This article presents the results of an experiment which investigated elementary school children's explanations of the day/night cycle. First, third, and fifth grade children were asked to explain certain phenomena, such as the disappearance of the sun during the night, the disappearance of stars during the day, the apparent movement of the moon, and the alteration of day and night. The results showed that the majority of the children in our sample used in a consistent fashion a small number of (...) relatively well‐defined mental models of the earth, the sun, and the moon to explain the day/night cycle. These mental models of the day/night cycle were empirically accurate, logically consistent and revealed some sensitivity on the part of the children to issues of simplicity of explanation. The younger children formed Initial mental models which provided explanations of the day/night cycle based on everyday experience (e.g., the sun goes down behind mountains, clouds cover up the sun). The older children constructed synthetic mental models (e.g., the sun and the moon revolve around the stationary earth every 24 hours; the earth rotates in an up/down direction and the sun and moon are fixed on opposite sides) which represented attempts to synthesize the culturally accepted view with aspects of their Initial models. A few of the older children appeared to have constructed a mental model of the day/night cycle similar to the scientific one. A theoretical framework is outlined which explains the formation of initial, synthetic, and scientific models of the day/night cycle in terms of the reinterpretation of a hierarchy of constraints, some of which are present early in the child's life, and others which emerge later out of the structure of the acquired knowledge.

In this paper we provide a psychological account of the nature and development of explanation. We propose that an explanation is an account that provides a conceptual framework for a phenomenon that leads to a feeling of understanding in the reader/hearer. The explanatory conceptual framework goes beyond the original phenomenon, integrates diverse aspects of the world, and shows how the original phenomenon follows from the framework. We propose that explanations in everyday life are judged on the criteria of empirical accuracy, (...) scope, consistency, simplicity, and plausibility. We conclude that explanations in science are evaluated by the same criteria, plus those of precision, formalisms, and fruitfulness. We discuss several types of explanation that are used in everyday life – causal/mechanical, functional, and intentional. We present evidence to show that young children produce explanations that have the same essential form as those used by adults. We also provide evidence that children use the same evaluation criteria as adults, but may not apply those additional criteria for the evaluation of explanations that are used by scientists.

This study investigated their views concerning evidence and expert opinion of 10th‐grade students, accessed by an open‐ended questionnaire in the context of a socio‐scientific issue: the cause of flood disasters, and personal epistemology identified by the Learning Environment Preference Questionnaire . Students' responses to the open‐ended questions showed that when thinking about the flood issue, most students rely heavily on direct and numerical data to draw their conclusions, while experts represented a source of conclusive information. The LEP scores indicated that, (...) in terms of epistemological development, students were mostly at the stage of the ‘multiplicists’ in Perry's model. The statistical analysis suggested that view towards evidence and expert were associated with personal epistemology. (shrink)

Magical thinking and behaviour have traditionally been viewed as immature, misleading alternatives to scientific thought that in children inevitably diminish with age. In adults, these inclinations have been labeled by psychologists largely as superstitions that feed on frustration, uncertainty, and the unpredictable nature of certain human activities. In Magic and the Mind, Eugene Subbotsky provides an overview of the mechanisms and development of magical thinking and beliefs throughout the life span while arguing that the role of this type of thought (...) in human development should be reconsidered. Rather than an impediment to scientific reasoning or a byproduct of cognitive development, in children magical thinking is an important and necessary complement to these processes, enhancing creativity at problem-solving and reinforcing coping strategies, among other benefits. In adults, magical thinking and beliefs perform important functions both for individuals (coping with unsolvable problems and stressful situations) and for society (enabling mass influence and promoting social harmony). Operating in realms not bound by physical causality, such as emotion, relationships, and suggestion, magical thinking is an ongoing, developing psychological mechanism that, Subbotsky argues, is integral in the contexts of politics, commercial advertising, and psychotherapy, and undergirds our construction and understanding of meaning in both mental and physical worlds. Magic and the Mind represents a unique contribution to our understanding of the importance of magical thinking, offering experimental evidence and conclusions never before collected in one source. It will be of interest to students and scholars of developmental psychology, as well as sociologists, anthropologists, and educators. (shrink)
