Research Findings: In this study, we tested whether it is possible to reliably evaluate the quality of interactions between early childhood educators and children using a thin-slice coding approach. Ninety-seven early childhood educators were videotaped for two five-minute intervals: one mealtime observation and one standardized activity. Videos…

This paper introduces the LIDO, or the Low-Inference Discourse Observation tool, that captures discourse moves produced by students and teachers in whole-classroom discussions. Coding methods are described, followed by analyses that explore validity of the LIDO through correlations among LIDO-coded discourse moves and between LIDO scores and…

The objective of this paper is to present the conception and validation of the Quality of Educators' Observation and Planning Practices Scale (QEOPPS). The instrument assesses the quality of early childhood educators' observation practices (observing children, collecting information, using the collected information, paying attention to each child)…

Background & Context: Early childhood contexts characterized by high-quality adult-child interactions have important consequences for children's development (Hamre, 2014; Peisner-Feinberg et al., 2001). The use of classroom observation tools to measure the quality of such interactions in early education and care (EEC) settings has become…

Through two studies, this work examined the applicability, interpretability, and construct validity of the Classroom Assessment Scoring System K-3 (CLASS) to measure quality of classroom interactions. In the first study, the CLASS was used in 332 classrooms to test three alternative models (in time order, the one-, three-factor, and two-factor…

Research Findings: The purpose of this study was to refine and validate the Assessing Classroom Sociocultural Equity Scale (ACSES), an observation tool for measuring equitable sociocultural interactions in early childhood classrooms (pre-K to Grade 3) with racially minoritized learners (RMLs). Preliminary psychometric information from 142…

In 2017, the Office of Planning, Research, and Evaluation (OPRE) in the Administration for Children and Families (ACF) funded Mathematica to conduct the Infant and Toddler Teacher and Caregiver Competencies (ITTCC) project. The project aims to examine existing efforts across states, institutions of higher education, professional organizations, and…

Measures of teaching are used internationally to understand and improve quality in early education with little consideration for ecological validity. In this study, we analyze videos gathered in 58 K-1 classrooms in Central Mexico to evaluate the validity and reliability of scores from an observational tool developed in the U.S. and used…
