The one room school is a challenging educational setting for both teacher and student. Isolation of the school, limited availability of educational resources, and the demanding role of the school as the only formal educational institution within the community are conditions which make classroom efficiency an important consideration for the principal/teacher. Four principles which relate to classroom efficiency can be applied to most situations: (1) the efficient classroom is a center of learning activities; (2) an efficient classroom is supported by one or more storage rooms; (3) the use of learning centers is an efficient method of organizing classroom resources; and (4) the efficient classroom is in a state of flux. Five steps can be followed to create an efficient classroom. First, draw a diagram of the classroom in its present arrangement. Second, mark stored materials not actively used in learning activities with red X's and materials blocking chalkboards or degrading learning options with blue X's. Next, list the specific learning activities to take place in the classroom. Then make a new diagram to facilitate these learning activities. Finally, rearrange the room according to the new design, being careful to keep materials not presently needed neatly organized in the support/store room. (NEC)
