Procedural understanding should be taught to students for an understanding of the 'nature of science'. Considers some of the concepts of evidence that are particularly important to biology, and discusses how and why these ideas could be taught. (Contains 21 references.) (Author/YDS)

Trained 3-, 5-, and 8-year-olds in temporal bisection task, with nonstandard comparison stimuli spaced linearly between short or long standard visual stimuli. Statistical analyses and results from different theoretical models of the data all suggested that temporal sensitivity was higher in the 8-year-olds than in younger groups, even when the…

Two experiments examined relation between age-related changes in retention and age-related changes in the misinformation effect. Found large age-related retention differences when participants were interviewed immediately and after 1 day, but after 6 weeks, differences were minimal. Exposure to misleading information increased commission errors.…

Analysis of course videos of 11 instructors of agricultural distance education courses showed their instruction achieved objectives for lower-level cognition (remembering, processing) but not higher-level outcomes (creating, evaluating). The cognition level of Iowa Communications Network courses was higher than those delivered by other distance…

Assessed the relationship between temporally distant antecedent events (TDEs) and the frequency and function of aggressive and out-of-seat behaviors occurring in school. Results were consistent with previous literature that describes certain antecedent events as establishing operations. Discussion includes how these events interact to alter the…

Infants' abilities to identify objects based on their perceptual features develop gradually during the first year and possibly beyond. Earlier we reported [Kaldy, Z., & Leslie, A. M. (2003). Identification of objects in 9-month-old infants: Integrating "what" and "where" information. Developmental Science, 6, 360-373] that infants at 9 months of…

Young children in poor communities are spending more hours in nonparental care because of policy reforms and expansion of early childhood programs. Studies show positive effects of high-quality center-based care on children's cognitive growth. Yet, little is known about the effects of center care typically available in poor communities or the…

A large literature has documented the influence of child care on young children's development, but few studies have examined low-income children in community care arrangements. Using data from Welfare, Children, and Families: A Three-City Study (N=204), this study examined the influence of child care quality and the extent of care on low-income…

Children's drawings are thought to be a mirror of a child's representational development. Research suggests that with age children develop more complex and symbolic representational strategies and reference points become more differentiated by gender. We collected two drawings from 109 5-13-year-old children (three age groups). Each child drew…

Children from seven classes representing the year groups in a primary school were interviewed in groups of three or four to find out their understanding and views on issues related to the environment and science. The large majority showed considerable interest and concern about environmental issues related to their experience and understanding,…

Niels Bohr's term "complementarity" has been used by several authors to capture the essential aspects of the cognitive and epistemological development of scientific and mathematical concepts. In this paper we will conceive of complementarity in terms of the dual notions of extension and intension of mathematical terms. A complementarist approach…

This study examined the effect of exemplar typicality on reaction time and accuracy of categorization. High-functioning children (age 9-12), adolescents (age 13-16), and adults with autism (age 17-48) and matched controls were tested in a category verification procedure. All groups showed improved processing throughout the lifespan for typical and…

Language, as is known, is acquired under certain conditions: rapid and sequential brain maturation and cognitive development, the need to exchange information and to control others' actions, and an exposure to appropriate speech input. This research aims at analyzing preschoolers' overgeneralizations of the object labeling process in different…

We explored how relational complexity and featural distraction, as varied in scene analogy problems, affect children's analogical reasoning performance. Results with 3- and 4-year-olds, 6- and 7-year-olds, 9- to 11-year-olds, and 13- and 14-year-olds indicate that when children can identify the critical structural relations in a scene analogy…

During birth to 2 years, babies are motivated by an innate need to know about things. At 3 to 4 years, children tend to wonder about a lot of things. They wonder about scary things, how things work, nature, origins, and the world around them. At 5 to 6 years, they tend to increase their awareness, observe and notice a lot of differences. The…
