Competencia Científica y Resolución de Problemas de Física
2020
Resumen Impulsar y desarrollar la competencia científica entre los estudiantes que cursan materias como la Física, es un objetivo contemplado actualmente de forma explícita en la mayoría de los currículos escolares y es compartido por muchos expertos en Didáctica de las Ciencias Experimentales. Sin embargo, cuando se trata este tema con el profesorado de ciencias, suele hacerse ignorando los contenidos concretos de la materia a enseñar, con lo cual, los profesores difícilmente pueden trasladar a sus clases aquello que les ha sido expuesto en términos demasiado generales o abstractos. En nuestra opinión, si realmente se quiere impulsar y desarrollar la competencia científica, ello ha de hace…
Impact of “Relation with learning” on scientific conceptions and knowledge among gymnasium pupils
2014
International audience; According Balacheff and Clement models, knowledge (K) and conceptions (C) interact mutually. Clement seems to define conceptions as a set of items fueled by values, practices and knowledge while Balacheff defines knowledge as a set of situated conceptions. Moreover, Chevallard and Charlot make the hypotesis that learning requires a factor commonly underestimated: the “relation with learning”.This study surveys the impact of the relation with learning on the evolution of scientific conceptions and knowledge among learners. It intends to test the Charlot and Chevallard hypothesis as well as the Balacheff and Clement models in order to identify a possible interaction be…

Staging and storing data sprint-based research results: a communication design approach
2022
Data sprints are multidisciplinary, time-limited, practice-oriented, and group activities that explore complex issues through data gathering, visualization, and analysis. Data sprints usually conclude with final presentations where participants showcase the research process they followed and the achieved results. Although this activity is now widespread in some research centers, there does not appear to be a data-sprint tailored dissemination format that can support the organization, archive, and online diffusion of results. Starting from the experience of a data sprint on Digital Methods, the paper describes the design process of a digital format which condenses and reinterprets good pract…
Geological and cultural heritage: Dissemination experiences in Tuscany
2019
We report on some recent experiences of scientific dissemination activities on geomaterials carried out by a network of scientific organizations in Tuscany (Italy). The primary message we want to disseminate is that even the most "insignificant" rock (e.g., those constituting the bar or kitchen counter-tops) stores in their interior very useful information beyond the beautiful colors and their aesthetic appearance. These rocks can tell stories of very old geological periods on how they were formed. Their structures, texture and shape, as well as their chemistry and mineralogy provide clues to the reconstruction of geological events. Moreover, the rocks used in urban architecture and monumen…
Science education and the “state of the world”: a programme of activities to enhance teacher’s perception of global problems and possible remedies
2003
A literatura sobre formação de professores de ciências não tem tratado suficientemente a situação do mundo quanto a uma percepção global de seus graves problemas atuais. O presente artigo consiste essencialmente de um programa de atividades a ser desenvolvido com professores em formação e em exercício, que visa favorecer uma reflexão coletiva e conscientização sobre essa problemática. Nesta perspectiva é apontado um conjunto de referências e questões para um debate fundamentado sobre vários dos fatores associados à degradação da vida e sobre possíveis medidas para o enfrentamento da emergência planetária. Investigações preliminares sobre a utilização do programa proposto têm revelado result…
Perceptions of university students about their education in physics in secondary education
2018
Este artículo presenta los resultados de un cuestionario diagnóstico sobre las percepciones hacia la física, por parte de 104 estudiantes, quienes inician su carrera profesional de Licenciatura en Ciencias Naturales y Educación Ambiental, en una universidad colombiana. Este estudio, se centró en las siguientes categorías: experiencias sobre el aprendizaje de la física, metodología del profesor en la clase de física, dificultades de los estudiantes para aprender física y sugerencias para mejorar su enseñanza. Los resultados reflejan la importancia de explorar y generar estrategias, que permitan optimizar las cuatro dimensiones; por ejemplo, en relación al aprendizaje de la física, los partic…
Scientific discovery and its role in sports science
2016
Scientific discovery is about a search for the Truth, for the consistent and predictable in how the universe works. Using a particular method of inquiry, the scientific method, and with acknowledgement of the inherently self-correcting nature of science, scientific inquiry moves forward incrementally to ever closer approximations of the Truth. This paper reviews the history of scientific inquiry, the methodology of the scientific method, including the necessity for hypothesis testing and development of the probability that a particular answer is a closer approximation of the Truth than previous answers have been. It also discusses some of the pitfalls of scientific inquiry, and areas in whi…
Sobre alguns participis actius amb verbs de moviment
2021
L’objectiu d’aquest estudi és analitzar les estructures formades a partir de la combinació d’un participi amb un verb de moviment, en casos com venir plorat de casa. L’interès d’aquestes dades rau en el fet que els participis que descrivim no són actius (plorat, tossit), però adquireixen una lectura activa en combinar-se amb verbs de desplaçament (venir, sortir, arribar). Al llarg de l’article recopilem i descrivim les dades que segueixen aquesta configuració i mirem d’esbossar alguns apunts per a una possible anàlisi formal. D’una banda, seguint la proposta d’Armstrong (2017), defensem que verbs com plorar o tossir permeten la formació d’un participi actiu resultatiu perquè tenen un object…
: " Si tu veux la paix, prépare la guerre " ou " si tu veux la paix, prépare la paix " ?
2012
International audience; A la fin du IVe siècle dans son Traité de l'art militaire (De re militari), le chrétien Végèce a écrit : " qui désire la paix, se prépare donc à la guerre ". Son ouvrage, utilisé comme manuel de moralisation du guerrier par l'Eglise catholique, est encore qualifié au début du XIXe siècle par des stratèges militaires de " Livre d'or " des règles de la guerre. Mais cet adage toujours présent dans l'esprit de nos contemporains a été dénoncé en 1841 par le saint-simonien Barthélemy Prosper Enfantin qui a écrit : " si tu veux la paix, prépare la paix ". Le mouvement pacifiste qui s'est développé depuis les conflits napoléoniens peine à reprendre son souffle à la fin de la…
