Strong and Weak Metaphors for Limits
Oehrtman, Michael C. F.
International Group for the Psychology of Mathematics Education, Paper presented at the 27th International Group for the Psychology of Mathematics Education Conference Held Jointly with the 25th PME-NA Conference (Honolulu, HI, Jul 13-18, 2003), v3 p397-404
The metaphorical nature of first-year calculus students' reasoning about limit concepts is explored using an instrumentalist approach. Analysis of written and verbal language reveals that, while these students used motion terminology profusely when discussing limits, it was typically not intended to signify actual motion and did not play a significant role in their reasoning about limiting situations. In contrast, many of these students employed other non-standard metaphors, involving for example collapsing dimensions, to explore these situations and to build their emerging understanding of limit concepts.
