What an incredibly stupid thing to do! As a teacher, you should NEVER use your position of authority to scare your students or willingly tell them lies. These students will never trust or respect that teacher again.
The teacher was pretty stupid, but these 14-year-olds were certainly a lot more stupid, IMHO
I disagree. I gather from the article that these students were informed of this 'catastrophe' at a gathering, i.e. NOT in their normal classroom situations. They were assembled in a big room, all 300 of them, without having a clue what they needed to be there for. They were then 'informed' of this pending catastrophe, and TOLD TO
GO HOME to say farewell to their families!!
An unfamiliar situation and surrounding + a dramatic message = 'success' guaranteed.
If they did this at a company with adults, many would fall for it!
