It is the Australian primary school science lab where a Nobel Prize-winning scientist runs workshops with nine-year-olds and 3D printers turn children's designs into holographics. Now the man behind it all, Australian teacher 60-year-old Richard Johnson (pictured), of Rostrata Primary School, Perth, has less than a day left before he finds out if he has won the world's richest school education award, the $1 million Global Teacher Prize. One of a field of 10, Mr Johnson's face and those of his competitors have been plastered across the walls of Dubai's palatial Atlantis Hotel, taken over by a profession that has been desperately trying to boost its status in Australia and abroad. In   February, Stephen Hawking announced the finalists. Hollywood stars Matthew McConaughey and Salma Hayek will present the awards as 22 education ministers and three former heads of state take their seats in the audience on Monday morning. But organisers don't want you to pay any attention to them. It's about teachers like Mr Johnson, who forged his way to the top of classroom science from a general primary teaching position more than two decades ago.
