Conservation in Physics Teaching,History of Science and in Child Development

The current work is an exploratory study on the ideas thatstudents in their fourth semester of engineering have about ``conservation'. Wereview the Piagetian position on the importance of conservations in logical operational structures inchild development and we comment upon other current trends in cognitive psychology. We discussbriefly the development of conservations in science during the 17th, 18th and 19th centuries and we pointout the contrast between this and how most textbooks introduce this subject. We have also carried out afirst, tentative analysis of the answers given by a sample of these students to a brief questionnaire about``conservation' and ``non-conservation'.

“Above must be above,and below must be below”: enactment of relational school leadership in Vietnam

Over the past 20 years, relational theories of leadership have gained increased traction in the global discourse in educational leadership. This is observable in the increased frequency with which scholars have begun to construct leadership within the sociocultural and institutional systems of different societies. This study addressed the question, “How is effective school leadership constructed in the multi-faceted education context of modern day Vietnam?” We employed a multi-site case study research design to collect qualitative data from several stakeholder groups in three Vietnamese schools. Analysis centered on describing and synthesizing how principal leadership was constructed in these settings. This study “contextualized school leadership” by describing how leadership themes of managing relationships, preserving harmony, and teacher empowerment were shaped by institutional, political and socio-cultural forces in Vietnamese society. The findings support the importance of contextualizing leadership in order to understand differences in how “effective school leadership” is constructed and understood across different societies.     

The influence of imaging capacity on visual art skills

Imaging is a component of fundamental cognitive processes employed in a variety of cognitive activities. In particular, imaging is of special relevance to artistic skills. As part of our research on the relationships between mental images and the plastic arts, the influence of the imaging capacity in the visual art skills was investigated. Seventy-two fine arts students were administered the Vividness Of Visual Imagery Test and performed tasks testing spatial skill, spatial manipulation skill, and visual memory. Imaging capacity was associated with all three-task scores. We also found that women were more proficient in spatial tasks and spatial manipulation tasks than men. These results lead us to consider future studies with other tests of imaging capacity, with the aim of confirming and generalizing the relation between mental imagery and artistic skills. If the ability to create mental images is connected to artistic skill one would have to take this into account in the teaching of art and in designing programmes for mental image training.

Reasons and mediators in the development and communication of personal digital stories

The expansion of access to devices, as well as the production and publication options in social networks requires a broader definition of the traditional notion of personal digital storytelling. To get a deeper understanding of these practices in the group of adolescents, the objective of this article is to analyze what are the reasons that direct the publications of personal stories and what kind of filters, agents and consequences are articulated in these stories. To do this, the most qualitative part of an investigation on teenagers’ internet publication guidelines is synthesized. Specifically, the results of a semi-structured interview with 12 adolescents between 12 and 20 years are shown. The answers show that the interviewees’ perspective on what a digital story is goes beyond the format and varies depending on the network where it is published and the type of content. Thus, the emphasis and motivation of the publication has shifted from the digital - which has been incorporated with something normal and not differential - towards the personal, focusing the publications on the daily life of young people. An extension and refinement of the public-private dichotomy has been identified, maintaining general privacy guidelines above the dissemination of publications. As for filters, publications are preceded by the widespread use of image modification tools. Finally, the answers show the influence of personal agents, mostly friends and brothers, and technology agents, which determine the relationship between the type of story and the network where it is published.
