This paper is concerned with organizational principles of a pool of familiar problems of expert problem posers and the ways by which they are utilized for creating new problems. The presented case of Leo is part of a multiple-case study with expert problem posers for mathematics competitions. We present and inductively analyze the data collected in a reflective interview and in a clinical task-based interview with Leo. In the first interview, Leo was asked to share with us the stories behind some problems posed by him in the past. In the second interview, he was asked to pose a new competition problem in a thinking-aloud mode. We found that Leo’s pool of familiar problems is organized in classes according to certain nesting ideas. Furthermore, these nesting ideas serve him in posing problems that, ideally, are perceived by Leo as novel and surprising not only to potential solvers, but also to himself. Because of the lack of empirical research on experts in mathematical problem posing, the findings are discussed in light of research on experts in problem solving and on novices in mathematical problem posing. 相似文献

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups. 相似文献

Research on memory for time has been limited by the difficulty of disentangling several of the fundamentally different processes that contribute to a chronological sense of the past. This study used a developmental approach to isolate one of these processes, impressions of distances in the past. Large samples of children between 3 and 12 years were asked to judge which was longer ago, their birthday or Christmas (and, in one study, Halloween and Thanksgiving). Even children under 6 years of age were able to discriminate the recency of their birthday and Christmas with great accuracy when the events were widely separated and one was within the past several months. The ability to discriminate recency on these scales appears to be a basic property of human memory that changes little with development. Other information about the locations of the events and their relative times of occurrence could only be interpreted correctly by children older than 9 years. 相似文献

Previous research on adults' and children's memory for the time of past events has generally overlooked the fundamental distinction between knowledge of temporal distance in the past and knowledge of temporal locations. This study applied the distinction to the development of time memory. Children of 4, 6, and 8 years of age experienced 2 target events, one 7 weeks and the other 1 week before testing. They were asked to judge the relative recency of the 2 events and to localize the older event by time of day, day of the week, month, and season. Even the 4-year-olds were successful in judging the relative recency of the 2 events and localizing the older event by time of day. However, on the 3 longer time scales, only the 6- and 8-year-olds could localize the older event, reason about possible times that it could have occurred, or tell the present time. The great accuracy of the time-of-day judgments at all 3 ages is almost certainly not due to distance-type information. The results show the separate development of distance and location judgments. 相似文献

Adults have a rich understanding of a number of time systems, but little is known about how this knowledge develops. 3 experiments were conducted to test a model in which the first representations of the days of the week and months of the year have verbal-list properties, and these are later supplemented by image representations. In Experiments 1 and 2, fourth or fifth graders could judge forward relative order for these contents, but not until adolescence could backward order judgments be made accurately. In Experiment 3, fourth graders used a serial process to solve a categorical distance judgment task, whereas older groups shifted to a process with more rapid access to information about the position of remote items. The results are interpreted as supporting the 2-stage model and appear inconsistent with a number of alternative models. 相似文献

ABSTRACTThe research focuses on the complexities associated with contemporary rural primary school leadership. The paper draws on in-depth ethnographic research undertaken in two contrasting English rural primary schools and their surrounding community over a period of three years and in particular the experiences and perspectives of the two head teachers from these schools. The paper is conceptually informed by the work of Bourdieu [1984. Distinction: A Social Critique of the Judgement of Taste. London: Routledge and Kegan Paul] and his work around field, habitus and capital as a means of understanding practice. The paper contends that as the neo-liberal economic field increasingly contaminates the field of schooling so a contextual understanding of the complex and shifting social space which a head teacher occupies, including their habitus and the capital they deploy, is of central importance to understanding practice. 相似文献

This study examines the experiences of transgender college students in coping with stress in comparison to their cisgender peers. Undergraduate and graduate students from 73 colleges, totaling 26,292 participants, of which 47 identified as transgender completed an online survey. Transgender students reported greater exposure to trauma and higher rates of suicidal experiences, as well as different precipitants to reported stressful periods and sources of support than their cisgender peers. Implications for individual and group counseling as well as outreach and prevention to better support transgender students are explored. 相似文献

Relying on Bronfenbrenner’s ecological model, this paper attempts to identify school-level factors that contribute to effective implementation of inclusive education. We also explored how government policy, with emphasis on individual education plans, school teams, Roma assistants and inter-sectorial committees, is implemented at the school level. Qualitative data were collected from various informants (students, parents, teachers, school associates, Roma assistants and local community representatives) in five schools selected on the basis of regional distribution and success in supporting diverse student needs. Two core categories of school-level facilitators were generated: inclusive practices and inclusive culture. Within the first category, which refers to concrete actions and relationships in the school and local community, five themes emerged: individualisation and use of individual education plans; cooperation between teachers and school inclusive education expert team; cooperation with internal and external specialists; cooperation with parents, and cooperation with the local community. The second category, which reflects beliefs, values and implicit school norms, was further divided into five subcategories: willingness for life-long learning; proactive stance; sense of teamwork; sophisticated personal philosophies of development and learning; and acceptance of difference. We concluded that successful schools have developed into professional learning communities. Finally, recommendations for improving relevant practices were provided. 相似文献
