AI2: Lesson 3 Natural Language Processing How AI 'Understands
Can AI really ‘understand’ what we mean - or is it just guessing?
This KS3 / lower secondary computing lesson shows students how AI tries to 'understand' human language - and where it goes wrong.
This engaging lesson dives into the world of Natural Language Processing (NLP), revealing how AI systems attempt to interpret sentence meaning using logic, rules, and keyword scoring.
Students take control of a simulated sentiment analyser, apply scoring rules, and test the results against subtle or ambiguous language. They then refine the analyser to improve its accuracy - learning first hand why AI struggles with ambiguity, tone, and context.
A final reflection challenges students to judge the limits of AI's language ability using bold, real-world statements. A sharp, analytical lesson that bridges grammar, computing, and digital ethics.
Through this, students uncover:
• How rule-based systems score language using word-level logic and fixed sentiment rules
• Why ambiguity, tone, and syntax can lead to misinterpretations in NLP
• What makes AI ‘understanding’ different from real human comprehension
