Early career teachers rarely receive sustained support for addressing issues of diversity and equity in their science teaching. This paper reports on design research to create a 30 hour professional development seminar focused on cultivating the interpretive power of early career teachers who teach science to students from historically non-dominant communities. Interpretive power refers to teachers' attunement to (a) students' diverse sense-making repertoires as intellectually generative in science and (b) expansive pedagogical practices that encourage, make visible, and intentionally build on students' ideas, experiences, and perspectives on scientific phenomena. The seminar sought to integrate student sense-making, scientific subject matter, teaching practice, and matters of equity and diversity on the same plane of professional inquiry by engaging participants in: (a) learning plant science; (b) analyzing classroom cases; (c) experimenting with expansive discourse practices in their classrooms; and (d) analyzing their classroom experiments in relation to student sense-making and expansive pedagogy. Twenty-eight teachers participated in two cycles of design research. An interview-based transcript analysis task captured shifts in teachers' interpretive power through their participation in the seminar. Findings showed that the teachers developed greater attunement to: complexity in students' scientific ideas; the intellectual generativity of students' sense-making; student talk as evidence of in-process, emergent thinking; and co-construction of meaning in classroom discussions. Findings also showed that participants developed deeper understanding of the functions of expansive teaching practices in fostering student sense-making in science and greater commitment to engaging in expansive practices in their classroom science discussions. # 2015 Wiley Periodicals, Inc.

In this study we explored how dramatic enactments of scientific phenomena and concepts mediate children's learning of scientific meanings along material, social, and representational dimensions. These drama activities were part of two integrated science‐literacy units, Matter and Forest, which we developed and implemented in six urban primary‐school (grades 1st–3rd) classrooms. We examine and discuss the possibilities and challenges that arise as children and teachers engaged in scientific knowing through such experiences. We use Halliday's (1978. Language as social semiotic: The social interpretation of language and meaning. Baltimore, MD: University Park Press) three metafunctions of communicative activity—ideational, interpersonal, and textual—to map out the place of the multimodal drama genre in elementary urban school science classrooms of young children. As the children talked, moved, gestured, and positioned themselves in space, they constructed and shared meanings with their peers and their teachers as they enacted their roles. Through their bodies they negotiated ambiguity and re‐articulated understandings, thus marking this embodied meaning making as a powerful way to engage with science. Furthermore, children's whole bodies became central, explicit tools used to accomplish the goal of representing this imaginary scientific world, as their teachers helped them differentiate it from the real world of the model they were enacting. Their bodies operated on multiple mediated levels: as material objects that moved through space, as social objects that negotiated classroom relationships and rules, and as metaphorical entities that stood for water molecules in different states of matter or for plants, animals, or non‐living entities in a forest food web. Children simultaneously negotiated meanings across all of these levels, and in doing so, acted out improvisational drama as they thought and talked science. © 2009 Wiley Periodicals, Inc.

Guided by sociological perspectives that view (young) children as agents who are shaped by and shape the structures of social systems in which they live, we studied forms that agency of young children from historically marginalized groups may take in science class when offered opportunities to engage in science in a variety of ways, how curricular and instructional structures facilitate or hinder these children's agency, and how their agency influence these structures. Using a case study approach, we analyzed performance and narrative data related to Carlos, a Latino 3rd grader, to understand the dialectical relationship between Carlos's agency and structural elements of his year-long science class as a sociocultural system populated with people, curricular and instructional structures, research structures, artifacts, and tools. Carlos performed and narrated his self in relation to science differently across the various structures in which he found himself-as a knowledge broker, a (self-appointed) authority, an emergent author, and a selfidentified scientist. His agency was linked to the roles he performed within the structures, roles he created at the intersection of the rules and resources that governed the structures in which he was immersed, and of his construction and interpretation of them. Learning from Carlos's case, we discuss implications for teachers of science to recognize the many ways in which students make meaning and plan for them, and to craft ideologies that embrace and nurture student agency in relation to structures-an essential understanding that should inform teaching and teacher education for justice and equity. # 2015 Wiley Periodicals, Inc.

In this research we put forth a theoretical framework that explores the nature and value of multi-modal narratives as a tool for studying young children's conceptions of themselves as scientists as they exist in relation to scientists out in the world. This framework shapes and is shaped by an empirical study that took place within the context of a year-long program that engaged children in integrated science-literacy experiences around two unitsone on matter and one on a forest ecosystem. Thirty-six children were asked twice to draw and discuss two pictures of times they were scientists. We present our findings in two main ways. First, we use case studies of three students (one each in the first, second, and third grade) to show how the various constructs in the theoretical framework come together in the empirical study, and to explore in depth the various ideas that the children revealed. Second, we share a summative descriptive analysis of the differences between the pre and the post interviews. One of the important findings included the increase in the number of pictures from the pre-interview to the post interview in which children represented themselves as scientists (31 to 61). The children also showed themselves and scientists out in the world as engaging in practices with a range of materials, for a variety of purposes, and with particular kinds of epistemological commitments.
