Fostering Distributed Science Learning Through Collaborative Technologies

TACTICS (French and Spanish acronym standing for Collaborative Work and Learning in Science with Information and Communications Technologies) is an ongoing project aimed at investigating a distributed community of learning and practice in which information and communications technologies (ICT) take the role of collaborative tools to support social construction of knowledge. This community is composed of researchers, graduate students, and high-school teachers and their students, from six schools and four universities in Canada and Mexico. It set out in fall 2000 to develop a community around the general topic of integrating concepts in science school subjects. Once a prototype community is established, it can become a terrain where different aspects could be studied. Subsequently, researchers could gradually take a back seat allowing as well as ensuring the autonomy of the school members involved and, thereby, the viability of the learning community. The set up of the proposed prototype distributed science learning community was therefore an essential yet far from trivial first step. This paper discusses the process of setting up the community and the lessons learned.     

Students’ qualification in environmental and sustainability education—epistemic gaps or composites of critical thinking?

In an ‘age of measurement’ where students’ qualification is a hot topic on the political agenda, it is of interest to ask what the function of qualification might implicate in relation to a complex issue as Education for Sustainable Development (ESD) and what function environmental and sustainability issues serve in science education. This paper deals with how secondary and upper secondary teachers in discussions with colleagues articulate qualification in relation to educational aims of ESD. With inspiration from discourse theory, the teachers’ articulations of qualification are analysed and put in relation to other functions of education (qualification, socialisation and subjectification). The results of this study show three discourses of qualification: scientific reasoning, awareness of complexity and to be critical. The discourse of ‘qualification as to be critical’ is articulated as a composite of differing epistemological views. In this discourse, the teachers undulate between rationalistic epistemological views and postmodern views, in a pragmatic way, to articulate a discourse of critical thinking which serves as a reflecting tool to bring about different ways of valuing issues of sustainability, which reformulates ‘matter of facts’ towards ‘matter of concerns’     

Sport education-based irregular teaching unit and students’ physical activity during school recess

Abstract

The aim of the study was to compare the effect of a Sport Education-based irregular teaching unit on the high-school students’ physical activity (PA) during school recess. A sample of 91 adolescents (45 girls) aged 13–16?years old met the exclusion criteria. The six classes were cluster-randomly assigned to the Irregular Sport Education group (Sport Education methodology with competitions in recess), Traditional Sport Education group (Sport Education methodology with competitions in Physical Education lessons), or to the control group (non-intervention). The students’ PA during school recess periods were objectively assessed by GT3X accelerometers. The results of the repeated-measures nested analysis of variance showed that the Sport Education-based irregular teaching unit significantly improved the students’ PA during recesses (p?<?0.001). The competitions phase of the Sport Education model performed at school recesses seems to be a valuable strategy for increasing students’ PA contributing to the achievement of the daily recommendations.     

Knowledge outside the box – sustainable development education in Swedish schools

Background: Sustainable development, as an area of knowledge, appears in several different places in the curriculum and does not fit neatly within the scope of traditional subject areas. In many countries, including Sweden, it has long been upheld as an important tool for increasing understanding of, and dealing with, environmental problems. It is not clear, however, what role education can actually have in the making of a more sustainable future. Even though there are several potential ways for sustainable development to be involved in education, the concept raises many questions when transferred to the school context.

Purpose: This paper investigates how teachers deal with the difficulty of defining and approaching sustainable development as an area of knowledge in Swedish schools.

Sample: This article is based on semi-structured interviews with 40 teachers, 13 of whom were lower secondary school teachers (pupil age 12–15) and 27 were upper secondary school teachers (pupil age 15–18). The study involves teachers in all subjects where sustainable development is a goal in the syllabus. The study is also based on participant observation in one upper secondary class. A total of 17 different schools were involved, from a wide range of locations in Sweden.

Design and methods: The paper builds on qualitative data and the analysis of transcribed interviews and group interviews with teachers in Swedish lower and upper secondary schools. Group interviews, involving three or more people, were conducted on eight occasions. The pupils at an upper secondary school were also observed while they were working on a course called ‘policy and sustainable development’. Data were transcribed and analysed thematically.

Findings: The analysis suggests that, according to the teachers’ experiences, the demands of equivalence and measurability in school have increased and that this affects how sustainable development is approached in teaching and learning. Three main categories of knowledge were identified. The study also presents two representations that model how teachers may approach knowledge about sustainable development – metaphorically termed ‘the Accountant’ and ‘the Adventurer’ – and their different effects on knowledge.

Conclusions: There is a tendency for complex knowledge areas such as sustainable development, which do not fit seamlessly into traditional curriculum subjects, to become oversimplified when translated into teaching situations. According to the representations that we described metaphorically, the teacher, as an accountant, is characterised by ‘knowledge instrumentalism’, which means that teachers administer knowledge and the pupils consume it. In this transactional model, the accountant is also very dependent on external governance and control. Alternatively, the teacher, as an adventurer, is characterised by authority, knowledge and self-control. In this model, knowledge sometimes grows in an unpredictable way in the meeting between people who share common experiences. For adventurers, sustainable development is a matter of commitment and awareness, and it involves an explicit stance. The metaphors can be placed on a continuum which describes how teachers manage the demands of the school system in relation to the knowledge area of sustainable development.     

Promoting entrepreneurship education among university students: design and evaluation of an intervention programme / Fomento de la educación emprendedora entre el alumnado universitario: diseño y evaluación de un programa de intervención

For the consolidation of entrepreneurial education as a field of research, a number of challenges must be met, among them, a better connection between pedagogical objectives and the design of programmes, as well as greater methodological rigour in the evaluation of their impact. With this in mind, this paper analyses the results of an entrepreneurial education programme carried out with a group of students from a Spanish university, contrasting the results with a control group. The results indicate that, after this process, the participating students displayed greater entrepreneurial potential than the group of students that had not participated. However, this difference is due more to a loss of entrepreneurial intention in the group not participating in the programme than to an improvement in the participating students.     

University entrepreneurship in a developing country: The case of the P. Universidad Católica de Chile, 1985–2000

Privatization in higher education is usually understood either as the surge of private institutions or as universities’ growing reliance on private sources of funding or otherwise operating more like firms. Joining the growing literature on university entrepreneurship, this is a case study on the less examined problem of entrepreneurial universities in developing countries. In a period of roughly 15 years, the Pontificia Universidad Católica of Chile, founded in 1888, turned itself from a mostly teaching institution to a research-oriented university, responsible for one-fourth of the Chile’s mainstream scientific output and 40% of all Ph.D.s awarded nationally. Yet, public funding represents today only 17% of its revenues, down from almost 90% in 1972. How such academic development could have occurred as the State withdrew and the market took hold of Chilean higher education after the reforms introduced by the military rule of Augusto Pinochet (1973–1990) is the theme of this work. Universidad Católica’s policies and strategies are described, and the factors contributing to its success, together with their limitations, identified. The case suggests that orientation to the market can be more a means for survival and growth under the pressure of privatization, than a result of a ‘Triple Helix’ strategy of universities, government and industry to generate innovation out of academic knowledge. Secondly, while in the industrialized world, higher education entrepreneurship is associated with knowledge production for economic development (‘Mode 2’), entrepreneurial universities in the context of developing countries may just be finding their way to the academic, disciplinary mode of research.     

Number of Subjects and Time Points Needed for Multilevel Time-Series Analysis: A Simulation Study of Dynamic Structural Equation Modeling

Dynamic structural equation modeling (DSEM) is a novel, intensive longitudinal data (ILD) analysis framework. DSEM models intraindividual changes over time on Level 1 and allows the parameters of these processes to vary across individuals on Level 2 using random effects. DSEM merges time series, structural equation, multilevel, and time-varying effects models. Despite the well-known properties of these analysis areas by themselves, it is unclear how their sample size requirements and recommendations transfer to the DSEM framework. This article presents the results of a simulation study that examines the estimation quality of univariate 2-level autoregressive models of order 1, AR(1), using Bayesian analysis in Mplus Version 8. Three features are varied in the simulations: complexity of the model, number of subjects, and number of time points per subject. Samples with many subjects and few time points are shown to perform substantially better than samples with few subjects and many time points.
