The analysis of mathematical literacy in terms of geometric thinking of PGSD students

This study intends to analyze mathematical literacy on students of Elementary School Teacher Education/Pendidikan Guru Sekolah Dasar (PGSD) viewed from the level of geometric thinking and describe the mathematization process done by the students in solving geometry problems. It is a qualitative study involving eight sixth-semester students that had passed four mathematics courses. Data were gathered through documentation, essay test, and interview then analyzed using an interactive model. The results showed that students at the deductive level had correct, good, and complete conceptual and procedural knowledge. On the other hand, those at the informal-deductive level had correct but incomplete conceptual and procedural knowledge, and the students at the analysis and visualization level did not have adequate conceptual and procedural knowledge. The students at the deductive level were able to reason well from the mathematical problems they faced and demonstrate a coherent and reasonable geometric problem-solving process. However, these abilities were not found in students at deductive, analytical, and visual informal levels. This study concluded that the mathematical literacy possessed by the deductive-level students was more adequate to be used in solving geometry problems. Meanwhile, the students at the three previous levels; informal-deductive, analysis, and visualization, showed a gap in mathematical reasoning and an unorganized problem-solving process.
