This document describes the variable student scheduling program at Arapahoe High School in Littleton, a suburb of Denver, Colorado. Under this plan students have Monday-Wednesday-Friday classes and Tuesday-Thursday classes of approximately one hour. Four- and five-day-a-week classes are also scheduled. The program is now in its third year of operation. The program was instituted to help broaden the scope of the curriculum, to give students and teachers more time for preparation and interaction, to give students greater opportunity for decisionmaking, and to allow teachers to experiment with new teaching techniques. Under the program the number of course offerings increased from approximately 100 to approximately 250, and resource centers for students and teachers have been created. The document lists the advantages and disadvantages of the program and describes how the program was implemented. (Author/DN)
