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   

Crossed looks: globalisations and curriculum in Guinea-Bissau     

Rui da Silva  Júlio Gonçalves dos Santos  José Augusto Pacheco 《Compare》2015,45(6):978-999

This article focuses on education in Guinea-Bissau in the context of globalisations, examining the concept of globalisation and its relation to education and the curriculum. It focuses on the relatively neglected area of national education policies in Guinea-Bissau, comparing differences and common points of interference/influence of multilateral (international and regional) and bilateral organisations in these policies. Data collection was based on content analysis of a corpus of documents – the Education Act, the document of Portuguese Cooperation Programme, the Education Sector Policy Paper, the Education for All National Plan of Action, and Policy n. 3/2007/CM/UEMOA – and field notes collected from 2009 to 2012. The article argues that there is a tendency for the homogenisation of curriculum policies, at least at the macro-level, due to the different types of pressures coming from international/regional organisations.  相似文献   

Impact of grade retention and school engagement on student intentions to enrol in higher education in Portugal     

Natalie Nóbrega Santos  Vera Monteiro  Carolina Carvalho 《European Journal of Education》2023,58(1):130-150

Grade retention and inequalities that derive from grade retention can influence student school trajectories and careers. Grade retention can discourage students from education, and increase school failure and dropout. This study explored the relationship between grade retention and student intentions to enrol in higher education. We also studied the role of school identification and behavioural engagement in this relationship. The analysis is based on a sample of 1,089 students (grades 6 to 10) from Portugal, one of the European countries with the highest rates of grade retention. We employed multilevel probit regression modelling with random intercept and fixed slopes to explore both the individual and school level effects of grade retention. The analyses showed that retained students had a lower probability of intent to enrol in higher education and that there was a contextual effect of the number of retained students in the school, on students' probability of intent to enrol in higher education. This association was partially explained at the individual level by students' school identification. Retained students presented lower levels of school identification, which in turn results in lower probabilities of enrolling in higher education. Student behavioural engagement was not associated with grade retention nor student intentions. Our findings suggest the need for interventions that foster students' school identification to overcome the adverse effects of grade retention.  相似文献

Workers with disabilities in sheltered employment centres: a training needs analysis     

Pedro Jurado de los Santos 《International Journal of Inclusive Education》2016,20(7):756-769

The work presented is part of a study that the research group CIFO (Research Team in Training for the Labour Market, Autonomous University of Barcelona, Barcelona) has carried out, relating to the training needs analysis and basic competences and skills in the environment of sheltered employment centres (SECs) in Catalonia (this study was undertaken in collaboration with the Coordination of Workshops for People with Mental Disabilities in Catalonia). The analysis and assessment of needs is useful from the perspective of training, as a starting point for planning adapted to the reality of disabled workers in SECs. To do this, various elements such as skills, knowledge and attitudes of individual and social nature have been considered from a systemic approach. By placing ourselves in clearly defined contexts (SECs), we bear in mind the characteristics of workers, the features of the job context, the types of activities performed, the skills related to work activities carried out, the definition of competence profiles required on the basis of the essential skills and the real training needs, through the characteristics of workers and those skills related to the labour activities that are performed as well as the needs for training perceived by workers. Identifying training needs in relation to basic skills and job requirements allows us to meet the challenge, as a trend that supports a competence basis for any worker, of raising general actions that may govern and underlie the training proposals, yet without undermining the specific competences. The importance acquired by what workers themselves have considered about their positioning is understood from the standpoint of its validity, so as to assume conclusions through triangulation processes.  相似文献

Collaboration in ePortfolios with Web 2.0 tools in initial teacher training / La colaboración en eportafolios con herramientas de la Web 2.0 en la formación docente inicial     

Gemma Tur  Santos Urbina 《Cultura y Educación》2016,28(3):601-632

Collaboration is a specific process in the construction of portfolios. In the case of electronic portfolios, Web 2.0 tools make collaboration a key process. The process known as networking refers to the online connection and collaboration with others, which the social web contributes to the literature of electronic portfolios. This research describes and analyses the pilot implementation of an ePortfolio in the Early Childhood degree programme at the Ibiza Campus of the University of the Balearic Islands. The paper presents a qualitative research study which aims to understand collaborative students’ activity from multiple points of view. In view of this, the data collection techniques used are diverse: analysis of work done by students, Likert scale and group discussion. Atlas.ti software has been used to obtain a qualitative analysis of the students’ discourse. In general, the results show positive attitudes, with a gradual increase noticed in the students’ use of the tools and, finally, with collaboration being expressed in peer work, especially in relation to technology. The analysis carried out enables us to observe tensions between open tools, collaboration and assessment. The research has important implications for practice as it allows us to deduce how to improve the collaboration process in ePortfolios thanks to the introduction of Web 2.0 tools.  相似文献   

The role of word recognition,oral reading fluency and listening comprehension in the simple view of reading: a study in an intermediate depth orthography     

Irene Cadime  Bruna Rodrigues  Sandra Santos  Fernanda Leopoldina Viana  Séli Chaves-Sousa  Maria do Céu Cosme  Iolanda Ribeiro 《Reading and writing》2017,30(3):591-611

Empirical research has provided evidence for the simple view of reading across a variety of orthographies, but the role of oral reading fluency in the model is unclear. Moreover, the relative weight of listening comprehension, oral reading fluency and word recognition in reading comprehension seems to vary across orthographies and schooling years. This study aims to examine the direct effects of these three variables on reading comprehension and to test for the existence of indirect effects of word recognition and listening comprehension on reading comprehension via oral reading fluency in European Portuguese, an orthography of intermediate depth. A sample of 264 students was assessed at the end of grades 2 and 4. Structural equation modeling analyses indicated that listening comprehension, word recognition and oral reading fluency predicted reading comprehension in both grade 2 and grade 4. Moreover, the three variables measured in grade 2 predicted later reading comprehension in grade 4. Listening comprehension was always the strongest predictor. Oral reading fluency mediated the relationship between word recognition and reading comprehension, but it was not a mediator variable in the relationship between listening comprehension and reading comprehension. These findings indicate that, similarly to what has been found for other orthographies, the simple view of reading is a valid framework to account for reading comprehension variability in European Portuguese and that interventions to increase reading comprehension levels should focus on word recognition, fluency, and, especially, listening comprehension.  相似文献   

The scientometric world of Keith Pavitt: A tribute to his contributions to research policy and patent analysis     

Martin Meyer  Tiago Santos Pereira  Ove Granstrand 《Research Policy》2004,33(9):1405-1417

Keith Pavitt has made pioneering contributions to the study of science, technology and innovation. This paper aims to examine some of them on the basis of a bibliometric analysis of Keith Pavitt's work and the impact that he has had. First the paper follows how Pavitt's publication profile develops over time. Then we trace his most cited works and explore the sets of references in his papers. Author and journal co-citation maps illustrate the intellectual environment associated with Pavitt and the central role Research Policy played in this context. An analysis of the most frequently cited authors in Research Policy and Scientometrics underlines Keith Pavitt's role as both a shaper of, and a bridge between, science and technology policy and bibliometric analysis.  相似文献   

Guided portfolio writing as a scaffold for reflective learning in in-service contexts: a case study1     

Íris Susana Pires Pereira  Maria Cristina Cristo Parente  Cristina Vieira da Silva 《Teacher Development》2016,20(5):614-630

Language is widely recognized as an inescapable mediating tool for professional learning, and with this text we want to contribute to a better understanding of the particular role that guided writing can play in in-service professional reflective learning. We analysed one pre-school teacher’s written portfolio, the construction of which was guided to scaffold deep thinking about (and the transference of theory into) practice during participation in an in-service program about language education. Our case study shows that the writing process sustained robust learning about professional knowing, doing and learning itself: The teacher elaborated an integrative ethical understanding of the discussed theory, fully experienced newly informed practices and assessed her own learning by using theory to confront her previous knowledge and practices. Throughout the portfolio, the learning stance revealed by her voice varied accordingly. The study illustrates the potential of guided writing to scaffold reflective learning in in-service contexts.  相似文献
