This article focuses on three single case methodologies: psychohistory, case study, and intensive experimental design. The influence of the holistic perspective is discussed.…

The authors review nineteen evaluations and reports dealing with alternative schools, examining the structure of the research, findings, and recommendations. In an examination of the research methodology, weaknesses are described and suggestions for improving the quality of future research are made. (MJB)

The activities of a research working group are described. The investigators from several institutions coordinate their work on space and geometry. Underlying assumptions of the group and issues faced by it are described. (SD)

It is argued that research settings should be chosen with the whole experimental design in mind and that the availability of appropriate controls (groups or occasions for observation) should be as important as the suitability of the treatment group. (Author/AM)
