Validity Typologies and the Logic and Practice of Quasi Experimentation.

Mark, Melvin M.

New Directions for Program Evaluation, n31 p47-66 Fall 1986

Several validity typologies are overviewed then integrated. The integrated framework is used to contrast the positions of Campbell and Cronback. The current practice and logic of quasi-experimentation is critiqued, and expansions beyond the primary focus of dominant validity typologies are suggested. (BS)
