Aragonese Tiles in a Flemish Castle: A Chivalric Gift-Exchange Network in Fifteenth-Century Europe

Excavation of the mid-fifteenth-century castle of Pieter Bladelin, a high-ranking Burgundian official, in the village of Middelburg-in-Flanders, near Bruges (Belgium), has unearthed a remarkable series of blue and white painted and glazed floor tiles. Post-excavation archival and heraldic inquiries into the tiles has led to a deeper understanding of the role that gift exchange of luxury objects played within the diplomatic network of Alfonso V “the Magnanimous”, King of Aragon, and Philip “the Good”, Duke of Burgundy, in shaping a shared chivalric and crusading culture between Burgundy and Aragon. The study demonstrates the added value of the integration of archaeological and historical data in studying economic, political and cultural processes for the later medieval or early modern period.     

A ‘study and research path’ enriching the learning of mechanical engineering

ABSTRACT

Study and research path (SRP) is an inquiry-based teaching format grounded in the Anthropological Theory of the Didactic. One of the specific characteristics of SRP is its task-design basis, which includes explicitly questioning the knowledge at stake in study processes. In this work, we propose general guidelines for the design of SRPs for Engineering courses. We have explored the validity of the SRP methodology for learning Strength of Materials, a key subject in Mechanical Engineering. The use of question–answer maps and the media–milieu dialectics throughout the development of the SRP are discussed, together with the student’s perceptions on the new learning process.     

Students' and teachers' misapplication of le chatelier's principle: Implications for the teaching of chemical equilibrium

The aim of this article was to study the reasons, strategies, and procedures that both students and teachers use to solve some chemical equilibrium questions and problems. Inappropriate conceptions on teaching and a lack of knowledge regarding the limited usefulness of Le Chatelier's principle, with its vague and ambiguous formulation and textbook presentation, may be some of the sources of misconceptions about the prediction of the effect of changing conditions on chemical equilibrium. To diagnose misconceptions and their possible sources, a written test was developed and administered to 170 1st-year university chemistry students. A chemical equilibrium problem, relating to the students' test, was solved by 40 chemistry teachers. First, we ascertained that teacher's conceptions might influence the problem-solving strategies of the learner. Based on this first aspect, our discussion also concerns students' and teachers' misconceptions related to the Le Chatelier's principle. Misconceptions emerged through: (a) misapplication and misunderstanding of Le Chatelier's principle; (b) use of rote-learning recall and algorithmic procedures; (c) incorrect control of the variables involved; (d) limited use of the chemical equilibrium law; (e) a lack of mastery of chemical equilibrium principles and difficulty in transferring such principles to new situations. To avoid chemical equilibrium misconceptions, a specific pattern of conceptual and methodological change may be considered.     

Resolución de problemas y uso de calculadoras

Resumen

El presente trabajo describe un programa para el entrenamiento en la solución de problemas que implican una sola operación básica (suma, resta, multiplicación y división) y presenta resultados de su aplicación a tres sujetos con las operaciones de suma y división. Otro aspecto del trabajo es la investigación del efecto del uso de calculadoras manuales en este tipo de tareas. Los resultados indican que ta aceleración del dominio de la mecánica de las operaciones obtenida con el uso de calculadoras permite a los sujetos un dominio conceptual de los problemas correspondientes a estas operaciones al menos tan bueno como el alcanzado en el caso de problemas y operaciones efectuados manualmente, dentro de los limites de los objetivos contemplados por el programa.     

Does On‐line Distance Higher Education Pay Off for Adult Learners? The Case of the Open University of Catalonia

The increasing opportunities created for adults by on‐line distance universities raise important issues about the payoff to such education. This study uses a unique set of survey data gathered by the Open University of Catalonia (UOC) in 2009 to estimate the earnings gains of the 2000–2003 cohorts of UOC students in six programmes of study over an average six‐year time frame between entering and one year after leaving their studies. It compares their gains with the earnings gains of comparable full‐time workers in the Spanish labour force by age, education level, and gender. The results show that those who studied in UOC's two‐year second‐cycle degree programmes had positive relative earnings gains but those in three‐year first‐cycle degree programmes did not. The study further discusses why adult learners might nevertheless study toward degrees for which payoffs appear low.     

Can schools become an inclusive space shared by all families? Learnings and debates from an action research project in Catalonia

ABSTRACT

This article discusses a 2-year action research project carried out in Catalonia using a sample of seven schools with varying degrees of social and ethnic diversity, focusing on the debate and critical perspectives surrounding the question of family–school relationships. It underlines four considerations, which are seen as symbolic, practical and probable barriers to this partnership: unequal power relationships, diversity and inequality of families, the grammar of schooling and how teachers view their professional identity. We present an action research project that involved the critical participation of the teaching staff in these seven schools and designed to answer the following question: under what conditions could family–school relationships be improved with and for all families, pupils and teachers? The conclusion discusses both the limitations of the critical action research and the lessons learnt from it: (a) the true transformation of the grammar of schooling is a slow and complex process; (b) this process is positive for teachers and makes their work better and easier; (c) the evaluation of constructive critical support is relevant and highly valued; and (d) the assessment of improved daily actions is key to making them visible and sustaining the change process.     

Educar con y para la radio

El taller de radio puede llegar a ser una herramienta altamente significativa que genera conciencia sobre el lenguaje, la música y el propio medio, y la vez tecnológicamente accesible a la actividad escolar. En este artículo se expone un experiencia concreta llevada a cabo a Barcelona desde la Fundación «La Caixa».     

The Internet in face‐to‐face higher education: Can interactive learning improve academic achievement?

Recent research on e‐learning shows that blended learning is more effective than face‐to‐face learning. However, a clear empirical response has not been given to the cause of such improvement. Using a data set of 9044 students at two Catalan universities and a quasi‐experimental approach, two possible hypotheses identified in previous research are studied. The results show that the principal cause of the improvement is not, in itself, the increase in time spent online for educational purposes. Rather, increasing the time devoted to studying online is only useful when it takes place as some form of interactive learning. The educational implications of these results are discussed.     

Draw a Young and an Older Person: Schoolchildren's Images of Older People

The goal of this study was to explore stereotypes of older people as expressed in drawings by a sample of primary school children. Sixty children from fourth to sixth grades (30 boys and 30 girls aged 9 to 12 years) were asked to draw a young man, a young woman, an old man, and an old woman. The drawings were content analyzed. Children in our sample seemed to represent old people in varied or multidimensional ways, indicating, thus, that the image they held about elders was less negative than concluded in similar investigations. In fact, although some drawings had negative content, most pictured a positive—and even friendly—image of old people. Moreover, some of the drawings included both positive and negative traits at the same time. Compared with images of young men and women, those of the elderly seem to be more homogeneous and less complex, since there was more agreement on represented details. Suggestions for future research are proposed.
