Literature reviews dealing with psychotherapy and counseling too often conclude that no conclusions can be drawn. However, a critique of the literature on covert sensitization (CS) may offer clarifications of these apparently contradictory remarks. Research studies (N=84) were categorized by problem types, method used in the investigation, method…

The literature and typical approaches to reducing attrition among college students are critiqued, and a strategy for the identification of different interventions likely to have positive effects on retention rates of different student subgroups is proposed. It is claimed that a small sample approach to empirical testing of the combinations of…

Meant to study post secondary educational and vocational activities, the National Longitudinal Survey of the High School Class of 1972 (NLS) is reported to have consistently succeeded in overcoming diminishing response rates and sample attrition found in other longitudinal surveys.

Because chi square test comparisons of teacher…

In some educational research studies--particularly longitudinal studies requiring a probability sample of schools and spanning a wide range of grades--it is desirable to so select the sample that schools at different levels (e.g., elementary and secondary) "correspond." This has often proved unachievable, using standard methods of selecting school…

The use of games to introduce elementary school children to some concepts about environmental factors is described in this group of five documents.

Simple apparatus and experiments are suggested, and details of the…
