This article reconsiders Case's theory of central conceptual structures (CCS), examining the relation between working memory and the acquisition of quantitative CCS. The lead hypothesis is that the development of working memory capacity shapes the development of quantitative concepts (whole and rational numbers). Study I, with 779 children from…

Working memory is the retention of a small amount of information in a readily accessible form. It facilitates planning, comprehension, reasoning, and problem solving. I examine the historical roots and conceptual development of the concept and the theoretical and practical implications of current debates about working memory mechanisms. Then, I…

Purpose: As online learning has become more prevalent, how learners interact with each other in those learning environments has become more salient. To develop effective levels of interaction, students must feel comfortable to express their ideas and views. For this reason, this paper aims to look at how individual students' levels of social…

In this paper it is proposed that the prefrontal lobe participates in two closely related but different executive function abilities: (1) "metacognitive executive functions": problem solving, planning, concept formation, strategy development and implementation, controlling attention, working memory, and the like; that is, executive functions as…

The current study was devised to determine the short-term (1 month) and long-term (4 months) effects of having students generate their own examples of selected concepts. More specifically, focus was on determining how self-generated examples might enhance the learning and retrieval of concepts. Subjects were 55 (54 female and 1 male) undergraduate…

Children (ages 9 and 14) with mild mental retardation and matched controls without mental retardation were given a test of their ability to perceive relations among different stimuli and transfer learned behavior from familiar to less familiar environments. Results showed that subjects with retardation relied only on prototype information, whereas…
