Think about how different school, the doctor’s office, shopping and even police work look today compared with 20 years ago. ICT has changed all of them – mostly for the better, but with some problems too. In this post you will assess the impact of ICT on education, medicine, business, law enforcement and recreation, including the economic effects.

Build on what you learned in Forms 1–3

These Lower School ICT posts cover the basics of this topic:

• Careers in ICT – how ICT is used at work
• Wikis for online collaboration – learning together online
• VoIP – talking over the Internet

In this post:

• Education
• Medicine
• Business
• Law enforcement
• Recreation
• Writing an “assess” answer

Education

• Access to information: students can research any topic online, use e-books and video lessons.
• Reach (distance teaching): students in rural areas or on small islands can take classes online; schools kept teaching during COVID-19 closures.
• Collaborative teaching and learning: shared documents, Google Classroom, video calls and wikis let students and teachers work together.
• Online tutoring: help from tutors anywhere, at any time.
• Plagiarism: copying and pasting other people’s work is easier – schools use plagiarism checkers.
• Economic: cost of devices and Internet can widen the gap between richer and poorer students.

Medicine

• Access to information: doctors look up the latest research; patients read about conditions and treatments.
• Telemedicine and eHealth: consultations by video call, online appointment booking and electronic health records.
• Expertise at a distance: e.g. teleradiology – X-rays taken in Tobago can be read by a specialist in Trinidad or abroad.
• Quality of care: faster diagnosis, computerised equipment, fewer lost records.
• Self-diagnosis: people may search symptoms online and misdiagnose themselves or delay seeing a doctor.
• Economic: equipment is expensive, but patients save time and travel costs.

Business

• E-commerce: buying and selling online; small Caribbean businesses can sell to the whole world.
• Electronic point of sale (EPOS): barcode scanners and card machines speed up checkout and update stock automatically.
• Telecommuting: employees work from home using the Internet, saving travel time and office costs.
• Email and video conferencing: fast, cheap communication with customers and suppliers.
• Economic: lower costs and new markets, but some jobs are lost to automation and online competitors.

Law enforcement

• E-surveillance: CCTV cameras, licence-plate recognition and monitoring of online crime.
• Databases: criminal records and fingerprint databases (biometrics) shared between police forces.
• Forensics: recovering evidence from phones and computers.
• Communication: faster response with GPS-tracked patrol cars and emergency hotlines.
• Concerns: privacy, misuse of surveillance and the cost of systems.

Recreation

• Streaming music, movies and live sport (watching carnival or a cricket match online).
• Video games, online multiplayer gaming and esports.
• Social media for keeping in touch with family abroad.
• Booking tickets, tours and hotels online – important for Caribbean tourism.
• Concerns: too much screen time, less physical activity, addiction to games or social media, health problems such as eye strain.

Writing an “assess” answer

Give the positive impact, the negative impact and a short conclusion. Example: “Telemedicine lets patients in rural areas see specialists without travelling, saving time and money. However, it needs a reliable Internet connection and some conditions still need a physical examination. Overall, it improves access to healthcare.”
