Resumen Se aborda un análisis del desarrollo del Prácticum de Maestro derivado del plan 2010, particularmente dirigido a valorar los cambios acaecidos en relación con el plan 2000, desde el punto de vista de sus tutores profesionales. La metodología es de tipo cualitativo, con entrevistas a 6 tutores profesionales innovadores de la red de centros de una universidad pública y a los 3 responsables de la materia analizada en ambos planes. Entre los resultados se observa que la percepción sobre las transformaciones operadas en el desarrollo en los centros de esta materia son poco apreciables, así como que la tutela del Prácticum se construye mediante una fuerte relación interpersonal de tutelado y tutor y que está vinculada al tipo de enseñanza que practica. Ello tiene consecuencias en la redefinición futura del Prácticum. Palabas clave: formación del profesorado, tutor de prácticas, Prácticum, grado de educación infantil, grado de educación primaria AbstractThe paper focuses on an analysis of the development of the 2010 practicum program, particularly aimed to assessing the changes in relation to the 2000 plan from the point of view of its professional mentors. The methodology used was qualitative, with interviews to six innovative professional mentors belonging to the network of a public university, 3 of them responsible in the analyzed subject in both plans. Among the results it was showed that the perception of the transformations in the practicum were hardly noticeable, and the practicum mentoring activity was built through strong interpersonal relationship of mentor and student, and linked to the type of teaching practice. This has implications for future redefinition of the practicum.

Objectives: Cochlear implant (CI) users continue to struggle understanding speech in noisy environments with current clinical devices. We have previously shown that this outcome can be improved by using binaural sound processors inspired by the medial olivocochlear (MOC) reflex, which involve dynamic (contralaterally controlled) rather than fixed compressive acoustic-to-electric maps. The present study aimed at investigating the potential additional benefits of using more realistic implementations of MOC processing. Design: Eight users of bilateral CIs and two users of unilateral CIs participated in the study. Speech reception thresholds (SRTs) for sentences in competition with steady state noise were measured in unilateral and bilateral listening modes. Stimuli were processed through two independently functioning sound processors (one per ear) with fixed compression, the current clinical standard (STD); the originally proposed MOC strategy with fast contralateral control of compression (MOC1); a MOC strategy with slower control of compression (MOC2); and a slower MOC strategy with comparatively greater contralateral inhibition in the lower-frequency than in the higher-frequency channels (MOC3). Performance with the four strategies was compared for multiple simulated spatial configurations of the speech and noise sources. Based on a previously published technical evaluation of these strategies, we hypothesized that SRTs would be overall better (lower) with the MOC3 strategy than with any of the other tested strategies. In addition, we hypothesized that the MOC3 strategy would be advantageous over the STD strategy in listening conditions and spatial configurations where the MOC1 strategy was not. Results: In unilateral listening and when the implant ear had the worse acoustic signal-to-noise ratio, the mean SRT was 4 dB worse for the MOC1 than for the STD strategy (as expected), but it became equal or better for the MOC2 or MOC3 strategies than for the STD strategy. In bilateral listening, mean SRTs were 1.6 dB better for the MOC3 strategy than for the STD strategy across all spatial configurations tested, including a condition with speech and noise sources colocated at front where the MOC1 strategy was slightly disadvantageous relative to the STD strategy. All strategies produced significantly better SRTs for spatially separated than for colocated speech and noise sources. A statistically significant binaural advantage (i.e., better mean SRTs across spatial configurations and participants in bilateral than in unilateral listening) was found for the MOC2 and MOC3 strategies but not for the STD or MOC1 strategies. Conclusions: Overall, performance was best with the MOC3 strategy, which maintained the benefits of the originally proposed MOC1 strategy over the STD strategy for spatially separated speech and noise sources and extended those benefits to additional spatial configurations. In addition, the MOC3 strate...

ResumenAnalizamos en este artículo las ideas y opiniones de los educadores de museos sobre las ventajas e inconvenientes de la integración y uso de las Tecnologías de la Información y de la Comunicación en los museos y espacios de presentación del patrimonio. Para el desarrollo de la investigación, en la que han participado 45 educadores de museos, se ha utilizado la metodología por encuesta, analizando los aspectos a tener en cuenta en su integración y utilización, así como las ventajas e inconvenientes que aportan en la realidad de los museos. Los resultados obtenidos muestran opiniones favorables a la integración y uso de las mismas en estos contextos de aprendizaje y una actitud positiva hacia las tecnologías por parte de los educadores de museos. Palabras clave: museos, educadores, TIC, opiniones, creencias AbstractWe analyze in this article the views and opinions of museum educators about the advantages and disadvantages of integration and use of Information Technology and Communication in the museums and heritage presentation. For the development of research, which involved 45 educators from museums, we have used the survey methodology, analyzing the aspects to consider in their integration and use, and the advantages and disadvantages they bring to reality museums. The results show favorable opinions on the integration and use of them in these contexts of learning and a positive attitude towards technology by museum educators.
