In order to acquire a theory of biology, children must acquire knowledge about living kinds. Although many studies have shown that preschool children do not accurately classify living kinds and do not use appropriate properties when asked to decide whether something is a living kind, recent work has shown that 3- and 4-year-olds do know something about biological growth. The ability of kinds to heal through regrowth was used in this paper as a measure of children's implicit understanding that plants and animals can be grouped together. In 3 experiments, children were told that animals, plants, and artifacts had been damaged and were asked whether the objects could heal through regorwth and whether a person could mend them. In all studies, children were sensitive to ontological kind, 4-year-olds realized that both plants and animals can regrow but that artifacts must be fixed by human intervention. 3-year-olds were less knowledgeable but did realize that artifacts cannot regrow. Overall, children showed some biological knowledge, implicity grouping plants and animals together and differentiating them from artifacts. 相似文献
We investigated associations between children's representations of mothers in their play narratives and measures of children's and mother socioemotional adaptation, and explored the development of these representations between the ages of 4 and 5 years. Fifty-one children were interviewed using the MacArthur Story-Stem Battery to obtain their narrative representations of mothers. Positive, Negative, and Disciplinary representation composites were generated. Children who had more Positive and Disciplinary representations and fewer Negative representations had fewer behavior problems and their mothers reported less psychological distress. In addition, 5-year-olds had more Positive and Disciplinary representations and fewer Negative representations did 4-year-olds, and there was moderate stability in individual differences in children's representations of mothers across the 2 ages. The results add an important dimension to research on parent-child relationships—that of children's perspectives on these relationships. 相似文献
The Federal Communications Commission is considering whether to strengthen the implementation of the Children's Television Act of 1990, which requires broadcasters to air educational and informational programs for children. Some broadcasters have opposed such measures, arguing that not enough children will watch educational programs. This argument assumes that children distinguish between educational and non‐educational programs, find educational programs less appealing, and consequently are unlikely to watch them. The present study tests these assumptions directly, through a comparison of two animated programs set in prehistoric times, Cro (an educational program about technology) and The Flintstones (a non‐educational program). Results indicated that Cro’s technology content was salient to children but, contrary to the above assumptions, children did not distinguish between the programs on the basis of their educational content, and both programs were highly appealing. 相似文献
This paper reports two studies investigating the nature of comprehension deficits in a group of 7–8 year old children whose decoding skills are normal, but whose reading comprehension skills are poor. The performance of these poor comprehenders was compared to two control groups, Chronological-Age controls and Comprehension-Age controls. The first study examined whether these comprehension difficulties are specific to reading. On two measures of listening comprehension the poor comprehenders were found to perform at a significantly lower level than Chronological-Age controls. However, they did not differ from a group of younger children matched for reading comprehension skills. This indicates that the observed comprehension difficulties are not restricted to reading, but rather represent a general comprehension limitation. The second study investigated whether these comprehension difficulties can be explained in terms of a memory deficit. The short-term and working memory skills of these three groups were examined. The poor comprehenders did not differ from their Chronological-Age controls on either of these tasks. In conclusion, it is argued that working memory processes are not a major causal factor in the creation of the comprehension difficulties identified in the present group of poor comprehenders. 相似文献
Throughout their history, museums have performed diverse public services: from preservation, collection, and exhibition, to interpretation, education, and civic engagement. As Stephen E. Weil ( 2002 ) explains, since the mid‐twentieth century, museums have experienced two major revolutions. First, a revolution in focus from collection‐oriented to visitor‐oriented practices, and second, a revolution in public expectations as museums secured a position within the nonprofit sector (81–82). With competition for public, private, and philanthropic support resting upon measurable results, the evaluation of museums depends upon its ability to “accomplish its purpose” (5). However, the question remains: what is the museum's purpose? Which is the more important: collection and artifact preservation, or public engagement and education? An overview of museum practices reveals a multiplicity of professional tasks distributed among three imperatives: preservation, scholarship, and programming (Weil 2002 , 11). The competition for resources devoted to each of these imperatives can spark controversy—particularly if museum professionals answer the question of the purpose of museums differently. Organizational communication scholar, Janie M. Harden Fritz, developed a theoretical framework that seeks to respond to such controversies in Professional Civility: Communicating Virtue at Work. This essay considers Fritz's “professional civility” in the context of the American museum sector, lending insight to the question of museum purpose and function. 相似文献
As classrooms continue to diversify, there is an increasing need to understand children’s inclusive behaviours and moral reasoning. Research shows that epistemic beliefs (beliefs about knowing and knowledge) can influence reasoning for adults, but we know little about this relationship in younger children or how classroom contexts relate to epistemic beliefs for moral reasoning. Thirty-one elementary school children (mean age 6.5 years) participated in epistemic beliefs and moral reasoning tasks in the first year of a three-year longitudinal study. Findings showed that while children described objectivist epistemic beliefs (right/wrong answers) about social inclusion, their justifications revealed an unexpected, more complex set of epistemic beliefs. Implications for moral pedagogies are discussed. 相似文献
Background: Uncertainty is a crucial element of scientific knowledge growth. Students should have some understanding of how science knowledge is developed and why scientific conclusions are considered more or less certain than others. A component of the nature of science, it is considered an important aspect of science education and allows students to recognize the limitations of scientific research.
Purpose: This study examined Grades 5 and 9 students’ views of uncertainty in their personal scientific research and the formal scientific research of professionals.
Sample: This study included 33 students in Grade 5 (n = 17) and Grade 9 (n = 16). The students were recruited from a charter school that emphasised inquiry instruction.
Design and methods: Data were collected through interviews. Students were asked their views of their inquiry-based projects and their views of professional science.
Results: Interview data and statistical analyses indicated that students recognized uncertainty in personal science, which varied across elements of the scientific process. Additionally, their views of uncertainty in formal science tended to change across grades and knowledge of uncertainty in personal and formal science were positively correlated.
Conclusion: These findings offer insights into the processes by which students come to understand uncertainty in science and point to ways of fostering such knowledge through teaching practices. 相似文献
This paper examines Vygotsky’s conception of play as a leading activity in the contexts of children’s contemporary play worlds. Commencing with an examination of the relationship between leading activities and the development of psychological functions, the paper moves into a consideration of the relationship between imagination and reality as a basis for play as a leading activity. The relationship is considered in the context of current discussion regarding the sociology of childhood and the sociology of consumerism to explore the ways in which children’s experiences in digital–consumerist contexts possibly shape learning and development. Drawing on the example of the highly popular character Thomas the Tank Engine?, the paper examines the implications associated with understanding play as a leading activity within contemporary contexts, and how these might relate to existing perspectives on play, pedagogy and curriculum in early childhood education settings. 相似文献
Pseudoscience beliefs (e.g., astrology, ghosts or UFOs) are rife in American society. Most research examines creation/evolution
among liberal arts majors, general public adults, or, infrequently, middle or high school science teachers. Thus, research
truncates the range of ersatz science thinking and the samples it studies. We examined diverse beliefs, e.g., extraterrestrials, magic, Biblical creation, and evolution, among 540 female and 123 male future teachers, including 325 elementary education majors. We study
how these cognitions related to education major and, because popular media often present pseudoscience “information”, student
media use. Future elementary educators most often rejected evolution and endorsed “creationism” or Intelligent Design. Education
majors held similar beliefs about astrology, UFO landings, or magic. Compared with other education students, elementary education
majors watched less news or science television and read fewer popular science magazines. However, religious and media variables
explained more variation in creation/evolution beliefs than education major. We discuss implications of our findings for elementary
school science education and how teacher educators may be able to affect pseudoscience beliefs among their elementary education
students. 相似文献
