The findings reported on in this manuscript emerged from a design experiment conducted at a low‐income urban middle school intended to support the teacher in incorporating pedagogical practices supportive of students' everyday knowledge and practices during a 6th grade unit on food and nutrition from the LiFE curriculum. In studying the impact of the design experiment we noticed qualitative shifts in classroom Discourse marked by a changing role and understandings of the funds of knowledge students brought to science learning. Using qualitative data and grounded theory we present an analysis of the different types of funds of knowledge and Discourse that students brought into science class. We focus on how the students' strategic use of these funds augmented the learning experience of the students and the learning community as well as the learning outcomes. We discuss the implications these funds of knowledge and Discourses had on the development of three related third space transformations: physical, political, and pedagogical. © 2008 Wiley Periodicals, Inc.

This article investigates the development of agency in science among low-income urban youth aged 10 to 14 as they participated in a voluntary year-round program on green energy technologies conducted at a local community club in a midwestern city. Focusing on how youth engaged a summer unit on understanding and modeling the relationship between energy use and the health of the urban environment, we use ethnographic data to discuss how the youth asserted themselves as community science experts in ways that took up and broke down the contradictory roles of being a producer and a critic of science/education. Our findings suggest that youth actively appropriate project activities and tools in order to challenge the types of roles and student voice traditionally available to students in the classroom.

The underrepresentation of non-White students and girls in STEM fields is an ongoing problem that is well documented. In K-12 science education, girls, and especially non-White girls, often do not identify with science regardless of test scores. In this study, we examine the narrated and embodied identitiesin-practice of non-White, middle school girls who articulate future career goals in STEM-related fields. For these girls who desire an STEM-related career, we examine the relationships between their narrated and embodied identities-in-practice. Drawing on interview and ethnographic data in both school and after school science contexts, we examine how STEM-career minded middle school girls articulate and negotiate a path for themselves through their narratives and actions. We present four types of relationships between girls' narrated and embodied identities-in-practice, each with a representative case study: (1) partial overlaps, (2) significant overlaps, (3) contrasting, and (4) transformative. The implications of these relationships with regard to both hurdles and support structures that are needed to equip and empower girls in pursuit of their STEM trajectories are discussed. #

The middle grades are a crucial time for girls in making decisions about how or if they want to follow science trajectories. In this article, the authors report on how urban middle school girls enact meaningful strategies of engagement in science class in their efforts to merge their social worlds with the worlds of school science and on the unsanctioned resources and identities they take up to do so. The authors argue that such merging science practices are generative both in terms of how they develop over time and in how they impact the science learning community of practice. They discuss the implications these findings have for current policy and practice surrounding gender equity in science education.

Current discourses of equity in teaching and learning are framed around calls for inclusion, grounded in the extension of a set of static rights for high-quality learning opportunities for all students. This essay presents a rightful presence framework to guide the study of teaching and learning in justice-oriented ways. This framework highlights the limitations of equity as inclusion, which does not adequately address the ways in which systemic injustices manifest in local classroom practice. Rightful presence orients the field towards the importance of political struggles to make present the lives of those made missing by schooling and discipline-specific norms. Three tenets for guiding the use of this framework in teaching and learning are offered. Two contrasting vignettes from STEM classrooms illustrate tenets and emergent tensions.
