Technology is the theme that links every other section of the specification together, because no aspect of modern citizenship, whether political, economic or cultural, operates independently of communications technology.
The edexcel igcse global citizenship technology theme examines how digital and energy technologies are reshaping economic development, community life, political participation, and the environment. From a European perspective, where debates about data privacy, digital regulation and energy transition are especially prominent, this theme offers a rich comparative framework for understanding how different countries approach the same technological challenges.
These edexcel igcse global citizenship revision notes cover each topic within the Technology theme, with comparative examples drawn from across the globe and self-check questions to solidify your understanding. If your edexcel igcse global citizenship notes on technology need strengthening, this is the resource to work through.
Technology and economic development
Communications technology has transformed the economic prospects of developing countries in ways that would have been unimaginable a generation ago. The specification focuses on three key connections between technology and development.
Mobile phone banking and business use
In many developing countries, mobile phone technology has leapfrogged traditional banking infrastructure. Kenya's M-Pesa system, launched in 2007, allows users to send money, pay bills, and access financial services through their mobile phones without needing a bank account. By 2023, M-Pesa served over 50 million customers across several African countries. This technology has brought financial inclusion to millions of people who had no access to traditional banks, enabling small businesses to operate, farmers to receive payments instantly, and families to receive remittances from relatives working abroad.
The broader point is that communications technology can accelerate economic development by bypassing infrastructure gaps. Countries that lack extensive road networks, branch banking systems, or postal services can still connect their citizens to economic opportunity through mobile technology.
Trade and investment across national boundaries
The internet has made it possible for businesses in any country to reach global markets. E-commerce platforms allow artisans in rural India to sell products to customers in Europe. Cloud computing enables companies in Nigeria to provide outsourced services to firms in the United States. These connections create new jobs and services, but they also raise questions about labour standards, taxation, and the distribution of economic benefits.
Tackling inequality
Communications technology can reduce inequality by providing access to education, healthcare, and employment opportunities that were previously restricted by geography. Online learning platforms reach students in remote areas. Telemedicine connects patients in rural communities with specialists in urban centres. Job platforms enable workers to find opportunities beyond their immediate locality.
However, the "digital divide" remains significant. Communities without reliable internet access, affordable devices, or digital literacy are excluded from these benefits. The gap between those who can access technology and those who cannot is itself a form of inequality that requires attention.
Technology and communities
International community building
Communications technology enables migrant and diaspora communities to maintain connections across borders in ways that were impossible before the internet age. The Indian diaspora, one of the largest in the world, uses platforms such as WhatsApp, video calling, and social media to maintain family ties, participate in cultural events, and engage in the political and economic life of their home country. Nigerian, Filipino, and Chinese diaspora communities display similar patterns.
This connectivity has profound implications for identity and belonging. A second-generation immigrant in London can watch live religious ceremonies from their family's village, participate in online discussions about homeland politics, and share cultural traditions with their children, all through technology. The result is that diaspora identities are more layered and connected than they were for previous generations.
Opportunities and threats
New technologies create both opportunities and anxieties for communities. The specification requires you to consider differing views on developments such as:
- Artificial intelligence: AI promises advances in healthcare diagnostics, personalised education, and scientific research. But it also raises concerns about job displacement, algorithmic bias, and the concentration of power in technology companies. The European Union's AI Act, adopted in 2024, represents the world's most comprehensive attempt to regulate AI, setting a precedent for other regions.
- Healthcare technology: Bionics and advanced prosthetics improve quality of life. Genetic screening raises ethical questions about privacy and consent. Telemedicine increases access but cannot replace in-person care for all conditions.
Threats across national boundaries
Technology also creates new threats that do not respect borders:
| Threat | Description | Example |
|---|---|---|
| Identity theft | Criminals use stolen personal data to impersonate victims, access financial accounts, and commit fraud | Large-scale data breaches at companies holding millions of customer records have exposed personal information worldwide |
| Computer viruses and malware | Malicious software disrupts systems, steals data, or demands ransom | The WannaCry ransomware attack in 2017 affected hospitals, businesses and government systems in over 150 countries, including shutting down parts of the UK's National Health Service |
| Cyberterrorism | Use of digital attacks to cause disruption, fear, or damage to critical infrastructure | Attacks on power grids, water treatment facilities, and financial systems pose risks to public safety and national security |
Technology, politics and citizenship
Campaigning and social media
Communications technology has transformed political campaigning. Social media platforms allow politicians and citizens alike to reach large audiences quickly and cheaply. The Arab Spring of 2011 demonstrated how platforms such as Twitter and Facebook could be used to organise protests, share information, and mobilise citizens in the face of government censorship. More recently, movements such as Black Lives Matter have used social media to raise global awareness of racial injustice.
However, social media also enables the spread of misinformation, echo chambers, and manipulation. The challenge for democratic societies is to harness the empowering potential of digital communication while guarding against its distortions.
Technology during elections
Citizens and politicians increasingly use communications technology during elections. Candidates use social media for advertising, fundraising, and direct engagement with voters. Citizens use online platforms to research candidates, share opinions, and organise. Some countries have experimented with electronic voting, though concerns about security and transparency persist.
Censorship and bias
The specification requires you to study censorship and bias in relation to communications technology using two countries as examples. Consider the contrast between the following:
- China: The Chinese government operates extensive internet censorship through the "Great Firewall," blocking access to platforms such as Google, Facebook, Twitter, and many international news sites. The stated rationale is social stability and national security. Citizens who circumvent these restrictions risk legal consequences.
- Sweden: Sweden consistently ranks among the world's freest countries for press freedom and internet access. The government protects freedom of expression as a constitutional right, and internet access is widely available and unrestricted. The contrast with China illustrates how different political systems approach the relationship between technology, freedom, and control.
Technology, energy and climate change
The link between technology and climate change operates in both directions. Technology contributes to climate change through energy consumption and manufacturing, but it also provides the tools needed to address it.
Energy-saving technologies
Energy-efficient appliances, LED lighting, smart building systems, and energy-efficient urban design all reduce the amount of energy needed to maintain modern lifestyles. The European Union's energy efficiency directives have set binding targets for member states, driving innovation in building standards, appliance ratings, and industrial processes.
Renewable energy alternatives
The transition away from fossil fuels toward renewable energy sources is one of the most significant technological shifts of the current century:
- Solar power: Rapidly falling costs have made solar energy competitive with fossil fuels in many regions. Countries such as Germany, China, and India have invested heavily in solar capacity.
- Wind power: Both onshore and offshore wind farms generate significant electricity in countries such as Denmark, the United Kingdom, and the United States. Denmark generates over 50% of its electricity from wind.
- Nuclear power: Provides low-carbon electricity but raises concerns about safety (Chernobyl in 1986, Fukushima in 2011), waste disposal, and cost. France generates approximately 70% of its electricity from nuclear power, making it one of the lowest-carbon electricity systems among major economies.
Each of these technologies also generates local issues: visual impact of wind turbines, land use for solar farms, and community concerns about nuclear safety.
Technologies for future climate adaptation
Carbon capture and storage (CCS) technology aims to capture carbon dioxide emissions from industrial processes and store them underground. Flood barriers and coastal defences protect communities from rising sea levels. The Thames Barrier in London and the Delta Works in the Netherlands are engineering responses to flood risk that illustrate how technology can help societies adapt to the consequences of climate change that are already locked in.
Social media identities and freedoms
Social media has become a central part of how people, particularly young people, construct and express their identities. The specification covers three aspects of this phenomenon.
Identity and social media: Social media allows people to curate their online identities, connect with communities of shared interest, and explore aspects of their identity that may not be expressed in their offline lives. This can be empowering (connecting LGBTQ+ young people with supportive communities, for example) or harmful (cyberbullying, unrealistic beauty standards, pressure to present a perfect life).
Rights and freedom of speech: Social media platforms operate across national boundaries, creating tensions between different legal frameworks for free expression. Content that is legal in one country may be illegal in another. Platforms must navigate questions about content moderation, hate speech, and the balance between free expression and harm prevention.
Changing media consumption: The decline of printed newspapers and the rise of 24-hour online news reporting have transformed how people access information. This shift raises questions about the quality and reliability of news, the role of editorial standards, and the vulnerability of online news consumers to misinformation.
Citizenship in action: technology
The final section of the Technology theme asks how citizens can engage with technological change:
- Campaigning about safety or censorship issues
- Understanding the role of law-making in supporting technology access or protection (broadband availability, online libel, child protection)
- Promoting technological skills and helping other citizens understand the benefits and risks of social media
- The work of schools, charities, NGOs, and international organisations in improving access to technology in the classroom
Organisations such as Code.org and the Raspberry Pi Foundation work to promote digital literacy and coding skills among young people worldwide. In many developing countries, NGOs partner with governments to provide schools with computers, internet connectivity, and teacher training. These initiatives represent citizenship in action: using technology to expand opportunity and reduce inequality.
