Former pupil Verity Worthington spoke to Central News recently. She described Betty Yates as a teacher who 'brought real life to the classroom'.
During the trial Stephen Farrow exercised his right not to attend on some days, which the judge told the jury should not affect their verdict.
This says Verity is something she found difficult to accept.
Stephen Farrow displayed no emotion in court earlier as the jury returned their verdicts after spending eight-and-a-half hours' deliberation.
He stood silently as the judge told him he would spend the rest of his life in prison.

Mr Justice Field told Stephen Farrow at Bristol Crown Court today:
"On January 2 this year you somehow got into Betty Yates's home in the afternoon or early evening ...
"You struck Mrs Yates from behind with a heavy walking stick, hitting her hard at least twice to the back of the head with the rounded, bulbous handle.
"You hit her with such force that the walking stick splintered ...
"You then arranged her body and you put a pillow under her head.
"I am quite sure that having done that, you then inflicted the four stab wounds which you inflicted.
"You left the knife in the fatal wound - the wound that was going to bleed the most profusely."
David Yates, the son of murdered retired teacher Betty Yates spoke outside of court after Stephen Farrow received two life sentences for murder.
He said "we should all be relieved and thankful Farrow is off the streets of Britain today. As in his words that had he not been caught he would have continued to kill others and leave more misery in his wake."

Mrs Flellow has suffered nightmares since the loss of her friend.
The families of the retired teacher and vicar murdered by Stephen Farrow have said in a statement they "take some comfort from today's conviction but "nothing will compensate the families...for their losses."
"The sentence today reflectsd the brutal nature of these crimes and the devastating effect they had on the families of these victims".
