Abstract

Proof of geometry is a difficult material for students. Various Skills are required to prove any theorems. The aim of study is indentify the ability of students in constructing the proof of geometry. This ekplorative qualitative research uses the subjects of Preservice elementary teacher at UIN SATU Tulungagung. A total of 35 students participated in this study and 3 research subjects were selected consisting of one subject for each type of response. The results showed that there were three types of responses found, namely empirical, rational, and formal types. The most type is the rational type and the least type is the formal type. The students with non-proof construction in the form of empirical argument to prove the premises are very tied to the image, and use the empirical facts to construction argument. Students with non-proof constructions of rational arguments prove with a formal evidentiary framework, yet they have not been able to reach the right conclusions. Students with fomal proof construction can perform a good formal proof. This shows that they have not been able to think formally perfectly. so that it takes a serious effort from the teacher to present the geometry proof material well.
