of four factors and a total of 17 items. These factors included Technological…

Objectives: The aim of this study was to develop a scale measuring inclusive school quality from parents' perceptions (Parents' perceptions of Inclusive School Quality, PISQ) and investigate the perceptions of Chinese parents of children with disabilities of inclusive school quality using the PISQ scale. Method: The data for 78 parents of children…

Rasch Analysis suggested the Lakaev Academic Stress Response Scale-1 (LASRS-1) would benefit from refinement by the addition of items and changes to the wording of other items. It was named the LASRS-2 and contained Four Domains (Affective, Behavioral, Cognitive, and Physiological). Rasch Model Analysis tested construct validity and internal…

The purpose of this research is to adapt the Teacher Perceptions of Grading Practices Scale into Turkish and to examine the measurement invariance. This scale, which examines teachers' perceptions of grading methods, has six components: importance, usefulness, student effort, student ability, teachers' grading patterns, and perceived self-efficacy…

In this survey study, it is aimed to develop a valid and reliable scale that can measure multicultural teacher competencies of primary teachers and to examine their multicultural teacher competencies. Three different participant groups were determined by convenience sampling technique. With 336 primary teachers exploratory factor analysis (EFA),…

Computational thinking is recognized as a vital skill related to problem-solving in technological and non-technological fields. The existence of different sub-domains related to this skill has been pointed out. Therefore, there is a need for tools that measure these different sub-domains. Because of its structure that includes different skills,…
