Technological, pedagogical and content knowledge in faculty professors of Physical Education

Debido a la invasión de las tecnologías de la información y comunicación (TIC) en la sociedad actual, en el panorama educativo se presentan grandes oportunidades de integración, pero en ocasiones, el profesorado no aprovecha el potencial que éstas ofrecen. El propósito de este estudio fue analizar el conocimiento tecnológico, pedagógico y disciplinar (TPACK) del profesorado formador de futuros docentes de Educación Física necesarios para la efectiva integración de las TIC en el proceso de enseñanza-aprendizaje, teniendo como referencia uno de los modelos más utilizados, el modelo TPACK. Para ello, se administró un cuestionario a 351 docentes universitarios de los Grados en Ciencias de la Actividad Física y el Deporte y Educación Primaria. Se analizaron las diferencias en el TPACK y en la autoeficacia percibida en el uso del ordenador en cuanto al género, edad, a la existencia de formación específica en TIC,así como las relaciones entre sus variables. Los resultados señalan que la aplicación de la tecnología (TCK+TPK+TPACK) de los docentes encuestados se ha visto influenciada por haber realizado acciones específicas formativas en el terreno de la tecnología. Se encontraron diferencias significativas entre el género y la dimensión tecnológica. Además, el conocimiento tecnológico y la autoeficacia percibida en el uso del ordenador fue significativamente mayor en los docentes de menos de 36 años. Por ello, se destaca la necesidad deformación específica sobre la aplicación de las tecnologías en los docentes universitarios, teniendo en cuenta las peculiaridades de los contenidos del área de Educación Física.Due to the invasion of information and communication technologies (ICT) in today’s society, great opportunities for integrationare presented in the educational panorama, but sometimes, teachers don’t take advantage of the potential they offer. The aim of this studywas to analyze the Technological Pedagogical and Content Knowledge (TPACK) framework of the Faculty professors of pre-servicePhysical Education teachers necessary for the effective integration of ICT in the teaching-learning process, taking as a reference theTPACK framework, one of the most common models used to measure it. The method included a questionnaire which was submitted to351 Faculty professors of Bachelor Degree in Physical Education and Sport, and also in Education. TPACK and the computer self-efficacy differences were analyzed in terms of gender, age, the existence of previous ICT training, and the relationship between itsvariables. The results demonstrated that those professors who had undergone a specific training in ITC showed a better application ofthe technology (TCK + TPK + TPACK). Significant differences were identified between gender and technological dimension. Inaddition, the technological knowledge and the computer self-efficacy were significantly higher in teachers under 36 years of age. Giventhe peculiarities of the Physical Education and Sports subject, this study confirms that it is necessary a specific training for the application of technologies in Faculty professor

The Influence of Functional Movement and Strength upon Linear and Change of Direction Speed in Male and Female Basketball Players

The present study aimed to analyse the relationship between functional movement and strength variables upon linear speed (Ls) and change of direction (COD) based on gender. It also aimed to identify the determinants of performance of Ls and COD according to gender. Fifty basketball players (54% female) completed the assessment in which the weightbearing dorsiflexion test, the Y-balance test, the unilateral countermovement jump, the unilateral drop jump, the unilateral triple hop test, Ls and CODs were performed. Speed variables were divided according to time execution into "low-performance" and "high-performance" to establish a comparison between performance groups. Strength variables significantly influenced speed tests’ performance in both genders (p < 0.05). For males, the greater the Ls, the higher the change of direction deficit (p < 0.001). Multiple regression analysis revealed that a long and vertical stretch-shortening cycle (SSC) was the most influential physical ability for speed performance in females (45–65% variance explained; p < 0.001), while in males, a short and horizontal SSC played a significant role (30–61% variance explained; p < 0.022). These results suggest that gender should be considered in programming strength training to improve speed, as each gender will benefit most from the application of different force-orientations and different SSC. Also, the faster the male players were in Ls, the less efficient they were in the COD performance. This is why for men, it would be recommended to perform eccentric exercises along with deceleration and technique drills to improve COD speed.This paper is part of the first author's doctoral thesis carried out in the Doctoral Programme of the University of Huelva (Spain), thanks to the support and funding of the Formación del Profesorado Universitario Programme (FPU22/01057), run by the Ministerio de Ciencias, Innovación y Universidades, Government of Spain.

Estimating soil organic carbon changes in managed temperate moist grasslands with RothC

Temperate grassland soils store significant amounts of carbon (C). Estimating how much livestock grazing and manuring can influence grassland soil organic carbon (SOC) is key to improve greenhouse gas grassland budgets. The Rothamsted Carbon (RothC) model, although originally developed and parameterized to model the turnover of organic C in arable topsoil, has been widely used, with varied success, to estimate SOC changes in grassland under different climates, soils, and management conditions. In this paper, we hypothesise that RothC-based SOC predictions in managed grasslands under temperate moist climatic conditions can be improved by incorporating small modifications to the model based on existing field data from diverse experimental locations in Europe. For this, we described and evaluated changes at the level of: (1) the soil water function of RothC, (2) entry pools accounting for the degradability of the exogenous organic matter (EOM) applied (e.g., ruminant excreta), (3) the month-on-month change in the quality of C inputs coming from plant residues (i.e above-, below-ground plant residue and rhizodeposits), and (4) the livestock trampling effect (i.e., poaching damage) as a common problem in areas with higher annual precipitation. In order to evaluate the potential utility of these changes, we performed a simple sensitivity analysis and tested the model predictions against averaged data from four grassland experiments in Europe. Our evaluation showed that the default model''s performance was 78% and whereas some of the modifications seemed to improve RothC SOC predictions (model performance of 95% and 86% for soil water function and plant residues, respectively), others did not lead to any/or almost any improvement (model performance of 80 and 46% for the change in the C input quality and livestock trampling, respectively). We concluded that, whereas adding more complexity to the RothC model by adding the livestock trampling would actually not improve the model, adding the modified soil water function and plant residue components, and at a lesser extent residues quality, could improve predictability of the RothC in managed grasslands under temperate moist climatic conditions. © 2021 Jebari et al.

Basic Psychological Needs, Class-related Emotions and Satisfaction with Life in Spanish Teachers

The objective of this study was to examine possible antecedents and consequences of teachers’ emotions in the classroom. Based on a cognitive-social perspective and self-determination theory, we examined the relationship between basic psychological needs (BPNs), teachers’ class-related emotions and teachers’ life satisfaction. A sample of 595 teachers from Andalusia (Spain) participated in an online survey. A structural equation model was tested, in which BPNs predicted teachers’ emotions (β = .69; p &lt; .001 positive emotions and β = -.42; p &lt; .001 negative emotions). In addition, BPNs (β = .36; p &lt; .001) and positive emotions (β = .23; p &lt; .001) predicted satisfaction with life. The results show that the fulfilment of work-related BPNs is important to generate positive emotions and well-being in teachers. In addition, the study is the first to provide extensive details on the psychometric properties for assessing teacher emotions with the Achievement Emotions Questionnaire - Teachers (AEQ-T) in a Spanish sample

Monitoring the salt marsh vegetation and flora of the Baixo Vouga Lagunar (Ria of Aveiro, Portugal)

El carácter transicional de la Ría de Aveiro le confiere una riqueza florística singular, integrando comunidades vegetales típicas de las regiones Eurosiberiana y Mediterránea. La implantación del Proyecto Desenvolvimento Agrícola do Vouga (PDAV) va a provocar una modificación de las tasas de encharcamiento y una reducción gradual de la salinidad, factores ecológicos determinantes para muchas de las comunidades halófilas y helofíticas. El presente trabajo pretende contribuir a un mejor conocimiento de la tipología de la vegetación local, que sirva como base para desarrollar un programa de monitorización adecuado que detecte las alteraciones en los patrones espacio- temporales de la vegetación de los sistemas húmedos. Teniendo como objetivo seleccionar los puntos de muestreo donde instalar las parcelas permanentes de monitorización, se realizó una caracterización de la flora y la vegetación a través de trece transectos utilizando una aproximación simplificada al método de Braun- Blanquet. Una vez identificados los tipos de vegetación - en función de su composición florística, corología y ecología - fueron seleccionados al azar inventarios representativos de cada tipo, en los que han sido instaladas dichas parcelas.The transitional biogeographic character of the Ria de Aveiro lagoon area confers it a singular floristic richness, integrating plant communities typical for the Eurosiberian as well as Mediterranean Region. The implementation of the Agricultural Development Plan of the Lower Vouga area (PDAV) in the near future is expected to result in noticeable changes in the tidal submersion regime and a gradual reduction of salinity levels, which are determining ecological factors for many of the halophytic and helophytic plant communities. The present work pretends to contribute to a better knowledge of the local vegetation types and, thereby, to the implementation of an adequate monitoring programme for detecting changes in the spatio-temporal vegetation patterns of the wetlands. With the objective to select the locations for the installation of permanent quadrats, the vegetation of the wetlands was described along 13 transects using a simplified Braun-Blanquet approach. A total of 24 local vegetation types were recognised, 23 of which were selected for the current monitoring programme

Urban soundscape assessment by visually impaired people: First methodological approach in Granada (Spain)

Soundscape assessments by citizens are starting to emerge as a common practice, normally carried out in context by means of soundwalks along selected paths with volunteers. However, when such assessments are carried out, either in situ or in laboratory experiments, visually impaired citizens are not usually involved. To address this question, three soundwalks were carried out in 2020 in the city of Granada, in southern Spain, with the participation of visually impaired people. In this paper, we present the lessons learnt from this research with respect to the methodology issues that have to do with soundwalking and the surveying procedures when people with limited vison are participating, the assessment results, and a comparison with a soundscape evaluation carried out in 2019 without the collaboration of visually impaired people. The results of this preliminary campaign highlight that: (1) Adapting soundscape assessment protocols from standards for visually impaired people is a methodological challenge that requires research attention; (2) Some of the different patterns in the assessment of the soundscape pleasantness between visually impaired and nonvisually impaired participants emerged; (3) The perception of quietness may differ for visually impaired people when orientation and identification are factors that play a role in the acoustic environment evaluation

Assessment of sustainable land management practices in Mediterranean rural regions

Sustainable land management practices can be suitable vehicles to simultaneously address the causes and consequences of land degradation, desertification, and climate change in land managed systems. Here, we assess the potential of a variety of sustainable land management practices that, beyond addressing specific and local issues, assist in tackling Mediterranean Basin-wide land-use challenges. With this work, we aim to highlight those options that simultaneously promote local and regional Basin-wide adaptation. To do that, we developed a novel multi-objective assessment that evaluates the effectiveness of 104 practices adopted within the Mediterranean Basin and documented in the World Overview of Conservation Approaches and Technologies global database. Results indicate that agroforestry and green covers in perennial woody crops can promote multiple ecosystem services while addressing climate change adaptation. We further argue that these two practices together with reforestation, assist in regulating the hydrological cycle of the Basin and in maintaining its multifunctional landscape. Lastly, we reflect on potential biophysical and socio-economic barriers and opportunities associated with the implementation of the three practices. Our approach provides a Basin-wide integrated view that facilitates the coordination of sustainable management strategies across the Mediterranean region. © 2020 Elsevier LtdThe authors would like to thank two anonymous reviewers whose comments helped improve this work.
