How ICT Has Changed Education, Medicine, Business, Law Enforcement and Recreation

Aven Brisail1 Comment

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.

  • 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.”

Automation and Job Security: Job Loss vs Productivity Gains

Aven BrisailLeave a comment

Self-checkout machines at the supermarket, ATMs instead of bank tellers, robots welding cars – automation means using computers and machines to do work that people used to do. Is this good or bad for jobs? In this post you will learn to assess the effect of automation on job security, weighing job loss against productivity gains for skilled and unskilled workers.

Build on what you learned in Forms 1–3

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

In this post:

  • What automation is
  • Job loss
  • Productivity gains
  • Skilled and unskilled jobs
  • Retraining and new jobs
  • Making a balanced judgement

What is automation?

Automation is the use of computer-controlled machines, robots and software to carry out tasks with little or no human help. Examples: robots on assembly lines, automated kiosks and self-checkouts, ATMs, online banking, process control in factories and oil refineries, and AI chatbots answering customer questions.

Job loss

  • Machines replace workers who did repetitive tasks – assembly-line workers, cashiers, bank tellers, data-entry clerks, toll booth operators.
  • Workers who used to watch gauges in a plant are replaced by computer process control.
  • Job loss causes unemployment, loss of income and stress for families, and can hurt whole communities.

Productivity gains

  • Machines work 24 hours a day without breaks, so more is produced.
  • Fewer errors and more consistent quality.
  • Safer – robots do dangerous jobs (welding, handling chemicals).
  • Lower long-term costs (although the initial cost is high), so goods can be cheaper.
  • Customers get faster service, e.g. 24-hour ATMs and online banking.

Skilled and unskilled jobs

Unskilled / routine jobsSkilled jobs
Effect of automationMost at risk – repetitive tasks are easy to automate (cashier, packer, data-entry clerk)Often changed rather than replaced – the worker uses new tools (an architect uses CAD, a typist uses word processing, a doctor uses digital scans)
Job securityLower – workers may be laid offHigher, if workers keep their skills up to date
What workers needRetraining for new rolesUpskilling to use new technology

Retraining and new jobs

Automation also creates jobs: people are needed to design, program, install, repair and supervise the machines, and new industries appear (app development, social media management, cybersecurity). Workers whose jobs are automated may retrain – for example a cashier learning to manage the store’s online orders.

Making a balanced judgement

In the exam, “assess” means give both sides and reach a conclusion. For example: “Automated kiosks at a bank will cause some tellers to lose their jobs, but the bank will serve customers faster and 24 hours a day. If the bank retrains tellers as customer advisers, the overall effect can be positive.”

Try it: Job loss or productivity gain?

Decide whether each statement describes job loss or a productivity gain.

An ATM lets customers withdraw cash at midnight
A factory lays off 40 packers after installing robots
Robots weld cars with fewer errors
Toll booth workers are replaced by electronic tags
A machine keeps working through the night with no breaks

Paper 1 practice (multiple choice)

Choose the best answer for each question. Try them all before you check.

1. Which job is MOST at risk from automation?
(A) Software developer
(B) Supermarket cashier
(C) Network engineer
(D) Systems analyst

2. A productivity gain from automation is that
(A) workers lose income
(B) machines can work 24 hours a day
(C) initial costs are high
(D) workers need retraining

3. An architect who now uses CAD software is an example of
(A) job loss
(B) a job changed by technology
(C) piracy
(D) unskilled work

4. One DISADVANTAGE of automation for a business is
(A) higher initial cost of equipment
(B) fewer errors
(C) faster production
(D) safer work

5. Learning new skills to do a different job after automation is called
(A) retraining
(B) telecommuting
(C) outsourcing
(D) encryption

Paper 2 practice (structured question)

A bank in Port of Spain plans to install automated kiosks so customers can deposit cheques and pay bills without visiting a teller.

(a) Define the term automation. (2 marks)

(b) State TWO productivity gains the bank may get from the kiosks. (2 marks)

(c) Explain TWO effects the kiosks may have on the bank’s tellers. (2 marks)

(d) Assess whether skilled or unskilled workers are more likely to lose their jobs because of automation. (2 marks)

Total: 8 marks

Show answers

(a) The use of computers/machines/robots (1) to perform tasks with little or no human involvement (1).

(b) Any two (1 each):
• service available 24 hours
• faster transactions/shorter lines
• fewer errors
• lower long-term staff costs

(c) Any two (1 each):
• some tellers may lose their jobs
• tellers may need retraining for new roles such as customer advisers
• fewer new tellers hired
• changed duties, e.g. supporting customers at kiosks

(d) Unskilled/routine workers are more likely to lose jobs (1) because repetitive tasks are easy to automate, while skilled workers usually adapt by learning to use new technology (1).
