The college has been closed today in light of the news, with several students and staff taking the opportunity to grieve the loss.
Talking to ITV News Anglia, Khunakon Manmat said:
"I just heard this morning when I came to school and I was shocked.
"The first thing is she is very kind and she helped the students with anything if they had a problem.
"She's a nice lady and we're going to miss her now. I'm so sad."
A picture of the British woman killed in a plane crash in Kazan, Russia, yesterday has been released.
Donna Bull was described by colleagues at Bellerbys College as "a very popular and well-respected member of staff".
The widower of a British woman killed in a Russian plane crash said it was a "very difficult and emotional time" as her family tries to come to terms with the shock and loss.
Robert Crome said Donna Bull was "a wonderful mother" to her children George and Kate, and "kind, thoughtful and caring" to her friends and family".
He said in a statement today: "She was also a dedicated and hard-working professional, as a teacher and educationalist, so her students will all miss her greatly. Words are inadequate to express our grief and loss.
"We hope that the UK and Russian authorities can help to ease any administrative difficulties. We extend our heartfelt sympathies to all those families in Russia who too have lost their loved ones in this tragedy."
A college in Cambridge is closed today, as teachers and students grieve for a member of staff, who was killed in a Russian plane crash.
Donna Bull, who worked at Bellerbys College, flew to Moscow yesterday on a marketing trip.
She was among 50 people who died on a Boeing 727, as it tried to land at Kazan Airport last night.
Russian investigators are trying to determine why the crew of a plane that crashed at an airport were unable to land on the first attempt.
Alexander Poltinin, the head of the local branch of Russia's Investigative Committee, said they are looking at the possibility of pilot error or equipment failure.
The traffic controller at Kazan airport said the crew told him they were not ready for landing as it was approaching, but did not specify the problem.
One of the plane's two black boxes has been found, Mr Poltinin said, adding it could take weeks to identify some of the victims.
The British national killed when a Russian plane crashed while trying to land at an airport yesterday has been named as Cambridge woman Donna Bull.
Her employer, Bellerbys College in Cambridge, have described her as "a very popular and well-respected member of staff".
