This training unit provided learners with a clear and structured understanding of genetic mutations, including their causes, types, and biological significance. Students explored how mutations arise through DNA replication errors and environmental factors, and how these changes can have harmful, neutral, or beneficial effects on organisms. By connecting scientific explanations with familiar examples from popular culture, such as “superpowers,” the unit helped learners critically distinguish between Hollywood fiction and biological reality.

The integration of Augmented Reality (AR) activities in Delightex played a key role in supporting understanding. Through interactive 3D models and simulations, students were able to visualise DNA structures, mutation processes, and chromosomal rearrangements that are difficult to grasp through text alone. These AR-based experiences made abstract genetic mechanisms tangible and supported deeper conceptual learning.

Across the Explore, Execute, and Enhance phases, learners developed not only biological knowledge but also analytical, reflective, and creative skills. They practiced identifying mutation types, analysing their effects, and linking genetic variation to real-world contexts such as disease, evolution, and biotechnology. Gamified elements and collaborative tasks increased engagement and motivation, while reflection activities encouraged students to think about the broader implications of mutations.

Overall, this unit successfully connected the initial learning objectives with meaningful learning outcomes. By combining scientific accuracy, AR-supported exploration, and bio-inspired thinking, the unit encourages continued curiosity and provides a strong foundation for further study in genetics, medicine, and biological sciences.

Phase Description
Explore

- Research and Discovery: : Students study key mutation types (point mutations, insertions, deletions, duplications, inversions, and translocations). They explore mutation causes, including DNA replication errors and environmental influences such as radiation and chemicals.

- Content Development: Learners work with adapted scientific texts, diagrams, and visual materials explaining mutations, genetic diseases, DNA repair mechanisms, and the role of mutations in evolution. Visual and AR-ready content is introduced to prepare students for interactive exploration in Delightex.

- Needs Analysis: Teachers assess prior knowledge through short discussions or diagnostic questions. Learning needs and misconceptions are identified to adjust explanations and AR tasks for better understanding.
Execute


- Curriculum Implementation: Students engage in hands-on lessons using Delightex to explore 3D DNA and chromosome models. AR scenes simulate mutation processes such as replication errors, frameshift mutations, and chromosomal rearrangements.

- Interactive Exercises: Learners observe how mutations form and affect genes by interacting with AR models. They classify mutation types, analyse their biological impact, and explain outcomes using visual evidence from the AR environment.

- Feedback Collection: Embedded AR quizzes and interactive checkpoints provide immediate feedback. Teacher-guided discussions and short reflections help consolidate understanding and address errors.
Enhance

- AR Integration: Delightex is used to create immersive environments where students manipulate DNA and chromosome models independently. Learners revisit complex concepts through self-paced AR exploration, strengthening retention and confidence.

Gamified Content:

- Points and Badges: Awarded for correctly identifying mutation types and explaining their effects.
- Quests and Levels: Students progress from simple mutations to complex chromosomal changes.
-Collaborative Gamified Tasks: Small groups work together to analyse mutation scenarios and present findings.

AR-Based Assessments: AR quizzes and visual explanations are used to assess understanding in real time.Results help teachers identify knowledge gaps and support personalised feedback
