The attitudes of students in ungraded primary and fourth grade classes toward educational-reform changes implemented in their classrooms were studied in Kentucky, using a sample of 53 students from the primary grades and 47 students from the fourth grade. Multi-age, multi-ability grouping, as experienced by these primary students, is a feature of changes under the Kentucky Educational Reform Act. These students were in a transitional phase, being involved in such groups for part of each day. Questionnaires requiring Likert-type responses were administered to these students. Responses suggest that students are accepting changes and seem to be adapting to teaching using the thematic approach, which emphasizes cooperative learning. Students in grade 4 preferred working by themselves more than the primary-grades group, though both groups accepted cooperative learning. Teachers are moving to more hands-on activities and are becoming more creative in the use of low-budget materials for projects. Two tables present student responses. (Contains 15 references.) (SLD)
