The aunt of a Prathom 1 (grade 1) student has agreed to delete a Facebook post showing how a maths teacher incorrectly marked her niece's homework after the school came clean and admitted the teacher's mistake.
Pennapa Saekow, 25, agreed to remove her post from Facebook after she and the child's parents met the director of Chumchon Wat Nong Tamlueng School in Chon Buri's Phan Thong district.
Chamnong Mingcharoen told them the assistant teacher, who made the mistake, had been careless by trying to mark homework too quickly.
The assistant teacher, who was not at the meeting, had agreed to change the way she marks course work, according to Mr Chamnong. The director said the teacher had also been under stress.
Ms Pennapa said she did not intend to humiliate the teacher when she decided to post the offending maths question on Facebook. She said she had meant to ask friends on Facebook for their opinion as to why her niece's answer was marked incorrect.
The maths question was: "Joy picked 12 mangoes while Jo picked eight more mangoes than Joy did. How many mangoes did Jo collect altogether?"
Ms Pennapa said she helped her niece figure out the answer to be 20. However, the assistant teacher wrote in the book that the correct answer was four.
She said the teacher's answer confused her niece who returned home with her homework book in which a red mark was scribbled and number "4" written next to it to show the "correct" answer.
Mr Chamnong said the teacher had misread the question and thought she needed to subtract 8 from 12, rather than add the numbers together.
Shortly after Ms Pennapa posted the question on her Facebook, it went viral and drew many responses, mostly critical of the teacher.
