This study examined the exchangeability of total scores (i.e., intelligent quotients [IQs]) from three brief intelligence tests. Tests were administered to 36 children with intellectual giftedness, scored live by one set of primary examiners and later scored by a secondary examiner. For each student, six IQs were calculated, and all 216 values…

Soles of the Feet for Students (SOF) has demonstrated effectiveness at increasing academic engagement among general education students. This work intended to replicate and extend previous work by exploring the effectiveness and social validity of SOF among students receiving special education services, who had low levels of academic engagement and…

Individuals on the autism spectrum face stigma that can influence identity development. Previous research on the 22-item Autism Spectrum Identity Scale (ASIS) reported a four-factor structure with strong split-sample cross-validation and good internal consistency. This study reports the discriminative and criterion validity of the ASIS with other…

This study compared the reliability, validity, and measurement properties of the "Supports Intensity Scale-Children's Version" (SIS-C) in children with autism and intellectual disability (n = 2,124) and children with intellectual disability only (n = 1,861). The results suggest that SIS-C is a valid and reliable tool in both populations.…

Mixed methods approach has developed into the third methodological movement in educational research. Validity in mixed methods research as an important issue, however, has not been examined as extensively as that of quantitative and qualitative research. Additionally, the previous discussions of validity in mixed methods research focus on research…

In the context of college admissions, the current study examined whether differential prediction of first-year grade point average (FYGPA) by gender could be explained by an omitted variable problem--namely, academic discipline, or the amount of effort a student puts into schoolwork and the degree to which a student sees him/herself as hardworking…

Early ASD screening has the potential to reduce delays between initial parental concerns and diagnosis, and promote early intervention. The aim of this study was to validate the M-CHAT on a French population sample of 24 month-old children. This study included a low-risk sample of 1,227 children. A total of 20 children screened positive on the…

The application of game-based learning adds play into educational and instructional contexts. Even though there is a lack of standard methodologies or formulaic frameworks to better inform game-based intervention development, there exist scientific and empirical studies that can serve as benchmarks for establishing scientific validity in terms of…

The validity and reliability of the Test of Gross Motor Development-3 (TGMD-3) were measured, taking into consideration the preference for visual learning of children with autism spectrum disorder (ASD). The TGMD-3 was administered to 14 children with ASD (4-10 years) and 21 age-matched typically developing children under two conditions: TGMD-3…

This article examines college student disengagement from sports, presents a multidimensional concept of athletic identity, and introduces a new measure intended to assist college counselors in their work with disengaged athletes. The Multidimensional Athletic Identity and Engagement Scale (MAIES) is introduced (Cronbach alpha 0.98, with subscale…

Objectives: Integration of children's individualized behavioral learning objectives into ongoing activities, routines, and transitions of preschool classrooms has been a recommended practice for many years in the field of early childhood special education. This study examined the effectiveness of embedded instruction in teaching three functional…

In this study, we investigated the factor structure underlying the TAP System for Teacher and Student Advancement using confirmatory and exploratory factor-analytic methods and under conditions of multilevel (nested) data structures and ordinal measurement scales. We found evidence of generally poor fit with the system's posited first-order,…

Dynamic assessments in general, and game-based assessment (GBA) specifically, compel us to rethink prevailing language testing conceptualizations of context. Context has traditionally been portrayed with a cognitive orientation, which focuses on static abilities, ignores complex interactions, devalues the role of tasks in determining scores, and…

The aim of this study was to develop a three-tier concept test to determine high school students' conceptual understanding in terms of chemical bonding, and at implementing a reliability and validity study for the test. A total of 175 high school students participated in the research. A three-tier test of 15 questions was employed in the study.…

Healthcare administration is a complex, multifaceted career path that requires constant adaptation and integration of external guidance. Organizations seeking the most qualified and skilled candidates draw from a multitude of applicants without having a single potential success indicator. The lack of a standard educational background,…
