Langevin taught and wrote about art and art education.[3] In 1951 she wrote a series of reports about arts education in France for UNESCO.[4] In 1960, she was an adjudicator for folk dance competitions at the Llangollen International Eisteddfod.[5]
Langevin was known for her explorations of "collective paintings", murals painted by a group, often as a classroom or community activity.[6] An American textbook explained the process Langevin taught: "The members of the class produce small paintings. One painting is selected and divided into squares which are numbered. Each child in the class is assigned one square which he copies on a large scale on another piece of paper. Eventually the large squares are assembled to form a very large picture."[7]Le roi et la reine and Le cheval de Troie, paintings created this way, in a classroom under Langevin and Jean Lombard's supervision, are in the collection of the Centre Pompidou.[8][9]
