The paper proposes new measures of difficulty and discriminating values of binary items and test consisting of such items and find their relationships including estimation of test error variance and thereby the test reliability, as per definition using cosine similarities. The measures use entire data. Difficulty value of test and item is defined…

The aim of this study is to develop a valid and reliable measurement tool that can be used to measure the level of school principals' micromanagement behavior. After a comprehensive literature review, a candidate item pool with 52 items was created. While writing the items, micro-manager behaviors defined in the literature were adapted to school…

In this study, the adaptation of the "Digital Competence for Educators" self-assessment instrument developed by the European Commission Joint Research Centre to Turkish culture and the validity and reliability study of the Turkish form were carried out. The study was conducted with 697 teachers working in different provinces of Turkey.…

The competences expected from teachers are described in several international reports. An investigation of teacher competences has a potential to analyze and delineate the current situation. Assessment of any construct necessitates utilization of appropriate scales with established validity and reliability. Currently available validated digital…

Teachers' digital competence is very significant in terms of integrating digital technologies into the education process. This study aims to develop an up-to-date scale that can determine the digital competencies required for teachers to acquire new skills that arise with the change and development of technology and use them in educational…

Minority stress theory is a model for understanding health disparities among sexual minorities, defined as those who experience a level of same-sex attraction, identity, or behavior. Methods for assessing minority stress among youth included only adult measures until the development of the Sexual Minority Adolescent Stress Inventory (SMASI). The…

We compared coefficient alpha with five alternatives (omega total, omega RT, omega h, GLB, and coefficient H) in two simulation studies. Results showed for unidimensional scales, (a) all indices except omega h performed similarly well for most conditions; (b) alpha is still good; (c) GLB and coefficient H overestimated reliability with small…

Purpose: The study begins by defining and conceptualizing Transformative Leadership Conversation (TLC). The conceptualization addresses the meaning of transformation, sensemaking and learning dialogue, and the conversation structures of framing, questioning and listening, and affirming. Next, the authors build a theoretical argument from…

Motor competence as an indicator of gross motor development is characterized by changes in movement patterns and outcomes. The Test of Gross Motor Development-3 consists of six locomotor and seven ball tasks used to assess the quality of fundamental motor skills in children. The purpose of this study is twofold--to produce a Slovenian translation…

We reviewed 19 English version scholarly works and 11 other language translation articles from 2004-2018 for the Center for Epidemiologic Studies Depression Scale -- Revised (CESD-R). Alpha was 0.92 (0.90, 0.94; N = 13,150); convergent, factorial, and diagnostic validity were robust. Implications for counseling practice and research were discussed.

The main purpose of this research is to develop a measure to determine university students' perceptions of the flipped learning model. Exploratory and confirmatory factor analysis were conducted within the scope of the validity study of the scale, and its internal consistency was analyzed for its reliability. The data for exploratory factor…

In the last 30 years, 4 distinct theoretical approaches have been described for early childhood science education. The approaches are, empiricist, Piagetian, socio-cognitive and socio-cultural. Drawing on the differences among these approaches regarding the theoretical framework adopted in teaching, the role that is assigned to the teacher during…

Few instruments screen for autism spectrum disorder (ASD) among kindergarteners and older children. The Autism Screen for Kids and Youth (ASKY) is a 30-item parental questionnaire for 4- to 18-year-old children and adolescents available in Arabic, English, and Hebrew. We examined the sensitivity, specificity, and temporal stability of the Hebrew…

This article was stimulated by a review of instruments assessing creative and innovative social environments seventeen years ago. This stands alone as the only published, comprehensive, comparative review of multiple instruments aimed at this conceptual space. Although this review provided an important contribution to the literature, there are a…

This study aimed to create and validate a scale for early childhood educators that reflects the cultural sensitivity of educators in classrooms. We collected data from 403 early childhood educators in Adiyaman, Turkey. Experts' assessments were consulted for content validity, and EFA and CFA were done for the reliability and validity of the scale.…
