Ordering theory was used in two studies to empirically determine hierarchies of developmental precedence for Piaget's 16 logical combinations. In study 1, subjects (N=94) responded to statements about odd and even numbers; in study 2, 30 subjects responded to statements about line segments. Results are reported and discussed. (Author/JN)

Word association techniques were used to examine the growth of biological knowledge over a period of years, from fourth-grade to college students. Results were analyzed by classifying stimulus-response word pairs according to the nature of the relationship between the words in each pair. Three hypotheses were tested: (1) the proportion of enactive…

Developmental differences in summaries of expository texts were examined for fourth and sixth grade students in two experiments. Experiment 1 used texts that had a description content structure whereas Experiment 2 texts had a thesis/evidence content structure. Manipulation of the presence or absence of the topic sentence allowed the examination…

Investigated spatial thinking abilities of sixth- and tenth-grade students from two locales--a school on the Navajo reservation and schools in Mesa, Arizona. Overall findings support the contention that there were no substantial time delays or advances in development of selected spatial abilities of Navajo students compared to parallel non-Indian…

Examples of explanations students give during science lessons are used to demonstrate that there are a number of very different modes of explaining. In addition, it is suggested that the peculiarly scientific method of explanation is fraught with difficulties, some of which current learning theories may just be able to describe. Areas discussed…

Data from 60 observations of 10 teachers and 10 each of their students showed that type/quality of teaching strategy predicted 37 percent of variance in engagement and that the more indirect the teaching strategy, the greater the students' involvement in learning tasks. Implications of these and other findings are discussed. (Author/JN)

The study with three profoundly deaf subjects (ages 11-13) investigated whether there is a chain of functional relationships among a method of interaction referred to as a mediation, a cognitive function referred to as spontaneous comparative behavior, the operation of categorization, and the reading comprehension tasks of using lexical cohesion…

Researchers have attempted to develop paper and pencil Piagetian tests that yield results equivalent to manipulative Piagetian tasks and that can be administered in significantly less time. This study is an attempt to partially replicate and extend the findings of research by Paul Ankeny and Lyle Joyce who found significant positive correlations…

The present study was designed to identify parent-child interaction patterns that might differentiate bright from below average elementary students in order to test the hypothesis that environmental processes related to regulation of executive processes influence both children's learning and developmental level. Thirty-two mother-child dyads (16…

In this study of 40 fourth graders and two teachers, the influence teacher ideological differences have on how children learn to write during classroom lessons was investigated. Analysis of narrative compositions based on a picture sequence revealed significant differences between student compositions for an academic teacher and a…

The purpose of this study was to investigate the effect of an eclectic thinking processes model on the logical reasoning abilities of students in grades six through twelve. The experimental school consisted of 159 students whereas the control school had 111 students. The Group Assessment of Logical Thinking (GALT) was administered to the sample as…

This study compared the use by 6 gifted and 6 nongifted students (ages 10 and 11) of a software package designed to develop cognitive control strategies. Bright students more often used a plan in their strategy, offered suggestions for improving the software, and monitored their own performance. (Author/DB)

Intervention to enhance Interpersonal Cognitive Problem Solving (ICPS) skills has been shown to significantly reduce observable negative, impulsive and inhibited behaviors and increase positive qualities in young, low socioeconomic status (SES) children. An ICPS model for older children was implemented with 202 low SES fifth graders to test…

This experiment explored how incorporating the importance of task strategy use and positive achievement beliefs into cognitive modeling affected self-efficacy and skill acquisition. Students deficient in division skills received cognitive modeling of division solution strategies and practice opportunities. For one group of students the cognitive…

This practicum was designed to incorporate critical thinking skills instruction and practice into a fourth-grade curriculum to increase fourth-grade students' ability to recognize and apply critical thinking strategies to appropriate situations. This program concentrated on the increasing of six critical thinking skills: classification, sequence…
