INVESTIGATION OF PRESERVICE MATHEMATICS TEACHERS’ PROOF SCHEMES ACCORDING TO DNR BASED INSTRUCTION

The aim of this study is to determine the types of the proof schemes used in the proof process by freshman and senior elementary pre-service mathematics teachers who are students at public university in 2011-2012 academic year and also to examine whether there is any difference between proof schemes...

Classification designed by Harel and Sowder (1998) is used.

Results indicated that all proof scheme types (external, analytical, empirical) are used by the students.
