Abstract

This research is a descriptive study that aims to describe the mathematical abstraction type conjecture in triangle and square. The subjects in this research were 3 Grade VIII students of Junior High School. This study was a design research which consisted of preliminary design, focus group discussion, trial, interview, and retrospective analysis. The data collection techniques used were test with problem solving type and interviews. Test data and interview data were analyzed by using qualitative descriptive methods, by telling everything that was obtained both from student answers and from interviews. From the results of data analysis, it was concluded that all students understood the problem. However, understanding the problem does not guarantee that students can put forward and propose conjectures. Even though the conjecture has the possibility of being true and of being false, good conjecture must be supported by the underlying theories and concepts. Students who do not have basic concepts are often unable to make conjectures and prove these conjectures, thus it can be concluded that students’ ability to make conjectures is influenced by their previous knowledge. The stages in making conjecture consists of understanding the problem, exploring the problem, formulating conjecture, justifying conjecture, and proving conjecture.
