This study examined standard 6 and 8 (Standards 6 and 8 are the sixth and eighth years, respectively, of primary level schooling
in Kenya.) students’ perceptions of how they use mathematics and science outside the classroom in an attempt to learn more
about students’ everyday mathematics and science practice. The knowledge of students’ everyday mathematics and science practice
may assist teachers in helping students be more powerful mathematically and scientifically both in doing mathematics and science
in school and out of school. Thirty-six students at an urban school and a rural school in Kenya were interviewed before and
after keeping a log for a week where they recorded their everyday mathematics and science usage. Through the interviews and
log sheets, we found that the mathematics that these students perceived they used outside the classroom could be classified
as 1 of the 6 activities that Bishop (Educ Stud Math 19:179–191, 1988) has called the 6 fundamental mathematical activities and was also connected to their perception of whether they learned
mathematics outside school. Five categories of students’ perceptions of their out-of-school science usage emerged from the
data, and we found that 4 of our codes coincided with 2 activities identified by Lederman & Lederman (Sci Child 43(2):53,
2005) as part of the nature of science and 2 of Bishop’s categories. We found that the science these students perceived that they
used was connected to their views of what science is. 相似文献

Current theory about writing states that the quality of (meta)cognitive processing (i.e. planning, text production, revising,
et cetera) is, at least partly, determined by the temporal distribution of (meta)cognitive activities across task execution.
Put simply, the quality of task execution is determined more by when activities are applied than by how often they are applied. Planning and revising are two extreme writing styles, in which (meta)cognitive activities are temporally differently distributed across the writing
process. Planners are writers who generate plans before text production. Revisers use text production as a means to arrive
at a content plan. The present study investigates the question whether the online (meta)cognitive processing of secondary
school students during writing tasks, as measured by think aloud techniques and keystroke logging, can be predicted by their
responses to an offline questionnaire which measures to what degree students considered themselves to be planners and revisers.
It was expected that different reported writing styles would entail different temporal distributions of six (meta)cognitive
activities: reading the assignment, planning, text production, reading own text, evaluating own text and revising. This hypothesis
was partly confirmed. The results show that the online temporal distributions of reading the assignment and planning are different
for different degrees of reported writing styles. On the basis of these results, the validity of both the questionnaire and
the concept of planner and reviser styles are discussed. 相似文献

Efforts to identify and support credible causal claims have received intense interest in the research community, particularly
over the past few decades. In this paper, we focus on the use of statistical procedures designed to support causal claims
for a treatment or intervention when the response variable of interest is dichotomous. We identify seven key features of logistic
regression studies that should play a critical role in estimating a causal effect and discuss their implications for causal
inference. These include elaboration of research design, clarification of link function, model specification, challenges and
limitations of sample size, interpretation of treatment effect through odds ratios, statistical tests and examination of model
fit, and the potential for multilevel logistic models in pursuit of causal claims. Our recommendations are intended to guide
researchers in the critical evaluation of logistic regression models for analyses culminating in causal claims and to promote
stronger design and modeling strategies for reliable causal inference. 相似文献

Interpersonal transcendence is a phenomenon marked by total immersion in an interaction, a deep sense of understanding, feelings of mutuality, new insight, and playfulness. Such experiences can be exhilarating, memorable, and rare. This study examines relationships between various listening dispositions and people’s propensity to experience interpersonal transcendence. Participants (N = 300) completed the Interpersonal Transcendence Scale (ITS) along with the Listening Styles Inventory (LSI), the Active Empathic Listening scale (AEL), and the Listening Styles Profile–Revised (LSP-R). Results indicated substantial relationships between ITS responses and the LSI and AEL. The LSP-R dimensions of Relational Listening and Analytical Listening were also related to ITS responses. Other results indicate that propensity to experience interpersonal transcendence is associated with minority group status and age. 相似文献

城市建设用地的潜在生态适宜性评价——以上海市宝山区为例 总被引:1,自引:0,他引:1
在城市快速扩张的区域,传统基于土地利用现状的生态适宜性评价方法在支持未来城市建设用地的开发决策方面具有一定的局限性。本文首次提出了城市建设用地潜在生态适宜性评价的概念和方法,把模拟预测得到的未来城市土地利用分布作为重要因子加入生态适宜性评价框架,生成更适合于未来城市建设用地规划决策的潜在生态适宜性评价结果。以上海市宝山区为例,空间化展现城市用地扩张背景下的2050年城市建设用地潜在生态适宜性分布情况,并与传统生态适宜性评价结果进行空间量化对比分析。分析结果表明,潜在生态适宜性评价有效降低了不适宜及较不适宜开发用地与未来城市建成区重叠度较高的矛盾(分别由9.74%和22.7%降低为0.0%和14.5%),能更好地匹配城市开发边界规划和生态空间规划,突显未来发展过程中的生态保护重点区域。本文实证了新方法的科学性和有效性,该方法能更好地为城市扩张背景下的生态城市规划提供决策支持。 相似文献

The standard impact factor allows one to compare scientific journals only within particular scientific subjects. To overcome
this limitation, another indicator of citation, viz., the thematically weighted impact factor (TWIF), is proposed. This indicator
allows one to compare journals of various subjects and takes the fact that a journal belongs to several subjects into account.
Information on the thematic headings of a journal and the value of a standard impact factor is necessary for calculation of
the indicator. The TWIF, which is calculated according to the citation index of Journal Citation Reports, is investigated in this article. 相似文献

ABSTRACTDespite the importance of interactions with natural environments for personal and social well-being, there is only limited evidence of the relationship between the environment and health as an idea or area of study in school education in Australia. Logically, the place for such a study, at least in Australia, would be within the Health & Physical Education (HPE) key learning area. However, in HPE, alternative ways of considering health beyond the dominant ‘healthism’ discourses which privilege physical activity, fitness, food and nutrition struggle for any kind of existence. Gruenewald (2004. A Foucauldian analysis of environmental education: Toward the socioecological challenge of the earth charter. Curriculum Inquiry, 34(1), 71–107) suggests looking to the margins of a field to see what knowledge is silenced or subjugated in order to open up new conditions of possibility. This challenged us to look beyond taken for granted ways of thinking about health to identify other resources, perhaps unrecognised as yet, that teachers might draw on to constitute their knowledge of health. To do this, we look to interview data collected when teachers were asked to talk about their personal experiences of the relationship between the environment and health. The analysis of the interviews demonstrated how the teachers conceptualised the relationship between the environment and health by drawing on embodied experiences and affective encounters with more-than-human nature. By theorising these encounters through a post-human, new-materialist lens, we demonstrate how their corporeal knowledge, developed through embodied experiences, has the potential to assist teachers in formulating less institutionalised health understandings. We argue that these encounters with more-than-human nature can serve as alternatives to those dominant healthism discourses that invoke problematic risk, fear and crisis responses. 相似文献
