Presents a method for initiating discovery learning in early childhood classrooms through the study of ants. Children read about ants, record observations, and conduct experiments. This method teaches children to explore the environment, organize activities, seek resources, and engage in scientific inquiry. Examples of children's work are…

A peer coaching program in Georgia involved 22 elementary teachers as participants in professional development to stimulate their cognitive development. Teachers learned the peer coaching process, then participated in four coaching cycles. The program raised their conceptual levels, reduced teacher isolation, and developed more positive attitudes…

Linguistic and cognitive development of 26 premature and 27 full-term infants was studied longitudinally over the first 3 years of life. Patterns of lexical and cognitive development did not differ substantially between groups, nor did standard language test measures indicate differences at the study's end except with very low birthweight…

The problems and possibilities that have arisen since the Key Stage 3 of the National Science Curriculum was implemented in the United Kingdom are discussed. The assessment strategies used with various attainment targets are described. The influence of the National Curriculum on testing is addressed. (KR)

Student comments about having time in class to think and solve problems are presented. Stressed are teaching methods which allow students to familiarize themselves with the problem, think about solution processes, work through the solution process, and reflect while solving a problem. (CW)

This paper provides a method for analyzing data consisting of event sequences and covariate observations associated with Markov chains. The objective is to use the covariate data to explain differences between individuals in the transition probability matrices characterizing their sequential data. (TJH)

The article focuses on the development of gifted behavior in children through nurturing the whole child, accommodating individual differences, and providing a wide range of educational experiences. A differentiated curriculum is recommended, which promotes higher cognitive processes, uses teaching strategies appropriate for able children, and…

Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill. Nonscientific beliefs discussed include special creation, orthogenesis, the soul, nonreductionism, vitalism, teleology, and nonemergentism. (KR)

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

Analyzing the paradigmatic shift from Peripatetic to Galilean physics can help to understand students' difficulties in learning Newtonian mechanics. Promotes the use of historical texts in physics teaching as a means to support students in becoming aware of the structural differences between everyday life and scientific views of the world.

Mismatch between gesture and speech was used to study cognitive processes that characterize the transition between incorrect, but rule-governed, problem understanding to correct rule-governed understanding among 90 fourth graders in Chicago (Illinois). Data support the idea that the transitional state is characterized by concurrent activation of…

Describes a competence/risk theory that hypothesizes that people can use personal competence to influence the probabilities of success or failure in an adventure, providing their perceptions are correct. In a series of linked pathways and feedback loops, a model illustrates the impact of a risk-taking activity on the participant's emotional and…

Assessed developments in the theory of mind suggested by changes in the organization of cognitive verb extensions during elementary school years. Found three major changes with development: increased understanding of the role of memory in input functions, increased interrelatedness of memory- and comprehension-related verbs, and increased…

Examined knowledge about medicines and perceived benefit among 101 children, ages 7 and 10. Found that medicine knowledge was explained using age, educational environment, and degree of internal locus of control as significant predictors. The negative effect of internal locus of control predicted perceived benefit. Retention of drug advertising…

Describes a variety of analytic tools available to address questions about development, including growth-curve methods, hierarchical regressions, and both primary and secondary data analysis of project and extant data. Demonstrates some of these techniques using extant data from two projects to examine questions about treatment efficacy and…
