Despite the importance of inclusion in education, studies that clearly define and operationalize the concept of early childhood inclusive education in South Korea remain scarce. In this study, we aimed to translate and validate a comprehensive measurement scale to assess Korean early childhood teachers' attitudes and perceptions regarding…

The current study examined the criterion validity of a computer adaptive universal screener with an end-of-year state mathematics assessment using extant data provided by a local education agency. Participants included 1,195 third through eighth graders. Correlational analyses were used to report predictive and concurrent validity coefficients for…

There is an increased demand for useful measures that capture students' math learning during intervention. Similarly, there is an awareness of the importance of researchers observing guidelines for study quality in publishing intervention results, including information related to outcome measures. We investigated the characteristics of outcome…

This paper reports on a design oriented study conducted in close collaboration between two researchers and three preschool teachers. Within this study, a play-based interview script was designed in accordance with theoretically driven principles. Based on this script, the preschool teachers conducted interviews with children from three preschools…

Over the past decades, the demand for scientific research to link theory and practice so that innovative solutions can be developed through research has steadily increased (Klees & Tillmann, 2015; Sandoval & Bell, 2004). In this context, the design-based research (DBR) approach was developed, which examines the research object and the…

Implementation fidelity is often thought of as a necessary condition to achieve internal validity and as having a relation to student outcomes. This relation is increasingly modeled; we reviewed reading intervention studies for students in pre-K-12 in which measures of implementation fidelity were included in final data analysis. A systematic…

Studies show that processes like teacher-child interactions are a key dimension of childcare quality and that global and domain-specific interactions seem to have different effects on child development. A variety of instruments have been used to assess quality in the field of early childhood research. The aim of this study was to identify and…

Research Findings: A growing number of stakeholders in early childhood education (ECE) rely on self-assessment to assess and improve the quality of ECE. In this systematic review, we investigated the reliability and validity of self-assessment in ECE, summarizing findings from 27 publications. We meta-analytically synthesized findings from 25…

Worldwide, there is growing recognition of the importance of science in early childhood education. Doing science or, more formally, "science and engineering practices," is acknowledged as a critical component of early science education that requires support from the adults in children's lives. Moreover, engaging in science practices…

This study examined the psychometric properties of the Chinese version of the Social-Emotional Assessment Measure (SEAM) (33-66 months), which is designed to assess social-emotional difficulties and behavior disorders in young children. In this case, the SEAM was translated and back-translated. The sample included 2477 preschoolers (1256 boys;…

Background: Well-being is a key aspect of children's education, yet measurement issues have limited studies in early primary school. Aims: The current 12-month longitudinal study assesses the temporal stability of child- and parent-reported school well-being and examines developmental links with academic self-concept and parent-rated prosocial…

The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

The study examines the validity of four commonly used early numeracy curriculum-based measurement (EN-CBM) tools in relation to math criterion measures. Additionally, the investigation examines the reporting quality of the included studies as related to important features of assessing CBM's technical adequacy. For inclusion in the meta-analysis,…

We investigated the reliability and construct validity of the Professionals' Perceptions about Collaborative Consultation in Early Childhood Intervention Scale (ProPerCECIS), a rating scale developed to measure collaborative consultation in early childhood intervention (ECI). ProPerCECIS was completed by 427 professionals from 78 ECI teams. The…

The purpose of this report is to investigate the feasibility of constructing a school-level measure of students' academic growth from kindergarten to grade 3, and to assess the validity and precision of that measure. The study measured schoolwide student growth for reading and math using student growth percentiles based on Maryland's 2014/15…
