The main objective of this study is to determine whether boys and girls learn better when the characteristics of the pedagogical agent are matched to the gender of the learner while learning in immersive virtual reality (VR). Sixty-six middle school students (33 females) were randomly assigned to learn about laboratory safety with one of two…

The question of which aspects of a problem are hard to remember is addressed. A series of studies assessing the difficulty of representing various kinds of algebraic information in memory are presented. (Author/GK)

In three experiments, subjects listened to a taped lecture on the topic of exposure meters for 35-mm cameras and were tested after one, two, or three presentations. Results suggest that repetition produces both a quantitative increase in amount learned and a qualitative change in the reader's processing strategy. (Author/LMO)

In two experiments, high school students read and listened to either a signaled or nonsignaled expository passage. Signals consisted of preview sentences, underlined headings, and logical connective phrases. Results indicated a pattern in which the signaled groups performed better on recall of conceptual information and on generating high quality…

Subjects listened to a short science passage one, two, or three times. Overall amount recalled increased with number of presentations, but recall of conceptual principles and related information increased sharply with repetition, whereas recall of formal equations and concrete analogies did not. Advance organizers functioned similarly. (Author/PN)

This study concerns the role of structural properties of scientific prose: description of relations and explanation of mechanisms. The latter is isolated as a characteristics related to creative problem solving. (Author/GK)

Subjects read a text concerning a new computer programing language, with an advance organizer given either before or after reading. On a recall test, there were different patterns of performance. Results suggested that the locus of the effect was at encoding rather than retrieval. (Author/GDC)

In a series of five experiments, novices read a text on computer programming, and engaged in one of the following learning strategies: advance organizer, model elaboration, comparative elaboration, normal reading (control). Results of transfer tests indicated a pattern in which the treatment groups excelled on the ability to put the information…

In five experiments, novices read a computer programing text and engaged in one of these learning strategies: advance organizer, model elaboration, comparative elaboration, normal reading. Results of transfer and recall tests suggested that elaboration techniques can be applied to "real-world" materials, resulting in more integrated…

This review of ideas from cognitive and educational psychology that are related to the problem of how to teach non-programmers to use computers explores two techniques. The first one discussed is the effects of concrete models on people's understanding and learning of new technical information such as computer programming. Research results provide…

In four experiments involving 357 undergraduates, students who read expository passages with seductive details (interesting but irrelevant details) recalled fewer main ideas and generated fewer problem-solving transfer solutions than those who read passages without seductive details. Results suggest that seductive details may prime inappropriate…

These experiments tested the hypothesis that an instructional strategy involving guided discovery will promote meaningful learning of problem solving concepts by activating an assimilative set during learning. In order to investigate the effect of discovery training and concrete manipulation, preschool children were given training in one to one…

The effects of advance organizers in learning unfamiliar material from logical or randomly organized texts was investigated in two experiments. Advance organizers enhanced performance on questions requiring integration of facts from different sections of the text. Results of both studies were interpreted as support for assimilation encoding…

In 3 experiments, 163 college students who read a summary with a sequence of short captions with simple illustrations depicting steps in a process recalled the steps and solved transfer problems as well as or better than students who received the full text with a summary or alone. (SLD)

Subjects in the first part of this two-part study (56 undergraduates) read a 24-frame text on computer programming that was presented either in logical or in random order. The results of this experiment showed that the subjects given an advance organizer in the random order presentation performed better on a posttest than did control subjects (no…
