Rowland left that industry to pursue a career as a textbook Writer. For several years she was involved in writing and publishing children's textbooks. She was also the publisher of the Children's Magazine Guide. In the 1970s, Rowland created a comprehensive language arts program, called Beginning to Read, Write, and Listen. It was informally known as the "letterbooks", and designed to be used for kindergarten and first grade students. Through the years the program has undergone several revisions and updates.
