Utilizing careful, empirical definitions of lesson kinetic structure, the authors tested two hypotheses: student content achievement is directly related to lesson content structure; and, awareness of commonality and theme development is directly related to lesson content structure. Student achievement seems to be related to communication…

Experiments showed that in verbal discrimination learning imaging the referent of the correct item was more facilitative than vocalizing the correct item, as long as the imagery structure was executed in the company of relevant motor activity. No difference between the two strategies was found in pictorial discrimination learning. (Author/BJG)

Efficiency was compared between three procedures for sequencing examples with minimal stimulus variation between adjacent positive and negative examples: dynamic, static, and static with maximal differences between pairs. For young children, increasing relevant feature saliency and altering a single stimulus to generate examples reduced training…

Processing requirements in letter discrimination for beginning readers with reflective-impulsive and field-dependent--field-independent learning styles were investigated. Results were interpreted in terms of feature analyses employed in letter identification and discrimination. (BJG)

Results lend partial support to the proposition that the effectiveness of a particular rehearsal strategy depends on the degree to which it provides a discriminative cue for the materials on hand: With homonym pairs, imagery constituted such a discriminative cue, while vocalization did not; with synonym pairs, the converse was true.

Results from the data analysis show that children learn mathematical concepts for clear cases, and that an analysis of attributes common to examples of a given concept is not a prerequisite to concept formation. The protocol findings provide information as to why this may be happening. (Author/PN)

The proposition was investigated that concept learning is a twofold process: acquisition of a prototype and development of generalization and discrimination skills. The assumption that formative evaluation procedures are necessary when attempting to prepare better instructional treatments for improved student performance was tested. (Author/GK)

Reproduction training improved performance only on the reproduction test; discrimination training improved performance only on the discrimination test. The effects of discrimination were seen both on forms used in training and on other similar forms, while the effects of reproduction training were seen only on trained forms. (Author/BJG)

Two training experiments were conducted to assess whether teaching grade 3 and 4 children to engage in comparison activity improves their referential communication performance (identifying a particular referent for a listerner) and message appraisal and production. Results demonstrated that comparison training improved childrens' referential…

In two studies with 50 male and 50 female undergraduates, differences in learning highly interfering paired-associate discrimination tasks were compared with or without visual mediational cues and with aural cues only. Visual mediational instruction reduced interference between similar signals and facilitated their association with the correct…

A study involving 110 fifth- and sixth-graders (51 male and 59 female), classified as low or high in effort orientation, assessed the effects of task- versus performance-oriented instructions on a computer-assisted test programed to ensure that all examinees failed to solve all problems. Problem-solving strategy analyses were preformed. (TJH)
