Influences of Teacher–Child Social Interactions on English Language Development in a Head Start Classroom

Increasing numbers of Spanish-speaking preschool children require attention to improve the likelihood of success in school. This study, part of a larger 2-year ethnographic study of a Head Start classroom, elaborates the role of teachers’ interactions with students who were learning English. Using an interactional ethnography approach, the authors focus on the social nature of these interactions. The study illuminates the kinds of teacher interactions with students that support and hinder the students’ language learning. It reinforces the importance of student engagement in social interactions with teachers and with English other than codes of obedience and authority. Finally, it recommends actions teachers can take to provide optimal circumstances for English learning interactions for students.

Autonomy: The importance of a scientific theory in education reform

The six national goals established by the National Governors' Association for education reform in the 1990s were conceived by people who had the power to decide what outcomes they wanted based on their own values and priorities. Although it is impossible to avoid questions of values, it is necessary in defining goals for education to consider scientific, explanatory theories about how human beings acquire knowledge and moral values. Jean Piaget's conceptualization of autonomy, in his unusual sense of the term, provides an overall aim for the development of individuals as well as of society, both in the intellectual and the moral realms. Autonomy as the aim of education is based on constructivism, a scientific theory, and would obviate the outdated conceptualization and contradictions among the six national goals.
