Intervención pedagógica y obstáculos frente a la educación virtual en el área de química de la preparatoria el fuerte

The main purpose of this research is to know the obstacles faced by the teachers of the chemistry area of ​​the El Fuerte preparatory academic unit when intervening pedagogically in a virtual way. Analyzing the forced step from face-to-face education to virtual education at the Autonomous University of Sinaloa, the performance of chemistry teachers to adequately face new emergency situations in the field of education, it was interesting to identify difficulties in the configuration of their learning and therefore in their training, main obstacles faced by both teachers and students in a virtual education. The methodological option in which this research is framed is Qualitative Research, which is distinguished from Quantitative Research because it tries to identify the deep nature of realities, its system of relationships, its dynamic structure and avoids quantification. Using a qualitative approach based on the inductive hypothetical method. The total of the selected sample was characterized by not being probabilistic. After the analysis of results, improvement strategies were proposed to the educational institution.El principal propósito de la esta investigación es conocer los obstáculos a los que se enfrentaron los profesores del área de química de la unidad académica preparatoria El Fuerte al intervenir pedagógicamente de manera virtual.  Analizando el paso obligado de la educación presencial a la educación virtual en la Universidad Autónoma de Sinaloa, el desempeño de los profesores del área de química a enfrentar de manera adecuada nuevas situaciones de emergencia en el ámbito de la educación, fue interesante identificar dificultades en la configuración de sus aprendizajes y por consiguiente en su formación, principales obstáculos que enfrentan tanto profesores como estudiantes en una educación virtual. La opción metodológica en la cual se enmarca la presente investigación es la Investigación Cualitativa, que se distingue de la Investigación Cuantitativa porque trata de identificar la naturaleza profunda de las realidades, su sistema de relaciones, su estructura dinámica y evita la cuanficación. Utilizando un enfoque cualitativo fundamentado en el método hipotético inductivo. El total de la muestra seleccionada se caracterizó por no ser probabilística.  Posterior al análisis de resultados se plantearon estrategias de mejora a la institución educativa

La Educación Virtual y sus Efectos en la Educación Presencial Postpandemia en Estudiantes Universitarios

The main objective of this work was to analyze the impact that virtual education has had on the post-pandemic face-to-face education model in university students, designing a questionnaire for a sample of students from the three main public universities in the State of Sinaloa. A qualitative cut methodology was used, the type of design used is non-experimental, cross-sectional and descriptive. The selection of the sample was carried out through non-probability sampling, which is characterized in that the choice of the sample elements does not depend on probability; but of causes related to the characteristics considered by the investigator. The type of non-probabilistic sampling corresponds to that of Convenience, which involves samples made up of captive informants or volunteers. The results of the research are conclusive that previous virtual education favored the use of new technological tools applied more regularly in the teaching-learning process of the new post-pandemic face-to-face model. On the other hand, virtual education generated learning loss and increased educational disengagement, reflected in the new face-to-face model, ending with the fact that university students mostly prefer the new face-to-face model that has emerged after the pandemic.El presente trabajo tuvo como objetivo principal analizar el impacto que ha tenido la educación virtual sobre el modelo de educación presencial post-pandemia en estudiantes universitarios, diseñandose para ello un cuestionario dirigido a una muestra de estudiantes de las tres principales universidades públicas del Estado de Sinaloa. Se utilizó una metodología de corte cualitativa, el tipo de diseño utilizado es no experimental, transversal descriptivo. La selección de la muestra se llevó a cabo mediante el muestreo no probabílistico, el cual se caracteriza porque la elección de los elementos muestrales no depende de la probabilidad; sino de causas relacionadas con las características consideradas por el investigador. El tipo de muestreo no probabílistico corresponde al de Conveniencia, que se trata de muestras integradas por informantes cautivos o por voluntarios. Los resultados de la investigación son concluyentes en que la educación virtual previa, favoreció el uso de nuevas herramientas tecnológicas aplicadas con mayor regularidad en el proceso enseñanza-aprendizaje del nuevo modelo presencial postpandemia. Por contraparte, la educación virtual generó perdida de aprendizaje y aumento en la desvinculación educativa, reflejándose en el nuevo modelo presencial, finalizando con el hecho de que los universitarios prefieren mayormente el nuevo modelo presencial que ha emergido posterior a la pandemia

Human impacts and aridity differentially alter soil N availability in drylands worldwide

[Aims]: Climate and human impacts are changing the nitrogen (N) inputs and losses in terrestrial ecosystems. However, it is largely unknown how these two major drivers of global change will simultaneously influence the N cycle in drylands, the largest terrestrial biome on the planet. We conducted a global observational study to evaluate how aridity and human impacts, together with biotic and abiotic factors, affect key soil variables of the N cycle.[Location]: Two hundred and twenty-four dryland sites from all continents except Antarctica widely differing in their environmental conditions and human influence.[Methods]: Using a standardized field survey, we measured aridity, human impacts (i.e. proxies of land uses and air pollution), key biophysical variables (i.e. soil pH and texture and total plant cover) and six important variables related to N cycling in soils: total N, organic N, ammonium, nitrate, dissolved organic:inorganic N and N mineralization rates. We used structural equation modelling to assess the direct and indirect effects of aridity, human impacts and key biophysical variables on the N cycle.[Results]: Human impacts increased the concentration of total N, while aridity reduced it. The effects of aridity and human impacts on the N cycle were spatially disconnected, which may favour scarcity of N in the most arid areas and promote its accumulation in the least arid areas.[Main conclusions]: We found that increasing aridity and anthropogenic pressure are spatially disconnected in drylands. This implies that while places with low aridity and high human impact accumulate N, most arid sites with the lowest human impacts lose N. Our analyses also provide evidence that both increasing aridity and human impacts may enhance the relative dominance of inorganic N in dryland soils, having a negative impact on key functions and services provided by these ecosystems.This research is supported by the European Research Council (ERC) under the European Community's Seventh Framework Programme (FP7/2007‐2013)/ERC grant agreement no. 242658 (BIOCOM), and by the Ministry of Science and Innovation of the Spanish Government, grant no.
