Jovy introduces her Grade 6 students in Hong Kong to the Systems Thinking Iceberg using the popular cartoon Doraemon. She uses the moment when Nobita, the main character, is told off by his mum for hiding his test paper from her.
His mum said that she wasn't angry because he got 0, but because he was being dishonest. The cartoon reveals that this was not the only hidden test paper! The students explore the underlying structures that led to this event.
