A changed language of education with new actors and solutions: the authorization of promotion and prevention programmes in Swedish schools

This article demonstrates how changes in the language of Swedish education policy have opened up a new social perception of education, in which space has been created for new actors, models and solutions in terms of managing activities in schools. Specifically, it seeks to illustrate how various promotion and prevention programmes have been authorized and disseminated without critical inquiry or resistance in the education sector. To this end, we analyse how the specific, essentially contested concepts of health, value base and communication have been employed in authoritative national documents over the two last decades. For our analysis, we draw on speech act theory, with a focus on linguistic performativity, as we have been interested in analysing how concrete authoritative actors have ‘performed’ various arguments. The analysis helps us to understand how the linguistic force originating from authoritative agencies can be used by different actors as a way to legitimize their arguments and actions. The results demonstrate how different national authorities, as a consequence of their use of the three concepts analysed, have contributed to the establishment of promotion and prevention programmes in education.     

Statistical Models and Inference for the True Equating Transformation in the Context of Local Equating

Based on Lord's criterion of equity of equating, van der Linden (this issue) revisits the so‐called local equating method and offers alternative as well as new thoughts on several topics including the types of transformations, symmetry, reliability, and population invariance appropriate for equating. A remarkable aspect is to define equating as a standard statistical inference problem in which the true equating transformation is the parameter of interest that has to be estimated and assessed as any standard evaluation of an estimator of an unknown parameter in statistics. We believe that putting equating methods in a general statistical model framework would be an interesting and useful next step in the area. van der Linden's conceptual article on equating is certainly an important contribution to this task.     

Lower Secondary Students’ Views in Astrobiology

Astrobiology is, on a profound level, about whether life exists outside of the planet Earth. The question of existence of life elsewhere in the universe has been of interest to many societies throughout history. Recently, the research area of astrobiology has grown at a fast rate, mainly due to the development of observational methods, and the media is frequently reporting on new research findings. International surveys show that astrobiology questions are among those that interest young people the most. The popularity of astrobiology and the way it captures much science content makes it an interesting area for science teaching. However, there is very little research directly focused upon students’ views in astrobiology. The study reported in this paper draws from the answers of 186 Swedish lower secondary students (16 years old) to a questionnaire, with closed and open-ended questions regarding their views of issues in astrobiology. The study was guided by the worldview theory (Cobern 1991; Cobern, Science Education 80(5):579–610, 1996; Cobern, Science and Education 9:219–246, 2000). The results show that even though basic reasoning in astrobiology is known by a majority of the students, there is a considerable number of students, for whom this is not the case. Furthermore, it was found that for all questions, there are students answering in different ways when asked to describe their own view and the view they associate with science researchers. The implications of the study for further research and for the teaching of astrobiology in science class are discussed.     

Discourses on employability: constituting the responsible citizen

In the last couple of decades, there has been a shift from speaking about employment to speaking about employability. The interest in this article is directed at how discourses on employability are mobilised in the wider discursive terrain of governance. How does governance operate, what subject is produced and, more specifically, who is positioned as responsible for the employability of the citizen through such discourses? These questions are addressed by analysing three different kinds of texts: transnational policy documents on lifelong learning and the labour market, a Swedish policy text on in-service training in the health care sector and interviews with employees at six nursing homes for elderly people. A discourse analysis is performed inspired by the concepts of governmentality and the enabling state. The analysis indicates that the individual is constructed as responsible for her/his own employability, and the state and the employer are construed as enablers. However, this is not clear-cut or deterministic as different kinds of texts produce different kinds of positioning. This kind of analysis might help open up a new space for thought and action.     

A Competency Model for Process Dynamics and Control and Its Use for Test Construction at University Level

This study examined students’ competencies in engineering education at the university level. First, we developed a competency model in one specific field of engineering: process dynamics and control. Then, the theoretical model was used as a frame to construct test items to measure students’ competencies comprehensively. In the empirical application, the reliability of the test was examined. The results confirmed the applicability of the theory-based test. Also, associations between students’ competencies and individual characteristics were explored. Students who showed higher competencies could be identified based on their individual characteristics, such as participation in self-assessments. Finally, we demonstrated how to apply the standards of theory-based testing to everyday routines at the university and also highlighted some challenging issues to be considered when implementing theory-based testing in practice. This approach could be valuable: Tests based on theoretically sound models allow for appropriate measurement of students’ competencies in higher education.     

Mapping public support for innovation: A comparison of policy alignment in the UK and France

This paper proposes and tests a three-dimensional model of public support design as a framework to compare public incentives for innovation in firms through time and across countries, and consequently to compare forms of policy alignment of innovation objectives in an economy. Using data on 149 French and British policy programmes from the early 1980s to 2002, this paper shows that policy-makers implement programmes within a different three-dimensional design space in order to align several distinctive objectives and consequently strengthen the impact of governmental measures. Moreover, as the objectives of the national players and policy-makers evolved, the portfolio of innovation policies also evolved in their separate ways. Nevertheless, some similar trends are also observed.     

Phase analysis in maximal sprinting: an investigation of step-to-step technical changes between the initial acceleration,transition and maximal velocity phases

Abstract

The aim of this study was to investigate spatiotemporal and kinematic changes between the initial acceleration, transition and maximum velocity phases of a sprint. Sagittal plane kinematics from five experienced sprinters performing 50-m maximal sprints were collected using six HD-video cameras. Following manual digitising, spatiotemporal and kinematic variables at touchdown and toe-off were calculated. The start and end of the transition phase were identified using the step-to-step changes in centre of mass height and segment angles. Mean step-to-step changes of spatiotemporal and kinematic variables during each phase were calculated. Firstly, the study showed that if sufficient trials are available, step-to-step changes in shank and trunk angles might provide an appropriate measure to detect sprint phases in applied settings. However, given that changes in centre of mass height represent a more holistic measure, this was used to sub-divide the sprints into separate phases. Secondly, during the initial acceleration phase large step-to-step changes in touchdown kinematics were observed compared to the transition phase. At toe-off, step-to-step kinematic changes were consistent across the initial acceleration and transition phases before plateauing during the maximal velocity phase. These results provide coaches and practitioners with valuable insights into key differences between phases in maximal sprinting.     

Naïve and informed views on the nature of scientific inquiry in large-scale assessments: Two sides of the same coin or different currencies?

Many models in the field of epistemic cognition conceptualize students' views as being on a continuum between the poles of naïve and informed views. Against this background, the aim of the present study was to find out whether views on the nature of scientific inquiry (NOSI views) should be conceptualized and quantitatively assessed in a more multiplistic manner, considering naïve and informed views in their own, separate dimensions. Based on a competence model defining three inquiry methods, we developed a Likert-scaled questionnaire containing 10 scales, each assessing one NOSI view. We administered the questionnaire to a sample of 802 students in the lower and upper levels of secondary school. Based on structural equation modeling, the analyses confirmed a 10-dimensional model, distinguishing between each naïve and informed views as the only adequate representation of the data. Latent class analysis and interview data revealed four profiles of NOSI views in the data, which differed with regard to their agreement or disagreement with different naïve and informed views. We interpret these findings as evidence that supports more multiplistic models, with relevance to conceptualizing, measuring, and fostering NOSI views. We derive future directions of nature of science and NOSI research linking basic and applied research using experimental studies.
