The school yard has been one of the least utilized of our educational resources. Surfaced with a view to his convenience and used mostly in accordance with his desires, it has practically belonged to the janitor. In the past 10 years the great play movement has burst upon us and has brought with it an illumination as to the educational value of play. The old-time school yard, with its limited space and its restrictive traditions, is entirely unsuited to the new uses demanded by the new ideals, and there is going on everywhere a reconstruction of theory and practice to meet the new needs. As in all reconstruction periods, however, the facilities and uses are out of harmony; and many cities, with an imperfect understanding of the problems involved, are attempting to improve conditions according to their lights. This bulletin discusses how to create a reorganized school playground. (Contains 1 footnote.) [Best copy available has been provided.]
