Abstract

Students with a rigor level of geometric thinking can analytically solve problems, yet the ability may not be readily observable. Thus, an example of how students solve problems merits explorations. Inspired by students problem solving, this study aimed to examine the students anticipatory profile in determining Papaya tree roots' dimensions. This qualitative research utilized tests and interview. Two tests were carried out: van Hiele geometric level grouping test for selecting the research participants and the report-based test for the actual project. Seventeen students took the van Hiele test, and one of them, who achieved the rigor level, was selected for the interview. Data obtained from the interview were then analyzed qualitatively. The study showed that students with a rigor level of geometric thinking anticipated analytically. The subject was able to explain a geometric problem systematically, starting from analyzing problems, clarifying detailss, to presenting arguments clearly and precisely. The findings in this study generate useful information for teachers who train their students to analyze a geometric problem correctly and adequately.

Abstract

This study examined the level of students' logical thinking ability and the level of students' understanding in geometry, and also the relationship between the students' level of logical thinking and students' level of understanding in geometry. The tests of logical thinking and geometry concept development level were administered to 387 students of the third year science classes selected from 10 State Senior High Schools in Jember, East Java. The results indicated that 8.01%, 24.81%, 29.97%, 37.21% students were respectively at concrete, transition, early formal, and formal levels; and 14.47%, 31.52%, 40.05%, 13.44%, 0.52%, 0% were at previsualization, visualization, analysis, informal deduction, deduction, and rigor respectively. There was a significant relationship between students' level of logical thinking ability and their level of understanding in geometry
