1 SYLLABUS Epistemological Foundations of Mathematics and Sciences: How does disciplinary knowledge develop and what are the implications for the design of instruction in math and science? Richard Lehrer, Peabody College, and Keivan Stassun, College of Arts and Sciences Mondays, 1:10-4:00, WC 101 Overview Epistemological Foundations of Mathematics and Sciences examines the social, cognitive, and material arrangements and mechanisms that contribute to how we know what we know in mathematics and in sciences. Knowing how we know is the domain of epistemology, and assembling the means to create disciplinary-distinct ways of knowing creates what Knorr Cetina (1999) calls an epistemic culture. It is this culture within a discipline that sustains and regulates core assumptions about knowing within that discipline. The focus on epistemology is intended as counterpoint to more traditional approaches to education, which take the content to be taught as fixed and the aim of pedagogy as being to develop effective methods (e.g., “best practices”) for delivery of this knowledge. Epistemological Foundations of Mathematics and Sciences focuses instead on considering what makes knowing challenging in these disciplines, because such a perspective offers alternative framings of the problem of teaching. Questions about teaching science—what should be taught, to whom, and when—are all potentially revised by considering carefully how we come to know. How well do current instructional designs help students understand the nature of knowing in sciences and in mathematics? How might alternative instructional designs be informed by analysis of forms of knowledge and ways of knowing (i.e., practices) in math and science? Although epistemology is traditionally the province of philosophy, we aim to adopt a developmental perspective. A developmental perspective traces the influence of earlier forms of knowledge making on later forms, and it orients analysis to the history and progression of ideas. History and progression occur at different scales, and we propose to examine two senses of development. The first is historic, with a scale measured in decades, perhaps centuries. Accordingly, one strand of the course will trace the trajectory of important ideas in the disciplines, such as force, field, or experiment, across social and historic contexts. For example, although experiment now enjoys an unquestioned status in the sciences, historically it was hotly contested, primarily because it involved rearrangement and disruption of everyday observation, along with attendant uncertainties about the machines employed and related material circumstances of observation (Gooding, 1990; Shapin and Schaffer, 1985). Experiment also demanded a change in rhetoric: The research article, a form so familiar to us that it appears to have the status of a naturally occurring event, was the product of a radical shift in written communication 2 introduced by Newton (Bazerman, 1988). To complement historic analysis, we will also consider learning and developmental transitions in how individuals come to understand disciplinary practices, such as experiment, or how concepts are generated and transformed by individuals. These studies of individual learning are often conducted in settings designed to support conceptual change, with explicit attention to reconfiguring learning environments so that the grounds for knowing—such as proof and proving in mathematics, or experiment in science—are made more accessible to participants. By participating in classrooms structured in this way, students presumably are in a position to know how scientists and mathematicians generate knowledge. We will critically examine this emerging literature and seek to contribute toward its further progress. References Bazerman, C. (1988). Shaping written knowledge.

This course does not follow that mold. Instead, instructors suggest resources and prospective directions, but we expect that the path taken will emerge from the collective activity and interests of the participants. We are asking each participant to lead one class session. The leader suggests readings, posts readings on OAK and generates at least one question to guide further discussion. We propose to meet weekly to discuss readings and will employ OAK to post readings, questions for discussion, and threads of conversation before convening the face-to-face interaction of the seminar. Each participant is responsible for generating and posting one response to the reading that can prospectively be elaborated during class discussion. Each participant will formulate an approach toward pedagogy for an important/puzzling epistemic idea in math or science. The approach should be informed by analysis of the history of the idea and by what is known (or could in principle be found out through research) about how students in math/science classes typically think about that idea. The goal is to use epistemic analysis to design which knowledge is to be taught, rather than taking it as given by textbooks and other authorities. Participants may work in 3 interdisciplinary teams (but this is not required). The particular form of each project is determined by the question. Some may wish to design instruction, others may wish to investigate more closely the history of a particular practice or idea. We will engage distinguished scholars in the field to speak about their work in this area. The talk will be aimed at a general audience that we anticipate will span Peabody College and the College of Arts and Sciences. Each speaker-scholar will also consult with participants in the seminar on their projects described above. o Professor Andrea diSessa is a learning scientist at the University of California-Berkeley. His work includes careful attention to the nature of knowledge and especially to relations between everyday and scientific knowledge in the design of learning environments. o Associate Professor David Cohen, of the Physics and Astronomy Department at Swarthmore College, is a practicing astronomer with an interest in the history of science. We expect that Professor Cohen will provide a working scientist’s view of prospective relations between pedagogy and epistemology. o Assistant Professor Dahlia Porter, Vanderbilt Department of English, studies the historical development of scientific narratives including the earliest written descriptions of experimentation and the role of analogy in scientific narratives. o Assistant Professor Ole Molvig, Vanderbilt Department of History and Department of Physics & Astronomy. o Professor Nancy Nercessian is a cognitive scientist at the Georgia Institute of Technology. Her work focuses on historic and cognitive analysis of model-based reasoning in the sciences. Each week, we anticipate devoting about half of the class time to discussion of reading and about half to collaborative work aimed at developing an epistemic project.
