Metodologías activas: un camino hacia la motivación y la creación

El aprendizaje es un foco de luz que ilumina nuestras sendas. Este foco va aumentando a medida que se va aprendiendo, alimentándose de la curiosidad y de la motivación. Esta última es una condición necesaria para que se genera el aprendizaje, sobre todo, en Lengua Extranjera, para ello, se hace imprescindible usar una metodología coetánea, innovadora y coherente con la sociedad de la era digital. Por lo tanto, en este Trabajo Fin de Máster se realiza una armónica combinación de metodologías activas contemporáneas (la gamificación, el Aprendizaje Basado por Proyectos y la clase invertida) para estudiar los beneficios de la pluralidad metodológica en el contexto concreto de la Educación Secundaria Obligatoria mediante su aplicación en dos aulas en un centro educativo público de la provincia de Málaga, así como asentar posibles correlaciones entre el contexto didáctico y la implicación del alumnado. A partir de los resultados obtenidos, se concluye que tanto las actuaciones docentes como la adecuada elección metodológica influyen fundamentalmente en la mejora educativa, en general, y en la motivación del alumnado, en particular

Laboratory preparation of simulated sludge for anaerobic digestion experimentation

Health and environmental factors as well as operational difficulties are major challenges facing the development of an anaerobic digestion process. Some of these problems relate to the use of sludge collected from primary and secondary clarifier units in wastewater treatment plants for laboratory purposes. The present study addresses the preparation of sludge for laboratory purposes by using a mixture that consists of the digested sludge, which is less pathogenic, compared to the collected sludge from the primary or secondary clarifier, and food wastes. The sludge has been tested experimentally for 19 and 32 days under mesophilic conditions. The results show a steady methane production rate from the anaerobic digester which used sludge with a rate of 1.5 l/day and concentration around 60%, with comparatively low H2S gas content (10 ppm). The methane produced from the digester that used only digested sludge decreases during the experimental period

The More You Give the More You Get Back: Moderating Effect of Leadership on Knowledge Sharing in Online Programming Communities

Although there is a significant growth of emerging online programming communities, little succeeded in encouraging members to contribute and share their knowledge. The role of leadership to address the under contribution problem is gaining attention among researchers. This study grounded on path-goal theory to Investigates specifically the role of supportive leadership and achievement oriented leadership behaviour toward knowledge sharing in online programming community (OPC). This introduced model is tested empirically using data collected from 20 online programming communities. The findings from the analysis suggests that self-efficacy and outcome expectancy influences knowledge sharing behaviour of members in online programming community. The finding implied that although online communities are informal in nature, the appropriate type of leadership can boost the members’ efficacy and outcome expectancy toward sharing their knowledge, with the suitable level of autonomy and recognition of members contributions can motivate members to continuously contribute to online programming communities and promoting the sustainability in this platform

Biosorption of Ciprofloxacin (CIP) using the Waste of Extraction Process of Microalgae: The Equilibrium Isotherm and Kinetic Study

       Scientists are investigating the efficacy of different biosorbents for promoting economic and environmental viability in purifying contaminants. Among the primary by-products of biodiesel production is waste microalgae biomass, which has the potential to be used as a cheap biosorbent for the treatment of pollution. In the present study, the biomass left over after extracting the chlorella vulgaris was used to test the potential biosorption of CIP from simulated aqueous solutions. Bisorbent's ability was characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). Analysis with a Fourier Transform Infrared Spectrometer revealed that CIP biosorption occurred mainly at biomass sites containing carboxyl and amino groups. The equilibrium isotherm data and biosorption kinetics were addressed in the present study. The biosorption data match the Langmuir isotherm model, and the maximal biosorption capacity was determined to be 7.56 mg/g. While The pseudo-second-order model accurately described the biosorption kinetic data. Biosorbent regeneration was also studied using two different sodium hydroxide concentrations, the results showing that after desorption, the biosorption capacity decreased from 5.2 to 3.74 and 1.77 (mg/g) using 0.1NaOH and 0.5NaOH, respectively

Experimental investigations of competition and allelopathy in herbaceous plants.

This thesis consists of two parts. Part I describes field investigations carried out to examine the characteristics of the major species present in the herb layer in a range of perennial communities established at various sites in the Sheffield region. At each site quantitative measurements of seasonal changes in shoot biomass were conducted in association with analyses of soil mineral nutrient status and bioassays designed to allow seasonal release of phytotoxins to be detected. From the results of these studies it would appear that dominance in relatively productive and undisturbed vegetation is strongly associated with the capacity to develop a large summer peak in shoot biomass. This pattern is evident in the widely successful grass, Holaus lanatus, although in this species the size of the summer peak was found to vary considerably from year to year. From soil analyses it was apparent that mineral nutrient status plays an important part in determining the types of phenology represented in the vegetation. The results of bioassays conducted on various soils suggested the release of toxins from certain plants. At two sites toxicity appeared to be related to the rapid efflux of organic solutes from deciduous tree litter. Toxic effects were also detected in an area of derelict grassland colonized by Holcaus Lanatus. Evidence of autotoxicity in H. lanatus was obtained from the field and in a garden experiment. The experimental studies in Part II involved attempts to measure the effects of toxin production and competition by H. lanatus upon the growth of species with which H. lanatus is frequently associated in the field. In an attempt to manipulate the vigour and competitive ability of H. lanatus, studies were conducted to measure the influence of temperature and mineral nutrient supply upon a mixed sward. The results revealed a strong capacity in H. lanatus to suppress the vigour of H. lanatus and this ability was only marginally affected by variation in temperature and clipping regime. The results of the laboratory experiments supported the field evidence of toxic effects originating from H. lanatus. A technique was developed which effectively distinguishes between allelopathy and effects resulting from the depletion of mineral nutrients in the soil solution

The Extreme Downflow in the Umbral Light Bridge of the sunspot

Sunspots are the most readily visible manifestations of the interaction of the solar magnetic field with the solar atmosphere and the most prominent tracers of solar magnetic activity. Results of the recent studies based on observation from Hinoddetectedthe presence of extremedownflows in a sunspot light bridgeup to 7.2 kms-1 which is exceed the speed of sound in solar photosphere of about 6 kms-1. The convective downflows and upflows are associated with a strong horizontal outflow directed radially outwards from the sunspot centre. These horizontal flows constitute the famous and mysterious Evershed effect. In the present paperwe studied the asymmetries and wavelength shifts of the FeI lines at 630.25 nm to detect the exiting of the extreme downflows in the sunspot light bridge. Our analysis reveals the presence of extreme downflows in the umbra light bridge of the sunspot of more than 10 km s-1
