Los mapas conceptuales en la enseñanza : Viejas técnicas con recursos nuevos

Se presenta una investigación acerca del uso y la efectividad de los mapas conceptuales en la enseñanza. La experiencia se realizó en tres universidades cubanas y las materias en las que se emplearon los medios de enseñanza son tan disímiles como: Botánica, Programación Lógica y Estructuras de Datos. Los mapas fueron confeccionados por profesores de vasta experiencia en cada una de las materias y su aplicación en el aula se ha sometido a validaciones estadísticas con resultados satisfactorios. Como parte de la investigación se asocian nuevos recursos a los mapas, entre los que se destacan los agentes inteligentes, que guían el proceso de enseñanza, así como herramientas para la visualización de programas que permiten apreciar el funcionamiento de los algoritmos que se implementen.The present research is about the use and effectiveness of concept maps in teaching. The experiment was conducted in three Cuban universities and educational facilities created were used in subjects as diverse as: Botany, Logic Programming and Data Structures. The systems were developed by teachers with extensive experience and its application in the classroom has undergone successful statistical validations. As part of the research, new resources are associated with the maps, especially the intelligent agents that guide the teaching process, also highlights program visualization tools that allow us to appreciate the performance of the algorithms are implemented.Facultad de Informátic

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
