Deepening Understanding of Complex Concepts

Within the Delightex scene, students interact with AR elements that support understanding of genetic disorders, including:

• the double-helix structure of DNA and its role in replication and transcription,
• point mutations and their effects on protein synthesis,
• chromosomal changes such as trisomy or deletions linked to disorders like Down syndrome or Turner syndrome,
• the pathway from a DNA mutation to physical symptoms caused by faulty proteins.

These concepts are presented through embedded AR models and visual panels rather than static diagrams. Using tools such as MoleculAR and Genome AR integrated into the Delightex workflow, students can rotate, zoom in, and explore genetic structures step by step. This supports spatial understanding and helps learners see how small genetic changes can lead to significant health effects (NHGRI, 2024).

Active Learning and Engagement inside Delightex

Delightex transforms the Enhance phase into an active learning mission, not a passive review. Instead of watching videos or reading long texts, students complete guided tasks directly in the Delightex environment.

Learners engage through:

• interaction with AR models placed inside the scene,
• short Delightex information panels guiding observation and thinking,
• mission-style tasks (e.g. analysing a mutation or solving a case study),
• peer discussion based on prompts displayed in the scene.

This approach supports intrinsic motivation and encourages students to take ownership of their learning. Active participation has been shown to improve understanding of complex biological processes, especially in genetics education (Wallis, 2018).

Delightex Tools and Learning Structure

In this phase, Delightex is used to combine multiple learning elements:

• AR objects (DNA, genes, chromosomes, proteins) for exploration and observation
• Information panels explaining key ideas in short, student-friendly language
• Case study panels presenting real-life genetic scenarios
• Reflection panels guiding ethical discussion and personal response

External AR tools such as MoleculAR, Genome AR, or Merge EDU are used as content sources, while Delightex remains the main platform that structures the learning process and assessment.

Connecting Genetics to Real-World Contexts

Delightex scenes also support real-world application of genetic knowledge. Through AR-supported scenarios, students explore roles such as genetic counsellors or patients and reflect on how genetic information is used in healthcare.

These tasks help learners understand how genomic science affects individuals and society, supporting interdisciplinary learning across biology, ethics, and technology (NHGRI, 2024).

Inclusive and Personalised Learning with Delightex

Delightex supports inclusive learning by offering:

• visual explanations that support learners with different language backgrounds,
• short, layered content instead of long texts,
• self-paced exploration of AR elements within the scene.

Students can revisit panels and models as needed, which supports confidence and independent learning.
