Pre-Service Mathematics Teachers' Concept Images of Radian
Akkoc, Hatice
International Journal of Mathematical Education in Science and Technology, v39 n7 p857-878 Oct 2008
This study investigates pre-service mathematics teachers' concept images of radian and possible sources of such images. A multiple-case study was conducted for this study. Forty-two pre-service mathematics teachers completed a questionnaire, which aims to assess their understanding of radian. Six of them were selected for individual interviews on the basis of theoretical sampling. The data indicated that participants' concept images of radian were dominated by their concept images of degree. As the data in this study suggested, pre-service mathematics teachers were reluctant to accept trigonometric functions with the inputs of real numbers but rather they use value in degrees. More interestingly, they have two distinct images of [pi]: [pi] as an angle in radian and [pi] as an irrational number. (Contains 8 figures, 7 tables and 1 note.)
