With her sister Edna Dean Baker, Baker co-founded Baker Demonstration School and served as its director for many years.
Baker promoted the modernization of children's reading education;[5][6][7] she was the author of many readers and other curricular materials for elementary students.[8][9][10][11][12]
In 1921, Baker published Songs for the little child, a mixture of her own compositions and various folk songs, with music by Caroline Kohlsaat.[13][14] The book was released through twelve editions and as of 2019 is still held by more than 100 libraries.[15][8] She later collaborated with William H. Burton to produce the document Reading in Child Development.[16]
