Teacher dons Iron Man mask to hide expression while grading

Aug. 24 (UPI) -- A university student in Malaysia revealed her teacher's unconventional way of hiding his facial expressions while grading -- donning an Iron Man mask.

Nur Izyan Farhani Binti Arifin, 18, a student at the International Islamic University in Malaysia, tweeted a pair of photos showing her teacher in a thinking skills class grading papers while wearing a mask modeled after the Marvel super hero.

"My lecturer wears mask to hide his expression so students wouldn't get nervous when hes giving marks," she tweeted.

The student said her teacher's mask does more than just hide his face, it broadcasts his fandom.

"He's also a big fan of Marvel and like Iron Man in particular," Izyan told Mashable.

She said some classmates appeared to have been made even more nervous by their teacher's artificial poker face.

"We were surprised of course, and most of us were taking pictures to post it online, like I did, but a few of them became nervous, saying it must be a bad sign or, even worse, a bad grade," Izyan said.
