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…

In this study, evaluative case study was used to determine the realization level of the outcomes in the 10th chemistry curriculum. The 23 outcomes in the 10th grade chemistry curriculum were analyzed by two researchers. In order to determine the realization of the achievements based on practice, a chemistry teacher who attended the 10th grade…

Digital game-based assessments generate student process data that is much more difficult to analyze than traditional assessments. The formative nature of game-based assessments permits students, through applying and practicing the targeted knowledge and skills during gameplay, to gain experiences, receive immediate feedback, and as a result,…

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.

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…

Obsessive-compulsive disorder (OCD) in adolescents is understudied in Italy. This study evaluated the Italian Obsessive Compulsive Inventory--Child Version (OCI-CV) and its predictive validity on OCD symptoms at 1-year-follow-up, an aspect that was not investigated by previous international research. Use of OCI-CV in schools might enhance early…

Researchers and practitioners have questioned whether scoring procedures used with curriculum-based measures of writing (CBM-W) capture growth in complexity of writing. We analyzed data from six independent samples to examine two potential scoring metrics for picture word CBM-W (PW), a sentence-level CBM task. Correct word sequences per response…

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…
