How different are the concepts held by children who grow up in a North American middle class neighborhood and by children who grow up in a rural Malagasy fishing village? By probing Malagasy children's and adults' conceptual representations of human and animal kind, biological inheritance, innate potential and family relations, the studies presented in this Monograph address current debates about the acquisition and the nature of concepts in the domains of folkbiology and folksociology. Cross-cultural and developmental studies of this kind bear on the hypothesis that conceptual development in these domains is supported and constrained by innate conceptual content. If so, one would expect cross-cultural universality in the relevant adult concepts and their early emergence in childhood regardless of widely different input conditions. We chose to conduct these studies among the Vezo of Madagascar because the ethnographic literature has attributed to them folkbiological and folksociological theories that are radically different, even in commensurable, with those of North American adults. Vezo therefore provide a challenging test for the innate conceptual constraints hypothesis.Four studies probed aspects of biological and sociological reasoning of Vezo children, adolescents and adults through a number of adoption scenarios. Despite ethnographic reports to the contrary, we found cross-cultural convergence in adult concepts of biological inheritance, but the pattern of development of this concept differed greatly from that seen in North America. Moreover, in agreement with the ethnographic literature, we found that Vezo adults have constructed a distinctive theory of social group identity. However, we found that children's reasoning in this domain is under the influence of endogenous constraints that are overturned in the course of development. Finally, we found cross-cultural convergence in adults' concept of species kind, as well as evidence for the early emergence of this concept. In light of these findings, we discuss the nature of the constraints on children's conceptual representations, the developmental process through which the adults' concepts are constructed, and relations between Vezotheories of folkbiology and folksociology. 相似文献

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

Children living in out-of-home care have experienced a multitude of adversities, often resulting in compromised functioning. The current study used Ontario Looking After Children (OnLAC) project data to estimate developmental trajectories of behavioral outcomes (i.e., conduct and emotional problems) over a 4-year period (i.e., ages 6–10 to 9–13) in 313 children living in out-of-home care. Predictors measured at baseline (e.g., sex) and across the subsequent 4-year period (e.g., parenting practices) were also investigated. Findings indicated that 64.2% and 58.6% followed resilient trajectories for conduct behaviors and emotional functioning, respectively. Predictors of resilient trajectories included internal developmental assets, number of children in the home, whether the child was receiving treatment, and positive parenting. Findings need to be interpreted with an understanding that children in out-of-home care have varying levels of functioning across various domains (e.g., educational, social) other than the ones measured here. Predictors were static and dynamic and cut across various contexts, emphasizing the importance of considering child functioning within an ecological model. 相似文献

Research Findings: An emerging consensus is that casual, direct contact with nature influences the development of children’s biological knowledge. Here we review the existing literature on this topic, focusing on the effects of (a) rural versus urban rearing environments and (b) pet ownership and care on children’s biological concepts and reasoning. Although the research is limited, the evidence suggests that these factors positively influence children’s understanding of specific biological phenomena (e.g., internal organ function, biological inheritance) and reasoning patterns (e.g., anthropocentrism, ecological reasoning). Practice or Policy: In the modern context of diminishing outdoor playtime and limited experience with nature, this review highlights the importance of direct exposure to the natural world for children’s conceptual development in the domain of biology. 相似文献

Understanding Natural Cause: Children''s Explanations of How Objects and Their Properties Originate 总被引：1，自引：0，他引：1
An understanding of natural cause includes the realization that events can occur independently of human activity or intentions. It also often entails realizing that causal mechanisms can be nonobservable or nonobvious. The present research investigated to what extent children ages 4-7 have developed a concept of natural cause. Study 1 examined children's understandings of object origins (e.g., how the sun began); Study 2 probed children's causal understandings of object behaviors and properties (e.g., why rabbits hop and have long ears). In both studies, children by age 4 were sensitive to the natural kind-artifact distinction in their explanations. They mentioned human intervention for human-made artifacts but rarely for naturally occurring things. Moreover, subjects at all ages were able to identify specific kinds of natural cause, including intrinsic causes (such as growth) and inborn nature. Finally, subjects understood the link between nonobvious, internal parts and self-generated activity (e.g., that bones are important for the flight of a bird). Altogether, these results suggest that even preschool children realize that natural causes exist. They contradict Piaget's characterization of young children as artificialistic (believing that naturally occurring things are created by people) and as focused on observable properties. 相似文献

The role of analogies in promoting conceptual change in biology 总被引：1，自引：0，他引：1
Four analogies which were used to teach biology topics by four different teachers were analysed from different theoretical perspectives to determine the key role they had to play in the process of conceptual change. A supermarket analogy for the classification of living things was described using the Posner et al. (1982) view of conceptual change as having the role of a sense maker. A car cooling system analogy for human temperature homeostasis was found to play the role of a memory aid and was best explained by considering Vosniadou's (1994) framework theory and mental models perspective of conceptual change. A fluid mosaic analogy for cell membranes was used by the teacher as a transformer and was best explained by Chi et al.'s (1994) ontological category perspective of conceptual change. Finally, a bucket and pump analogy used to teach the stucture and function of the heart was described as a motivator and was viewed through the motivational perspective of conceptual change of Pintrich et al. (1993). The paper concludes that learning in different situations can best be explained by different perspectives of conceptual change and that these perspectives have much to tell us about the normal shifts in conceptual understanding as well as radical conceptual change. 相似文献

Children''s and Adults'' Models for Predicting Teleological Action: The Development of a Biology-Based Model 总被引：2，自引：0，他引：2
Understanding that only living things must act to gain self-beneficial goals is important for developing a theory-like understanding of the living world. This research studied the models that preschoolers, fifth graders, and adults use to guide their predictions of self-beneficial, goal-directed (i.e., teleological) action. Four possible models have been suggested: finalist, complexity based, biology based, and animal based. In Study 1, participants (N = 104) were assigned to one of two conditions that differed in whether a beneficial or neutral object was pictured; they were asked to predict whether animals, plants, machines, and simple artifacts would modify their movement in the direction of that object. Preschoolers' predictions were consistent with an animal-based model, fifth graders' predictions were consistent with biology-based and complexity-based models, and adults' predictions were consistent with a biology-based model. Analysis of both individual response patterns and explanations supported these findings, but also showed that a significant number of preschoolers and fifth graders were finalist, and that very few individual fifth graders followed a complexity-based teleology. In Study 2, participants (N = 84) reported whether the animals, plants, machines, and simple artifacts in Study 1 had psychological capacities. All age groups attributed psychological capacities to animals at levels higher than other domains and at above-chance levels. The evidence from these two studies suggests that preschoolers, unlike fifth graders and adults, predict teleological action for plants and animals on the basis of these entities' inferred psychological capacities. 相似文献

The National Science Education Standards emphasise teaching unifying concepts and processes such as basic functions of living organisms, the living environment, and scale. Scale influences science processes and phenomena across the domains. One of the big ideas of scale is that of surface area to volume. This study explored whether or not there is a correlation between proportional reasoning ability and a student's ability to understand surface area to volume relationships. Students' knowledge of surface area to volume relationships was assessed pre and post to a one‐week instructional intervention involving investigations about surface area to volume as a limiting factor in biological and physical systems. Results showed that proportional reasoning scores of middle school students were correlated to pre‐test and post‐test assessment scores, and a paired‐sample t‐test found significant differences from pre‐test to post‐test for the surface area to volume assessment. Relationships between proportional reasoning, visualisation abilities and success in solving surface to volume problems are discussed. The implications of the results of this study for learning concepts such as magnitudes of things, limits to size, and properties of systems that change depending on volume and surface are explored. 相似文献

This study investigated the effects of peer collaboration anddiscourse patterns on conceptual change in the context of high-schoolstudents learning from incompatible scientific information. The domainof investigation was biological evolution. Participants included 108students from Grades 9 and 12 randomly assigned to four conditions: (1)peer-conflict; (2) individual-conflict; (3) peer-assimilationand (4) individual-assimilation. Students were asked to think aloud ordiscuss with their peers eight statements consisting of scientificinformation ordered in ways that either maximized or minimized conflict.Several measures of prior knowledge and conceptual change were obtained.Peer collaboration resulted in some mixed findings suggesting that peereffects may vary depending on collaborative interactions. In-depthanalyses of collaborative interactions indicated two discourse patterns:surface moves included rating, ignoring, rejecting, and patching toeliminate differences; problem-centred moves involved problemrecognition, formulation of questions, and construction of explanations.Comparisons between successful and unsuccessful learners showedsignificant differences in their proportional use of surface andproblem-centred moves. External conflict did not lead to deeperdiscourse and more conceptual change; students may need toexperience meaningful conflict. These findings suggest why peercollaboration only works sometimes and indicate the importance ofhelping students to engage in productive discourse. 相似文献

A conceptual analysis of Heider's level 3 foreseeability rule for the attribution of responsibility suggests that it is more difficult than levels 2 (commission) and 4 (intentionality) because it requires forms of reasoning ascribed to Piaget's formal operational thought. Thus, the rule should be acquired in early adolescence, or later. Previous studies showing foreseeability attributions in younger children have been confounded by the fact that their stimulus materials required an inference of intentionality. The present study, of 5-15-year-olds, avoided this confound by using an "omniscient narrator" technique to control the children's inferences of intent. The results suggest that children first employ Heider's commission rule, then his intentionality rule, and finally adopt the foreseeability rule at about 11 years. The study did not assess whether or not foreseeability attribution is a "stage" in the sense of Piaget's formal operational thought. 相似文献

If our goal as researchers is to understand the range and complexity of human conceptual development, increased attention to comparative research is essential. I draw on research in the domain of folkbiology-commonsense understandings of plants and animals--to argue that several lines of comparative research are needed to understand the acquisition of folkbiology in particular and conceptual development in general. First, comparisons are needed between children and adults within a given society. It is impossible to understand the process of conceptual development without a detailed look at adult endstates in a domain. Second, comparisons are needed between adult endstates in different contexts. For a complete understanding of conceptual development we must understand the range of variability of adult conceptual systems. Finally, comparisons are needed among children developing in different contexts. Such research complements comparative work on adults and would serve to distinguish between universal and particular patterns of development and thus to inform and constrain accounts of conceptual development. 相似文献

The study of human learning and development from situative or sociocultural perspectives has had significant impacts on a wide range of scholarship largely driven by the theoretical and methodological focus on understanding the role of activity systems in cognition and development. This article first explores how situative perspectives have advanced fundamental knowledge about how culture and race impact learning and development and works to demonstrate how these understandings have enabled new insights into folk-biological cognition. Traditional cognitive, cross-cultural, and situative perspectives with respect to folkbiology are compared and contrasted to demonstrate how situative perspectives enabled more complete understandings of the complexities of biological cognition. These complexities are conceptualized as the conceptual and epistemological ecologies of activity systems. Implications for education are considered. 相似文献

This study investigated preschoolers' living kinds conceptualization by employing an extensive stimulus set and alternate indices of understanding. Thirty-four 3- to 5-year-olds and 36 adult undergraduates completed 3 testing phases involving 4 object classes: plants, animals, mobile, and immobile artifacts. The phases involved inquiries participants generated, what biological properties they attributed and their assignment of "alive" to the 4 classes. The study also focused on preschoolers' conceptual coherence by examining their responding across indices. Results revealed both competence and confusion in preschoolers' living kinds conceptualization relative to adults'. In addition, demonstrations of coherence across testing situations suggest that the beginnings of an abstract, biologically organized framework for understanding of living and nonliving kinds are in place in the preschool period. 相似文献

Minds, modules, and meta-analysis 总被引：5，自引：0，他引：5
Wellman and colleagues' meta-analysis of performance on the false-belief task is methodologically useful, but it does not lead to any theoretical progress concerning the nature of the mechanisms that underlie the existence and development of "theory of mind." In particular, the results of this meta-analysis are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. The arguments presented by Wellman and colleagues against such views stem not from their meta-analytic data, but from mistaken assumptions regarding the requirements of such theories (e.g., that there exist manipulations that improve performance only, or to a greater degree, in young children). Contrary to what Wellman and colleagues claim, their meta-analysis, while consistent with conceptual change, does not lend any new support for such theories. 相似文献

Conceptual change: a discussion of theoretical, methodological and practical challenges for science education 总被引：2，自引：0，他引：2
Conceptual change views of teaching and learning processes in science, and also in various other content domains, have played
a significant role in research on teaching and learning as well as in instructional design since the late 1970s. An important
issue is whether conceptual change can provide a powerful framework for improving instructional practice in such a way that
students’ levels of scientific literacy are significantly increased. In this article, the first section provides an overview
on the development of conceptual change perspectives. In sections two to six, we examine the different ways that researchers
have facilitated the collection of data and empirically evaluated learning as conceptual change based on these different theoretical
perspectives. In section seven, we identify key issues of conceptual change with a deliberate emphasis on their contribution
to improve instructional practice and conclude the article by posing challenges at theoretical, methodological and practical
levels. We contend that conceptual change perspectives still have the potential to significantly improve instructional practice.
However, it becomes also evident that actual practice is far from what conceptual change perspectives propose and that change
of this practice will be a rather difficult and long-lasting process.

文章从概念隐喻理论出发,探讨了委婉语的生成机制,认为隐喻作为人类思维的一种基本认知方式,主要包括方位隐喻、本体隐喻和结构隐喻,这些隐喻运作的基础都是事物之间的相似性,是以一种事物或经验来理解和体验另一种事物或经验,本质是两个概念域之间基于相似性的跨域映射,而正是这种跨域映射所造成的认知的间接性使得委婉语的生成成为可能。 相似文献

Two studies ( N = 456) compared the development of concepts of animal species and human gender, using a switched-at-birth reasoning task. Younger children (5- and 6-year-olds) treated animal species and human gender as equivalent; they made similar levels of category-based inferences and endorsed similar explanations for development in these 2 domains. In contrast, 10-year-olds and adults treated gender and species concepts as distinct from one another. They viewed gender-linked behavioral properties as open to environmental influence and endorsed environment-based mechanisms to explain gender development. At all ages, children demonstrated differentiated reasoning about physical and behavioral properties, although this differentiation became more stable with age. The role of psychological essentialism in guiding conceptual development is discussed. 相似文献
