Efecto de la aplicación de una estrategia de comprensión de lectura en un entorno virtual

Revista Electrónica de Investigación Educativa, Vol. 16, Núm. 3El propósito de esta investigación fue determinar el efecto de la aplicación de una Estrategia Instruccional Integradora para la Comprensión de la Lectura (EIICL), aplicada en un entorno virtual, y diseñada para desarrollar habilidades para la comprensión de textos en Ciencias Sociales y Administración en los estudiantes del segundo semestre de las licenciaturas de Contaduría Pública y Administración de una Institución de Educación Superior. Se trabajó con un diseño correlacional experimental, con un grupo de control y uno experimental, con mediciones antes y después de aplicar la EIICL. Los resultados demuestran que existen diferencias significativas entre los estudiantes que realizaron la lectura de los textos en un entorno virtual con aplicación de la EIICL, en comparación con aquellos que no utilizaron dicha estrategia

Efecto de la estrategia de comprensión de la lectura en un entorno virtual en estudiantes de educación superior

The purpose of this research in a second experiment was to determine the effect of the implementation of an Integrating Instructional Strategy for Reading Comprehension (EIICL), applied in a virtual environment. This strategy was designed to develop skills for reading comprehension of social sciences and administration texts of students of the first semester Accounting and Management degrees in a Mexican public university. The method used was a correlational design with experimental and control group, with measurements before and after the application of EIICL. Results confirmed that there are differences among students who took the reading of the texts, in a virtual environment with application of EIICL, from the students who performed the reading but without the implementation of such strategy.El propósito de esta investigación en un segundo experimento fue determinar el efecto de la aplicación de una estrategia instruccional integradora para la comprensión de la lectura (EIICL) aplicada en un entorno virtual y diseñada para desarrollar habilidades para la comprensión de textos en ciencias sociales y administración en los estudiantes del primer semestre de las licenciaturas en Contaduría y Administración de una universidad pública mexicana.

The Effect of the Application of a Strategy for Reading Comprehension in a Virtual Environment

The purpose of this research was to determine the effect of the application of an Integrating Instructional Strategy for Reading Comprehension (EIICL), implemented in a virtual context and designed to develop comprehension text skills on social sciences and administration of second semester students of Public Accounting and Administration Bachelor's Degree, in a Higher Education Institution. The research was conducted with a correlational design, applied to an experimental group and a control group, with before and after measurements of applying the EIICL. The results confirm that, there are significative differences between the students that made the text reading in a virtual environment with the application of EIICL, from the students that made the reading without the application of such strategy

Modeling Adsorption of CO₂ in Rutile Metallic Oxide Surfaces: Implications in CO₂ Catalysis

CO2 is the most abundant greenhouse gas, and for this reason, it is the main target for finding solutions to climatic change. A strategy of environmental remediation is the transformation of CO2 to an aggregated value product to generate a carbon-neutral cycle. CO2 reduction is a great challenge because of the large C=O dissociation energy, ~179 kcal/mol. Heterogeneous photocatalysis is a strategy to address this issue, where the adsorption process is the fundamental step. The focus of this work is the role of adsorption in CO2 reduction by means of modeling the CO2 adsorption in rutile metallic oxides (TiO2, GeO2, SnO2, IrO2 and PbO2) using Density Functional Theory (DFT) and periodic DFT methods. The comparison of adsorption on different metal oxides forming the same type of crystal structure allowed us to observe the influence of the metal in the adsorption process. In the same way, we performed a comparison of the adsorption capability between two different surface planes, (001) and (110). Two CO2 configurations were observed, linear and folded: the folded conformations were observed in TiO2, GeO2 and SnO2, while the linear conformations were present in IrO2 and PbO2. The largest adsorption efficiency was displayed by the (001) surface planes. The CO2 linear and folded configurations were related to the interaction of the oxygen on the metallic surface with the adsorbate carbon, and the linear conformations were associated with the physisorption and folded configurations with chemisorption. TiO2 was the material with the best performance for CO2 interactions during the adsorption

Efficacy of different trap models of trap tested against <i>Drosophila suzukii</i> flies in three independent tests developed under laboratory cage conditions.

<p>The red-black stripe trap D was used as the reference trap in all tests. Test 1: stimuli of small circular or vertical red-black bands in colorless cup traps A-D; Test 2: inclusion of yellow circles or bands on red-black stripe traps E-D; Test 3: contrasting color effects using transparent or colored dome shaped lids that improved headspace between the access holes in red-black stripe traps H-D. Columns labelled with the same letter were not significantly different for comparisons of responses of each sex or total captures in each experiment (Tukey HSD test, P > 0.05).</p
