MathExplorers is an innovation in mathematics learning that integrates AR technology to help students, especially in class VII SMP, understand geometric shapes in a more interactive and fun way. With 3D visualization features, practice questions, interactive simulations and educational games, this application offers a more in-depth and effective learning experience. MathExplorers is not just a learning app, but also a tool that can help students develop better critical thinking, problem solving and spatial understanding skills. MathExplorers offers various features designed to maximize students' learning experience, including: 1. Interactive 3D Visualization with AR; This application allows students to see 3D models of various shapes, such as cubes, blocks, prisms, pyramids, cylinders, cones and balls. With AR technology, students can explore elements such as the number of sides, edges, corner points and find surface area and volume in more detail. 2. Structured Learning Materials; MathExplorers provides learning materials that are in accordance with the Merdeka curriculum, including; definition and characteristics of spatial figures, formula for surface area and volume of spatial figures. as well as example questions with complete discussion. 3. Practice Questions and Automatic Evaluation; MathExplorers provides a variety of practice questions that can help students test their understanding, including; Essay questions that provide detailed explanations after students answer and AR-based challenges that require students to observe a 3D model before answering the questions.
