The "control" group consisted of 64 children who had been eligible for a Head Start program. They roughly matched a group of Head Start (HS) children in IQ scores, age, and…

Rozran, Gilbert B. – 1968
This project utilized computer-based instruction proven effective in military training programs, cue-response programing, "SNAP" programed texts, and programed overlays for the "SMART" trainer (a universal simulation and representation devide which can be tailored to a specific course merely by changing the students' panel and…

The Perry Preschool Project in Ypsilanti, Michigan, is structured so that a group of disadvantaged 3-year-old Negro children begin a 2-year preschool program each year. The program was originally very verbal-learning oriented but has recently been modified to make use of Piaget's cognitive development theories. From the beginning of the program…

Hunt, Thomas C.; Weber, Larry J. – 1969
Increased student demand for foundations courses, coupled with a lack of qualified staff, made it necessary to provide workable alternatives to traditional instruction. Substantial adjustments could not be made until the efficacy of the new methods could be documented. The study compared cognitive and attitudinal outcomes of two types of classes,…

Roberts, Julian – 1973
Most studies either concentrate on situational variants or relate specifically to differences in interpersonal relationships involved. Therefore, difficulties arise in setting up control groups, the timing of post-measurements, and the use of varied intervention techniques. Dilemmas are caused by focusing on projected, rather than on desired,…
