Women and students of minority race/ethnicity continue to be underrepresented in many science and engineering fields. Access to special programs, mentors, and internships may influence awareness, intention, and persistence in science and engineering. This dissertation investigates the experiences, beliefs, and career intentions of undergraduate…

Purpose: Language sampling analysis (LSA) plays an important role in evaluating language skills; hence, the study aimed to develop new assessment measures for the LSA in Turkish as alternatives to mean length of utterance (MLU) and the Language Assessment, Remediation and Screening Procedure. With this aim, Developmental Sentence Scoring (DSS) and…

A conceptual framework for empirical research on the impact of NASA Space Science Education Consortium (NSSEC) activities is presented in this paper, along with a cross-referencing system between the NSF-based NSSEC evaluation framework and historical definitions of comparable psychometric constructs in the literature. A selected set of findings…

Objectives: Despite advances in understanding associations among attention-deficit hyperactivity disorder (ADHD), emotion dysregulation (ED), and related outcomes, there is incongruity between ADHD-relevant conceptualizations of ED and available measures of ED. To assess the psychometric properties of a parent-report questionnaire of ED…

This study aims to develop a measurement tool that will enable the determination of school administrators' and teachers' opinions on educational technologies. The items prepared by scanning the literature were presented to the opinions of the experts. Following the opinions, the 51-item trial form was applied to a total of 406 administrators and…

The effect of guessing on the point estimate of coefficient alpha has been studied in the literature, but the impact of guessing and its interactions with other test characteristics on the interval estimators for coefficient alpha has not been fully investigated. This study examined the impact of guessing and its interactions with other test…

During this research study the "Self-Advocacy Assessment Tool for Preschool-Aged Children with Hearing Loss: Birth to Age 4" was developed, constructed, and evaluated. The study provides content, construct and internal consistency reliability and validity evidence. The Self-Advocacy Assessment Tool is the first tool specifically designed…

Science education is believed to be a vital tool for individual and societal development at large. The persistent low levels of students' achievement in sciences at the various public examinations in Nigeria have continued to draw the attention of major stakeholders in education. This study examined academic achievement of Senior Secondary School…

The purpose of this study was to investigate (a) the validity and reliability of the inclusive Self-efficacy Instrument for Physical Education Teacher scale (SE-PETE-D), using a Lithuanian physical education (PE) teachers' sample, and (b) the impact of type of disability and personal attributes. The English version of the scale was translated into…

Context-based learning (CBL) approaches have been recommended and expanded in science education to make science more relevant to students by connecting science content with students' daily life. Subsequently, in order to implement CBL at school, a group of scenarios has been produced by several stakeholders. However, there is a lack of resources…

The current study aimed to adopt and assess the psychometric properties and measurement invariance of Grit-S among Omani and American students (N = 487) using Exploratory Factor Analysis (EFA) and Multi-Group Confirmatory Factor Analysis (CFA). The scale's construct validity was estimated by investigating its associations with achievement goal…

Self-regulatory abilities have been shown to be closely linked to academic success. There are a variety of measurement tools to assess self-regulated learning in pupils and students. Crucially, preschool age marks a sensible period for the maturation of self-regulated learning (SRL) and related abilities such as executive-control functions (EF).…

Recent advances in policy development and professional practice in the field of early learning and child care have led to the expectation that it is appropriate and advantageous to include children with disabilities and extra support needs in early child care and learning programs. Yet, to date, evidence-based research on the effects of…

Learning problems (LP) can have wider implications than the academic deficits per se. The goal of the present series of studies was to develop a reliable and valid quality-of-life measure targeted to children and adolescents with LP. In Study 1, using a 35-item questionnaire, we surveyed 151 parents/guardians of children referred for assessment of…

Psychometric properties of the 30-item Family Resource Scale (FRS) were examined in a sample of families seeking assistance for their child's behavioral difficulties (N = 300). The FRS is a measure that assesses the adequacy of family resources across several contexts including intra-family support and personal resources. Our analyses supported a…
