From Asymptomatics to Zombies: Visualization-Based Education of Disease Modeling for Children

Paper Information

• Subject Area: Application of disease transmission simulation and visualization tools in children's education
• Keywords: Disease transmission, visualization, children, education, computational modeling

Research Background and Problem

• Problem or Challenge: During the COVID-19 pandemic, disease transmission visualizations primarily focused on explaining epidemic models and spread to adults. Although children were directly affected, they lacked educational opportunities in this area. This situation limited children's understanding of the pandemic and public health interventions.
• Significance: Educating children about disease transmission and modeling principles can not only enhance their scientific understanding but also foster computational thinking skills and interest in STEM disciplines.
• Motivation and Related Work:
  • The application of disease transmission models and visualization tools in public health has been extensively studied, but these studies typically focus on professional use.
  • Experimental disease transmission visualizations have been used in news media, but these designs mainly aim to convey simple concepts and lack depth for educational purposes.
  • There is a lack of specifically designed tools and methods to help children understand the complexities of disease transmission, such as the impact of asymptomatic carriers.

Solution

• Proposed Solution:

  • Developed an interactive and accessible visualization tool to help children learn the principles of disease transmission in computational models.
  • Created a workshop on disease transmission that combines “unplugged activities” with visualization tools, integrating fun and educational elements.

• Innovations:

  • Translated complex concepts of disease transmission (e.g., asymptomatic carriers, vaccination) into visual and interactive experiences that are easy for children to understand.
  • Used a particle-based crowd model while incorporating daily commuting patterns between homes and workplaces to enhance the realism of the model and its relatability for children.
  • Designed a progressive learning path, starting from simple physical activities to more complex digital models.

• Implementation Steps and Key Techniques:

  1. Workshop Design:
     • Introduced basic concepts (e.g., infection probability, networks) through classroom demonstrations.
     • Organized “unplugged activities” to simulate disease transmission physically, such as using strings to trace transmission paths.
     • Gradually introduced interactive visualization tools to help children transition smoothly to complex computational models.
  2. Visualization Tool Development:
     • Designed a simple “particle crowd” model using static particles to represent groups and transmission processes.
     • Developed an advanced model incorporating commuting patterns between homes and schools/workplaces, as well as parameters like asymptomatic carriers, quarantine, and vaccination.
     • Provided real-time parameter adjustment functionality, enabling children to experiment and understand the interactions between variables in the model.
  3. Iterative Design:
     • Collaborated with epidemiologists and education experts to develop the tool, adjusting model complexity and interface intuitiveness based on multiple rounds of feedback.

Research Outcomes

• Specific Outcomes:

  • Successfully built an educational and interactive visualization tool, combined with a workshop to teach children the basic concepts of disease transmission models.
  • The workshop and visualization tool have been implemented in schools over 40 times, reaching more than 1,200 children and continuing to attract approximately 100 students monthly.

• Advantages:

  • The combination of workshop format and visualization tools sparked children's interest in STEM disciplines. Self-assessment reports from students showed a significant improvement in understanding disease transmission and modeling.
  • Provided children with opportunities to participate and experiment, allowing them to explore and learn independently by adjusting model parameters and observing different infection outcomes and the effects of public health interventions.

• Experimental and Evaluation Results:

  • Questionnaire surveys showed strong interest and learning outcomes in disease transmission simulations among students. Teachers and workshop facilitators also reported high levels of engagement.
  • Students rated the workshop highly (63% chose “excellent”). Post-workshop surveys indicated increased interest in STEM disciplines, with a significant rise in interest in computational sciences.

• Limitations and Future Directions:

  • Children found some terminology (e.g., “asymptomatic carriers”) challenging to understand, requiring further simplification or supplementary explanations.
  • Certain particle interaction designs, such as “exposure radius,” were not fully comprehensible to younger students.
  • Future research could explore more complex town layout simulations to enhance the dynamic complexity of infection modeling and learning possibilities. Additionally, efforts should focus on better balancing gamification with educational objectives.
