3. Enhance - Strengthening Understanding of GMO Impacts Through AR

3.1 Deepening Conceptual Understanding Through AR

AR allows students to explore genetic modification as a dynamic process rather than a static concept. By interacting with AR scenarios, learners can observe how genetic changes lead to specific organism traits and how these traits may affect agricultural systems and ecosystems.

Through AR-based visualisation, students can:

• examine genetic changes step by step,
• observe differences between modified and non-modified organisms,
• explore multiple possible outcomes resulting from a single genetic modification.

This interactive approach supports deeper conceptual understanding and helps students connect biological mechanisms with real-world consequences.

3.2 Making Complex Systems More Accessible

The impact of GMOs often involves interconnected systems, such as food chains, ecosystems, and human activities. AR supports systems thinking by allowing students to visualise these relationships in an integrated way.

By interacting with layered AR content, learners can:

• identify cause–effect relationships,
• understand how changes in one part of a system influence others,
• explore trade-offs between benefits and risks.

This makes AR particularly suitable for addressing the complexity of biotechnology topics, where simple answers are rarely sufficient.

3.3 Increasing Engagement and Active Participation

AR encourages students to take an active role in their learning. Instead of passively receiving information, learners interact with scenarios, answer questions, and test their own understanding. When students create their own AR-based questions or scenarios, engagement increases further, as they take ownership of both content and assessment.

Collaborative use of AR also supports discussion and peer learning. Students compare interpretations, justify their choices, and reflect on different perspectives related to GMO use and regulation.

3.4 Practical Integration of AR Tools

In this learning unit, AR tools such as Delightex🔗 are used to support exploration, assessment, and creation. Practical ways to integrate AR include:

• using AR-based tests with scoring to assess initial understanding,
• embedding explanatory text and questions directly into AR scenes,
• allowing students to design simple AR scenarios that model GMO impacts,
• using AR projects as discussion starters and reflective tools.

These practices align with how AR is increasingly used in STEM education worldwide to support inquiry, modelling, and evidence-based discussion.

3.5 Encouraging Reflection and Further Exploration

The Enhance phase supports reflection by encouraging students to evaluate both the technology and the topic itself. Learners reflect on how AR influenced their understanding of GMOs and how digital modelling can support informed decision-making in science and society.

By linking biological knowledge, AR technology, and real-world challenges, this phase encourages students to continue exploring biotechnology topics beyond the learning unit and to engage critically with emerging scientific innovations.
