NOMAD 9(3), 2004. Open ended problem solving in geometry revisited

 

HANS ERIK BORGERSEN

Abstract
This article is a successor to Borgersen’s (1994) study of a project on cooperative problem solving in small groups, organized as part of a geometry course at the college level. It focuses on the effects of a gradual change of the project. This report studies the transition of the project from 1994 to 1996 (Borgersen 1995, 1997, 1999) as the course changed from being a medium size course for about thirty students from the same study program to become a large course for nearly one hundred students from three different study programs.

Sammendrag
Denne artikkelen er en videreføring av Borgersens (1994) undersøkelse av et problemløsnings
prosjekt, basert på samarbeid i smågrupper og organisert som del av et geometrikurs på universitet/høgskolenivå. Artikkelen fokuserer på effekten av en gradvis endring av prosjektet. Den undersøker prosjektene fra 1994 til 1996 (Borgersen 1995, 1997, 1999), idet geometrikurset endret seg fra å være et middels stort kurs med omlag tretti studenter fra samme studieprogram til å bli et stort kurs med nær ett hundre studenter fra tre ulike studieprogram.
