Deepening Understanding

Through Delightex, students interact with 3D models of DNA strands and chromosomes, allowing them to observe how replication errors, insertions, deletions, and chromosomal rearrangements change genetic information. Visualising these processes helps learners understand cause–effect relationships in genetics, such as how a single nucleotide change can alter protein function or disrupt gene regulation (Alberts et al., 2015; Griffiths et al., 2019).

Unlike static textbook images, AR models can be rotated, zoomed in on, and manipulated, which supports spatial thinking and long-term retention of complex biological processes.

Accessibility of Complex Concepts

Mutation types such as frameshift mutations, chromosomal inversions, or translocations are often difficult to understand through diagrams alone. In Delightex, students can explore these mutations step by step, visually following how DNA segments are added, removed, duplicated, or flipped. This interactive approach bridges the gap between abstract genetic theory and concrete understanding, making challenging concepts more accessible to diverse learners (Strachan & Read, 2018).

Increasing Engagement through Gamification

Delightex enables the integration of gamified learning elements that increase motivation and sustained engagement:

• Students earn points or badges for correctly identifying mutation types or explaining their effects.
• Progressive challenges allow learners to move from simple point mutations to complex chromosomal rearrangements.
• Optional collaborative tasks encourage peer discussion and shared problem-solving.

These elements promote active participation and encourage students to take ownership of their learning process.

Building Connections to Real-World Applications

AR-based simulations in Delightex help students link mutation concepts to real-world biological and medical contexts. For example, learners can explore how mutations contribute to genetic diseases, antibiotic resistance, or evolutionary adaptation. By visualising these connections, students better understand why mutations matter beyond the classroom and how genetic variation shapes life on Earth (National Human Genome Research Institute, 2023).

Educational Impact

By integrating AR through Delightex in the Enhance phase, students move beyond memorisation toward conceptual understanding, critical thinking, and reflection. The immersive AR environment supports different learning styles, reinforces scientific literacy, and encourages curiosity about genetics, evolution, and biotechnology. This approach lays a strong foundation for future studies in biology while helping students critically evaluate both the benefits and risks of genetic change.
