This report summarizes the activities and findings of a focus group study of teachers' perceptions of the Montgomery County (Maryland) Public Schools instructional program in reading language arts and the instructional system in mathematics. Two groups were organized to provide information to the school program planners to help them in revising and refining the curricula. A total of 33 primary, 31 upper elementary, and 20 J/I/M (junior high/intermediate level/middle school level) teachers participated in the 8 focus groups (43 teachers discussed reading language arts, and 42 discussed the mathematics instructional system, with 4 groups of 8-12 participants discussing each of the areas). Questions addressed by the group concern problems that the curricula may have due to an overly prescriptive orientation, heavy demands on teacher time, and lack of support for teachers in the form of staff training and assistance and materials. Group findings for the two curriculum program cover teachers' perceptions of the overall program, planning, testing, administrative supports, recordkeeping, and collaboration. Copies of the focus group discussion guides and a discussion of the methodology for conducting the focus groups are appended. (TJH)
