Enhance

In this phase, learning is deepened and extended through reflection, visual reinforcement, and meaningful connections to real-world science. Augmented Reality (AR) plays a key role by helping students move from basic understanding to critical thinking and personal interpretation of genomic knowledge.

Using Delightex, students revisit key ideas from the Human Genome Project through interactive 3D models and short media resources. For example, DNA and chromosome models are explored again, but this time with a focus on function and application, not only structure. Students can rotate and examine chromosomes while reflecting on how genome mapping made it possible to identify genes linked to diseases and traits (NHGRI, 2024). This repeated interaction supports long-term retention and conceptual clarity.

To strengthen understanding, learners engage with short, high-quality explanatory videos linked inside the AR environment. One effective example is the video “The Human Genome Project Explained” by TED-Ed, which summarises the goals, challenges, and outcomes of the project in a visually engaging way suitable for secondary students:

After watching, students answer reflection questions such as how genome knowledge has changed medicine and whether similar large-scale projects should be funded in the future (Collins et al., 2003).

Genome-related AR tasks also help students connect scientific content to modern medicine. For instance, learners explore highlighted genes linked to health conditions and discuss how genome sequencing supports early diagnosis and personalised treatment. This directly links the Human Genome Project to genomic medicine, helping students see its relevance beyond history (Green & Guyer, 2015).
As enrichment, students may explore the NHGRI page “Genomics and Medicine”, which explains real applications in accessible language:

Gamified learning elements further enhance motivation. In Delightex, teachers can design short “genome missions” where students collect information, unlock content, or complete challenges such as identifying the correct role of genome databases or matching sequencing technologies to their purpose. These activities support active learning while keeping cognitive load manageable for B1–B2 learners.

Ethical reflection is also strengthened in this phase. Students revisit ethical questions introduced earlier, such as genetic privacy or access to genome data, and link them to present-day debates. AR panels may include short case examples and guiding questions connected to the ELSI program of the Human Genome Project, encouraging learners to form and justify their own opinions (Green & Guyer, 2015).
An additional reference resource is the NHGRI ELSI overview:

To demonstrate learning outcomes, students may create short explanations using screenshots from AR scenes or record brief video reflections describing what they learned about genome sequencing or ethical responsibility. These outputs help combine scientific understanding, digital literacy, and communication skills.

Overall, the Enhance phase supports deeper understanding, reflection, and transfer of knowledge. By combining AR exploration, trusted scientific resources, and guided reflection, students strengthen their ability to understand genomics as both a scientific and societal field. This prepares them for future learning in biology, medicine, and biotechnology, while encouraging informed and responsible thinking about genetic data.
