A furious teacher has been suspended after she threw textbooks around the classroom because her students had not done their homework in Thailand.
Khun Sudawan was checking the projects during a Thai language class but she became angry after finding out that most of the pupils had not finished their assignment on March 3.
As she was yelling at the teenage students - aged between 16 and 17 - some of the youngsters sitting at the back of the room began recording her.
Footage shows the Sudawan hurling the textbooks at the front of the class before walking up to a student and slapping him around the head with a book.
