By following the Explore–Execute–Enhance pathway, students gain a strong foundation in genetics and CRISPR-Cas9, experience the editing process in a safe virtual environment, and reflect critically on the potential and risks of gene editing.

The mission correcting a faulty gene becomes a metaphor for their role as future scientists and responsible citizens: learning not only how to use technology, but also how to think about its impact on life and society.

Phase Description
Explore

- Research and Discovery: Learners begin by exploring the fundamentals of DNA and genes. DNA is explained as the “instruction manual for life,” with genes as specific sentences that code for proteins. Mistakes in these instructions can cause diseases. CRISPR-Cas9 is introduced as a revolutionary tool discovered in bacteria that allows scientists to “cut and edit” DNA like fixing a typo in a book.

Students discover the natural origin of CRISPR as a bacterial immune defense, and how scientists adapted it for genetic engineering. Case studies (e.g., CRISPR use in correcting sickle-cell anemia) provide concrete, real-world examples.

- Content Development:

  • What DNA and genes are.
  • How CRISPR-Cas9 works step by step (guide RNA, Cas9 enzyme, DNA repair).
  • Applications in medicine, agriculture, and conservation.
  • Ethical debates: curing vs. enhancing, “designer babies,” unintended consequences.

- Needs Analysis:

  • A clear, visual explanation of CRISPR’s mechanism.
  • An understanding of why gene editing matters for human health and society.
  • A safe way to see and interact with DNA editing, which prepares them for AR-based practice.
Execute


- Curriculum Implementation: In this phase, learners move from knowledge to practice. Through an Augmented Reality laboratory, students are virtually transported inside a 3D cell. They see a giant DNA strand floating in space, and their mission is to use CRISPR-Cas9 to correct a faulty gene.

- Interactive Exercises: 
The AR experience guides students through key steps:

  • Identify the faulty gene – scanning DNA strands to locate the “mutation.”
  • Design a guide RNA – selecting the right match for the target sequence.
  • Activate Cas9 – watching the enzyme cut DNA at the exact spot.
  • Repair DNA – inserting a corrected sequence and observing the cell heal itself.
  • Students “work with” digital DNA in real time, making the invisible process visible and interactive.

- Feedback Collection: 

  • Team discussions on which diseases could be treated with CRISPR.
  • Comparing traditional breeding or genetic engineering to CRISPR precision.

Teachers can monitor results through the AR platform, while students log reflections in a digital lab journal. Peer review is included: groups exchange feedback on strategies and challenges.
Enhance

- AR Integration: 

The AR system provides immediate feedback:

  • Did the student select the correct guide RNA?, Was the DNA cut at the right point?, Was the repair successful?

- Interactive Learning: 

Here, AR becomes a deeper learning tool. Students can manipulate 3D DNA strands, zoom in on molecules, and test what happens if edits are wrong. AR bridges abstract genetic theory with tangible practice.

Gamified Content:

Points and Badges: Beyond the technical process, learners reflect on applications and implications
Leaderboards: track team progress in AR missions.
Quests and Levels: scenarios increase in difficulty (fixing a single mutation → editing multiple genes)..
Rewards for Exploration: extra recognition for testing new approaches or finding alternative solutions.
Collaborative Gamified Tasks: teams must cooperate to edit multiple genes in a shared “virtual organism.”

AR-Based Assessments:  

  • Students are given faulty DNA and must edit it correctly.
  • They explain each step (guide RNA design, cut, repair).
  • Performance is measured not only on correct results but also on reasoning, teamwork, and creativity.

Teachers use AR data logs and reflective journals to evaluate knowledge, skills, and critical thinking.
