Computer Science Education: Reflections on E-Waste Reduction through Computer Refurbishment and Repurposing

In this reflective paper, I examine my journey of introducing the student cohort of my Computer Systems Administration and Support (CASA) module to the importance of sustainability and e-waste reduction by engaging them in the collection, refurbishment, and repurposing of personal computers for donations to local African communities. The primary goal was to revamp the stagnant, monotonous lectures that were uninspiring for students and bridge the gap between theoretical knowledge, in-lab practicals with hands on experience, and explorative challenges, while fostering socially responsible affective engagement towards sustainability.<br/><br/>The pedagogical approach of the module was expanded into an andragogical approach via Kolb’s Experiential Learning Cycle, by allowing students to actively engage in hands-on refurbishment without rigid directives. Through this approach, students underwent concrete experiences by working with real hardware and software challenges, followed by reflective observations of their successes and setbacks. One of the key realisations from this experience was that e-waste is a multifaceted issue driven by rapid technological advancements and a lack of backward hardware/software compatibility.<br/><br/>This initiative to prepare future computing professionals to address the growing e-waste challenges has improved classroom communication, encouraged idea exchange, and transformed their perspectives on the role of sustainable technology in society. Academically, it highlighted the need to address the affective domain of learning, ensuring that students see the value and impact of their work. Professionally, it refined my teaching approach, encouraging greater student independence and problem solving skills. Promoting digital inclusion through refurbished computer donations and training has had a profound social impact.
