Volume II is a compendium of the major existing literature that (1) describes the activities performed in educational RDD&E; and (2) presents the frameworks or models that have been used to define, describe, differentiate, and relate educational RDD&E. The volume serves as a basic literature source for the design and implementation of new training programs to prepare persons for the emerging disciplines of development, diffusion, and evaluation in the field of education. As part of the Oregon Studies, it also served as a basic literature source for the preparation of conceptual frameworks viewing the domain of educational RDD&E (Volume III) and for the development of the "case study" data-gathering methodology (Volume V). This part (Part 2) of Volume II contains 15 articles that deal with diffusion and a balance of 26 articles that are distributed across various combinations of RDD&E. Related documents are EA 004 582-583 and EA 004 585-589. (Author/JH)
