Few studies have focused on understanding how teaching and learning in classrooms are mediated by other dimensions of the organizational systems of which education is an integral part. Our 7-year ethnographic study of an urban high school shows how time and temporality constitute key practical and theoretical resources to the actors in the…

The study examines how social and cultural factors mediate the teaching and learning of science in an Australian high school. Grade 10 students, many of them new migrants, often transient and from circumstances of economic hardship, were taught a 5-week unit on chemistry by a teacher with social and cultural histories similar to those of most of…

In this article, we explore the roles of student researchers as they have emerged over 5 years of studies on the teaching and learning of science in urban high schools. These studies incorporate sociocultural theory in an approach to research that explores the capital that urban students bring to school and situates student researchers as active…

I present theory and research associated with learning to teach science in inner city high schools on the east coast of the United States. I use theories from cultural sociology as a framework to explore how coteaching is enacted in a science teacher education program in which coteachers collaborate with high school students in cogenerative…

This study investigated whole class interactions in 200 science lessons involving 15 teachers and students from grades 8 to 12 in two urban Australian high schools. A relatively small number of 3-7 "target students" monopolized whole class interactions. In most instances target students were male. Compared to others in the class, target…

Over the past 7 years the authors have been involved in the development of a new model for the education of science teachers that has the potential to address teacher education in challenging urban settings characterized by problems such as teacher turnover and retention, low job satisfaction, and contradictions arising from cultural and ethnic…

In cultural historical activity theory, the entities that make a system are not conceived as independent but as aspects of mediated relations. Consequently, an individual, a tool, or a community cannot be theorized in an independent manner but must be understood in terms of the historically changing, mediated relations in which they are integral…

How do new teachers become confident and competent while they are interns in inner-city neighborhood schools challenged by many problems, often associated with economic shortfalls and cultural differences between the students and their teachers? Many science teacher education programs place a lot of emphasis on the planning stages of curriculum.…
