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…

Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal…

Individuals with autism spectrum disorder (ASD) present difficulties in forming relations among items and context. This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular…

This article explores the relationship between toddlers' (age: 30-33 months) well-being (WB), play (PL), social-emotional competence (SC) and movement skills (MS). Two hypotheses were put forward for testing: (1) there is a significant positive correlation between WB, PL, SC and MS, and (2) toddlers' WB can be predicted from their PL, SC and MS.…

The purpose of the research is applied research, it is a development branch, and in terms of the nature and method, it is a causal-comparative research. The statistical…

Although the literature on institutional diversity suggests that quality assurance practices could affect institutional diversity, there has been little empirical research on this relationship. This article seeks to shed some light on the possible connection between quality assurance practices and institutional diversity by examining the…

The study addresses the social participation of integrated students with special educational needs (SEN) in upper primary regular classes in Greece alongside their perceptions of best friend quality. Social participation was defined as consisting of four key dimensions: students' acceptance by classmates, friendships, social self-perceptions, and…

This research analyzed the influence of socioeconomic variables in the L2 learning in beginner students of level one in a language center in a public university in Babahoyo. In addition, variables such as parents' level of education and home environment are analyzed in order to determine the relationship between these variables with L2 learning.…

Functional assessment and functional analysis are processes that have been applied successfully in work with people who have developmental disabilities, but they have been used rarely with students who experience emotional or behavioral disorders. In the present study, five students in elementary school programs for severe emotional disturbance…

This paper presents the experienced difficulties of students participating in the multidisciplinary, remote collaborating engineering design course challenge-based innovation at CERN. This is with the aim to identify learning barriers and improve future learning experiences. We statistically analyse the rated differences between distinct design…

Introduction: The macroscopic perspective is one of the frameworks for research on problem solving in mathematics education. Coming from this perspective, our study addresses the stages of thought in mathematical problem solving, offering an innovative approach because we apply sequential relations and global interrelations between the different…

The purpose of this study was to establish the extent to which biology scientific creativity skills are influenced by the students' culture and gender in Turkana County. A mixed method research design was used. This involved cross sectional survey and ethnographic study. The target population comprised all form three students in sub county schools…

Relatively little is known about patterns of school-based supportive services for youth with autism spectrum disorder. This study describes these supportive services and their correlates, both cross-sectionally and retrospectively, in a large sample (N = 283) of 6- to 18-year-old youth. To assess whether special education designation and classroom…

Electrodermal activity was examined as a measure of physiological arousal within a naturalistic play context in 2-year-old toddlers (N = 27) with and without autism spectrum disorder. Toddlers with autism spectrum disorder were found to have greater increases in skin conductance level than their typical peers in response to administered play…

The aims of this study were (1) to understand the effects of parents' education and personality aspects on child disruptive behavior, (2) to know the correlation between the parents' personality aspects (N-Deference, N-Succorance, N-Dominance and N-Aggression) and the children' disruptive behavior. A quantitative approach to the correlational…
