Internal structure of virtual communications in communities of inquiry in higher education: Phases,evolution and participants' satisfaction

This study investigates the phases of development of synchronous and asynchronous virtual communication produced in a community of inquiry (CoI) by analyzing the internal structure of each intervention in the forum and each chat session to determine the evolution of their social, cognitive and teaching character. It also analyzes the participating higher education students' satisfaction with the activities, with the professors' actions, and with themselves. We use a mixed methodology that includes content analysis of the virtual communications by crossing two categorization systems: (1) type of communication according to the model adopted from Garrison, Anderson and Archer (social, cognitive and teaching presence) and (2) phases in the evolution of the communication (initiation, proposal, development, opinion/closing and good‐byes). The data are relevant to the students' satisfaction and grades earned. The results suggest differences in the quantity and content of the communication in each phase and an evolution from social to cognitive elements, ending with social contributions. The students are satisfied with the virtual communications related to both the activities and the professors and evaluate themselves positively.     

mtDNA analysis of the human remains buried in the sarcophagus of Federico II

The sarcophagus containing the remains of Federico II, located in the Cathedral of Palermo (Sicily, Italy), was opened on 1998 to perform a multidisciplinary survey [1]. Next to the remains of Federico II and in close contact with them were laying two other skeletons belonging, according to historical records, to Pietro II di Aragona and to an anonymous person (“The Third Individual”), probably a woman. The bones appeared severely deteriorated. Chemical analysis performed on bone samples excluded that the bodies underwent some kind of embalming process. The analysis of mtDNA from bone samples taken from the three skeletons was successful in only one of the two labs involved. The HVR1-mtDNA sequence (region: from nt 16,035 to nt 16,395), obtained from the bone samples of Federico II and “The Third Individual” appear identical but bear double peaks at the same nucleotide positions, suggesting mixing (i.e. contamination) of different mtDNA types. The HVR1 sequence obtained from the bone sample of Pietro II di Aragona does not present double peaks and differ from the Cambridge Reference Sequence (CRS) at six nucleotide positions. Cloning experiment of the Federico II amplicon demonstrated that the mixed mtDNA types are only two: one identical to CRS, the other identical to the sequence of Pietro II di Aragona. A reconstruction of these data are proposed in the Discussion. Due to the problematic context in which this study was carried out (mixed and deteriorated biological material, failure to replicate results in two different labs), our results and reconstruction can only be offered on a tentative basis. It is hoped that the data presented in this study will reveal useful, for future comparison, if further molecular genetics research will be carried out on the royal dynasties that ruled Sicily in the early centuries of the past millennium.     

A Transactional Approach to Transfer Episodes

In this article we present an analytical framework for approaching transfer episodes—episodes in which participants declare or can be declared to bring prior experience to bear on the current task organization. We build on Dewey’s writings about the continuity of experience, Vygotsky’s ideas of unit analysis, as well as more recent developments in continental philosophy to develop a transactional approach that involves reconceptualizing the notion of experience. In this view, experience is not something that individuals have but an analytical category that denotes the unity of whole persons, their material and social environment, and their changing transactional relations (mutual effects on each other) across time. In the 1st part of the article, we present the theory and contrast it with past and present literature on transfer. In the 2nd part, we develop the methodological implications and analyze an episode of transfer from a technology-enhanced science education curriculum in which students were presented with analogous models of scientific phenomena across different tasks. We describe instances of recognition, of analogical reasoning, and of how students applied theoretical knowledge in terms of transactional units of change. We conclude by discussing implications with regard to further theoretical development and educational practice.     

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.

Case Method in the Teaching of Food Safety

One of the fundamental aims of education is the integration of theory and practice. The case method is a teaching strategy in which students must apply their knowledge to solve real‐life situations. They have to analyze the case described and propose the best possible solution. Although the case may be written, the use of new information and communication technologies can develop the case plan in ways that would achieve greater realism and widen the possibilities for discussion. This paper describes our experience in implementing the case method to teach food safety in the Chair of Hygiene. At first this methodology was used to improve the teaching of good practices in food preparation, later practical work was implemented where small groups of students designed and carried out the microbiological analysis of suspected food. This practical work was presented online as a multimedia activity; students were given face‐to‐face and on‐line tutoring. Evaluation was based both on students’ performance and on a survey they had to answer. More than 92% of students regarded the methodology used for the understanding of the unit as sound. Professors collaboration on providing guidance and multimedia presentation were also positively assessed. The bringing together of face‐to‐face and virtual tasks and small‐group discussion of cases under professors guidance contributed to making good use of the positive aspects of this methodology in order to improve the understanding of problems which do not always have a single answer.     

Proposal for national targets in the framework of the European reduction goal for early school leaving

According to the European Commission’s “Europe 2020” strategy, the early school leaving (ESL) rate in European Union (EU) Member States must be reduced to a maximum of 10 per cent by 2020. This paper proposes a nonlinear distribution method based on dynamic targets for reducing the percentage of early school leavers. The aim of this method is to provide policymakers with alternatives in terms of transferring the EU-wide headline target to individual national targets. Weighting was based on four indicators: ESL rate, unemployment rate, expenditure on education as a percentage of the gross domestic product (GDP), and expenditure on schools per student. As a result, nine possible scenarios for ESL reduction have been constructed for each of the EU Member States in three groups: the whole EU up to June 2013 (EU27), EU Member States which joined before 30 April 2004 (EU15) and EU Member States which joined after 30 April 2004 (EU12). This method allows the European policy to be translated into specific national targets that would converge in the aggregate goal.
