Abstract

Facing the current digital era, correct and accurate decisions are needed to deal with the problems. This research aimed to explore the decision-making abilities of prospective mathematics teacher students in solving geometric proof problems. This research was a qualitative descriptive study with research subjects 3 out of 32 students of the 2nd semester Mathematics Education study program. The research instrument is the researcher himself, who is assisted with geometric proof problem tests and interview guidelines. Data analysis was including reduction, presentation, and conclusion. The validity of the research data was tested using methods triangulation. The research results show that subjects with a proof ability of K2 can build and clarify geometric concepts/principles and can assess the reasonableness of ideas even though the subject feels unsure about their choice. Subjects with a proof ability of K3 can build and clarify geometric concept/principle ideas but cannot assess the reasonableness of proof ideas. Subjects with a proof ability of K4 can build ideas of geometric concepts/principles, can clarify even though they are incomplete, and cannot assess the reasonableness of proof ideas. Students need to be equipped with decision-making skills in solving proof problems as preparation to become mathematics teachers in the future.

Abstract

When solving problems, the spontaneous actions of students identified as slow learners (SL) often reflect their cognitive limitations. This study analyzed students' SL understanding of mathematical concepts through representational gestures as a means of communication in constructing concepts. A qualitative case study was conducted in a public junior high school in Lamongan Regency. From eight SL students identified through IQ tests and teacher interviews, only three consistently used representational gestures and were selected as the subjects. Although limited, this sample enabled an in-depth analysis while acknowledging restricted generalization. Data were collected through functional tasks, gesture observations, and interviews and were then analyzed interactively through data reduction, display, and conclusion drawing. The results showed that SL students frequently used hand gestures to represent graph axes or intersection points but misinterpreted variable relationships. They could only classify objects based on conceptual conditions, while other indicators of understanding were not attained. These findings suggest that teachers should consider students’ gestures not only as spontaneous expressions but also as diagnostic cues for misconceptions and as a support for mathematical communication.
