Understanding environmental issues related to computing is crucial for students as they become more aware of the digital tools they use and the world they inhabit. This topic opens the door to discussions on how technology impacts the environment, positively and negatively, and how individuals can act responsibly.
To make this topic practical and engaging, here are some hands-on, classroom-focused activities and teaching strategies:
Real-World Scenarios and Discussions
E-waste Awareness Campaign:
Start with a class discussion about electronic waste (e-waste). Ask students to bring examples of old devices (broken phones, outdated laptops, or other gadgets). Discuss what happens to these devices when disposed of improperly.
- Use videos or articles that show the effects of e-waste on the environment and human health, especially in South Africa.
- Ask students to research local e-waste recycling centres and create a list of resources for responsible disposal.
Green Computing Practices:
Introduce the concept of “green computing” by discussing practices like energy-efficient devices, turning off equipment when not in use, and reducing paper usage through digital communication and storage.
- Provide a classroom challenge: How much energy can the class save by implementing green practices for one week? Use simple energy calculators or tools to track savings.
Hands-On Activities
Repurposing Old Hardware:
- Ask students to brainstorm creative ways to repurpose old computer parts or devices. For example, old keyboards could be used for art projects, or hard drives could be transformed into clocks.
- This encourages critical thinking (analysis and evaluation in Bloom’s taxonomy).
E-waste Art Competition:
Organise a competition where students create art from non-functioning computer parts. Not only does this promote recycling, but it also adds an element of fun and creativity.
Technology and Sustainability Exploration
Carbon Footprint of Technology:
Provide students with data or a tool to calculate the carbon footprint of producing and using their devices. This can lead to discussions about manufacturing, energy use, and life cycles of technology.
Debates on Responsibility:
Divide the class into groups to debate topics like:
- Should manufacturers be more responsible for recycling e-waste?
- Is it realistic for everyone to switch to energy-efficient devices?
These debates help students apply knowledge (applying and evaluating in Bloom’s taxonomy) and develop their argumentative skills.
Low-Tech Activities for Under-Resourced Schools
If your school lacks digital resources, you can still explore this topic creatively:
Case Study Analysis:
Present printed case studies on companies that have successfully implemented green computing practices. Discuss the environmental and financial benefits.
Role-Playing:
Set up a mock town meeting where students role-play as stakeholders discussing a proposed e-waste recycling initiative. This activity develops communication and problem-solving skills.
Links to Other Subjects
Encourage interdisciplinary collaboration with subjects like Life Sciences (to discuss environmental impact) and Business Studies (to explore the financial aspects of green technology).
For example:
- Partner with Business Studies to create a marketing campaign for an eco-friendly product or service.
- Work with Life Sciences to study the biological effects of toxic materials in e-waste.
Encouraging students to act as eco-advocates in their communities, spreading awareness about proper e-waste disposal and adopting green practices in their homes.
