Designing a Hypothetical Learning Trajectory Using Prezi Presentation and GeoGebra Application on Flat-Shaped Triangle Geometry Materials


Technology plays a crucial role in enhancing the quality of math learning. In addition to adapting to the rapid advancement of ICT, technology serves as a visualization aid for abstract mathematical concepts, facilitating understanding. Prezi presentations and GeoGebra application are technological tools that can be used as a medium for learning math. Prezi Presentation is used as a presentation medium, while GeoGebra functions as a dynamic tool to enhance the understanding of geometry. They both positively impact the development of mathematical thinking, facilitate meaningful learning experiences, and can be used as alternatives in designing a hypothetical learning trajectory for concepts related to triangle types. This study aims to design a Hypothetical Learning Trajectory (HLT) using Prezi presentation and GeoGebra for the material related to triangle types. The HLT tailored to suit the characteristics of students, making it easier to construct independent understanding related to triangle types through the use of dynamic technology such as Prezi and GeoGebra. This study uses a design research approach consisting of three phases: introduction, design experiments, and retrospective analysis. This was carried out solely in the preliminary phase to develop the initial prototype of the HLT focusing on the concept of triangle types. The HLT will be further examined in subsequent research and retrospectively analyzed to develop the Learning Instructional Theory (LIT) as the final product.
