The authors argue that it is crucial to prepare early childhood teachers to create high-quality environments that facilitate the development of all children. The Early Childhood Ecology Scale-Revised (ECES-R) has been developed as a reflective tool to help early childhood teacher candidates examine their beliefs concerning classroom ecology. The authors posit that the ECES-R identifies five dimensions that promote a high-quality, culturally responsive classroom ecology. These dimensions include the sociocognitive, sociocultural, sociolinguistic, socioemotional, and sociophysical dimensions.
