The blending of technology with teaching has permitted the introduction of individualized instruction for the total student body at Marshall High School, Portland, Oregon. In conjunction with the School of Education at Stanford University, a computerized modular-flexible schedule was made operational and put to use in September 1963. Prior to implementation, experimental teaching techniques such as team teaching were undertaken, and inservice training workshops for Marshall staff members were used to prepare for the new instructional program. When the program was implemented, the basic schedule was changed from the conventional seven-period day to one divided into 21 20-minute modules. Students, with advisory help, preregister in the spring for the following year. With these student schedules, a master plan is prepared with the use of a computer. Flexibility is permitted by use of four teaching-learning modes--large group instruction, medium-size groups for laboratory activities, small group learning experiences, and independent study. (LN)
