Paragraph 1
A university professor in Singapore gave a two-hour
lecture but didn't realize he was on
. Professor Wang, who teaches
, was not aware that throughout his online presentation, the
on his computer was switched off. This meant that
of the students attending his online class heard what professor Wang was talking about. His university switched his classes
to help reduce the
of COVID-19. His lecture started well but
it froze. The video came back but the
was off and professor Wang did not notice. One of his students says it might have been
the professor was using an iPad and not a computer.
