Baptist University professor Henry Mok Tai-kee, accused by students of neglecting teaching duties, admitted last night he did sing in lectures and was late for classes.
But the suspended head of the social work department said the singing was part of his teaching to create a 'better and more relaxed' atmosphere. The practice was common in universities overseas, he said.
'I have published over 20 books in the past and I do need to sing for 45 minutes in classes,' he said.
Dr Mok said he was only late for class 'on some occasions', and pledged to donate a $100 book coupon to students for each minute he arrived late in future.
He also rejected claims that he had encouraged students to commit suicide, saying the allegation was 'exaggerated and quoted out of context'.
The professor said the complaints might have been caused by students feeling pressured by his tough academic standards.
