A teaching/learning support tool for introductory programming courses

In This work we present a Web-based tool developed with the aim of reinforcing teaching and learning of introductory programming courses. This tool provides support for teaching and learning. From the teacher's perspective the system introduces important gains with respect to the classical teaching methodology. It reinforces lecture and laboratory sessions, makes it possible to give personalized attention to the student, assesses the degree of participation of the students and most importantly, performs a continuous assessment of the student's progress. From the student's perspective it provides a learning framework, consisting in a help environment and a correction environment, which facilitates their personal work. With this tool students are more motivated to do programming

Anàlisi del projecte d’innovació en l’àrea de matemàtiques a la comunitat educativa Creciendo juntos: Parque Paso del Rey, Moreno, Argentina

Resum de les pràctiques desenvolupades l’estiu de 2007 a l’escola Creciendo Juntos, situada a Parque Paso del Rey de Moreno, una ciutat de la perifèria de Buenos Aires, Argentina. Es basa principalment en l’anàlisi d’un projecte d’innovació en l’àrea de matemàtiques què realitzava l’escola

Generació i correcció de problemes combinats

Aquest projecte forma part de la Plataforma ACME (Avaluació Continuada i Millora de l’ensenyament), un entorn virtual de resolució i correcció de problemes amb la finalitat de donar suport a les classes presencials i poder portar a terme una avaluació continuada dels alumnes. El sistema ofereix a l’alumne, a través d’Internet, una col•lecció personalitzada de problemes per assignatura, que a mida que l’alumne els resol, el sistema els corregeix automàticament, proporcionant a l’alumne un sistema de treball continu que l’ajudarà a portar l’assignatura al dia. I al professor li dóna la facilitat de fer el seguiment individualitzat de l’alumne coneixent d’aquesta manera quines són les principals dificultats que troben els alumnes, tant de manera individual com col•lectiva. L’objectiu d’aquest projecte és implementar un nou tipus de problema que ha de permetre al professor elaborar problemes que combinin diferents qüestions de igual o diferent tipologia i que quan l’alumne hagi resolt totes les qüestions, enviï les solucions juntes al sistema perquè aquest retorni el resultat global de la correcció

ACME - Mòdul d'usuaris convidats

El projecte ACME va néixer, l’any 1998, amb la finalitat de millorar la docència de les matemàtiques en els estudis d’Enginyeria Industrial i Enginyeries Tècniques de l’Escola Politècnica de la Universitat de Girona, amb la intenció de buscar la manera de que els alumnes s’impliquessin i participessin més activament en aquesta matèria fent ús de la xarxa com a via de comunicació. El projecte ACME, Avaluació Continuada i Millora de l’Ensenyament, és una eina d’e-learning que té com a objectiu fer una avaluació continuada dels alumnes a través d’uns dossiers personalitzats de problemes que el professor proposa. El sistema permet fer el seguiment, per part del professor, del progrés del conjunt de la classe, o d’un alumne individual, en una assignatura concreta. Això fa que l’ACME tingui un gran valor pedagògic. Els objectius d’aquest projecte final de carrera són els següents:• Desenvolupar un sistema de gestió d’usuaris convidats que ens permeti acceptar o denegar l’accés a usuaris que prèviament han fet una petició per poder utilitzar l’ACME.• Crear un sistema que faciliti la tasca d’assignar als usuaris els temes i els problemes més adients pel seu perfil.• Desenvolupar tot un seguit de millores i ampliacions amb la intenció d’integrar el nou mòdul dins les interfícies existents:Ampliar la interfície d’administració en l’apartat d’usuari amb la opció per gestionar els usuaris convidats. Ampliar la interfície d’administració en l’apartat del quadern de problemes amb les opcions adients per tal de gestionar les assignatures dels convidats.

Changing the epidemiology of carbapenem-resistant Pseudomonas aeruginosa in a Brazilian teaching hospital: the replacement of São Paulo metallo-β-lactamase-producing isolates

In Brazil, carbapenem-resistant Pseudomonas aeruginosa isolates are closely related to the São Paulo metallo-β-lactamase (SPM) Brazilian clone. In this study, imipenem-resistant isolates were divided in two sets, 2002/2003 and 2008/2009, analysed by pulsed field gel electrophoresis and tested for the Ambler class B metallo-β-lactamase (MBL) genes blaSPM-1, blaIMP and blaVIM. The results show a prevalence of one clone related to the SPM Brazilian clone in 2002/2003. In 2008/2009, P. aeruginosa isolates were mostly MBL negative, genetically diverse and unrelated to those that had been detected earlier. These findings suggest that the resistance to carbapenems by these recent P. aeruginosa isolates was not due to the spread of MBL-positive SPM-related clones, as often observed in Brazilian hospitals.

Basic life support teaching in the second year pregraduate medical curriculum: quality of acquisition after 6 months

Purpose of the study: Basic life support (BLS) and automated externaldefibrillation (AED) represent important skills to be acquired duringpregraduate medical training. Since 3 years, our medical school hasintroduced a BLS-AED course (with certification) for all second yearmedical students. Few reports about quality and persistence over timeof BLS-AED learning are available to date in the medical literature.Comprehensive evaluation of students' acquired skills was performedat the end of the 2008 academic year, 6 month after certification.Materials and methods: The students (N = 142) were evaluated duringa 9 minutes «objective structured clinical examination» (OSCE) station.Out of a standardized scenario, they had to recognize a cardiac arrestsituation and start a resuscitation process. Their performance wererecorded on a PC using an Ambuman(TM) mannequin and the AmbuCPR software kit(TM) during a minimum of 8 cycles (30 compressions:2 ventilations each). BLS parameters were systematically checked. Nostudent-rater interactions were allowed during the whole evaluation.Results: Response of the victim was checked by 99% of the students(N = 140), 96% (N = 136) called for an ambulance and/or an AED. Openthe airway and check breathing were done by 96% (N = 137), 92% (N =132) gave 2 rescue breaths. Pulse was checked by 95% (N=135), 100%(N = 142) begun chest compression, 96% (N = 136) within 1 minute.Chest compression rate was 101 ± 18 per minute (mean ± SD), depthcompression 43 ± 8 mm, 97% (N = 138) respected a compressionventilationratio of 30:2.Conclusions: Quality of BLS skills acquisition is maintained during a6-month period after a BLS-AED certification. Main targets of 2005 AHAguidelines were well respected. This analysis represents one of thelargest evaluations of specific BLS teaching efficiency reported. Furtherfollow-up is needed to control the persistence of these skills during alonger time period and noteworthy at the end of the pregraduatemedical curriculum.

Evaluation of an online, case-based interactive approach to teaching pathophysiology

AIM: The aim of this study was to evaluate a new pedagogical approach in teaching fluid, electrolyte and acid-base pathophysiology in undergraduate students. METHODS: This approach comprises traditional lectures, the study of clinical cases on the web and a final interactive discussion of these cases in the classroom. When on the web, the students are asked to select laboratory tests that seem most appropriate to understand the pathophysiological condition underlying the clinical case. The percentage of students having chosen a given test is made available to the teacher who uses it in an interactive session to stimulate discussion with the whole class of students. The same teacher used the same case studies during 2 consecutive years during the third year of the curriculum. RESULTS: The majority of students answered the questions on the web as requested and evaluated positively their experience with this form of teaching and learning. CONCLUSIONS: Complementing traditional lectures with online case-based studies and interactive group discussions represents, therefore, a simple means to promote the learning and the understanding of complex pathophysiological mechanisms. This simple problem-based approach to teaching and learning may be implemented to cover all fields of medicine.

Bridging the Gap: establishing the necessary infrastructure and knowledge for teaching and research in neuroscience in Africa.

Advances in neuroscience research over the last few decades have increased our understanding of how individual neurons acquire their specific properties and assemble into complex circuits, and how these circuits are affected in disease. One of the important motives driving neuroscience research is the development of new scientific techniques and interdisciplinary cooperation. Compared to developed countries, many countries on the African continent are confronted with poor facilities, lack of funding or career development programs for neuroscientists, all of which deter young scientists from taking up neuroscience as a career choice. This article highlights some steps that are being taken to promote neuroscience education and research in Africa.

Plastinated Ethmoidal Region : II. The Preparation and Use of Radio-Opaque Artery Casts in Clinical Teaching.

In endoscopic sinus surgery, knowledge of the course of the internal ethmoida and orbital arteries is crucial.The maxillary and the internal carotid arteries of cadavers were injected with radio-opaque , red colorede silicone. The ethmoidal regions were perpared and plastinated using the standard S10 technique. On some specimens, the ophtalmic and ethmoidal arteries were dissected prior to plastination. The plastinated specimens of the ethmoidal blocks were successfullyintroduced into clinical teaching of sinus anatomy and surgery as an aid to study vaascularization an dits relationship to surgical procedures. Among the advantages of this method are the long-lasting preservation of dissected tissue, visualization of arteries during endoscopic and radiological examinations, and invaluable teachjing and training resources for endoscopic sinus surgery.
