Primeras creaciones en el lenguaje infantil. El caso de las metáforas     

Eduardo Martí 《Infancia y Aprendizaje》2013,36(43):3-12

Resumen

La mayoría de los autores reconoce que el niño crea múltiples términos y expresiones cuando empieza a hablar. Estas creaciones (muchas veces erróneas desde nuestro punto de vista), revelan el empleo de diferentes reglas lingüísticas.

Uno de los motivos que conducen al niño pequeño a crear nuevos términos es el metafórico: designar un objeto con un término que normalmente se aplica a otro objeto, similar al primero. Podríamos entonces pensar que el niño, de dos a seis años, es capaz de emplear y comprender el lenguaje figurado, y particularmente las metáforas. Esta hipótesis es criticada a la luz de una serie de hechos experimentales relativos al desarrollo cognitivo del niño.  相似文献   

Some practical approaches to a course on paraconsistent logic for engineers     

Germano Lambert-Torres  Carlos Henrique Valerio de Moraes  Maurilio Pereira Coutinho  Helga Gonzaga Martins  Luiz Eduardo Borges da Silva 《European Journal of Engineering Education》2017,42(6):1296-1308

This paper describes a non-classical logic course primarily indicated for graduate students in electrical engineering and energy engineering. The content of this course is based on the vision that it is not enough for a student to indefinitely accumulate knowledge; it is necessary to explore all the occasions to update, deepen, and enrich that knowledge, adapting it to a complex world. Therefore, this course is not tied to theoretical formalities and tries at each moment to provide a practical view of the non-classical logic. In the real world, the inconsistencies are important and cannot be ignored because contradictory information brings relevant facts, sometimes modifying the entire result of the analysis. As consequence, the non-classical logics, such as annotated paraconsistent logic – APL, are efficiently framed in the approach of complex situations of the real world. In APL, the concepts of unknown, partial, ambiguous, and inconsistent knowledge are referred not to trivialise any system in analysis. This course presents theoretical and applicable aspects of APL, which are successfully used in decision-making structures. The course is divided into modules: Basic, 2vAPL, 3vAPL, 4vAPL, and Final Project.  相似文献   

From body to culture: the need for a developmental psychology view. A commentary on the article Learning beyond the body by Juan-Ignacio Pozo / Del cuerpo a la cultura: la necesidad de una mirada desde la psicología del desarrollo. Un comentario sobre el artículo Aprender más allá del cuerpo de Juan-Ignacio Pozo     

Eduardo Martí 《Infancia y Aprendizaje》2017,40(4):661-675

The necessity of adopting a developmental perspective to understand the role that the body and action play in children’s representations is argued in proposals made by Pozo in his article Learning beyond the body: from embodied representations to explicitation mediated by external representations. The transformative power of action is valued from this developmental perspective, while at the same time revealing the close link between action, cognition and communication. Similarly, the explicitation and implicitation processes are considered to be recurrent phases that occur in any stage of development, applied to embodied knowledge as well as to more elaborate and explicit knowledge.  相似文献   

The construction of a double-entry table: a study of primary and secondary school students’ difficulties     

Eduardo Marti  Merce Garcia-Mila  Fernando Gabucio  Katerina Konstantinidou 《European Journal of Psychology of Education - EJPE》2011,26(2):215-234

Tables are a presentation format that is commonly used to organize information, and they are widely present in many scenarios of our students’ everyday activities; however, there is a scarcity of studies devoted to their analysis. Some of these studies point out that the organization of data into a double-entry table presents difficulties for primary and secondary school students. The present study analyzes the following: (1) the level of competency of primary and secondary school students in constructing a double-entry table from a set of data and (2) the main difficulties encountered by these students during the task. Our findings showed that the percentage of middle-school students who succeeded in contructing a conventional table was relatively low, and the number did not significantly increase over four school years. A set of difficulties is identified and discussed in terms of cognitive and graphical processes.  相似文献   

The direct and indirect effect of motivation for learning on students' approaches to learning through the perceptions of workload and task complexity     

Eva Kyndt  Filip Dochy  Katrien Struyven  Eduardo Cascallar 《高等教育研究与发展》2011,30(2):135-150

The present study investigates the direct and indirect influence of motivation for learning, as understood by the self‐determination theory, on students' approaches to learning. Concerning the direct influence of motivation, results show that autonomous motivation is positively related to a deep approach to learning and negatively to a surface approach. Motivation also has an indirect effect on students' approaches to learning through the perceptions of workload and task complexity, in particular through the perception of a lack of information. The greater the extent to which students are autonomously motivated, the less they perceive that they have a lack of information and the less they are inclined to adopt a surface approach to learning.  相似文献   

Multicultural education, pragmatism, and the goals of science teaching   总被引：1，自引：1，他引：0  

Charbel Niño El-Hani  Eduardo Fleury Mortimer 《Cultural Studies of Science Education》2007,2(3):657-702

In this paper, we offer an intermediate position in the multiculturalism/universalism debate, drawing upon Cobern and Loving’s epistemological pluralism, pragmatist philosophies, Southerland’s defense of instructional multicultural science education, and the conceptual profile model. An important element in this position is the proposal that understanding is the proper goal of science education. Our commitment to this proposal is explained in terms of a defense of an ethics of coexistence for dealing with cultural differences, according to which social argumentative processes—including those in science education—should be marked by dialogue and confrontation of arguments in the search of possible solutions, and an effort to (co-)live with differences if a negotiated solution is not reached. To understand the discourses at stake is, in our view, a key requirement for the coexistence of arguments and discourses, and the science classroom is the privileged space for promoting an understanding of the scientific discourse in particular. We argue for “inclusion” of students’ culturally grounded ideas in science education, but in a sense that avoids curricular multicultural science education, and, thus, any attempt to broaden the definition of “science” so that ideas from other ways of knowing might be simply treated as science contents. Science teachers should always take in due account the diversity of students’ worldviews, giving them room in argumentative processes in science classrooms, but should never lose from sight the necessity of stimulating students to understand scientific ideas. This view is grounded on a distinction between the goals of science education and the nature of science instruction, and demands a discussion about how learning is to take place in culturally sensitive science education, and about communicative approaches that might be more productive in science classrooms organized as we propose here. We employ the conceptual profile model to address both issues. We expect this paper can contribute to the elaboration of an instructional multicultural science education approach that eliminates the forced choice between the goals of promoting students’ understanding of scientific ideas and of empowering students through education.

Evaluation of a new equation for estimating low-density lipoprotein cholesterol through the comparison with various recommended methods     

Eduardo Martínez-Morillo  María García-García  María Angeles Luengo Concha  Luis Rello Varas 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(1)

IntroductionThe accurate estimation of low-density lipoprotein cholesterol (LDL) is crucial for management of patients at risk of cardiovascular events due to dyslipidemia. The LDL is typically calculated using the Friedewald equation and/or direct homogeneous assays. However, both methods have their own limitations, so other equations have been proposed, including a new equation developed by Sampson. The aim of this study was to evaluate Sampson equation by comparing with the Friedewald and Martin-Hopkins equations, and with a direct LDL method.Materials and methodsResults of standard lipid profile (total cholesterol (CHOL), high-density lipoprotein cholesterol (HDL) and triglycerides (TG)) were obtained from two anonymized data sets collected at two laboratories, using assays from different manufacturers (Beckman Coulter and Roche Diagnostics). The second data set also included LDL results from a direct assay (Roche Diagnostics). Passing-Bablok and Bland-Altman analysis for method comparison was performed.ResultsA total of 64,345 and 37,783 results for CHOL, HDL and TG were used, including 3116 results from the direct LDL assay. The Sampson and Friedewald equations provided similar LDL results (difference ≤ 0.06 mmol/L, on average) at TG ≤ 2.0 mmol/L. At TG between 2.0 and 4.5 mmol/L, the Sampson-calculated LDL showed a constant bias (- 0.18 mmol/L) when compared with the Martin-Hopkins equation. Similarly, at TG between 4.5 and 9.0 mmol/L, the Sampson equation showed a negative bias when compared with the direct assay, which was proportional (- 16%) to the LDL concentration.ConclusionsThe Sampson equation may represent a cost-efficient alternative for calculating LDL in clinical laboratories.  相似文献
