This dissertation sheds light on conceptual change dynamics in a knowledge-building classroom to better understand the complex ways students' reasoning and ideas shift in conversation with other members in the classroom. Specifically, this dissertation attempts to characterize the contextual considerations that result in students converging to…

This study investigated science classroom discourse in terms of the types of teacher discursive moves (TDMs) and the relationships between the types of TDMs and student-led cognitive contributions in different science concepts by considering the classroom context. An experienced seventh-grade science teacher and her 19 students were engaged in…

This paper is based on an exploration of communication and argumentation in urban science classrooms, and provides a description of the role that Hip-hop based education plays in supporting these major components of science education. The paper is intended to both support, and critique conventional uses of hip-hop based education, and provide…

We set out to understand how different instantiations of inquiry emerged in two different years of one elementary teacher's classroom. Longitudinal observations from Mrs. Charles' 5th grade science classroom forced us to carefully and deliberately consider who exactly was responsible for the change in the class activities and norms. We provide…

In this study I rely on sociocultural views of learning and teaching to describe how fifth- sixth-grade students in a Fostering a Community of Learners (FCL) classroom gradually adopted scientific ideas and language in a socially complex classroom. Students practiced talking science together, using everyday, scientific, and hybrid discourses as…

Examines how lower-track science students understand shifts in standard classroom discourse patterns. Finds that students insert struggles for social status into classroom arguments about scientific ideas, making it difficult to separate in a group discussion whether evidence or the social politics of the class convinces students to accept an…
