Low-Cost Arduino Framework Enhances STEM Engagement Through Modular Design and Reduced Complexity

Why It Matters

Designing educational tools with a focus on affordability and ease of use is crucial for equitable access to STEM learning. By leveraging existing open-source technologies and adopting a modular approach, designers can create adaptable systems that cater to varying skill levels and project needs, ultimately empowering more students to engage with complex subjects.

Key Finding

The HYDRA framework, built with affordable, open-source components like Arduino, is designed to be easy to learn and use, enabling students with little prior experience to engage in STEM projects, thereby increasing their confidence and creativity.

Key Findings

• The HYDRA framework is low-cost and utilizes open tools.
• The modular design and low complexity contribute to a reduced learning curve.
• The system is suitable for students with limited prior knowledge in programming, embedded devices, and robotics.
• The framework can boost student self-confidence and creativity.

Research Evidence

Aim: How can a low-cost, modular STEM educational framework using open tools be designed to minimize complexity and learning curve for elementary and secondary students?

Method: Framework Development and Preliminary Study

Procedure: A new educational framework, HYDRA, was designed and developed using the Arduino microcontroller and other low-cost, open tools. The system was engineered to be expandable and modular with low complexity. A preliminary study was conducted with 68 elementary school students to assess its usability and impact on engagement.

Sample Size: 68 participants

Context: STEM Education (Elementary and Secondary)

Design Principle

Design for accessibility and adaptability through modularity and open-source integration.

How to Apply

When developing educational tools or kits, consider using readily available, low-cost components and a modular architecture. Focus on creating intuitive interfaces and providing clear, step-by-step guidance to minimize the initial learning curve.

Limitations

The study was preliminary, and further testing with a broader range of students and educational contexts is needed to fully validate the framework's effectiveness.

Student Guide (IB Design Technology)

Simple Explanation: You can make learning science and tech easier and cheaper for students by using simple, affordable parts and designing things in a way that can be easily changed or added to.

Why This Matters: This research shows that making technology for learning affordable and easy to use can help more students get interested in science, technology, engineering, and math.

Critical Thinking: To what extent can the principles of modularity and low-cost design be applied to more complex STEM fields beyond basic robotics and sensor integration?

IA-Ready Paragraph: The HYDRA framework demonstrates that educational tools can be made more accessible and engaging by prioritizing low cost and modularity, leveraging open-source technologies like Arduino. This approach reduces the learning curve and fosters student confidence, suggesting that similar principles can be applied to enhance the effectiveness and reach of educational design projects.
