An overview of web-based school collaboration: a history of success or failure?     

Anastasia Gouseti 《Cambridge Journal of Education》2013,43(3):377-390

The notion of school collaboration has become widely recognised as an effective means of fostering cultural links and supporting communication between geographically separated schools. As shall be acknowledged in this paper, school collaboration follows on from a long history of collaborative initiatives across the past 50 years. However, the introduction of digital technologies and the internet in the 1990s has raised new challenges and created new opportunities for ‘telecollaboration’ whilst the growth of social media over the past five years is seen to have transformed the ways in which online collaboration is experienced by most end users. Based on a review of the existing body of literature, this paper offers a critical overview of current models of web-based collaborative programmes – attempting to map out the complex nature of school collaboration and consider the actors and factors that can shape successful implementation into educational practices.  相似文献   

Views of Nature and the Human-Nature Relations: An Analysis of the Visual Syntax of Pictures about the Environment in Greek Primary School Textbooks—Diachronic Considerations

This paper explores the function of the visual syntax of images in Greek primary school textbooks. By using a model for the formal analysis of the visual material, which will allow us to disclose the mechanisms through which meanings are manifested, our aim is to investigate the discursive transition relating to the view of nature and the human-nature relationship between two series of natural science textbooks. The model is applied to a total of 635 pictures; 434 coming from the old series of textbooks introduced in the early 1980s and 201 from the new introduced in 2006. The results show that a) no differences in the codes of the visual representation of nature or human-nature relationship were recorded between the two series of textbooks, b) the environmental rhetoric mediated by the pictorial material of the textbooks appears closer to its lay counterpart than to scientific rhetoric, c) both series of textbooks favor a viewer-picture relation which diverges from the epistemological (subject/object) ideas of the romantic worldview and comes closer to the baroque one that depicts the world as non-linear and disconnected, while gives more freedom to the viewer to proceed to subjective interpretations. Thus, we assert that the baroque approach adopted by both series of textbooks does not aim at the initiation of students to the highly conventionalized ways of expression, and ultimately to the formalized and scientific rhetoric. On the contrary, within a constructionist context, the textbooks’ visual mode allows students to equally share power with a quite familiar world.  相似文献   

A Content Analysis of Ethnographic Research Published in Top Criminology and Criminal Justice Journals from 2000 to 2009     

Heith Copes  Anastasia Brown  Richard Tewksbury 《Journal of Criminal Justice Education》2013,24(3):341-359

Despite qualitative research having much to offer to the understanding and prevention of crime, academic research in criminology and criminal justice (CCJ) is primarily quantitative. The relatively limited amount of ethnographic research in the field contributes to difficulties in understanding what represents sound ethnographic designs and the most appropriate ways to present such information. The current study examines the relative frequency with which ethnographic research appears in CCJ journals, and more importantly, the content of these articles. We find that less than 4% of all research published in 15 top CCJ journals use ethnographic methods. We present patterns about the methodological (e.g., sample size, type of data collection, and characteristics of participants) and stylistic (writing style, discussion of coding, and policy recommendations) content of these articles. We conclude with implications for our findings and point to substantive areas of research that may need more attention.  相似文献   

Food Insecurity Among Community College Students: Prevalence and Association With Grade Point Average     

Maya E. Maroto  Anastasia Snelling  Henry Linck 《Community College Journal of Research & Practice》2013,37(6):515-526

This study investigated the prevalence of food insecurity among community college students (N = 301) and the relationship between food insecurity and student grade point average (GPA). It employed a cross-sectional intercept survey, utilizing the U.S. Department of Agriculture’s Household Food Security Survey Module, student self-reported GPA, and demographic variables. The research setting was two community colleges in Maryland—one located in a low income urban area and one located in an affluent suburban area. Results demonstrate that 56% of the students in the overall sample were classified as food insecure. Students at higher risk of food insecurity included those who reported living alone and those who reported being single parents. Students identifying themselves as African American or as multiracial were also at increased risk for food insecurity. Food insecure students were more likely than food secure students to report a lower GPA (2.0–2.49) versus a higher GPA (3.5–4.0). Data suggest that food insecurity is an issue for a large percentage of the community college student sample. Food insecurity may have adverse effects on student academic performance and is a factor to be considered by college administrators, faculty, and students.  相似文献   

Muscle performance following an acute bout of plyometric training combined with low or high intensity weight exercise     

Anastasia G Beneka  Paraskevi K Malliou  Victoria Missailidou  Athanasios Chatzinikolaou  Ioannis Fatouros  Vassilios Gourgoulis 《Journal of sports sciences》2013,31(3):335-343

Abstract

To determine the time course of performance responses after an acute bout of plyometric exercise combined with high and low intensity weight training, a 3-group (including a control group), repeated-measures design was employed. Changes in performance were monitored through jumping ability by measuring countermovement and squat jumping, and strength performance assessment through isometric and isokinetic testing of knee extensors (at two different velocities). Participants in both experimental groups performed a plyometric protocol consisting of 50 jumps over 50 cm hurdles and 50 drop jumps from a 50 cm plyometric box. Additionally, each group performed two basic weight exercises consisting of leg presses and leg extensions at 90–95% of maximum muscle strength for the high intensity group and 60% of maximum muscle strength for the low intensity group. The results of the study suggest that an acute bout of intense plyometric exercise combined with weight exercise induces time-dependent changes in performance, which are also dependent on the nature of exercise protocol and testing procedures. In conclusion, acute plyometric exercise with weight exercise may induce a substantial decline in jumping performance for as long as 72 hours but not in other forms of muscle strength.  相似文献   

An epidemiological study of number processing and mental calculation in Greek schoolchildren     

Koumoula A  Tsironi V  Stamouli V  Bardani I  Siapati S  Annika G  Kafantaris I  Charalambidou I  Dellatolas G  von Aster M 《Journal of learning disabilities》2004,37(5):377-388

The aim of this study was to validate and standardize an instrument for the diagnosis of developmental dyscalculia (mathematics disorder) in a Greek population and to obtain relevant epidemiological data. We used the Neuropsychological Test Battery for Number Processing and Calculation in Children (NUCALC) in a community sample of 240 students ages 7 to 11 years from urban and rural schools. There were no differences between genders in arithmetical performance; however, the effects of grade and socioeconomic level were significant. Prevalence was higher in the rural than in the urban area. A cross-cultural comparison of the Greek data with those obtained with the same instrument in other countries in schoolchildren of the same age was performed.  相似文献   

Polyvocal Play: A Poetic Bricolage of the Why of Our Transdisciplinary Self-Study Research     

Kathleen Pithouse-Morgan  Anastasia P. Samaras 《Studying Teacher Education》2019,15(1):4-18

ABSTRACT

We have come to conceptualize our transdisciplinary, transnational, and transcultural interaction and reciprocal learning through self-study research as polyvocal professional learning. Our conceptualization of polyvocality has made visible how dialogic encounters with diverse ways of seeing, knowing, and doing can deepen and extend professional learning in self-study research. For this collaborative self-study, we created a poetic bricolage composed of frequently used words in three of our published research poems as we asked, “Why? Why does our work together exist? And why should anyone care?” What emerged became an organic abstract of the impetus for our collaborative learning over time. Through inventing a poetic bricolage, we were able to make visible and available how our multiple interests, practices, and methods have come together to support fluid, dialogic co-learning, and re-learning. Discovering the why of our work included unearthing our gravitation toward transdisciplinary scholarship, which offers university faculty a wide range of possibilities for co-learning and co-creativity. Our demonstration of methodological inventiveness in action through poetic bricolage will be useful to others interested in exploring the promise and tensions of plurality, interaction and interdependence, and creative activity in self-study methodology.  相似文献   

Learning from WebQuests     

Martonia Gaskill  Anastasia McNulty  David W. Brooks 《Journal of Science Education and Technology》2006,15(2):133-136

WebQuests are activities in which students use Web resources to learn about school topics. WebQuests are advocated as constructivist activities and ones generally well regarded by students. Two experiments were conducted in school settings to compare learning using WebQuests versus conventional instruction. Students and teachers both enjoyed WebQuest instruction and spoke highly of it. In one experiment, however, conventional instruction led to significantly greater student learning. In the other, there were no significant differences in the learning outcomes between conventional versus WebQuest-based instruction.  相似文献   

Definitions of bullying: a comparison of terms used,and age and gender differences,in a fourteen-country international comparison   总被引：2，自引：0，他引：2

The study of school bullying has recently assumed an international dimension, but is faced with difficulties in finding terms in different languages to correspond to the English word bullying. To investigate the meanings given to various terms, a set of 25 stick-figure cartoons was devised, covering a range of social situations between peers. These cartoons were shown to samples of 8- and 14-year-old pupils (N = 1,245; n = 604 at 8 years, n = 641 at 14 years) in schools in 14 different countries, who judged whether various native terms cognate to bullying, applied to them. Terms from 10 Indo-European languages and three Asian languages were sampled. Multidimensional scaling showed that 8-year-olds primarily discriminated nonaggressive and aggressive cartoon situations; however, 14-year-olds discriminated fighting from physical bullying, and also discriminated verbal bullying and social exclusion. Gender differences were less appreciable than age differences. Based on the 14-year-old data, profiles of 67 words were then constructed across the five major cartoon clusters. The main types of terms used fell into six groups: bullying (of all kinds), verbal plus physical bullying, solely verbal bullying, social exclusion, solely physical aggression, and mainly physical aggression. The findings are discussed in relation to developmental trends in how children understand bullying, the inferences that can be made from cross-national studies, and the design of such studies.  相似文献   

Sexual abuse prevention education for young children: A comparison of teachers and parents as instructors     

Sandy K. Wurtele  Laura C. Kast  Anastasia M. Melzer   《Child abuse & neglect》1992,16(6):865-876

The purpose of this study was to compare teachers and parents as instructors of a personal safety program. One hundred seventy-two Head Start preschoolers were randomly assigned to a personal safety program taught by their teachers, parents, both teachers and parents, or to a general safety control program. Following program participation, children taught the personal safety program by their teachers, parents, or both, demonstrated greater knowledge about sexual abuse and higher levels of personal safety skills compared with those in the control group. Gains in knowledge and skills were maintained at the 5-month follow up. Children taught by their parents showed greater improvements in recognizing inappropriate-touch requests and in their personal safety skills compared with children taught by their teachers, and children who received the program both at home and school were better able to recognize appropriate-touch requests and to demonstrate higher levels of personal safety skills compared with children taught only at school. The emotional costs associated with participating in the program were minimal, and both parents and children rated the program positively. The advantages of home-based instruction for young children are discussed and suggestions for future research are offered.  相似文献
