Describes children's conceptions of the structure and function of the human digestive system based on an investigation carried out with children aged 4-10 (n=45). Finds that children possess biological knowledge as an independent knowledge domain from the age of four. Discusses acquisition of and barriers to scientific concepts related to human…

Examines how mothers deviate from text while reading to young children and how these deviations vary according to children's development based on chronological age. Tests 25 mothers. Shows mothers of 24-month-olds and 4-year-olds asked more questions to engage their children, whereas mothers of younger children simplified text concepts. (PA)

Children lacking sufficient mediated learning experiences (MLEs) are ill-prepared to handle the cognitive challenges confronting them at school and cannot benefit even from hands-on learning experiences. Reuven Feuerstein's theory of MLE holds that our cognitive abilities are modifiable, that we can change the course of a child's early cognitive…

Presented five- and eight-month olds with silent moving and static video images of self, peer, and doll, and sounds of self and nonsocial objects. Found that recognition of one's image develops through experience with dynamic facial stimulation during first eight months. By five months, infants treat their faces and voices as familiar and social…

Two experiments examined role of affective correspondence between signal and outcome in 4-month olds' associative learning. Found that only when consoling infant-directed speech signaled the sad face did infants' visual interest in a checkerboard increase. Arousing infant-directed speech signaling either the smiling or sad face produced positive…

Proposes preliminary guidelines applicable to the creation of hypermedia-based learning environments that draw on insights gained from research in a number of fields. The framework encompasses (1) the importance of modern pedagogy in shaping instructional design, (2) cognitive and instructional design factors that may facilitate development of…

Focuses on whether teachers' enabling styles in talking with young pupils depends on supportive strategies on teacher's part or whether any more specific teacher discourse-moves can be identified as productive. Analyzes one extended recording in which the teacher talks with a group of 5-year olds for approximately 30 minutes. Conclusions are drawn…

Bloom's taxonomy suggests that the learning process moves hierarchically, from simple to complex, in both the cognitive and affective domains. Spanish curriculum typically emphasizes the cognitive over the affective domain. However, the two domains appear to be interrelated. Spanish FLES programs could be enhanced by emphasizing the learning…

Introduces this special journal issue by describing what developmental approaches are and how they can be applied to children with disabilities. Gives a short preview of the articles in the issue and raises future challenges for developmental research and intervention with young children with disabilities. (JS)

Demonstrates the use of Rasch models to assess the dimensionality of an item set across cohorts in longitudinal studies. Presents data from a study on adolescents' deductive reasoning ability showing that the same test items can be measuring qualitatively different latent traits in different subsamples or at different time points. (JPB)

Draws upon the metaphor of "apprenticeship" to explain how individual cognitive development of children and adults alike can be enhanced by mentoring relationships within a particular educational "culture." Proposes that computers and related technologies can be instrumental in creating socially interactive and reflective learning communities.…

Three experiments explored change toward more flexible reliance on combinations of spatial and nonspatial landmark information to reorient oneself. Identified 5-7 years as age for this developmental change. Results suggest that language production skills play a causal role in allowing humans to construct novel representations rapidly, which can…

This paper answers several frequently asked questions about constructivism, including how to define it, how to plan the curriculum, how to assess student understanding, what to do with the information, where to begin, how students work in a constructivist classroom, and why constructivism is important. (SM)

Devised a model that hypothesized that students, in discriminating relevant information in mathematical story problems, search for values of semantic categories that match those in the problem. Two experiments assessed the validity of the model. Results indicated that the model was an accurate predictor of discrimination performance for successful…

Analyzes group discourse (n=24) during laboratory investigations in order to understand how students solve scientific problems and the ways social roles shape the development and articulation of arguments. Results indicate that knowledge building depends on students learning to use tools of the scientific community and the social context in which…
