Presents a stochastic model for distinguishing mental arithmetic errors according to causes of failure. A series of experiments (1) studied questions of goodness of fit and model validity among four and five year olds and (2) used the model to measure the relative contributions of developmental improvements in short-term memory and arithmetical…

Proposes five generalizations on existing knowledge, learning, and their interaction, and discusses evidence for these from recent research on children's learning, memory, conceptual understanding, and problem solving. (Author/AOS)

Relationships which exist between self-perception in science and cognitive development were explored under two quantitatively different teaching strategies: the use or nonuse of directions, praise, and rejection. A less directive teaching strategy appears to provide a more positive environment for developing an independent self-perception in…

Examined effects of operational levels of ninth-grade (N=16) and college (N=40) students on causal explanations they recalled after instruction. Results indicate concrete/formal students recalled explanations requiring chaining of two implication statements while formal subjects outperformed concrete subjects in reconstruction of complex…

The effects of different models of exploration questioning on young children's associative fluency were examined in two experiments with kindergarteners. It is concluded that asking descriptive and difference exploration questions are most facilitative of children's associative fluency. (Author/SEW)

This analysis synthesizes the research on characteristics of the mathematically gifted and describes some ways in which programs can be designed to address those characteristics. (MNS)

Concludes that cognitive development tasks may primarily evaluate reading readiness and suggests that proficient readers are particularly sensitive to semantic text cues. (FL)

Discusses the concept of egocentrism and its relation to cognitive development. Describes the major stages of egocentrism: sensori-motor, preoperational, concrete operational, and adolescent egocentrism. Focuses on research support for the theory of adolescent egocentrism. Discusses educational implications. (RC)

Examines the changes that occur from ages 5 to 11 in question/answer sequences of Dutch children. Function, content, form of questions, and listener response are analyzed. (EKN)

Examines how speakers and listeners make judgments on the relationship and truth of propositions connected by subordinating conjunctions. (EKN)

Investigated cognitive development of eleventh-grade students (N=389) in Jordan and its relationship to comprehension of concrete and formal physics concepts. Results revealed that cognitive level (17% formal; 52% concrete) was related to comprehension of both concrete and formal concepts. Findings related to sex differences are also reported.…

Describes a set of Science Reasoning Tasks which are valid and reliable for assessing the ability of children to use concrete and formal reasoning strategies and can be used by science teachers without professional training in Piagetian studies. Thirty pupils can be tested on each task in about 50 minutes. (Author/DS)

Describes the distinguishing features of a cult and the recruitment practices of cults on college campuses. Considers the psychological, social, and developmental reasons why students are attracted to cults, and describes the conversion process. Reports on campus policy, implications of litigation, and recommends strategies for dealing with cults.…

This article describes a summer program for high school graduates planning to enter college and major in mathematics, or natural or health sciences. The program is Piagetian-based and designed to assist the students in preparing for problem solving in college by providing multidisciplinary concrete experiences in science and mathematics. (SA)

Data on 140 eighth-grade earth science students were analyzed to see if logical thinking, instructional method, and the interaction between those two variables explained a significant portion of variance in achievement. Logical thinking was found to account for more variation in achievement than did treatment, although treatment also affected…
