E‐portfolios in teacher education 2002–2009: the social construction of discourse,design and dissemination     

Carina Granberg 《欧洲师范教育杂志》2010,33(3):309-322

This paper reports on a study of the experiences of teacher educators in the introduction and development of e‐portfolios over an eight‐year period from 2002 to 2009 at a Swedish university. The study was conducted with 67 teacher educators in order to investigate how e‐portfolios have been discussed, designed, used and disseminated during this period. Research methods involved 25 narrative interviews and a questionnaire that was completed by 42 participants. The theoretical framework of Basil Bernstein, particularly his concepts of classification, framing, educational codes and pedagogical devices, was used to analyse the data. The paper presents a discussion of the contextual circumstances in relation to classification, framing and codes that affect the social construction of e‐portfolios. The results point to parallel processes resulting in a variety of discourses and designs of e‐portfolios and highlighting the importance of the social construction of e‐portfolios across the teacher education faculty, rather than merely their implementation.  相似文献   

Perceptions of national identity and attitudes toward immigrants and immigration in Canada and Germany

In the current research, we examined whether promoting an inclusive national ingroup that includes both immigrants and nonimmigrants would improve attitudes toward immigrants and immigration among members of receiving societies. We also determined whether one's nation of citizenship and individual differences in social dominance orientation would moderate the effects. Participants were 126 Canadian students and 282 German students, who completed a measure of social dominance orientation and were then asked to respond to a series of questions designed to heighten the salience of national identity (national identity), promote a national ingroup that includes immigrants (common national ingroup), or irrelevant questions (control). The dependent measures included attitudes toward immigrants and immigration, and subtle prejudice toward immigrants. Results revealed that the manipulation of a common national ingroup successfully promoted more positive attitudes toward immigrants and immigration among higher social dominance oriented Canadian participants, but tended to have detrimental effects on the attitudes of higher social dominance oriented German participants. Results are discussed in terms of the importance of considering the context in which groups are situated, as well as implications for developing strategies to promote harmony between immigrants and members of receiving societies.  相似文献   

Maturity-associated variation in sport-specific skills of youth soccer players aged 13-15 years   总被引：1，自引：1，他引：0

The aim of this study was to estimate the contribution of experience, body size and maturity status to variation in sport-specific skills of adolescent soccer players. The participants were 69 players aged 13.2-15.1 years from three clubs that competed in the highest division for their age group. Height and body mass were measured and stage of pubic hair development was assessed at clinical examination. Years of experience in football was obtained at interview. Six football skill tests were administered: ball control with the body, ball control with the head, dribbling with a pass, dribbling speed, shooting accuracy and passing accuracy. Multiple linear regression analysis was used to estimate the relative contributions of age, stage of sexual maturity, height, body mass and years of formal training in soccer to the six skill tests. Age, experience, body size and stage of puberty contributed significantly but in different combinations to the variance in four of the six skill tests: dribbling with a pass (21%; age, stage of maturity), ball control with the head (14%; stage of maturity, height, body height x body mass interaction), ball control with the body (13%; stage of maturity, years of training) and shooting accuracy (8%; stage of maturity, height; borderline significance, P = 0.06). There were no significant predictors for the tests of dribbling speed and passing accuracy. In conclusion, age, experience, body size and stage of puberty contributed relatively little to variation in performance in four of the six soccer-specific skill tests in adolescent footballers aged 13-15 years.  相似文献   

Development of Pre-Service Mathematics Teachers' Professional Knowledge and Identity in Working with Information and Communication Technology     

João Pedro da Ponte  Hélia Oliveira  José Manuel Varandas 《Journal of Mathematics Teacher Education》2002,5(2):93-115

This paper describes the workundertaken in a course in communication andinformation technology in a pre-service programfor secondary school mathematics teachers. Thiscourse aimed to help pre-service teachersdevelop a positive attitude regarding ICT anduse it confidently. It focused on theexploration of educational software and of theInternet's potential as a means of research andproduction of web sites. We discuss how thepre-service mathematics teachers evaluate theirwork concerning their commitment, difficultiesthey found, learning they identified, andpersonal relationship. We also analyse theeffects of the course on the development oftheir professional knowledge and identity.  相似文献

On the Cross-Country Comparability of Indicators of Socioeconomic Resources in PISA     

Artur Pokropek  Francesca Borgonovi  Carina McCormick 《教育实用测度》2017,30(4):243-258

Large-scale international assessments rely on indicators of the resources that students report having in their homes to capture the financial capital of their families. The scaling methodology currently used to develop the Programme for International Student Assessment (PISA) background indices is designed to maximize within-country comparability over time. However, questions remain on the extent to which alternative scaling methodologies can ensure greater cross-country comparability. Establishing indicators of household resources that are comparable both across countries and over time is fundamental to assessing cross-country differences in socioeconomic inequalities in academic achievement. We use multigroup confirmatory factor analysis for categorical variables to examine the measurement equivalence of the household resource factors across the Organisation for Economic Co-Operation and Development countries that participated in the PISA 2000 and 2012 cycles. We construct a series of alternative measures that use students’ reports on the availability of household resources and compare them to the index of home possessions that is generally used in analyses of PISA data. Our findings show that alternative scaling methodologies can be useful in developing cross-country indicators of socioeconomic status.  相似文献   

Ecological dynamics of continuous and categorical decision-making: The regatta start in sailing

Abstract

Ecological dynamics of decision-making in the sport of sailing exemplifies emergent, conditionally coupled, co-adaptive behaviours. In this study, observation of the coupling dynamics of paired boats during competitive sailing showed that decision-making can be modelled as a self-sustained, co-adapting system of informationally coupled oscillators (boats). Bytracing the spatial–temporal displacements of the boats, time series analyses (autocorrelations, periodograms and running correlations) revealed that trajectories of match racing boats are coupled more than 88% of the time during a pre-start race, via continuous, competing co-adaptions between boats. Results showed that both the continuously selected trajectories of the sailors (12 years of age) and their categorical starting point locations were examples of emergent decisions. In this dynamical conception of decision-making behaviours, strategic positioning (categorical) and continuous displacement of a boat over the course in match-race sailing emerged as a function of interacting task, personal and environmental constraints. Results suggest how key interacting constraints could be manipulated in practice to enhance sailors' perceptual attunement to them in competition.  相似文献   

Gender and socioeconomic status differences in university students’ perception of social support     

Carolina?TinajeroEmail author  Zeltia?Martínez-López  Ma?Soledad?Rodríguez  Ma?Adelina?Guisande  Ma?Fernanda?Páramo 《European Journal of Psychology of Education - EJPE》2015,30(2):227-244

Perceived social support has been shown to be one of the most important protective factors for emerging adult students during their transition to university. However, the relationships between perceived social support and dimensions of gender and family background, which have been shown to affect adjustment to college life, remain unexplored. The current study analyzes the effect of gender, parents’ education, and family income level on social support perceived by Spanish university students. The sample consisted of 575 women and 280 men, of average age 18.02 years (SD?=?0.52) enrolled in the first year of degree courses at the University of Santiago de Compostela (Spain). Three measures were used to assess various facets of perceived social support, namely perceived acceptance, social provisions, and support availability and satisfaction. Gender differences were identified for several perceived social support dimensions; women reported a wider social network, which should cover more diverse needs of social support. In addition, differences related to mother’s education and family income level emerged for the availability of support and perceived acceptance. The results highlight the different role of gender and family background in several dimensions of perceived social support during the transition to emerging adulthood.  相似文献   

Homework and academic achievement across Spanish Compulsory Education

Homework (HW) is one of the most common school-related activities among parents, students and teachers. However, the need to assign HW to students has been extensively debated. The present investigation examines the relationship between specific HW variables (i.e. amount of HW completed, time spent on HW and perceived quality of HW time management) and academic achievement, while controlling for students’ gender and grade level. Participants included 454 students (ranging from 10 to 16?years of age) from three schools in northern Spain. A multivariate analyses of variance and path analyses showed that the amount of HW completed decreased with increased schooling, as did students’ perceived quality of HW time management. Data from hierarchical regression analyses completed by path analyses provided evidence that time spent on HW conjointly with perceived quality of HW time management explains how academic achievement is mediated by the amount of HW completed. These findings deepen the understanding of the complex impact of time spent on HW and on academic achievement.  相似文献   

School Schedules Affect Sleep Timing in Children and Contribute to Partial Sleep Deprivation     

Tâmile Stella Anacleto  Taísa Adamowicz  Laura Simões da Costa Pinto  Fernando Mazzilli Louzada 《Mind, Brain, and Education》2014,8(4):169-174

Although the environmental light/dark cycle is the main zeitgeber for the human species, the social cues seem to be important in the synchronization of circadian rhythms. In Brazil, the existence of two school schedules—one with only morning classes (MG) and other with only afternoon classes (AG)—allows the investigation of the effect of school activities on light exposure and sleep/wake patterns in children. Forty‐seven children wore wrist actimeters for a week for registration of light and sleep data. MG children presented shorter sleep duration on school days than the children from the AG. The results showed that during school days MG children were exposed to bright light earlier in the morning when compared to AG children. Nevertheless, there were no differences in light exposure after sunset. The results reflect the role of school schedules and artificial light in shaping light exposure, and its association with sleep timing in children.  相似文献
