退休教师自录视频向学生授课   2014-09-10

 

FOR retired mathematics teacher Xu Yonghai, teaching never stops.

The 74-year-old Xu, who retired from Shanghai High School in 1999, has produced and uploaded 81 teaching videos on the Internet that are benefitting children from the mountainous areas of China. The videos carry the essence of his 50 years of his teaching experience.

Soon after retirement, Xu picked up a job as a private math tutor, but it did not interest him for long. He volunteered to teach at the Libo High School in Guizhou Province from 2007.
