Research and Development Experience

Strengthening Tomorrow's Education in Measurement I and II [STEM]  
PI: Dr. Jack Smith (MSU)  

NSF-funded project examining the capacity of K – 6 curricula to provide opportunities for the robust learning of spatial measurement and engage pre- and in-service teachers in professional development in spatial measurement.

ICME-12 Survey Team: The relationship between research and curriculum design  
Chair: Dr. Glenda Lappan  

Presently collecting and analyzing survey data from U.S. representative states and over six countries to prepare for an ICME-12 presentation investigating the relationship between research and curriculum design

Reasoning-and-Proving in High School Geometry Textbooks  
Michigan State University College of Natural Sciences-funded graduate student composed project that investigated the opportunities for reasoning-and-proving in seven high school geometry textbooks.
Mathematics Discourse in Secondary Classrooms [M-DISC]  
PIs: Dr. Beth-Herbel-Eisenmann (MSU), Dr. Michael Steele (MSU), & Dr. Michelle Cirillo (University of Delaware)  

NSF-funded project to develop practice-based professional development materials focused on promoting rich mathematical classroom discourse.

MDISC Website

Discourse Analysis: A Catalyst for Reflective Inquiry in Discourse in Mathematics Classrooms [CRIMC]  
PI: Dr. Beth-Herbel-Eisenmann (MSU)  
NSF-funded project studying the nature of discourse in mathematics classrooms and the process of teachers engaged in practitioner research.
PIs: Dr. Sandra Crespo & Dr. Vince Melfi (MSU)  
Project investigating students who have watched the Cyberchase television program solving complex mathematical tasks. I participated in data collection at one school site, which included doing two activities with three groups of students and coding their responses.
ICME-11 DG: The evaluation of mathematics teachers and curricula in educational systems  
Chairs: Dr. Glenda Lappan & Dr.  Barbara Clarke  

Helped to collect papers, organize session, and take notes during discussion group sessions to inform future sessions and writing of summary
