The use (and misuse) of PISA in guiding policy reform: the case of Spain

In 2013 Spain introduced a series of educational reforms explicitly inspired by the Programme for International Student Assessment (PISA) 2012 results. These reforms were mainly implemented in secondary education – based upon the assumption that this is where Spain's educational problems lie. This paper questions this assumption by attempting to identify the point where Spanish children fall behind young people in other developed countries. Specifically, by drawing data from multiple international assessments, we are able to explore how cross-national differences in reading skills change as children age. Consideration is given to both the average level of achievement and the evolution of educational inequalities. Our conclusion is that policy-makers have focused their efforts on the wrong part of the education system; educational achievement is low in Spain (and educational inequalities large) long before children enter secondary school. This study therefore serves as a note of caution against simplistic interpretation of the PISA rankings.     

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

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.     

Communist media economics and the consumers: The case of the print media of East Central Europe

Abstract

Entrepreneurship theory complements established approaches to media management research with an alternative frame for viewing media ownership and the media's capacity for content diversity. Established entrepreneurship metrics were applied to media industries in the United States. All media sectors experienced varying rates in the second half of the last century; by the turn of the new century, nearly all were more entrepreneurial than any other U.S. service or manufacturing industry.     

The Impact of Corporate Media News on Market Valuation

This article explores the influence of Web-based corporate reporting on the investors' valuation of companies in the information and communications technology industry. This study compiled 8,111 news items issued in the “Press Releases” tab of the firms' Web sites between January 2003 and April 2005, and analyzed what type of news items affects stock returns. The results show a positive price reaction to news regarding new customers, completion of acquisitions, strategic long-term decisions, and non-technological alliances. In contrast, the results show a negative price reaction to news regarding the launch of new or upgraded products.     

Acceleration Nation: An Investigation into the Violence of Speed and the Uses of Accidents in Iceland

Abstract

There are two starting points from which this paper is constructed: first, Virilio’s observation that the wealth of societies is founded on their dromocratic condition, that the faster societies accelerate their citizens, commercial goods and communication the more political and economic power they have and, second, the links that he traces between technologies of speed and acceleration and the accident. We suggest that Virilio’s ideas on this invite and deserve a closer ethnographic scrutiny than they have so far received, scrutiny that highlights the varied ways in which speed, acceleration and the accident are articulated in different cultural contexts. To this end we offer an investigation into the dromocratic condition, the violence of speed and the uses of accidents in Iceland.     

Progression in Complexity: Contextualizing Sustainable Marine Resources Management in a 10th Grade Classroom

Sustainable management of marine resources raises great challenges. Working with this socio-scientific issue in the classroom requires students to apply complex models about energy flow and trophic pyramids in order to understand that food chains represent transfer of energy, to construct meanings for sustainable resources management through discourse, and to connect them to actions and decisions in a real-life context. In this paper we examine the process of elaboration of plans for resources management in a marine ecosystem by 10th grade students (15–16 year) in the context of solving an authentic task. A complete class (N = 14) worked in a sequence about ecosystems. Working in small groups, the students made models of energy flow and trophic pyramids, and used them to solve the problem of feeding a small community for a long time. Data collection included videotaping and audiotaping of all of the sessions, and collecting the students’ written productions. The research objective is to examine the process of designing a plan for sustainable resources management in terms of the discursive moves of the students across stages in contextualizing practices, or different degrees of complexity (Jiménez-Aleixandre & Reigosa International Journal of Science Education, 14(1): 51–61 2006), understood as transformations from theoretical statements to decisions about the plan. The analysis of students’ discursive moves shows how the groups progressed through stages of connecting different models, between them and with the context, in order to solve the task. The challenges related to taking this sustainability issue to the classroom are discussed.     

The relationship between biology teachers’ understanding of the nature of science and the understanding and acceptance of the theory of evolution

ABSTRACT

Despite the importance of the theory of evolution (TE) to scientific knowledge, a number of misconceptions continue to be found among biology teachers. In this context, the first objective of this study was to identify the impact of professional development programme (PDP) on teachers’ understanding of nature of science (NOS) and evolution and on the acceptance of this theory. Its second objective was to study the relationship among these variables. Three instruments were used to quantify these variables: the Views of the Nature of Science Version D (VNOS D+), the Assessing Contextual Reasoning about Natural Selection (ACORN), and the Measure of Acceptance of Theory of Evolution (MATE). The results indicate that the PDP had a positive impact on teachers, significantly improving their understanding of the NOS and natural selection, as well as their acceptance of the TE. Furthermore, a positive correlation between the understanding of the NOS obtained by teachers in the first part of the PDP and the understanding and acceptance of evolution that these teachers showed at the end of the programme was determined. However, no relationship between an understanding of the NOS and gains in the understanding and acceptance of evolution was found.
