Although curiosity is an undeniably important aspect of children's cognitive development, a universally accepted operational definition of children's curiosity does not exist. Almost all of the research on measuring curiosity has focused on adults, and has used predominately questionnaire-type measures that are not appropriate for young children.…

The modern history of biology shows how Darwin's selectionist theory has replaced instructionist theories in explaining the operations of living things: first with inheritance through the gene pool of the 1850s, and second with the replacement of a template theory of immune system function in the 1960s. Today scholars in several disciplines…

This research was based on the assumption that the teaching of broadly generalizable cognitive skills should be a primary goal of education--that students can be taught to be better insight problem solvers outside of school by training in school and that they can be given the skills necessary for efficient discovery learning. The subjects were 116…

Reports two experiments in which eight patients with organic memory disorders exhibited a pattern of search behavior that resembled mnemonmic precedence--the ability to retrieve an object at an initial location, but not at a new location. (HOD)

Previous research on the relationship between age and creativity has shown that career age, rather than chronological age, correlates best with longitudinal changes in creative productivity. Recently, Dietrich (2004) proposed a new theoretical framework that integrates cognitive neuroscience with the findings of creativity research. By identifying…

This study investigates the development of an adaptive strategy for estimating numerosity from the theoretical perspective of strategic change. A simple estimation task was used. Participants of 3 different age groups (20 university students, 20 sixth-graders and 10 second-graders) had to estimate 100 numerosities of colored blocks presented in a…

This study was designed to determine students' abilities and difficulties in articulating the relationship between function and derivative. High-school students were presented 15 problems during two 75-minute interviews in which they were asked to construct functions experimentally in three different contexts: motion, fluids, and number-change. In…
