Ms Marshall-Plewes has died while swimming in the sea on holiday in the Dominican Republic.
Ms Marshall-Plewes, 36, drowned in the luxury holiday resort during the early hours of Saturday morning.
She was an English teacher at the Priory City of Lincoln Academy, in Skellingthorpe Road. She lived on Birchwood estate.
Former student Danielle Jenkinson, 19, told the Echo.
"She was more of a friend and a mother figure than a teacher.
"As pupils we could go to her about anything and everything. That could include any problems outside of school.
"She was the most amazing person and a brilliant teacher.
"She had a fish bowl in her classroom at school and we used to feed the fish every time we started class.
"I will always remember her and everyone will miss her."
Former student Craig Clark said: “Loved English classes with her. They were awesome.”
