Evolution of public educational facilities in the United States was reviewed for three distinct periods of school architecture: the Agricultural Period (16501849), Industrial Period (18501949), and the Information Period (19501999). Of these periods identified in the review of literature, schools surveyed were originally constructed during the Industrial and Information periods. The purpose of this study was to determine if historic schools (built before 1956) and modern schools (built after 1985) followed the principles of school facilities from Chapter II in Barnards School Architecture (1848). The survey included 12 research questions categorized under the headings of Architectural, Classroom, and Resources for Instructor. The sample of the study included ten historic and ten modern schools paired for comparison in the areas of: Minimum airspace per student. Ease of movement for students in classroom. Unrestricted movement for students in seats. Ease of observation of students and movement for teacher in individual classrooms. The finding of individual pairs of modern and historic schools revealed each set surveyed in Northeast Georgia did conform to the standards set fourth by Barnard. In the final analysis every school surveyed was found to comply with the principals set fourth in 1848. The modern classrooms were significantly larger in square footage per student, but not in cubic feet of airspace, yet for each of these criteria these schools did comply with Barnards criteria.
