This report presents the problem and a solution to the treatment of students by age interactions. It considers the plight of an educational researcher who wishes to demonstrate that a particular treatment effect changes from age to age. In analysis of variance language, he is seeking a treatment by age interaction. The report presents a rationale…

Attempts to identify specific components of a complex associative task, foreign language vocabulary learning, that might be particularly sensitive to developmental differences in imagery generation ability. Subjects were 95 second grade children enrolled in four schools and 90 sixth grade children enrolled in two of these same schools. (Author/MP)

A total of 96 first graders, fifth graders, and college students were asked to predict how many orally presented nouns they would later be able to recall or recognize. Results showed large developmental differences in prediction accuracy on the recall but not on the recognition tasks. (Author/JMB)

Two experiments investigated the role of children's spontaneous conceptual "biases" in pictorial discrimination learning. The results suggested that such biases may serve either to facilitate or to interfere with discrimination learning. Moreover, in each experiment, age by treatment interactions revealed that in comparison to the behavior of…

To test the comparative efficacy of a visual imagery associative learning strategy in younger and older children, second and sixth grade children were presented a list of paired associates (concrete nouns) either at a faster or slower rate, under either an instruction to generate an interactive image for the pairs or a no strategy, control…

Six investigations of the keyword method of foreign language vocabulary learning were conducted to evaluate differences found in highly structured laboratory-like settings. Two experiments produced keyword effects when the method was administered to small or classroom-sized groups of elementary school children. (Author/RD)

In this study, the self-reported strategies of fifth, seventh, and ninth grade subjects used to learn a list of paired associates were correlated with actual learning performance to test the hypothesis that proficient learners are elaborators. (Author/SB)
