Developing a hypothetical multi‐dimensional learning progression for the nature of matter

We describe efforts toward the development of a hypothetical learning progression (HLP) for the growth of grade 7–14 students' models of the structure, behavior and properties of matter, as it relates to nanoscale science and engineering (NSE). This multi‐dimensional HLP, based on empirical research and standards documents, describes how students need to incorporate and connect ideas within and across their models of atomic structure, the electrical forces that govern interactions at the nano‐, molecular, and atomic scales, and information in the Periodic Table to explain a broad range of phenomena. We developed a progression from empirical data that characterizes how students currently develop their knowledge as part of the development and refinement of the HLP. We find that most students are currently at low levels in the progression, and do not perceive the connections across strands in the progression that are important for conceptual understanding. We suggest potential instructional strategies that may help students build organized and integrated knowledge structures to consolidate their understanding, ready them for new ideas in science, and help them construct understanding of emerging disciplines such as NSE, as well as traditional science disciplines. © 2009 Wiley Periodicals, Inc.

Teachers' memories of disciplinary control strategies from their own school days

This article provides a vision of school disciplinary strategies as provided by childhood school memories of practicing or unemployed teachers. This narrative approach allows us to understand the school and its daily routines and rituals from an insiders' point of view, drawing upon the double perspective teachers employ when reflecting on their own experience as school children. The results of the study demonstrate a wide range of disciplinary practices coinciding with a Foucauldian disciplinary structure – a system of micro‐penalty governing time, activity, behavior, speech, the body, and sexuality. Analyzing the systemic regulation of bodies in schools can uncover institutional meanings and make them available for questioning, perhaps even negotiation. Recognizing the ways in which teachers' roles are inextricably bound with the disciplinary power relations of their institutions can help alleviate frustration and burnout and help teachers make more informed pedagogical decisions.     

A model of equitable and sustainable redistribution of knowledge

Education is one of the pillars in which a Welfare State is effectively based on in order to achieve an equitable distribution of wealth. In contemporary society, knowledge and education are among the most appreciated goods, and everyone should have the right to acquire them, without distinction of gender, race, age, health or religion. From our experience of over 15 years at the Universitat Oberta de Catalunya we can claim that virtual learning makes access to education easier for certain population strata, whereas otherwise, they would be excluded from such a right. A very significant group of students to consider are women with family burdens who, thanks to this kind of education, are able to gain access to higher education for the first time in their lives and at their maturity ages. Another significant group is students with disabilities, for whom virtual education makes it possible to get training in fields for which it would be more difficult to get in the case of the non-virtual university. Geographic factors are also relevant, since virtual education has provided rural areas and other places with poor infrastructures with a chance to gain access to higher education. This brings with it a redistribution of wealth among territories, and also among different social strata with fewer resources and limitations to commute long distances to higher education institutions. Another issue that needs pointing out is virtual communication. As it is asynchronic, it can lead to a high degree of reflection. All these elements enable us to have a virtual discussion about cultural and linguistic issues which have huge educational value.     

Google Scholar,Web of Science,and Scopus: A systematic comparison of citations in 252 subject categories

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage.     

Torrance Test of Creative Thinking: The question of its construct validity

Some cognitive dimensions are internationally considered by psychologists to describe and to assess creativity. For example, (Guilford, P. (1976). Creatividad y Educación. Buenos Aires. Ed. Paidos) and (Torrance, E. P. (1977). Discovery and nurturance of giftedness in the culturally different. Reston, VA: Council on Exceptional Children) suggested fluency, flexibility, originality and elaboration are the main cognitive processes used to define and assess creativity. However, data from several empirical studies did not confirm a factor structure in accordance with such cognitive functions, despite of the wide use of TTCT (Torrance Tests of Creative Thinking) in different countries. In this paper, we present new data collected in Spain and Portugal with TTCT. According to our data, those cognitive functions supposedly present on a subject's performance are not so strong as to explain the variance in scores. Elaboration factors assume some variance explanation, but the main factors are identified with the products in each subtest, suggesting the importance of format, content and demand on TTCT specific tasks. Consequently, we suggest some reflections to amplify the debate concerning the definition of creativity and its evaluation in psychology.     

Health Professionals' Attitudes and Educational Needs Regarding New Food Processing Technologies

ABSTRACT: This project evaluates the attitudes of food and health professionals to 3 new food processing technologies that have been developed to respond to consumer demands such as superior taste, longer shelf life, higher nutritional content, health benefits, and environment‐friendly processing. Educational brochures for high pressure (HP), pulsed electric field (PEF), and ohmic heating (OH) processes were developed based on the current literature and consumer information needs. An internet web survey was conducted to determine information needs of food and health professionals and to assess their satisfaction with the data provided in the educational brochures. Health professionals hold a positive attitude toward HP, OH, and PEF. No negative attitudes or discomfort were reported. More people indicated they were very comfortable with HP than any other technology, and as a consequence this technology received the highest scores of likeliness to be included in health professionals' recommendations.     

Clusters,convergence, and economic performance

This paper evaluates the role of regional cluster composition in regional industry performance. On the one hand, diminishing returns to specialization in a location can result in a convergence effect: the growth rate of an industry within a region may be declining in the level of economic activity of that industry. At the same time, positive spillovers across complementary economic activities can provide an impetus for agglomeration: the growth rate of an industry within a region may be increasing in the “strength” (i.e., relative presence) of related industries. Building on Porter (1998, 2003), we develop a systematic empirical framework to analyze the role of regional clusters – groups of closely related industries operating within a particular region – in the growth of regional industries. We exploit data from the US Cluster Mapping Project to examine the effects of agglomeration within regional clusters after controlling for convergence at the region-industry level. Our findings suggest that industries located in a strong cluster register higher employment and patenting growth. Regional industry growth also increases with the strength of related clusters in the region and with the strength of similar clusters in adjacent regions. We also find evidence of the complementarity between employment and innovation performance in regional clusters: both the initial employment and patenting strength of a cluster have a separate positive effect on the employment and patenting growth of the constituent industries. Finally, we find that new regional industries emerge where there is a strong cluster. These findings are consistent with multiple types of externalities arising in clusters, including knowledge, skills, and input–output linkages.     

Ten years of preanalytical monitoring and control: Synthetic Balanced Score Card Indicator

Introduction

Preanalytical control and monitoring continue to be an important issue for clinical laboratory professionals. The aim of the study was to evaluate a monitoring system of preanalytical errors regarding not suitable samples for analysis, based on different indicators; to compare such indicators in different phlebotomy centres; and finally to evaluate a single synthetic preanalytical indicator that may be included in the balanced scorecard management system (BSC).

Materials and methods

We collected individual and global preanalytical errors in haematology, coagulation, chemistry, and urine samples analysis. We also analyzed a synthetic indicator that represents the sum of all types of preanalytical errors, expressed in a sigma level. We studied the evolution of those indicators over time and compared indicator results by way of the comparison of proportions and Chi-square.

Results

There was a decrease in the number of errors along the years (P < 0.001). This pattern was confirmed in primary care patients, inpatients and outpatients. In blood samples, fewer errors occurred in outpatients, followed by inpatients.

Conclusion

We present a practical and effective methodology to monitor unsuitable sample preanalytical errors. The synthetic indicator results summarize overall preanalytical sample errors, and can be used as part of BSC management system.Key words: Preanalytical phase, errors in laboratory medicine, balanced scorecard, patient safety     

Teachers negotiating discourses of gender (in) equality: the case of equal opportunities reform in Andalusia

This article is focused on the analysis of the narratives produced by a group of teachers, experts in coeducation, while they were discussing their everyday activities. They are responsible for the implementation of a Plan for Gender Equality in public secondary schools in Andalusia (Spain). This study is based on contributions about doing gender view, according to which gender is not an attribute of individuals, but a way of making sense of interactions and practising a complex system as functioning on three levels: sociocultural, interactional, and individual. We use these levels to understand gender culture in schools through teachers’ discourse. Our interest lies particularly in the meanings, contradictions, difficulties, and conflicts experienced by expert teachers in co-education. Our study was based on group discussions with teachers in charge of the plan for equal opportunities between women and men in school settings. Results show teachers’ conflicts about meanings and how they are supposed to apply the Equality Plan. We observed interactional levels during these conflicts and analysed how teachers construct and validate their discourse.     

School in the (im)possibility of future: Utopia and its territorialities

Abstract

Utopia makes itself heard as Raphael voices a critique of who we are and configures that no-where which, paradoxically, we want to reach. We look to Deleuze and Guattari when we say that that critique can be envisioned as resistance to the present. In the passage from no-where to now-here, we revisit the territories of utopia as critique of our times, as a way to approach the question of who we are and who we want to be. In our view, education still rests on the image of a future that unfolds in the encounter with others. Education and its need/potential to enable tomorrows, to invent promises that look to places of desire, spaces that take shape as heterotopias. The notion of utopia is strained at root because defined as a no-where. At school, it is bound to the potential to create new possibilities and alternatives for life in the here and now. In this article, we will grapple with the work we do in university classrooms and in educational institutions in the slums on the outskirts of the city of Buenos Aires as a gateway from which to envision and to problematize the world. From there, we will approach the voices where other possibilities are conquered and other spaces created on the basis of the unpredictable, voices rooted in education and the need for it that produce and produce themselves in the tensions of that (im)possibility. In sum, wording the world as creation of worlds.
