Abstract

Descriptive Geometry is a fundamental course that demands high-level spatial visualization skills, where students often face significant cognitive challenges in projecting three-dimensional (3D) objects onto two-dimensional (2D) planes using conventional methods. This study aims to deeply explore student perceptions regarding the use of the dynamic geometry software GeoGebra as a medium for visualizing abstract concepts in this course. Using a qualitative case study approach, this research involved 13 students from the mathematics education program at Universitas Negeri Jakarta. Data were collected through semi-structured interviews and analyzed using thematic analysis. The findings indicate that students perceive GeoGebra as a transformative pedagogical tool. Four main themes were identified: (1) GeoGebra serves as a conceptual bridge that translates abstract concepts into concrete and dynamic visual representations; (2) GeoGebra's interactive environment is considered far superior to the static paper-and-pencil method, offering accuracy, efficiency, and freedom to experiment; (3) The use of GeoGebra shifts the student's role from a passive recipient to an active learner engaged in independent exploration; and (4) Despite an initial learning curve, the challenge of mastering the software fosters the development of student agency and learning autonomy. This study concludes that GeoGebra effectively reduces the cognitive load associated with spatial visualization and enhances student engagement and conceptual understanding. The implications of these findings underscore the importance of planned technological integration into advanced geometry curricula to facilitate more meaningful learning.

Abstract

The change from PMM (Merdeka Mengajar Platform) to Ruang GTK requires further study investigating how the Ruang GTK is utilised compared to PMM. The present qualitative study aims to describe the experiences of 15 mathematics teachers (13 teachers and two vice principals) in using Ruang GTK compared to their previous experiences using PMM. The study spanned six weeks and was conducted online and offline. The data were collected through interviews and audiovisual materials, with interview guidelines developed based on an adaptation of the Technology Acceptance Model (TAM3) constructs: perceived usefulness, perceived ease of use, job relevance, voluntariness, and use. The data underwent a three-stage analysis process, encompassing data condensation, data presentation, verification, and conclusion drawing. The results showed that more and more participants rarely use Ruang GTK due to motivational factors, changes in the curriculum, and the need to attend many offline trainings. The discrepancy in the advantages accruing from utilizing Ruang GTK compared to PMM can be attributed to the substantial diminution in teacher workload. Ruang GTK is easier to operate, especially because it eliminates features that confuse teachers. Lastly, many of the participants now access the Ruang GTK only when there is an obligation or demand from their superiors, and only a few

Abstract

Conventional descriptive geometry instruction often fails to facilitate accurate spatial visualization, perpetuating epistemological obstacles. This study investigates how integrating independent exploration via GeoGebra impacts students' knowledge construction of orthogonal projection concepts. A descriptive qualitative case study was conducted involving 16 mathematics education students at the State University of Jakarta during the odd semester of 2026. Data were collected using a conceptual understanding test comprising three hierarchical questions and a structured interview guide, and then analyzed through an interactive qualitative model. Findings indicate that GeoGebra functions beyond a mere visual aid; it acts as a cognitive instrument mediating instrumental genesis. Specifically, independent exploration utilizing dragging and 3D manipulation empowered students to diagnose and dismantle persistent epistemological obstacles related to dimensional transformations and planar intersections. However, varying levels of student dependence on instructor scaffolding highlight that successful instrument adaptation relies on individual learning dispositions. The study implies that effectively integrating technology in geometry education requires a differentiated pedagogical approach and a shift toward orchestrated digital exploration.
