Kemampuan Spasial Siswa SMP melalui ELPSA Framework

Abstract

Spatial ability is essential in learning geometry, as it involves visual interpretation. To understand geometric relationships and properties, students need to develop their spatial skills. However, many students struggle with low spatial abilities, especially in constructing and visualizing geometric shapes. One reason for this is that students are rarely required to think critically about geometric transformations; instead, they often rely on rote learning and calculations. The ELPSA framework, which emphasizes active learning, is proposed as a way to enhance spatial abilities. This study aims to: 1) assess students' spatial abilities through the online ELPSA framework, and 2) describe their spatial profiles. The research involved 15 eighth-grade students at Banda Aceh, using a mixed-methods approach with sequential explanatory design. The subjects included four students with varying levels of spatial ability: high, medium, and low. The research instruments were spatial ability tests for quantitative data and interview guidelines for qualitative data. Quantitative data were analyzed using descriptive statistics, while qualitative data underwent data reduction, presentation, and conclusion drawing. Results showed that 62.22% of students demonstrated good spatial abilities. High-ability students excelled in at least two spatial indicators, indicating strong skills. Medium-ability students struggled to represent geometric shapes, and low-ability students showed poor spatial skills overall
