Primary and secondary teachers’ conceptions about heritage and heritage education: A comparative analysis

This study describes and analyses the conceptions of primary teachers and secondary teachers of Physics–Chemistry, Biology–Geology and Geography–History with respect to the concept of heritage and its teaching and learning, taking the model of teacher-researcher as the theoretical referent. The data collection instrument used was a questionnaire, designed on the basis of categories that in turn were used for the analysis of the resulting data. The results show a high degree of homogeneity in pedagogic content knowledge, in contrast to the heterogeneity of the conceptions with respect to purely content knowledge.     

The Conceptions of In-service and Prospective Primary School Teachers About the Teaching and Learning of Science

A study was performed to describe and analyze the conceptions about teaching and learning science held by different samples of teachers in Spain. The responses of 265 teachers (107 prospective teachers and 158 active teachers) to items from the Inventory of Scientific and Pedagogical Beliefs (Porlán, 1989) were subjected to multifactorial analysis. The results showed various tendencies in how the teaching/learning process is viewed, ranging from a predominant view based on the transmission-reception of knowledge to a minority constructivist view. There was a greater diversity of viewpoints among the in-service teachers than among the prospective teachers. In both samples, the most representative tendency was learning as appropriation of meanings, followed by a technical view of teaching among the prospective teachers and a more traditional view among the in-service teachers. Finally, some implications for teacher education are discussed.     

Approaches and Methodologies for a Course on History and Epistemology of Physics: Analyzing the Experience of a Brazilian University

This paper is an analysis of inserting history and philosophy of science (HPS) in a physics undergraduate program at a Brazilian university. It is an examination of the approaches and methodologies adopted by professors of a History and Epistemology course. The course aims to have an explicit approach to HPS. The results suggest a concern of the Physics Institute regarding inserting these questions into physics teacher training programs. The study also uncovered that the professors who taught the subject had different visions of HPS.     

The influence of the family,the school,and the group on the environmental attitudes of European students

The attitudes of young people arise from an intense interaction with their social groups of reference, and in this work we examine the extent to which this background conditions the individual environmental attitudes of the young. Using data provided by the PISA 2006 survey for the European Union, we test for the influence of the family, the characteristics of the school, and the social interactions or school peer group on attitudes toward the environment. The existence of social interactions, as well as the important role of family characteristics and school activities, are confirmed. The results allow us to emphasize the importance of the social context of the adolescent, and the need to take this into account as a channel that amplifies the influence of specific environmental education strategies.     

High-throughput study of alpha-synuclein expression in yeast using microfluidics for control of local cellular microenvironment

Microfluidics is an emerging technology which allows the miniaturization, integration, and automation of fluid handling processes. Microfluidic systems offer low sample consumption, significantly reduced processing time, and the prospect of massive parallelization. A microfluidic platform was developed for the control of the soluble cellular microenvironment of Saccharomyces cerevisiae cells, which enabled high-throughput monitoring of the controlled expression of alpha-synuclein (aSyn), a protein involved in Parkinson's disease. Y-shaped structures were fabricated using particle desorption mass spectrometry-based soft-lithography techniques to generate biomolecular gradients along a microchannel. Cell traps integrated along the microchannel allowed the positioning and monitoring of cells in precise locations, where different, well-controlled chemical environments were established. S. cerevisiae cells genetically engineered to encode the fusion protein aSyn-GFP (green fluorescent protein) under the control of GAL1, a galactose inducible promoter, were loaded in the microfluidic structure. A galactose concentration gradient was established in the channel and a time-dependent aSyn-GFP expression was obtained as a function of the positioning of cells along the galactose gradient. Our results demonstrate the applicability of this microfluidic platform to the spatiotemporal control of cellular microenvironment and open a range of possibilities for the study of cellular processes based on single-cell analysis.     

Web and social media usage by museums: Online value creation

This paper contributes to the understanding of online strategies in the context of museums as examples of cultural organisations, an underrepresented sector in the information management literature. It presents a theoretical framework for understanding the online strategies of museums’ use of Web and social media, their sources of online value (efficiency, novelty, lock-in, complementarities) and some measurements of Internet performance, such as the Alexa Internet ranking and the number of followers of museums in social media. This type of analysis has not been conducted before and the findings will help museum curators and managers of other cultural institutions to appreciate the impact of these technologies and to make better informed decisions regarding online strategies and resource allocation. In addition, the results of this research are applicable to similar organisations, such as archives and cultural exhibitions, as well as to other service organisations related to information, education and entertainment activities.     

Acculturation, well-being and classroom behaviour among white British and British Asian primary-school children in the south–east of England: Validating a child-friendly measure of acculturation attitudes

Using a sample of white British and British Asian primary-school children (N = 386, aged 5–11 years), we measured acculturation attitudes (own and perceived outgroup), correlated constructs (ingroup and outgroup affect and identification) and relevant outcomes (self-esteem, classroom demeanour) in a structured interview to validate a customised, child-friendly measure of acculturation attitudes based on Berry's framework. Scale items measuring desire for culture maintenance and intergroup contact loaded onto the predicted factors, were internally reliable and showed concurrent validity with affect and identification. The predictive utility of measures was demonstrated in associations between children's acculturation attitudes (or perceived discrepancies with those of the outgroup) and outcomes such as self-esteem and teacher ratings of emotional symptoms.
