¿Cuál es la alternativa cuando uno se plantea el problema de que el niño aprende cosas triviales que le interesan y no aprende cosas importantes que no le interesan? ¿Son tan triviales las triviales? ¿Son tan importantes las que no le interesan?Parece que la incorporación de los medios a la escuela está ayudando a establecer ese necesario puente entre el curriculum formal y el informal, entre la escuela y el mundo real. El caso de la prensa, alentado por su obvia relación con el proceso de lectoescritura, ha llevado también a extender el experimento al impulso que el uso de los medios en clase puede dar al aprendizaje de los diversos códigos y lenguajes.Este artículo revisa en la primera parte algunos conceptos básicos para entender el papel de los medios en la educación, sobre todo en relación con el sentido de ésta para el alumno y ofrece en la segunda parte una serie de propuestas concretas para su integración en el curriculum de la reforma y para la aplicación práctica. 相似文献

Se presenta aquí un caso de aplicación del «análisis del discurso» para la evaluación, los intercambios lingüísticos de profesores y alumnos en clase y, de este modo, de la calidad didáctica de las clases de lengua. El modelo se propone como técnica para la autoevaluación y optimización de las estrategias de instrucción… 相似文献

La gran muralla del ordenador para los educadores ha sido que imponía el juego que Goethe achacaba a los matemáticos: lo traducen todo a su idioma y ya se trata de algo distinto inasequible para la generalidad de los mortales. La informática separaba a los educadores de la informática. Los lenguajes «de autor» que traducen las posibilidades del ordenador a pautas de acción expresadas en códigos sencillos y naturales y que sirven para producir cursos, lecciones o didácticas fácilmente, permiten por primera vez que el educador pase a ser protagonista y no el anfitrión de una visita inoportuna, del papel del ordenador en educación. 相似文献

AbstractIn the context of a changing society, strategies are required to eradicate the phenomenon of antisocial behaviour. The Aprender a Convivir universal prevention programme tries to provide such a response. This study attempts to test the effectiveness of the programme through a quasi-experimental long-term study carried out over three years in some nursery schools. Of the students who participated in this study (N = 784), those from the experimental group showed significant increases in social competence compared to the control group, and behavioural problems decreased, albeit not in any significant way. To draw conclusions about the effectiveness of the programme, further improvements are proposed to the design of the study. 相似文献

La enseñanza de las matemáticas ha estado tradicionalmente condicionada por una visión universalista de las capacidades mentales, que ha tenido poco en cuenta que el lenguaje matemático no es una abstracción aprioristica y acontextual, sino que pasa por la utilización de «metáforas» instrumentales utilizadas por los propios matemáticos a lo largo de la historia y escamoteada al niño en la escuela. En este artículo se expone un diseño didáctico en que se hace una apuesta fuerte por una enseñanza de la geometría que recoja los instrumentos culturales (las «metáforas» materiales) presentes en nuestro entorno y los utilice en sus diseños como mediadores entre la realidad y los conceptos. 相似文献

AbstractThis paper presents a study of service learning (SL) as a methodology to facilitate the development of media competence in future teachers. The SL methodology fulfils a training and service need for two different populations: in our case, a preschool/primary school and students from the Bachelor’s in Education degrees at the Universidad de Jaén. The study involved 193 university students who carried out 63 projects involving new technologies. The goal of these projects was to produce materials to be used on smartboards, advertising materials, picture-reading materials or multimedia resources, among others. These materials were designed and created in the university classes as a part of the practical sessions of a course and were then given away to be used at a preschool/primary school. At the end of the project, the university students filled out a questionnaire that required them to compare SL to traditional activities in terms of how well each type of practice helps them to achieve the 20 competences of the course. The results show that students recognize the value of the SL methodology more than traditional practice, which suggests the relevance of this methodology for university students. 相似文献

One of the fundamental aims of education is the integration of theory and practice. The case method is a teaching strategy in which students must apply their knowledge to solve real‐life situations. They have to analyze the case described and propose the best possible solution. Although the case may be written, the use of new information and communication technologies can develop the case plan in ways that would achieve greater realism and widen the possibilities for discussion. This paper describes our experience in implementing the case method to teach food safety in the Chair of Hygiene. At first this methodology was used to improve the teaching of good practices in food preparation, later practical work was implemented where small groups of students designed and carried out the microbiological analysis of suspected food. This practical work was presented online as a multimedia activity; students were given face‐to‐face and on‐line tutoring. Evaluation was based both on students’ performance and on a survey they had to answer. More than 92% of students regarded the methodology used for the understanding of the unit as sound. Professors collaboration on providing guidance and multimedia presentation were also positively assessed. The bringing together of face‐to‐face and virtual tasks and small‐group discussion of cases under professors guidance contributed to making good use of the positive aspects of this methodology in order to improve the understanding of problems which do not always have a single answer. 相似文献

Two experiments tested the effects of food deprivation on discounting in pigeons. An adjusting-amount procedure was used to estimate the subjective value of food at delays ranging from 1 to 24 s. Experiment 1 compared pigeons’ discounting of delayed food reinforcers at 75 %–80 % and 90 %–95 % of free-feeding weight. Experiment 2 compared discounting under 1- and 23-h food deprivation. In both experiments at both deprivation levels, discounting was well described by the hyperboloid discounting function. No systematic effect of level of deprivation on degree of discounting was observed in either experiment. This finding is consistent with the view that pigeons’ choices are controlled by the relative, rather than the absolute, value of reinforcers. 相似文献

Word-based byte-oriented compression has succeeded on large natural language text databases, by providing competitive compression ratios, fast random access, and direct sequential searching. We show that by just rearranging the target symbols of the compressed text into a tree-shaped structure, and using negligible additional space, we obtain a new implicitly indexed representation of the compressed text, where search times are drastically improved. The occurrences of a word can be listed directly, without any text scanning, and in general any inverted-index-like capability, such as efficient phrase searches, can be emulated without storing any inverted list information. We experimentally show that our proposal performs not only much more efficiently than sequential searches over compressed text, but also than explicit inverted indexes and other types of indexes, when using little extra space. Our representation is especially successful when searching for single words and short phrases. 相似文献
