13. Dissertation Project: Sean Larsen Mathematics TITLE: Supporting the Guided Reinvention of the Concepts of Group and Group Isomorphism: An Evolving Local Instruction Theory ABSTRACT: In this talk I will describe a local instruction theory that emerged over the course of a sequence of three teaching experiments in elementary group theory. Each of the experimental "classrooms" consisted of two university students and the teacher/ researcher. These teaching experiments were guided by the instructional design theory of Realistic Mathematics Education (RME). The goal was to promote the guided reinvention of the concepts of group and group isomorphism. The local instruction theory consists of a sequence of instructional activities and a justification (theoretical and empirical) for the sequence. The concepts of group and group isomorphism are seen as first emerging as models of students’ informal mathematical activity and then evolving into models for more formal mathematical reasoning. This process was driven by the students’ participation in classroom mathematical practices. The individual students’ mathematical development is seen as reflexively related to their participation in these mathematical practices.

14. Dissertation Project: Sally Jacobs C & I TITLE: Advanced Placement BC Calculus Students’ Ways of Thinking About Variable ABSTRACT: The dissertation was an exploratory study investigating calculus students’ notions about the concept of variable in the contexts of function, limit and derivative. The findings indicate that students think about variable in qualitatively different ways, depending on whether they have a calculational versus conceptual orientation to the mathematical task at hand. Also, in the context of limit and derivative, their conceptions of variable are somewhat less flexible. Finally, a Variable Conceptions Framework for analyzing student conceptions of variable is proposed.
