The study reported here examined grade 2–4 children’s sensitivity to the consistency in the spelling of roots in related words. We build on earlier research by attempting to quantify the extent that children’s spellings of both inflected and derived forms accord with this principle. We contrasted children’s accuracy and consistency in spelling the root form (e.g., rock) with that of its spelling in related inflected and derived forms (e.g., rocks and rocky), as well as unrelated control forms (e.g., rocket). Across grades 2–4, children’s spellings accorded with the root consistency principle to the same extent for inflected and derived forms. Nevertheless, it was not until grade 4 that spellings maximally reflected the principle. These results are discussed in terms of how children’s spelling might come to reflect the root consistency principle that guides spelling in English.  相似文献

Louise Erdrich is one of the most influential writers of the Native American Renaissance. Her contributions to the representation of Native American history have been great, and her masterpieces of children’s literature have won her a prominent reputation. This article explores the (re)location of the concept of home in Erdrich’s The Game of Silence and analyzes the novel’s historical context with reference to various discourses on space/place, including those by Native Americans. Erdrich’s narration reconstructs a space for Native American culture, religion and tradition, and for the continued survival of Native American people. She represents the silent history of her ancestors’ displacement to the West, as white settlers encroached upon their beloved homeland. As Erdrich’s work so poignantly illustrates, for Native American people, home is nowhere and anywhere.  相似文献

Objective To investigate the actions of Swedish preschool staff when suspecting the maltreatment of children in their domestic environment, and the staff’s further experiences and relations to the family members. Methods A questionnaire in 2005 to the staff of 189 child groups in community preschools, including 3,100 children. Results A report to Child Protective Agency (CPA) was submitted in 30% of the cases where maltreatment was suspected. The staff’s decisions as well as their working situation, and how they estimated the parents’ benefits from CPA support were deeply affected by their different relations to the families. The staff had their best contact with the children and their most insecure and vulnerable contact with the fathers. Conclusions In situations with suspected child maltreatment the staff face conflicts of loyalty, mostly based on insecure relations, which could become an impediment to supporting and educating the children.  相似文献

Research repeatedly documents that teachers are underprepared to teach mathematics effectively in diverse classrooms. A critical aspect of learning to be an effective mathematics teacher for diverse learners is developing knowledge, dispositions, and practices that support building on children’s mathematical thinking, as well as their cultural, linguistic, and community-based knowledge. This article presents a conjectured learning trajectory for prospective teachers’ (PSTs’) development related to integrating children’s multiple mathematical knowledge bases (i.e., the understandings and experiences that have the potential to shape and support children’s mathematics learning—including children’s mathematical thinking, and children’s cultural, home, and community-based knowledge), in mathematics instruction. Data were collected from 200 PSTs enrolled in mathematics methods courses at six United States universities. Data sources included beginning and end-of-semester surveys, interviews, and PSTs’ written work. Our conjectured learning trajectory can serve as a tool for mathematics teacher educators and researchers as they focus on PSTs’ development of equitable mathematics instruction.  相似文献

China’s Western Development is a policy adopted to boost its less developed Western regions, that is, a systematic project and a longterm and arduous task. The development of compulsory education in China’s minority areas is the key to it. This paper attempts to use the beneficial experience of developing compulsory education support system of other countries for reference so as to explore financial support system suitable for the situation of China’s compulsory education in minority areas. __________ Translated from Minzu Jiaoyu Yanjiu 民族教育研究 (Journal of Research on Education for Ethnic Minorities), 2007, 18 (2): 16–23  相似文献

In this work an attempt is made to explore the possible value of using Thought Experiments (TEs) in teaching physics to upper secondary education students. Specifically, a qualitative research project is designed to investigate the extent to which the Thought Experiment (TE) called ‘Heisenberg’s Microscope’, as it has been transformed by Gamow for the public in his book Mr. Tompkins in Paperback, can function as a tool in the teaching of the ‘uncertainty principle’. The sample in the research consisted of 40 Greek students, in 11 groups of 3–4 students each. The findings of this study reveal that the use of this TE has positive results in teaching the uncertainty principle. Students, based on the TE, were able (i) to derive a formula of the uncertainty principle, (ii) to explain that the uncertainty principle is a general principle in nature and it is not a result of incompleteness of the experimental devices and (iii) to argue that it is impossible to determine the trajectory of a particle as a mathematical line.  相似文献

The purpose of this study is to examine fathers’ participation in and views about play. This study was conducted in the southwestern part of Turkey and its sample consisted of 97 fathers who had a child attending randomly chosen public early childhood institutions. The Parents’ Participation and Views on Play instrument was developed and used to collect data. Independent sample t tests and a series of repeated measures analysis of variance procedures were conducted to assess the influence of independent variables on the fathers’ participation in and views on play. The results of the study indicated that fathers frequently participated in their children’s play, and they hold positive views about play. Fathers’ socio-demographic characteristics such as income, working status, family type and children’s gender influenced their participation and views about play. Results are discussed in relation to the literature on parent–child play and suggestions for further research are presented.  相似文献

This study examines the relationship between working memory and reading achievement in 57 Swedish primary-school children with special needs. First, it was examined whether children’s working memory could be enhanced by a cognitive training program, and how the training outcomes would relate to their reading development. Next, it was explored how differential aspects of working memory are related to children’s reading outcomes. The working memory training yielded effects, and these effects appeared beneficial to children’s reading comprehension development. Working memory measures were found to be related with children’s word reading and reading comprehension. The results show that working memory can be seen as a crucial factor in the reading development of literacy among children with special needs, and that interventions to improve working memory may help children becoming more proficient in reading comprehension.  相似文献

In this Forum paper we synthesize some of the main ideas from three papers: Auli Orlander and Per-Olof Wickman’s (Cult Stud Sci 6, 2011), Bodily experiences in secondary school biology, Roger Sages’ (Cult Stud Sci Educ 6, 2011), About Descartes: Uses and misuses, and Steve Alsop’s (Cult Stud Sci Educ 6, 2011), The body bites back! These papers challenged us to identify how emotions functioned as elements of bodily experiences in classroom transactions and why science teachers often are not responsive to students’ emoting. We also explored how teachers making use of curriculum and companion meanings could support the construction of learning environments that more productively support students’ science learning.  相似文献

This study investigates the mechanisms of scaffolding in a synchronous network-based environment – the ‘collaborative virtual workplace’. A theoretical ‘multi-actor’ scaffolding model was formulated. The study itself focused on the role and inter-relations of verbal scaffolding by tutor and peers during a collaborative process of making decisions about environmental issues. The analysis drew on data from the decision-making discussions of 31 groups – material that was saved automatically by the learning environment software. The age of the 62 students ranged from 14 to 17. Discourse act categories were devised to describe the tutor’s and the students’ task-related, supportive and social communicative acts. The scaffolding situation was characterized through a causal discourse act interaction approach. Tutor and students appeared to be elaborating and replacing each other’s process scaffolding acts in the collaborative decision-making situation. The influence of certain tutor’s and students’ inter-related scaffolding patterns on students’ decision-making provided empirical support for the ‘multi-actor’ scaffolding model. in final form: 12 May 2005  相似文献

The gravitational field of a massive, spherical, body like the Sun is described in general relativity by a solution to Einstein’s equations called the Schwarzschild soution. Here is an elementary persepective on this solution, which — though far from a rigourous derivation — raises intriguing questions. T Padmanabhan works at IUCAA, Pune and is interested in all areas of theoretical physics, especially those which have something to do with gravity. This is based on an article originally published by the author in Physics Education, Vol. 23, No.1, p.47, 2006.  相似文献

Assumptions about the construction and the transmission of knowledge and about the nature of mathematics always underlie any teaching practice, even if often unconsciously. I examine the conjecture that theoretical tools suitably chosen can help the teacher to make such assumptions explicit and to support the teacher’s reflection on his/her previous as well as future educational practice. In particular, I show how an epistemological vision of mathematics in resonance with a model of cognitive dynamics can work as a powerful tool to support a teacher’s stable and autonomous attitude of noticing. To support this argumentation, I present some experimental data concerning a case study of one teacher. Through a methodological frame suitably arranged I try to describe how the teacher’s ability to rely on this particular theoretical frame affects: the choice of the global goals in mathematics education; the design of educational interventions; the interpretation of learners’ cognitive behaviours; and the assessment.  相似文献

This essay contributes a Pacific Islands perspective to the global discussion of “Living Together: Education and Intercultural Dialogue”. Through poetry and prose, this essay traces the impact of the Tongan concept of vaa (values/valued relationships) on learning and language. By invoking UNESCO’s mandate to build peace through education, the concept of vaa is shown to be a key to promoting peace. The challenges and prospects of nurturing peace through international cooperation in education are discussed with examples drawn from the Pacific. Specifically, Tonga’s social and linguistic histories provide avenues for interpreting Pacific educational ideals in relation to Western concepts of knowing and learning. Reflection on cultural literacy in the Pacific context raises deeper questions about the role of educators when working interculturally. Lessons to be learned include the oft-quoted maxim that educators must first learn about their own culture before learning about others’, and before imposing their own pedagogies and curricula on others’ education systems.  相似文献

This study surveyed the current situation of teacher burnout in a sample of 400 teachers from urban junior high school in Shangqiu of Henan Province with scales, and examined the relationship between dimensions of teacher burnout and sources and types of social support they received. The results show that Shangqiu urban junior high school teachers’ emotional exhaustion is serious; gender does not affect the score of burnout significantly; teachers with 1 year job experience recorded significantly lower scores of burnout than others, and teachers who have worked for 6–10 years is second; urban junior high school level affects the score of emotional exhaustion and depersonalization significantly, but does not affect reduced personal accomplishment; social support is most important to enhance feelings of the teacher’s personal accomplishment; among all the sources, supervisor and principal support is the most significant predictor of teacher burnout; emotional support is more significant predictor of teacher burnout than practical support; peer support increases the teacher’s emotional exhaustion. __________ Translated from Jiaoshi Jiaoyu Yanjiu 教师教育研究(Teacher Education Research), 2007, 19(3): 65–71  相似文献

This paper explores a range of therapeutic modalities used by counsellors of children and positions those modalities within Gardner’s theory of multiple intelligences. Research by O’Brien (Gardner’s theory of multiple intelligence and its implications for the counselling of children. Unpublished doctoral dissertation, Queensland University of Technology, Brisbane, Australia, 1999) revealed that by drawing on a combination of preferred intelligences, children were able to enhance the dialogue between the unconscious and conscious, while strengthening the relationship between the counsellor and client. A number of useful counselling approaches are highlighted in working with children, particularly younger children who have not yet developed language sufficient for more formal counselling sessions. Suggestions that assist counsellors to operate across settings are explored.  相似文献

This paper situates the philosophy and politics of partnership in educational development cooperation in the context of wider epistemological and axiological shifts in contemporary social theory. Partnerships in development cooperation are also considered in the light of the alleged failure of international development assistance, a claim that has received much attention with the publication of, among others, William Easterly’s The White Man’s Burden: Why the West’s efforts to aid the rest have done so much ill and so little good (2006) and of Dambisa Moyo’s Dead Aid: Why aid is not working and how there is another way for Africa (2008). Partnership as a development strategy offers one response to these claims, but if shared development objectives and policies, shared ownership, shared decisions about where aid is targeted, shared rights, shared responsibilities, and shared implementation strategies still leave the education development community facing challenges as big as ever, it might be time, the paper concludes, to consider whether the concept of partnership has not been expanded too far as a modality in development cooperation.  相似文献

One hundred years ago, Upton Sinclair, in The Jungle, exposed the deplorable working conditions of eastern European immigrants in the meatpacking houses of Chicago. The backdrop of this article is the new Jungle of the 21st century—the hog plants of the rural Midwest. Here I speak to the lives of the Mexican workers they employ, and, more specifically, the science-learning experiences and aspirations of third-shifters, Jesús and María. I use these students’ stories as an opportunity to examine the take-up, in education, of the concept of hybridity, and, more particularly, to interrogate what I have come to regard as the “third space fetish.” My principle argument is that Bhabha’s understanding of liberatory Third Space has been distorted, in education, through teacher-centered and power-neutral multicultural discourse. I call for a more robust approach to hybridity in science education research, guided by the lessons of possibility and constraint contained in Jesús’ and María’s third-shift third space lives.

A novel polysilicon-assisted silicon-controlled rectifier (SCR) is presented and analyzed in this paper, which is fabricated in HHNEC's 0.18 μm EEPROM process. The polysilicon-assisted SCRs take advantage of polysilicon layer to help bypass electro-static discharge (ESD) current without occupying extra layout area. TLP current-voltage (I-V) measurement results show that given the same layout areas, robustness performance of polysilicon-assisted SCRs can be improved to 3 times of con- ventional MLSCR's. Moreover, one-finger such polysilicon-assisted SCRs, which occupy only 947 μm2 layout area, can undergo 7-kV HBM ESD stress. Results further demonstrate that the S-type I-V characteristics of polysilicon-assisted SCRs are adjustable to different operating conditions by changing the device dimensions. Compared with traditional SCRs, this new SCR can bypass more ESD currents and consumes smaller IC area.  相似文献

This research partially replicated Nilsson and Anderson’s Professional Psychology: Research and Practice (2004) study on training and supervising international students. It investigated the relationships among international counseling students’ training level, acculturation, supervisory working alliance (SWA), counseling self-efficacy (COSE), role ambiguity (RA) and multicultural discussion (MD) in supervision. In the present study (N = 71), two acculturation variables and RA predicted SWA. SWA and MD did not predict COSE, while language use in acculturation did. Training level differences were only associated with COSE. Findings indicate that supervisors should attend to role ambiguity and multicultural issues when supervising international students, including acculturation issues and their impact on students’ performance. Results are discussed against Nilsson and Anderson’s original study and the implications for supervision of international counseling students.  相似文献
