Abstract	Written scientific argumentation is a common practice among scientists, yet it is relatively absent from science K-12 classrooms (Applebee & Langer, 2013). However, recent research shows that opportunities to engage in collaborative discourse and argumentation provide students enhanced conceptual understanding and reasoning. Since one of the hallmarks of doing science is learning critical and rational skepticism, opportunities to develop the ability to argue scientifically appear to be an essential feature of a successful classroom (Osborne, 2010). What does this approach look like in a high school science classroom? How do students respond to and take up such practices in their talk and writing? This dissertation examines how high school students learn to construct and evaluate evidence as well as "do" science during an ecology unit in an accelerated biology class taught by a highly regarded teacher. The teacher's approach was grounded in the assumption that students learn through modeling to understand scientific content knowledge and practices while engaging in inquiry. Specifically, this study explored how the teacher supported her students using talk, writing, and arguing to learn for reflective analysis during an ecology unit. This specific unit required the construction of mathematical charts and graphs to better understand a multi-day lab demonstration project on interspecific and intraspecific competition among two species of "Paramecia." Teaching and learning of scientific argumentation are framed as a construction of academic literacies (Lea & Street, 1998), that are an emphasis on describing the literacy practices within disciplinary fields (biology) and how those literacy practices might be acquired. So conceptualized, researching the acquisition and development of academic literacies focus on describing how students are socialized into the community's practices including its literacy practices. Research methodology was grounded in microethnographic discourse analysis of intercontextuality, intertextuality, epistemic levels of evidence construction, conversation functions in classroom discourse, and argumentative move analysis. Data included classroom discourse and students' informal descriptive and comparative writing, as well as formal argumentative writing. Students' writing was examined for connections to classroom events (intercontextuality), to graphs and previous written work (intertextuality), for epistemic levels of evidence construction, and argumentative moves. This work builds on previous studies of teaching and learning scientific argumentation that considered the epistemic practices in scientific argumentation (Kelly & Takao, 2002; Manz, 2012; Manz, 2015). Using epistemic levels of evidence construction, I examined how the teacher facilitated conversations about making scientific arguments and constructing evidence in increased levels of abstraction from noticings and public attributes to making experimental claims and facts (Manz & Renga, 2017). Students developed their argumentative writing through practicing claims, incorporating more epistemic levels of evidence construction over time, and toward the end of the project warranting their evidence. Theoretically, this dissertation supports and extends the uses of an academic literacies and social construction lenses to understand the complexities of teaching epistemic practices of evidence construction in classroom discussions and students' using the same practices in their writing. An academic literacies framework has the possibility of making science classrooms more equitable learning environments through dialogic learning processes.
