Full text linkResumen basado en el de la publicaciónTítulo, resumen y palabras clave en español y en inglésMonográfico con el título: “Competencia digital en la formación del profesorado”Se describe una experiencia realizada con alumnos de enseñanza secundaria y bachillerato, en la que se plantea la elaboración de un artículo de investigación como recurso para generar actitudes positivas ante la ciencia y despertar vocaciones científicas. Se comprobó cómo el alumnado tenía escasos conocimientos acerca de la estructura de los artículos científicos, se estudiaron los diferentes modelos y se planteó la investigación utilizando como patrón la estructura de los mismos. Se emplearon antes y después de la experiencia dos cuestionarios, para evaluar el proceso y un tercero para testear las emociones generadas. El análisis del estudio mostró una disposición positiva del alumnado al aprendizaje de la ciencia mediante este método, porque entre otros aspectos les permitía profundizar en temas que consideraba de su interés.ES
Análisis mixto sobre la docencia del metabolismo celular; el proyecto AQUAROCA
No full textPrograma de Doctorado en Investigación en la Enseñanza y el Aprendizaje de las Ciencias Experimentales, Sociales, Matemáticas y la Actividad Física y DeportivaLa investigación que se presenta, Análisis mixto sobre la docencia del metabolismo celular; el proyecto AQUAROCA, se asienta sobre las siguientes bases: la dificultad que entraña la docencia del metabolismo en el bachillerato, su importancia para la comprensión de los procesos vitales del conjunto de los seres vivos, y la búsqueda y aplicación de un proyecto educativo, que pueda ser empleado en nuestras aulas para mejorar el proceso de aprendizaje del alumnado.
El objeto principal de la investigación es el estudio comparativo entre una metodología tradicional y una metodología activa, el proyecto Aquaroca, fundamentado en los procesos relativos a la acuaponía, y por tanto en la construcción y mantenimiento de pequeños ecosistemas formados por diferentes organismos con diferentes metabolismos.
La hipótesis de trabajo inicial es que, partiendo de la misma base teórica y expuesta por el mismo docente, Aquaroca, ofrece aprendizajes más eficaces y significativos para la comprensión de los conceptos relacionados con el metabolismo que una metodología tradicional.
La metodología de investigación está basada en un diseño cuasi-experimental y transversal, y los datos fueron analizados mediante una metodología de tipo mixta (Cual-Cuantitativa) con el fin de obtener una visión de la realidad mejor y más sustantiva.
Los resultados de la investigación han confirmado la hipótesis principal planteada, esto es, que el alumnado del grupo Aquaroca presenta unos aprendizajes más significativos que los del grupo Control, pero además muestra la gran importancia que adquiere el docente en el proceso de Enseñanza-Aprendizaje, generando una mayor influencia en la elaboración de sus estructuras cognitivas.The research that is presented “Mixed analysis on the teaching of cellular metabolism; The AQUAROCA project” is based on the following foundations: the difficulty involved in teaching metabolism in high school, its importance for understanding the vital processes of all living beings, and the search and application of an educational project, which can be used in our classrooms to improve the learning process of students.
The main object of the research is the comparative study between a traditional methodology and an active methodology, the Aquaroca project, based on processes related to aquaponics, and therefore on the construction and maintenance of small ecosystems made up of different organisms with different metabolisms.
The initial working hypothesis is that, starting from the same theoretical base and exposed by the same teacher, Aquaroca offers more effective and significant learning for the understanding of the concepts related to metabolism than a traditional methodology.
A research methodology based on a quasi-experimental and at the same time cross-sectional design has been used, as it is considered the most suitable in the treatment of the data that were analyzed through a "mixed methodology" (qual-quantitative) to obtain a better and more substantive vision of reality.
The results of the research have confirmed the main hypothesis raised, that is, that the students of the Aquaroca group present more significant learning than that of the Control group, but it also shows the great importance that the teacher acquires in the Teaching-Learning process. They are generating a greater influence in the elaboration of their cognitive structures
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
