Unfortunately the  Dr. Katherine Robinson’s talk, which was scheduled for Monday, December 1st, has been cancelled.  We are hoping to reschedule Dr. Robinson’s talk for January, so we will keep you posted regarding the details of that talk.  The next CACR meeting will be held on December 10th, with Lisa Fast giving an SPSS tutorial on how to manage large data sets.

“Detours in the Development of Mathematical Thinking”

Time: 1:00 p.m.  Place: Carleton University, VSIM 5220.

All are welcome. Dr. Bisanz is a very well-known researcher in the field of children’s mathematical development.

Abstract: The study of children’s mathematical thinking provides a valuable window on cognitive development during childhood, as well as insights into how to optimize the ways in which children learn mathematics. The common view is that learning mathematics is an incremental process in which older children develop new and more powerful concepts that incorporate or replace previous concepts. We have studied the development of two mathematical concepts in some detail: inversion, the principle that a + b – b must equal a; and equivalence, the concept that two sides of an equation must represent the same quantity. Contrary to the common view, many older children have considerable difficulty understanding or using these concepts in arithmetic despite the fact that preschool and early elementary school children appear to use these very concepts under certain conditions. These detours in development appear to be due to difficulties that children experience -and that we create–when we impose the symbol- based mathematical tools of our culture onto the informally acquired, intuitive mathematical knowledge of young children.

Deepthi Kamawar has volunteered her lab to provide snacks for this talk.

Please note that the next two CACR meetings will be held on Mondays instead of Wednesdays. On Monday, December 1 at 1:00 pm, Katherine Robinson will be an invited speaker. You can find information about her research online at:

Anyone wishing to provide snacks for this meeting should contact Nicole or Carla, or leave a comment here on the blog.

On December 10th, the CACR talks will return to their regular time of 1:00 on Wednesdays. Lisa Fast will be be providing an SPSS lesson. The topic will be “How to Effectively Manage Large Data Files in SPSS.”
