Abstract

The vast number of online educational videos available at the moment has generated an emerging area of research concerning their level of suitability. This study considers the epistemic quality of educational videos on mathematics, focusing on the specific content of directly proportional distributions. A qualitative study is used, based on the application of theoretical and methodological tools from the onto-semiotic approach to knowledge and mathematics instruction, principally the notion of epistemic suitability and the identification of algebraic levels. The sample consists of the 31 most popular videos in Spanish on YouTube? on directly proportional distributions. Analysis reveals interesting results on these kinds of resources. In general, it is observed that they are weak in epistemic suitability, which does not seem to affect their level of popularity. Moreover, the existence of videos with inaccurate arguments or incorrect procedures, together with the diversity of algebraic levels used, indicates that teachers should be careful when selecting them and only recommend those that better suit their students’ needs.  相似文献   

A classroom intervention on Spanish grammar and writing: the use of the past tense with secondary school students / La intervención didáctica en el aula sobre gramática y escritura. El saber gramatical y la revisión de textos en el uso de los tiempos verbales del pasado con alumnos de secundaria     

Carmen Rodríguez-Gonzalo 《Cultura y Educación》2013,25(4):879-898

Abstract

This article presents an innovative experience which links grammar teaching with writing, following the premises of the Grammar Didactic Sequences (GDS) with one basic objective: to create a situation in which students learn to reflect on the language they use and are able to use these reflections to improve their writing. The GDS, focused on the use of past tense verb forms, was carried out with fourth-year secondary school students in Spain. This article highlights the difficulties experienced by students when using grammatical concepts as elements to control usage and the importance of revising texts in order to create metalinguistic awareness in a recursive didactic process: from grammar to writing, from writing to grammatical revision, and final version writing.  相似文献   

Lectura y coherencia textual (análisis de un texto narrativo)     

Eduard Aznar  Anna Cros  Lluís Quintana 《Cultura y Educación》2013,25(17):15-28

Los autores proponen la Lingüística Textual para un reenfoque de las actividades de análisis de texto en la enseñanza. Como modelo de aplicación de esa propuesta se expone un caso de análisis textual de una nanación en el que se localizan los mecanismos de coherencia y se generan preguntas de control y ejercicios para que el alumno desarrolle estrategias de lectura.  相似文献

Lenguaje y rendimiento escolar: Un estudio predictivo     

Grace Shum  Angeles Conde  Carmen Díaz  Francisco Martínez  Lorenzo Molina 《Cultura y Educación》2013,25(5):69-79

La incidencia de las competencias lingüistícas del escolar sobre las adquisiciones escolares en las demás áreas del currículum es una realidad que todos los maestros pueden comprobar día a día. En este trabajo se investiga esa incidencia, medida a través de la variable fracaso escolar, y sus resultados podrían permitir extraer algunos principios de intervención educativa precoz en algunos aspectos del lenguaje cruciales para la escolaridad posterior.  相似文献   

¿Usos cotidianos o usos enlatados? Enseñar y evaluar la lectoescritura a sujetos reales y mentes flexibles     

Pablo del Río 《Cultura y Educación》2013,25(19-20):5-24

En el campo del lenguaje y la lectoescritura, la renovación educativa parece estar situándose en la batalla por el diseño abierto y la evaluación informal. En este artículo se propone un modelo teórico para la lectoescritura flexible que pueda soportar las posibilidades que se abren y evitar los inconvenientes que amenazan a los actuales métodos informales de renovación a los que está dedicado el tema central de este número.  相似文献   

Informatica aplicada a la comprensión textual     

Luis Guerra  Juan Martín 《Cultura y Educación》2013,25(13):95-99

Uno de los inconvenientes de los programas didácticos que tratan de desarrollar en el alumno estrategias de comprensión lectora es que, dada la estructura grupal de la clase, deben aplicarse colectivamente cuando su propia naturaleza requeriría la aplicación individual. El ordenador puede conseguir aplicar a toda una clase los mismos modelos de comprensión, pero individualizadamente. En este artículo se expone un modelo experimental.  相似文献   

Learning Processes in Chemistry: Drawing Upon Cognitive Resources to Learn About the Particulate Structure of Matter     

Keith S. Taber  Alejandra García-Franco 《学习科学杂志》2013,22(1):99-142

This article explores 11- to 16-year-old students' explanations for phenomena commonly studied in school chemistry from an inclusive cognitive resources or knowledge-in-pieces perspective that considers that student utterances may reflect the activation of knowledge elements at a range of levels of explicitness. We report 5 themes in student explanations that we consider to derive from implicit knowledge elements activated in cognition. Student thinking in chemistry has commonly been examined from a misconceptions or alternative conceptions/frameworks perspective, in which the focus has been on the status of learners' explicit conceptions. This approach has been valuable, but it fails to explain the origins or nature of the full range of alternative ideas reported. In physics education, the cognitive resources perspective has led to work to characterize implicit knowledge elements—described as phenomenological primitives (p-prims)—that provide learners with an intuitive sense of mechanism. School chemistry offers a complementary knowledge domain because of its focus on the nature of materials and its domination by theoretical models that explain observable phenomena in terms of emergent properties of complex ensembles of “quanticles” (molecules, ions, electrons, atoms, etc.) The themes reported in this study suggest a need to recognize primitive knowledge elements beyond those reported from physics education and suggest that some previously characterized p-prims may be better considered to derive from more broadly applicable intuitive knowledge elements.  相似文献   

The reality of virtual worlds: pros and cons of their application to foreign language teaching     

Paloma Garrido-Iñigo  Francisco Rodríguez-Moreno 《Interactive Learning Environments》2013,21(4):453-470

This article presents our experience of testing the OpenSim platform as a tool in teaching French to 108 tourism students at Universidad Rey Juan Carlos (Madrid, Spain). The article begins with some theoretical reflections on the behaviour of the student when using a virtual platform by means of an avatar, and with our observations of how this doubling of identity is actually the greatest asset of virtual worlds when we intend to apply them to teaching (1. Introduction). Then we move on to present our goals and method of work (2. Aims and methodology) and to analyse the development of the virtual space or sim, setting out the teaching strategies that were employed in each of the islands we created, and which correspond to reading comprehension, listening comprehension and written expression (3. Metaverse design). In order to assess the language learning results, we also devised tests throughout the experiment, which were repeated one month later. The assessment shows that the process of language acquisition is positive (4. Results analysis). Finally, we demonstrate that the rise of virtual worlds has been backed up by psycholinguistic factors, but at the same time their applicability and sustainability depend on technical aspects and very especially on theoretical and pedagogical tenets which are still to be drawn up (5. Conclusions).  相似文献   

A Study of the Use of Ontologies for Building Computer-Aided Control Engineering Self-Learning Educational Software     

Isaías García  Carmen Benavides  Héctor Alaiz  Angel Alonso 《Journal of Science Education and Technology》2013,22(4):589-601

This paper describes research on the use of knowledge models (ontologies) for building computer-aided educational software in the field of control engineering. Ontologies are able to represent in the computer a very rich conceptual model of a given domain. This model can be used later for a number of purposes in different software applications. In this study, domain ontology about the field of lead–lag compensator design has been built and used for automatic exercise generation, graphical user interface population and interaction with the user at any level of detail, including explanations about why things occur. An application called Onto-CELE (ontology-based control engineering learning environment) uses the ontology for implementing a learning environment that can be used for self and lifelong learning purposes. The experience has shown that the use of knowledge models as the basis for educational software applications is capable of showing students the whole complexity of the analysis and design processes at any level of detail. A practical experience with postgraduate students has shown the mentioned benefits and possibilities of the approach.  相似文献
