1. Epistemological Obstacles Related to Treating Logical Implications as Actions: The Case of Mary

Author

Anderson Norton, Rachel Arnold, Joseph Antonides, and Vladislav Kokushkin

Abstract

Understanding how students reason with logical implication is essential for supporting students' construction of increasingly powerful ways of reasoning in proofs-based mathematics courses. We report on the results of an NSF-funded case study with a mathematics major enrolled in an introductory proofs course. We investigate the epistemological obstacles that she experienced and how they might relate to her treatment of logical implications as actions. Evidence shows that an action conception may pose challenges when students transform or quantify implications and may contribute to erroneous assumptions of biconditionality. Our report on available ways of operating with logical implications as actions is a first step in designing instructional tasks that leverage students' existing reasoning skills to support their continued development.

3. Interprofessional Education (IPE) for Healthcare Students: How Does Teamwork Develop?

Author

Washburn, Dana H., Anderson, Caitlyn, and Schrader, Stephanie

Abstract

A recent interest in the improvement of teamwork in the healthcare industry has occurred as well as a realization that medical errors are often related to poorly functioning interprofessional teams. This interest is triggering changes in pre-professional accreditation standards for allied health programs which require the use of interprofessional education (IPE). A mixed-methods study using an experiential learning framework is underway to assess the effects of IPE clinical simulations on the development of teamwork skills and the extent to which this improves the understanding of teamwork among allied health students.

4. Offloading Cognitive Demands of Fractional Tasks on Working Memory through Drawings

Author

Stryker, Rachael, Kokushkin, Vladislav, Norton, Anderson, and Kerrigan, Sarah

Abstract

This study examined the role of student generated drawings to offload cognitive demands of a mathematical problem. We used Unit Transformation Graphs to compare students' thought processes when they had to solve the problem mentally, and when they were allowed to use pen and paper. The results indicated that the possibility to rely on drawings helped the participants to free up working memory resources and complete a cognitively demanding fractional task.

5. The Prime Number Theorem as a Mapping between Two Mathematical Worlds

Author

Norton, Anderson and Flanagan, Kyle

Abstract

This paper frames children's mathematics as mathematics. Specifically, it draws upon our knowledge of children's mathematics and applies it to understanding the prime number theorem. Elementary school arithmetic emphasizes two principal operations: addition and multiplication. Through their units coordination activity, children construct two mathematical worlds: an additive world and a multiplicative world. Understanding how children might map between their additive and multiplicative worlds provides insights into the prime number theorem. It also helps us appreciate the power of children's mathematics, constructed through the coordination of their own mental actions. [For the complete proceedings, see ED630210.]
