Bringing AR and spatial computing into the classroom: where should schools start?

AR and spatial computing can turn abstract concepts into 3D content that students can observe and handle, and more and more schools want to use them in class. But getting from an idea to real use in the classroom involves quite a few practical arrangements.

1. Set learning goals first, then choose the technology

Technology is only a tool. Before starting, decide what you want students to learn, such as understanding 3D structures, observing things that are normally invisible, or learning coding and design. With clear goals, it is easier to judge whether AR observation, 3D creation or a coding activity fits best.

2. Make good use of existing devices

Many schools already have iPads, and most AR activities can run on them directly, with no need to buy headsets. Apple Vision Pro and VR devices cost more and are better suited to demonstrations or small-group experiences than to a whole class at once.

3. Lesson arrangements

• Allow time in each lesson for students to get used to the controls
• Work in small groups; two or three students can share one device
• Prepare the room in advance, as AR activities need enough table or floor space
• Have a back-up plan, such as an alternative activity if devices are not charged or the network is unstable

4. Teacher preparation

Teachers do not need to know how to code, but they do need to be familiar with the apps students use and how the lesson runs. One or two teachers can pilot it first, then extend it to other classes once they have some experience.

5. From learning to creating

Besides viewing content, students can create their own, for example building interactive scenes with visual coding, or turning ideas into 3D work with modelling tools. The creative process trains problem-solving, design and communication skills at the same time, and can lead on to inter-school competitions.

6. Look into funding schemes

If the course involves artificial intelligence, schools can check whether the Education Bureau’s AI for Empowering Learning and Teaching Funding Programme applies, and plan the course content to meet the programme’s requirements.
