Successful integration of mobile learning (m-learning) technologies in education primarily demands that teachers' perception of such technologies should be determined. Therefore, the perceptions of teachers are of great significance. There is no available instrument that assesses teachers' perceptions of m-learning. Our research provided the first…

Family Adaptability and Cohesion Evaluation Scale (FACES) IV was developed to tap the full continuum of the cohesion and flexibility dimensions from the Circumplex Model of Marital and Family Systems. Six scales were developed, with two balanced scales and four unbalanced scales designed to tap low and high cohesion (disengaged and enmeshed) and…

Many well-known equations in classical test theory are mathematical identities in populations of individuals but not in random samples from those populations. First, test scores are subject to the same sampling error that is familiar in statistical estimation and hypothesis testing. Second, the assumptions made in derivation of formulas in test…

Standardized scales to evaluate qualities of trunk movements in children with dysfunction are sparse. An examination of the reliability of scales that may be useful in the clinic is important. The aim of this study was to examine the reliability of the Trunk Impairment Scale (TIS) for children with cerebral palsy (CP). Standardized scales are…

Background: Emotional/psychological child maltreatment (ECM) is a major public health problem with serious consequences including emotional and behavioral problems. Nevertheless, ECM is an understudied area. Objectives: The aims of this review are to identify measures of ECM and to evaluate their psychometric properties and utilities. We provide a…

This article reports on the development and the exploration of the underlying psychometric properties of the School Counselor Self-Advocacy Questionnaire, a measure of skills school counselors can use to advocate for their roles and programs. An exploratory factor analysis (N = 188) suggested a unidimensional model, and a confirmatory factor…

A standardized protocol for a pediatric heel-rise test was developed and reliability and validity are reported. Fifty-seven children developing typically (CDT) and 34 children with plantar flexion weakness performed three tests: unilateral heel rise, vertical jump, and force measurement using handheld dynamometry. Intraclass correlation…

The purpose of this study was to investigate the reliability and perceived pedagogical utility of a multidimensional weighted performance assessment rubric used in Kansas state high school large-group festivals. Data were adjudicator rubrics (N = 2,016) and adjudicator and director questionnaires (N = 515). Rubric internal consistency was…

It is important to explore score reliability in virtually all studies, because tests are not reliable. The present paper explains the most frequently used reliability estimate, coefficient alpha, so that the coefficient's conceptual underpinnings will be understood. Researchers need to understand score reliability because of the possible impact…

In 1991, Herbert Kohl argued against the inaccurate and incomplete story of Rosa Parks and the Montgomery Bus Boycott that appeared prominently within texts and trade books of that era (Kohl 1991). He contended the biased perspective stripped Montgomery's African American community of their courage, intelligence, and moral conviction. Kohl…

The goal of this study was to develop a measure of creativity that builds on the strengths of youth with autism spectrum disorders (ASD). The assessment of creativity focused on the visual-spatial abilities of these youth using 3D modeling software. One of the objectives of the research was to develop a measure of creativity in an authentic…

The aim was to analyze the psychometric properties of "Sexuality and the Mental Retardation Attitude Inventory" (SMRAI) in a sample of 144 psychology college students 2nd to the 9th, of a private university in Lima, of which 44 were males (30.6%) and 100 female (69.4%), aged between 17 and 43 years (average: 21.9). The confirmatory…

In a world characterized by interconnectedness and interdependence, it is essential that teachers are able to effectively teach with a global perspective. To that end, it is necessary for teacher education programs to understand how students view the world around them to be able to best prepare them to teach with this global teaching perspective.…

This article describes the development, validation and application of a Rasch-based instrument, the Elementary School Science Classroom Environment Scale (ESSCES), for measuring students' perceptions of constructivist practices within the elementary science classroom. The instrument, designed to complement the Reformed Teaching Observation…

The purpose of this study was to test a hypothesized model that proposes a causal relationship between motivation and academic achievement on the acquisition of jazz theory knowledge. A reliability analysis of the latent variables ranged from 0.92 to 0.94. Confirmatory factor analyses of the motivation (standardized root mean square residual…
