Exploring affiliation network models as a collaborative filtering mechanism in e-learning     

Daniel Rodríguez  Miguel Ángel Sicilia  Salvador Sánchez-Alonso  Leonardo Lezcano  Elena García-Barriocanal 《Interactive Learning Environments》2013,21(4):317-331

The online interaction of learners and tutors in activities with concrete objectives provides a valuable source of data that can be analyzed for different purposes. One of these purposes is the use of the information extracted from that interaction to aid tutors and learners in decision making about either the configuration of further learning activities or the filtering of learning resources. This article explores the use of an affiliation network model for such kind of purposes. Concretely, the use of techniques such as blockmodeling – a technique used to derive meaningful patterns of relationships in the network – and the analysis of m-slices – a technique helpful to study cohesion in relationships – are explored as tools to decide on the configuration of topics and/or learner groups. In particular, the results of the case study show that such techniques can be used to (i) filter participants for rearranging groups; (ii) rearrange topics of interest; and (iii) dynamically change the structure of a course. The techniques presented can be considered a case of collaborative filtering based on social network structure.  相似文献   

Science education for sustainability, epistemological reflections and educational practices: from natural sciences to trans-disciplinarity     

Laura Colucci-Gray  Anna Perazzone  Martin Dodman  Elena Camino 《Cultural Studies of Science Education》2013,8(1):127-183

In this three-part article we seek to establish connections between the emerging framework of sustainability science and the methodological basis of research and practice in science education in order to bring forth knowledge and competences for sustainability. The first and second parts deal with the implications of taking a sustainability view in relation to knowledge processes. The complexity, uncertainty and urgency of global environmental problems challenge the foundations of reductionist Western science. Within such debate, the proposal of sustainability science advocates for inter-disciplinary and inter-paradigmatic collaboration and it includes the requirements of post-normal science proposing a respectful dialogue between experts and non-experts in the construction of new scientific knowledge. Such a change of epistemology is rooted into participation, deliberation and the gathering of extended-facts where cultural framings and values are the hard components in the face of soft facts. A reflection on language and communication processes is thus the focus of knowledge practices and educational approaches aimed at sustainability. Language contains the roots of conceptual thinking (including scientific knowledge) and each culture and society are defined and limited by the language that is used to describe and act upon the world. Within a scenario of sustainability, a discussion of scientific language is in order to retrace the connections between language and culture, and to promote a holistic view based on pluralism and dialogue. Drawing on the linguistic reflection, the third part gives examples of teaching and learning situations involving prospective science teachers in action-research contexts: these activities are set out to promote linguistic integration and to introduce reflexive process into science learning. Discussion will focus on the methodological features of a learning process that is akin to a communal and emancipatory research process within a sustainability scenario.  相似文献   

Factors that Influence Students to Become Teachers   总被引：1，自引：0，他引：1  

Constantinos Papanastasiou  Elena Papanastasiou 《Educational Research and Evaluation》2013,19(4):305-316

The purpose of this study was to identify and compare the factors that had influenced students at the Pennsylvania State University and at the University of Cyprus to major in elementary education. A questionnaire was completed by 157 students from PSU and by 176 students from the UC. The factors that were identified were variety of benefits, internal motives, status of the profession, interpersonal influence and academic ability. The factor “internal motives” was the strongest factor that influenced students from the PSU to major in elementary education. The factors which were highly influential for the students of the University of Cyprus to enter the same major, were the “variety of benefits” and the “status of the profession”.  相似文献   

Item Review and the Rearrangement Procedure: Its process and its results     

Elena C Papanastasiou 《Educational Research and Evaluation》2013,19(4):303-321

Permitting item review is to the benefit of the examinees who typically increase their test scores with item review. However, testing companies do not prefer item review since it does not follow the logic on which adaptive tests are based, and since it is prone to cheating strategies. Consequently, item review is not permitted in many adaptive tests. This study attempts to provide a solution that would allow examinees to revise their answers, without jeopardizing the quality and efficiency of the test. The purpose of this study is to test the efficiency of a “rearrangement procedure” that rearranges and skips certain items in order to better estimate the examinees' abilities, without allowing them to cheat on the test. This was examined through a simulation study. The results show that the rearrangement procedure is effective in reducing the standard error of the Bayesian ability estimates and in increasing the reliability of the same estimates.  相似文献   

Modeling teacher empowerment: The role of job satisfaction     

Michalinos Zembylas  Elena C. Papanastasiou 《Educational Research and Evaluation》2013,19(5):433-459

Empowerment is defined and measured in terms of teachers' power to participate in decision-making about teaching and learning conditions. Job satisfaction refers to the level of teacher satisfaction by matters related to these conditions: student achievement, decision-making ability, self-growth, and so on. This research considers the relationship between job satisfaction and teacher empowerment, which includes dimensions of job satisfaction that contribute to teacher empowerment. In particular, it examines the levels of teacher satisfaction in four dimensions (professional growth, decision-making, promotion, and status) and their contribution to the sense of teacher empowerment among Cypriot teachers. The results support the importance of job satisfaction in the construction of teacher empowerment. Specifically, (1) teachers' level of job satisfaction varies depending on the dimension of school life that is focused; (2) teachers' job satisfaction is related to teacher empowerment.  相似文献   

How Russian teachers,mothers and school psychologists perceive internalising and externalising behaviours in children     

Elena Savina  Ludmila Moskovtseva  Oksana Naumenko  Anna Zilberberg 《Emotional and Behavioural Difficulties》2013,18(4):371-385

This study examined the perception of children’s internalising and externalising behaviours by Russian teachers, mothers and school psychologists. The participants rated their agreement about the causes, seriousness and recommended interventions for the problem behaviour of a fictitious girl/boy described in two vignettes. Mixed ANOVAs indicated that all the respondents attributed externalising behaviours to social causes to a greater degree than internalising behaviours. Compared to mothers and psychologists, teachers perceived both types of behaviours as more serious; however, they downplayed their own role in the child’s problems. Psychological help was more popular among school psychologists than among mothers. Correlational analyses demonstrated problem- and respondent-specific associations between casual attributions and recommended interventions. Implications for educational practice are discussed.  相似文献   

Does Russia need sex education? The views of stakeholders in three Russian regions     

Ruzanna Gevorgyan  Elena Schmidt  Martin Wall  Geoffrey Garnett  Rifat Atun  Svetlana Maksimova 《Sex education》2013,13(2):213-226

Objective To investigate the attitudes of the main stakeholders towards the introduction of sex education in schools in Russia.

Design Qualitative semi-structured interview study.

Setting Altai Krai, Volgograd Oblast, Moscow, Russian Federation.

Participants One hundred and fifty-three interviews with Intersectoral HIV/AIDS Committee members, government officials responsible for HIV policies and interventions, non-governmental organisation and private-sector representatives.

Main outcome measures Perception of and attitudes towards the introduction of sex education in schools.

Results Ninety-one per cent of stakeholders welcomed the introduction of sex education in schools and emphasised its importance for a child's personal development, public health, sexually transmitted diseases and HIV/AIDS control, and pregnancy planning. The majority of respondents suggested providing different information for each age and grade. Despite the claimed support of interviewed policy-makers and main HIV stakeholders, there has been no action to introduce sex education. The majority of respondents were of the view that wider positive support through propaganda about health, sex and healthy lifestyle should be gained prior to introducing sex education in schools by addressing the stigma surrounding sexual issues.

Conclusions There was little opposition to the introduction of sex education in Russian schools expressed in our survey, but there are uncertainties regarding curriculum quality, teaching methods and the starting grade of teaching about sex, and there is a need to cover local sensitivities in the territories. These concerns could and should be addressed during curriculum design, development and programme implementation by the federal and local authorities. Wider involvement of educational specialists, peer-adults, health workers, celebrities and religious representatives in discussion of the curriculum could help prevent opposition to its implementation.

Contribution to knowledge Discussion of sex-related topics has been taboo in Russia and there has been little research into opinions on issues related to sex education. The contribution of this research is in gaining theoretical in-depth understanding of the attitudes of the interviewed stakeholders in Russia about the introduction of sex education in schools.  相似文献

The Effect of Media Coverage on Employer Reputation     

Martina Panico  Elena Michel 《Journal of Media Economics》2013,26(4):181-198

A growing body of research examines the formation of employer reputation. One potential driver is media coverage. Using content analysis data for media coverage and survey data, this study examines different dimensions of media coverage, namely, social and functional news and their impacts on employer reputation. Results show that in particular negative functional and social news affect employer reputation, although the impact of negative social news is more indirect and delayed.  相似文献
