The 0.70 and 0.80 reliability standards, proposed by Jum Nunnally, are widely employed across a spectrum of research domains. Nonetheless, due to their arbitrary nature, both standards fail to satisfy the needs of researchers. This paper presents a set of formulas that can be used to compute minimum reliability standards as a function of a…

To meet recent accountability mandates, school districts are implementing assessment frameworks to document teachers' effectiveness. Observational assessments play a key role in this process, albeit without compelling evidence of their psychometric rigor. Using a sample of kindergarten teachers, we employed Generalizability theory to investigate…

Despite research demonstrating the importance of language comprehension to later reading abilities, curriculum-based measures to assess language comprehension abilities in preschoolers remain lacking. The Assessment of Story Comprehension (ASC) features brief, child-relevant stories and a series of literal and inferential questions with a focus on…

Four rating scales for accessing aspects of early childhood education and care programs' quality were employed for the present study. The aim of the study was to examine scales' reliability by using them in one preschool and one infant/toddler classroom during the course of a week. Research results suggest that early childhood education and care…

The goal of this study is to develop a Guidance Qualification Scale for Preschool Teachers and examine the validity and reliability of the scale. The research was conducted with 374 teachers working in preschools in Istanbul and they were chosen by the random sampling method. Factor analysis was carried out for the construct validity of the scale.…

In accordance with the subject of this research, three different scales to measure preschool teachers' performances with respect to school principals', parents' and children's point of view were developed for the research. 51 principals, 893 parents and 256 children participated in the research. "Teacher Performance Evaluation…

The first aim of this study is to examine the validity and reliability of the Children's Playfulness Scale (CPS), which was developed to determine pre-school children's disposition towards play. The second aim is to test the effects of some variables on playfulness and whether such variables affect playfulness levels of children. About 196…

The aim of this study was to test reliabilities and validations for the Arabic translation of the Early Childhood Environment Rating Scale, Revised (ECERS-R) scale [Harms, T., Clifford, R. M., & Cryer, D. (1998). "Early childhood environment rating scale, revised edition." New York: Teachers College Press]. ECERS-R mean scores were…

Universal screening and progress monitoring measures are increasingly of interest to early interventionists who make decisions about the services provided to young children. A measure of infant-toddlers' growth in early movement, the "Early Movement Indicator" ("EMI"), was reported in 2002. However, the EMI has remained an…

Universal screening and progress monitoring measures are increasingly of interest to early interventionists who make decisions about the services provided to young children. A measure of infant-toddlers' growth in early movement, the "Early Movement Indicator (EMI)," was reported in 2002. However, the EMI has remained an experimental…

The study features two basic steps. The first step of the research aims to develop a scale to measure the attitude of preschool teachers towards the Persona Dolls Approach and to verify its validity/reliability through a general survey. The cohort employed in the research was drawn from a pool of preschool teachers working in and around the cities…

Use of the Classroom Assessment Scoring System (CLASS) is increasing across the United States as an important indicator of the quality of programs for young children. Professional development is required to facilitate teachers' understanding of the instructional behaviors upon which they will be judged. This study investigated the use of the…

Professional development of educators, especially in preschool years has been neglected in Iran. The purpose of this study was to investigate the viewpoints of experts and teachers about the purposes and content of the professional development plan for preschool teachers. This research is a descriptive-analytic study conducted through both…

Research Findings: This study explored the quality of teacher-child interactions within the context of a newly developed standardized task, Teacher-Child Structured Play Task (TC-SPT). A sample of 146 teachers and 345 children participated. Children who displayed the highest disruptive behaviors within each classroom were selected to participate.…
