Internationally, standard observational measures of Early Childhood Education and Care (ECEC) are used to assess the quality of provision. They are applied as research tools but, significantly, also guide policy decisions, distribution of resources and public opinion. Considerable faith is placed in such measures, yet their validity, reliability…

Purpose: Language sample analysis (LSA) represents an ecologically valid method for diagnosing, identifying goals, and measuring progress in children with developmental language disorder (DLD). LSA is, however, time consuming. The purpose of this study was to determine the length of sample needed to obtain reliable LSA measures for children in…

This study aims to review the scientific papers on Early Childhood Education for Sustainability (ECEfS) published between 2008 and 2020 and reveal changes in the area. This systematic review was carried out in two stages. In the first stage, a systematic review of papers on ECEfS was conducted according to the specified criteria, and all…

The purpose of this research is to identify the situation through content analysis of scale development studies conducted by Turkish researchers in the field of preschool education. Thus, the overall trend of scale development research in preschool education was established. This research is a document analysis study. The documents studied are…

Large-scale education data are collected via complex sampling designs that incorporate clustering and unequal probability of selection. Multilevel models are often utilized to account for clustering effects. The probability weighted approach (PWA) has been frequently used to deal with the unequal probability of selection. In this study, we examine…

Many national and international educational data collection programs offer researchers opportunities to investigate contextual effects related to student performance. In those programs, schools are often used in the first-stage sampling process and students are randomly drawn from selected schools. However, the "incidental" dependence of…

Measurements of infants' quotidian experiences provide critical information about early development. However, the role of sampling methods in providing these measurements is rarely examined. Here we directly compare language input from hour-long video-recordings and daylong audio-recordings within the same group of 44 infants at 6 and 7 months. We…

This study is designed to reveal the research trends of graduate theses published in the field of computer programming in K-12 between 2018 and 2022. Document analysis was used for data collection in this study. The data was divided into 9 categories, and the results demonstrated that the scholars in the Departments of Computer Educational and…

The American School District Panel (ASDP) is the newest addition to the RAND Corporation's American Educator Panels (AEP), which are designed to survey panels of educators several times each year. RAND recruits AEP members using probabilistic sampling methods, which allow researchers to weight survey results to generalize to the national…

Secondary data analysis was employed to scrutinize factors affecting sample retention in a randomized evaluation of an early childhood intervention. Retention was measured by whether data were collected at 3 points over 2 years. The participants were diverse, immigrant, and U.S.-born families of color from urban, low-income communities. We…

Early childhood education and care (ECEC) remains a priority area for public policy, internationally and in Australia. However, an analysis of empirical research published internationally up to 2008 has identified a bias toward positivist methodologies within a "scientific/psychological' rather than educational perspective and with a focus on…

In this study, it is aimed to investigate the conducted researches in Turkey in the field of preschool science education in a comprehensive manner between the years 2016-2019. In this study, thematic content analysis method was used and the journals were examined which were indexed by DergiPark databases and published in social and human sciences.…

The main aim of this research is to display research trends in studies on augmented reality (AR) in teaching English as a foreign language by using bibliometric mapping and content analysis. For this purpose, 64 studies in total published up to 2019 were accessed for bibliometric analysis. In addition, 49 articles published between 2007 and 2019…

Complex surveys are often used to estimate causal effects regarding the effects of interventions or exposures of interest. Propensity scores (Rosenbaum & Rubin, 1983) have emerged as one popular and effective tool for causal inference in non-experimental studies, as they can help ensure that groups being compared are similar with respect to a…

Classroom engagement is important to young children's academic and social development. Accurate methods of capturing this behavior are needed to inform and evaluate intervention efforts. This study compared the accuracy of interval durations (i.e., 5 s, 10 s, 15 s, 20 s, 30 s, and 60 s) of momentary time sampling (MTS) in approximating the…
