General topic of the learning path	Bio-photonics
Specific name of the learning unit	Photobiomodulation – How Low-Level Light Helps the Body Heal
Age of the target users	16-18 years
Requirements for the learner	To fully benefit from this learning unit on Photobiomodulation (PBM), learners should have a basic understanding of human biology, including cells, mitochondria, and energy metabolism. Familiarity with light properties, such as wavelength and intensity, will help in understanding how red and near-infrared (NIR) light interacts with tissues. Learners should also be comfortable with digital learning environments and using interactive tools, as the unit includes Augmented Reality (AR) simulations, quizzes, and hands-on exercises. Critical thinking and curiosity are encouraged to analyze observations and reflect on real-world applications of PBM in health, sports, and daily life. No prior experience with phototherapy is required, but an interest in exploring how low-level light can stimulate cellular processes and support tissue healing will enhance the learning experience.
Description of the learning unit	This learning unit on Photobiomodulation (PBM) introduces students to the scientific principles and practical applications of low-level red and near-infrared (NIR) light in supporting cellular energy and tissue healing. Through a combination of theoretical explanations, interactive exercises, and Augmented Reality (AR) simulations, learners explore how light penetrates skin, fat, and muscle layers to reach mitochondria, triggering ATP production and promoting repair and regeneration. The unit includes hands-on activities that allow students to observe cellular processes, analyze the effects of different light parameters, and reflect on real-world applications, such as wound healing, muscle recovery, and overall wellbeing. By integrating science, technology, and experiential learning, the unit helps students connect abstract biological concepts to practical outcomes, fostering both understanding and critical thinking about the therapeutic potential of PBM.

Key qualifications, skills and knowledge that can be acquired	By completing this learning unit, students acquire a solid understanding of the scientific principles behind photobiomodulation (PBM), including how red and near-infrared (NIR) light interacts with biological tissues and stimulates mitochondrial activity. Learners gain knowledge of cellular energy production, ATP synthesis, and the role of light in supporting tissue repair and regeneration. They develop practical skills in observing and analyzing biological processes through interactive exercises and Augmented Reality (AR) simulations, enhancing their ability to interpret complex phenomena visually and conceptually. Critical thinking and problem-solving are strengthened as students reflect on experimental results and predict the effects of PBM in various contexts. Additionally, learners enhance their digital literacy and competence with interactive tools, preparing them to apply theoretical knowledge to real-world scenarios in health, sports, or clinical applications.
Resources and didactic aids used	This learning unit employs a variety of resources and didactic aids to support both theoretical understanding and practical experience. Key resources include scientific texts, diagrams, and animations that illustrate cellular structures, mitochondrial function, and ATP production. Short videos and visual comparisons help students grasp how red and near-infrared (NIR) light interacts with tissues and stimulates healing processes. Augmented Reality (AR) simulations allow learners to explore light penetration, mitochondrial activation, and tissue repair in an immersive, interactive environment, making invisible biological mechanisms visible. Worksheets, guided exercises, and quizzes reinforce learning, while case studies highlight real-world applications in clinical, sports, and wellness contexts. These tools are complemented by digital platforms and collaborative discussion spaces, enabling students to share observations, reflect on outcomes, and connect theoretical concepts to practical applications, ensuring an engaging and comprehensive learning experience.
Assessment criteria and evaluation	Learners will be assessed based on their understanding of photobiomodulation principles, ability to apply theoretical knowledge to practical scenarios, and engagement with interactive exercises. Assessment criteria include accurate identification of light wavelengths, tissue layers, and mitochondrial responses, correct interpretation of ATP production mechanisms, and the ability to explain how PBM supports tissue healing and recovery. Students’ participation in Augmented Reality (AR) simulations and completion of guided exercises will be evaluated, including their capacity to manipulate variables, make observations, and draw evidence-based conclusions. Reflection activities and quizzes will assess critical thinking and the ability to connect cellular processes to real-world applications. Collaboration, clarity of explanations, and depth of understanding will also be considered. Evaluation combines formative assessment through interactive tasks and quizzes, with summative assessment based on reports, presentations, and reflection outputs, ensuring a comprehensive measure of both knowledge and applied skills.
