Evaluate IT impacts on society (healthcare, education, surveillance)

Healthcare: From paper charts to AI diagnostics 🏥

Imagine a hospital as a giant library where each patient’s story is a book.

Positive impact: Electronic Health Records (EHR) let doctors read the whole book instantly, reducing errors.
Negative impact: If the library’s computer crashes, the entire book can be lost.

AI in diagnostics: Algorithms can spot patterns faster than a human eye, like a super‑sharp magnifying glass.
Example: A neural network can detect early signs of diabetic retinopathy from retinal scans in seconds.

Exam tip: When answering, balance benefits (speed, accuracy) with risks (privacy, over‑reliance on tech).

Education: Learning in a digital playground 🎓

Think of a classroom as a giant Lego set.

Positive impact: Online platforms let students build knowledge bricks anytime, anywhere.
Negative impact: Too many bricks (apps) can clutter the workspace, making it hard to focus.

Personalised learning: Adaptive quizzes adjust difficulty like a smart treadmill that matches your pace.
Example: Khan Academy’s algorithm recommends next topics based on quiz performance.

Exam tip: Discuss how technology can enhance learning (access, engagement) and challenge it (digital divide, distraction).

Surveillance: The watchful eye of the internet 👁️‍🗨️

Picture a city as a giant chessboard where every move is tracked by cameras.

Positive impact: Surveillance helps catch crime faster, like a detective with a crystal ball.
Negative impact: Constant monitoring can feel like living under a magnifying glass, raising privacy concerns.

Data analytics: Algorithms sift through traffic data to optimise routes, similar to a GPS that learns your habits.
Example: Smart city sensors predict traffic jams before they happen.

Exam tip: Evaluate the trade‑off between security and privacy, and consider legal frameworks (GDPR, Data Protection Act).
