Mrs. Helen Heffernan, who was the Elementary Schools Officer prepared a proposed outline for the Language Arts Course of Study, 3 June 1947. She recommended that subcommittee be set up prepare the materials for primary grade, Intermediate grade, and Junior high school. In this paper I examined two Japanese documents, The former is after 3 June 1947., and the latter was 24 June 1947. The Language Arts Course of Study (1947) was completed thanks to Helen Heffernan and Japanese stuff. The Language Arts Course of Study (1947) was made in the short period of two months.
