Technology development in education has opened up new opportunities to improve learning effectiveness, one of which is passed through the technology of Augmented Reality. AR is a technology that combines the real world with virtual elements, allowing users to see 3D objects in their surroundings through devices like smartphones or tablets. In education, particularly in geometry learning, this technology offers more interactive and profound experiences. Students can visualize geometry objects in 3D, understand their properties, and manipulate them to get a better understanding.

This article will talk about AR benefits in geometry learning, some examples of application, and the challenges faced in the application of this technology in the classroom.

1. Why Augmented Reality Effective for Geometry Studies?

Geometry is a mathematical branch associated with shape, size, relative position, and the nature of space of the object. One of the challenges in geometry learning is to help students understand abstract concepts such as 3D, angles and spatial relationships. AR use can help students visualize and manipulate geometry objects in a real environment.

The main benefit of AR in geometry study is:

• facilitating Visual Comfort: With AR, students can see the form of geometry in reality and study the properties and relationships of various perspective.
• More Interactive Learning: Students can interact directly with 3D objects, which help them to understand the concept of hard geometry if only theoretically taught.
• Increase Motivation and AttractionAR technology gives new and exciting learning experiences, which makes students more enthusiastic about learning geometry.

According to research on Education Technology Research and Development, the use of AR in education helps improve student understanding and interest in subjects that require complex visualization, such as geometry.

2. AR Applications Example in Geometry Studies

AR technology offers various innovative opportunities in geometry learning. Some examples of the application are as follows:

a. 3D Shape Visualize

One of the most popular AR applications in geometry learning is 3D form visualization, like cubes, prism, pyramids and balls. With the AR app, students can see these shapes in reality on their devices screen and study the properties of every shape, like the number of sides, angles and length of ribs.

For example, using applications like the AR GeoGebra, students can see 3D geometry in different angles and understand how rotation and projections work. They can also zoom in or shrink the size of objects, which helps them understand the concept of scale.

B. Angle and Rotation Learning

Learning about angles and rotation can be a challenge for students who are difficult to visualize the orientation changes of objects. With AR, students could see what 3D is spinning in three-dimensional space. For example, using AR applications, they can see how the corners in the cube change when the object is played.

It allows students to understand the angles between different fields in 3D, as well as how change angles affect the appearance of objects. In the long run, learning with AR helps students master the concept- concept of basic geometry better.

C. Space and Volume Exploration

The concept of space and volume is a key aspect in geometry that is often difficult to understand if it's only taught through a two-dimensional image on a blackboard or a book. With AR, students can see and understand the relationship between object dimensions and the volume produced. They can observe how 3D shapes interact, and understand the volume difference between those shapes.

For example, students can see how a particular base and height prism can have a different volume if the dimensions on one side change. It helps students to directly understand the concept of volume and connect it to real dimensions.

d. Use of AR Application for Geometry Experiment

There are many AR applications that support geometry learning, such as AR Circuits and AR3D Math, that allow students to experiment with the objects of geometry. Through this application, students can try to manipulate objects of geometry, measure corners, or calculate the area and volume directly on display.

The use of these applications also allows teachers to provide an AR-based learning project, where students can learn through live experiments, such as looking at volumes of geometric objects or measuring the distance between points in the shape they create.

3. Use AR benefits in Geometry Studies

The benefit of AR in the study of geometry is not only on the understanding of concepts, but also on the development of relevant skills in the real world. Some of the main benefits that students earn among themselves:

• Spatial Spatial Ability: With 3D visualization in real space, AR helps students develop spatial skills, which are important in engineering, architecture and design.
• Increasing Students'AR technology creates interesting and interactive learning environments, so students are more motivated and involved in learning.
• Connecting Theory with Practical Application: Students not only study abstract concepts, but can also directly apply them in visual form, which strengthens understanding the basic concept of geometry.
• Growing Curiosity and Creativity: With AR, students are driven to experiment with various forms and settings, which can grow curiosity and creativity.

Four. Challenge in AR Applications in Geometry Studies

Although AR offers many benefits, his application in class still faces some challenges, among other things:

• Technology Resource LimitNot all schools have access to devices that support AR technology, like smartphones or tablets. Besides, not all teachers have the skills necessary to utilize AR optimal.
• Stable Internet Access Required: Many AR applications require a stable Internet connection, which may not be available in all schools, especially in remote areas.
• Lack of AR Learning Matter that Contains: The resources and learning materials that use AR for geometry are still limited. Teachers often have to develop their own material or find applications to match the curriculum.

5. Strategy to optimize AR usage in Geometry Studies

Some of the strategies the teacher can use to optimize AR use in geometry are:

• Integrating AR with curriculum: Teachers need to make sure that AR uses not only become additional, but are integral parts of geometry learning. AR can be used as a tool to explain concepts that are elusive students.
• Training for Master: Teachers need to be given skills and knowledge about AR uses in learning. Training can help teachers feel more confident in applying this technology in class.
• Free and Reachable Resources Use: There are free AR applications or low-cost things that can be used by schools and teachers, such as AR GeoGebra or Merge Cube, which provide a lot of geometry content.

Conclusion

The use of Augmented Reality (AR) in geometry learning gives us a great opportunity to increase student understanding of concepts that are often difficult to understand abstract. AR allows students to visualize, manipulate, and interact directly with the object geometry in a three-dimensional form. This technology helps not only the students understand the concept of basic geometry, but also in developing critical, spatial, creative thinking skills.

However, to optimize AR use, there needs to be support for adequate technology resources, teacher training, and good integration with curriculum. Thus, AR can be an effective tool in geometry learning, as well as helping students prepare for the challenges of the increasingly digital and technological world.
