La Implantació de l’aprenentatge basat en problemes (APB-APP) en l’educació universitària: anàlisi d’una experiència

En aquest document es detalla l’experiència que s’ha portat a terme en l’Escola Politècnica Superior de la UdG. Concretament en l’assignatura de Fonaments Físics per l’enginyeria en l’àmbit de les titulacions de Disseny Industrial i d’Enginyeria Tècnica Industrial especialitat en Mecànica. L’objectiu general de l’activitat és aportar als alumnes els coneixements bàsics sobre camps elèctrics i teoria de circuits, des dels fonaments conceptuals, passant per l’aplicació dels conceptes en problemes fins a realitzar un esquema del procés, així com la utilització de les noves tecnologies tot aplicant com a tècnica d’aprenentatge basat en problemes: Project Based Learning (APB)

Aprenentatge per problemes

L'Aprenentatge en grup per projectes, una experiència enriquidora

Els canvis a la universitat s’estan produint amb un cert recel per part d’alguns a qui costa acoblar-se als dictats del nou marc que proposa l’EEES. Nosaltres portem anys treballant amb grups i per projectes, dintre dels estudis de Enginyeria del Disseny Industrial i Desenvolupament de Productes de la Universitat de Girona, en les assignatures de Projectes. La nostra experiència és molt positiva i concorda amb tot allò que es ve publicant sobre l’aprenentatge basat en grups i el model de treball sobre projectes. D’aquesta manera aconseguim una bona interacció dels estudiants amb allò que nosaltres volem que aprenguin. L’aprenentatge per projectes (APP, o PBL Project Based Learning) es un conjunt de mètodes de treball, una eina d’instrucció que ajuda tant al docent com a l’alumne en el procés d’ensenyament / aprenentatge però que requereix alguns canvis significatius respecte una classe expositiva o un tradicional treball en grup. Presentem el desenvolupament d’aquests mètodes, on a més hem introduït elements innovadors dintre el que es coneix com autogestió del temps i de l’aprenentatge

GeoNetwork: metadata and cataloging. French (GeoSource) and Swiss (geocat.ch) experiences

GeoNetwork opensource is a standards based, Free and Open Source catalog application to manage spatially referenced resources through the web. It is an OSGEO Project initiated by the Food and Agricultural Organization (FAO). The purpose of this presentation is to illustrate the implementation of such a catalog in national projects in France and in Switzerland. Firstly, we will present you the Geosource project undertaken by BRGM (http://www.brgm.fr/), gathering national and local authorities, national geographic survey, public organisations, associations in order to provide a metadata catalog for french users : definition of french iso profile, support for INSPIRE metadata requirements. Finally, we will present the SwissTopo geocat II project. The purpose of the project is to develop the next generation geospatial catalog for SwissTopo on the basis of GeoNetwork opensource. This both projects underline the closely collaboration between national authorities and the Geonetwork opensource community

A quality-based cost distribution charging scheme for QoS multicast networks

This paper presents a new charging scheme for cost distribution along a point-to-multipoint connection when destination nodes are responsible for the cost. The scheme focus on QoS considerations and a complete range of choices is presented. These choices go from a safe scheme for the network operator to a fair scheme to the customer. The in-between cases are also covered. Specific and general problems, like the incidence of users disconnecting dynamically is also discussed. The aim of this scheme is to encourage the users to disperse the resource demand instead of having a large number of direct connections to the source of the data, which would result in a higher than necessary bandwidth use from the source. This would benefit the overall performance of the network. The implementation of this task must balance between the necessity to offer a competitive service and the risk of not recovering such service cost for the network operator. Throughout this paper reference to multicast charging is made without making any reference to any specific category of service. The proposed scheme is also evaluated with the criteria set proposed in the European ATM charging project CANCAN

Adaptive integral assessment package for the A2UN@ project

This paper presents a first approach of Evaluation Engine Architecture (EEA) as proposal to support adaptive integral assessment, in the context of a virtual learning environment. The goal of our research is design an evaluation engine tool to assist in the whole assessment process within the A2UN@ project, linking that tool with the other key elements of a learning design (learning task, learning resources and learning support). The teachers would define the relation between knowledge, competencies, activities, resources and type of assessment. Providing this relation is possible obtain more accurate estimations of student's knowledge for adaptive evaluations and future recommendations. The process is supported by usage of educational standards and specifications and for an integral user modelling

Classification of sags according to their origin based on the waveform similarity

A statistical method for classification of sags their origin downstream or upstream from the recording point is proposed in this work. The goal is to obtain a statistical model using the sag waveforms useful to characterise one type of sags and to discriminate them from the other type. This model is built on the basis of multi-way principal component analysis an later used to project the available registers in a new space with lower dimension. Thus, a case base of diagnosed sags is built in the projection space. Finally classification is done by comparing new sags against the existing in the case base. Similarity is defined in the projection space using a combination of distances to recover the nearest neighbours to the new sag. Finally the method assigns the origin of the new sag according to the origin of their neighbours

Survival of European patients diagnosed with lymphoid neoplasms in 2000-2002: results of the HAEMACARE project

The European Cancer Registry-based project on hematologic malignancies (HAEMACARE), set up to improve the availability and standardization of data on hematologic malignancies in Europe, used the European Cancer Registry-based project on survival and care of cancer patients (EUROCARE-4) database to produce a new grouping of hematologic neoplasma(defined by the International Classification of Diseases for Oncology, Third Edition and the 2001/2008 World Health Organization classifications) for epidemiological and public health purposes. We analyzed survival for lymphoid neoplasms in Europe by disease group, comparing survival between different European regions by age and sex. Design and Methods Incident neoplasms recorded between 1995 to 2002 in 48 population-based cancer registries in 20 countries participating in EUROCARE-4 were analyzed. The period approach was used to estimate 5-year relative survival rates for patients diagnosed in 2000-2002, who did not have 5 years of follow up. Results: The 5-year relative survival rate was 57% overall but varied markedly between the defined groups. Variation in survival within the groups was relatively limited across European regions and less than in previous years. Survival differences between men and women were small. The relative survival for patients with all lymphoid neoplasms decreased substantially after the age of 50. The proportion of ‘not otherwise specified’ diagnoses increased with advancing age.Conclusions: This is the first study to analyze survival of patients with lymphoid neoplasms, divided into groups characterized by similar epidemiological and clinical characteristics, providing a benchmark for more detailed analyses. This Europe-wide study suggests that previously noted differences in survival between regions have tended to decrease. The survival of patients with all neoplasms decreased markedly with age, while the proportion of ‘not otherwise specified’ diagnoses increased with advancing age. Thus the quality of diagnostic work-up and care decreased with age, suggesting that older patients may not be receiving optimal treatment
