Foreign language instruction should begin in kindergarten

Does it work?

For some people, yes. It makes you focus on the question and it gets you thinking. It also helps that you have something positive to do. A danger in the 1 minute is that you sit and look at the piece of paper and you get no words or ideas. Your mind is less likely to go blank if you need to write a sentence.

Any problems?

Writing and speaking are 2 different skills. You don’t need writtten language, you need spoken language. (Some of the worst advice I have seen says that you should try and use “one” instead of “you”.) It just seems wrong to spend time writing a sentence, when you are planning to speak.
