Peer reviewedLesh, Richard A., Jr. – Journal for Research in Mathematics Education, 1976
This study examined the effectiveness of an organizer when used before versus after a unit of study. It also investigated the effects of type of unit (hierarchical or spiral organization) and students' ability level on the usefulness of advanced organizers. (SD)

Peer reviewedLesh, Richard A., Jr.; Johnson, Howard – Journal for Research in Mathematics Education, 1976
The effectiveness of four types of advanced organizers for a lesson on motion geometry was analyzed. The types of organizers were: (1) single application, (2) several applications, (3) single concrete model, (4) several concrete models. Results showed that advanced organizers can be effective under some conditions. (SD)
