Schramm, Wilbur – 1971
Instructional cross-media experiments are difficult to design because they involve complex instructional systems which include variables that are hard to control. Strict controls can be approached in the laboratory setting, but as the experimenter moves from the laboratory to the field study, especially in developing countries, concessions to…

Gladkowski, Gerald – 1973
The purpose of this paper is twofold: (1) to indicate some of the major weaknesses in the design and approaches to compensatory education programs, and (2) to recommend a more appropriate evaluational design. The second purpose deals specifically with a recommended evaluational procedure; i.e., the discussion centers around an account of what…

Lunneborg, Clifford E. – 1971
A Bayesian prediction strategy is outlined in which antecedent measures are divided into two subgroups. One subgroup is used to discriminate among criterion groups, the second to provide normal linear predictions for each group. Individualized regression constants are subsequently obtained by computing probabilities of group membership from the…

Ramey, Craig T.; Haskins, Ron – Intelligence, 1981
Infants judged to be at risk for subnormal intellectual growth were randomly assigned to experimental and control groups which varied as to educational curriculum activities. Two types of evidence, group differences and parent-child IQ correlations, demonstrate the importance of early environments in intellectual development. (Author/RD)
