¿Se pueden enseñar contenidos procedimentales en las clases de ciencias?
Authors: Pro Bueno Antonio de 
Published: June 2021

The paper we present raises a central question: Can scientific processes be taught in science classes? To be able to answer this initial question some previous issues must first be considered:Are the learning of processes new in the teaching of Science?If both researchers and teachers do not conceptualize these ideas in the same way, what then should we understand by the learning of processes?How are these instructional contents being investigated at present?Beginning with the identification of research areas in this field, we attempt to answer further questions:- Are there different levels of complexity in a single process?- How could we use these ideas in the planning of instructional activities?To analyse some of these considerations we have used the contents Tabulated Data and Control of Variables.
Influencia de la formulación del enunciado y del control didáctico sobre la actividad intelectual de los alumnos en la resolución de problemas
Authors: Langlois F. , Gréa J. , Viard J. 
Published: June 2021

Using as reference the scientist instead of the expert for analysing the pupil's behaviour in problem solving, we proposed to students (17 years old) closed and open problems. The great diversity of the students' productions and their analysis in the theoretical framework of didactical contract, oblige us to build two analysis grids: one of the students' activities and the other one for the finalities which we attribute to those activities. We show how ranging the strategy of resolution depends on the text of the problem.
La utilización del vídeo para la enseñanza de conceptos básicos (calor y temperatura)
Authors: Insausti M. J. , Beltrán M. T. , Crespo M. S. , García R. 
Published: June 2021

The goal of one of the inquiries implemented in the ANTEC Project (Aplicación de las Nuevas Tecnologías a la Enseñanza de las Ciencias) was to analyze the use of videotapes as a means to teach Sciences. In this paper we present the use of vídeotapes related to Heat and Temperature Units, in classrooms with students who were 16 years old. We expected to modify their concepts about these subjects. The results suggest the improvement of students' concepts and vocabulary, although it was not the same with the application of scientific knowledge to everyday events.
Un análisis de las concepciones acerca de la naturaleza del conocimiento científico de los profesores portugueses de la enseñanza secundaria
Authors: Praia Joao , Cachapuz Antonio F. 
Published: June 2021

Secondary science teachers play an important role in forming the image of science that is held by their pupils. However, research suggests that quite often science teachers' conceptions of the nature of scientific knowledge are little better that of their students. In Portugal, there are no research studies which may help to characterise science teacher's epistemological views in order to design appropriate training courses. This study aims (i) to diagnose what conceptions (empiristirationalistic) are held by Portuguese secondary science teachers concerning the relationship between theory and observation and also about the called scientific method (ii) to ana.lyse the relationship between such conceptions, and the variables subject matter taught and professional experience. Basic data was generated from responses to a questionnaire (multiple choice questions) given by a representative sample of 464 science teachers. The results showed the predominance of empirist views (nearly 2/3 of the sample) about the two aspects investigated. Ernpirist views seem to be independent of the teaching subject and professional experience. The need for adequate training courses is discussed and stiggestions concerning their design are proposed.
Curso de ingreso en química a la universidad: un espacio de revisión y aprendizaje conceptual
Authors: Raviolo A. , Andrade Gamboa J. 
Published: June 2021

In this article we report a didactic experience, based on a contructivist approach we carried forward in a chemistry classroom in the University Admittance Course, with the aim to promote conceptual revision and learning. Essentially two basic conceptual cores (discontinue nature of matter and conservations of matter properties) were taken into account. We started from previous ideas and pupils' difficulties. Several methodological strategies to overcome them were developed.
Difficultés dans l'apprentissage du mesurage
Authors: Larcher C. , Séré M.G. , Journeaux R. 
Published: June 2021

This paper presents the difficulties encountered by students of first University year, when carrying out measurements in order to answer a question concerning the isochronism of oscillations o a simple pendulum. It is based on a case study which concerns students who followed a course about measurement eforhand. The global strategies of these students are described. Then the difficulties encountered are analysed. We distinguish two categories: firstly, the difficulties stepping from relationships between a theoretical approach of modelised objects and an experimental approach of given objects; secondly the difficulties coming from the conzeptualisation of differences between the measured values and the reference value. Eventually, elements of the response built by the students are analysed, particularly by assessing the reinvestment of the notions of statistics studied beforehand.
Elaboración y utilización de audiovisuales en la enseñanza de la química
Authors: Llitjós Viza Anna , Estopà Miró C. , Miró Clària A. 
Published: June 2021

This article shows the process of elaboration, and the optimal conditions for their use, of audiovisuals as backup material for chemistry classes. We distinguish between producing videos for internal and external use. We stress the importance of the technical quality and the content of videos for external use, and the importance of the teamwork involved in their preparation too. We also examine the role of the scientist at each stage of the process of producing audiovisuals. Finally, we presenta series of videos that we have made, and suggest possible lines of research for future projects in this field.

Quelques reflexions sur le concept d'entropie issues d'un enseignement de thermodynamique
Authors: Brosseau C. , Viard J. 
Published: June 2021

The authors establish the existence of a gap between physics' students conceptions concerning the notion of entropy and Clausius's, Boltzmann's, constructors of this concept. They analyze some basic features at the origin of these conceptions and some characteristics of the common sense interpretation of entropy. They conclude by some didactical propositions.

La masa no se crea ni se destruye ¿Estáis seguros?
Authors: Oñorbe de Torre A. , Sánchez Jiménez J. M. 
Published: June 2021

From the very outset of the study of chemistry, the concepts of mass, physical and chemical transformations of matter and the law of conservation are fundamental. However, in reality, the learning of these concepts that pupils believe they understand is not very secure. When they try to apply their ideas to simple questions they make mistakes and the reasoning they use does not correspond to the explanations or definitions that they are able to repeat.
Historia de la matemática: Integración cultural de las matemáticas, génesis de los conceptos y orientación de su enseñanza
Authors: González Urbaneja Pedro Miguel 
Published: June 2021

This report seeks to claim a didactic function for the History of Mathematics, justifying the fact that a complete and profound understanding of the fundamental concepts of any science requires the knowledge of its history. The excessive logical -deductive nature of present Mathematics has given rise to an excessive dogmatism in its teaching, together with an imposition of exactness and strictness as the fundamental, almost exclusive, values of Mathematics, thus influencing the students' negative response. We believe that these deficiencies can be put back to right by means of the teaching of the History of Mathematics, so as to enrich the teachings culturally. We suggest this subject be integrated inter -disciplinarily into the curriculum, and considered a source of inspiration, permanent self training, and orientation for all educacional activity.

Interacciones ciencia/técnica/sociedad : un instrumento de cambio actitudinal
Authors: Solbes Jordi , Vilches Amparo 
Published: June 2021

In the present work we show how one of the facts that may help to create a more favourable attitude of the student towards science is the inclusion of the Science/Technique/Natural and social environment relations in the text books: and this approach is not sufficiently explicit in the text books we have analysed.

This work has two purposes:a) To find out the persistence grade of sorne preconceptions which pupils of second year of B.U.P. have about fluid's statics..b) To check whether the teaching method used is the adequate one for our pupils.Before the fluid's statics study was started we gave them five questions; two monts later we gave them the same questions again.The results show out that an important number of pupils strongly maintained the same wrong ideas they had before this subjet was studied.
Semejanzas y diferencias entre las concepciones infantiles y la evolución histórica de las ciencias : el ejemplo del concepto de fuerza y especialmente del de fuerza de gravedad
Authors: Casadellà Reig Josep , Sanmartí Puig Neus 
Published: June 2021

This research refers to the evolution of learning the concept of gravity. The previous ideas of the students, aged 12-13, were analysed to be taken into account prior to the methodology design. An imaginary character defending the students' views was introduce to raise polemics. Among other results, we want to outline that the theory of «ímpetus» eventually come out of the students and was coherently formulated.

Una investigación del aprendizaje del cálculo aritmético
Authors: Lamarca París J. Mª 
Published: June 2021

The aim of this article is that of showing a specific approach in the Didactics of Arithmetic Calculus, and the results that have been achieved using it with about 300 students in the first year of SUP: we also want to show certain criteria which could allow us to improve our method. Such criteria are based both on the realization of the didactIc method itself and on the assumption of certain cognitive factors which have great influence on the learnin& of Arithmetic Calculus. Throughout the developing of our approach in the Didactics 5f Arithmetic Calculus we have emphasized the sections devoted to the teaching of calculus, error enalysis and calculus problem solving (according to Polya).

Applying a bibliometric analysis to the Spanish bibliographic production devoted to new teaching methods in the experimental sciences, published between 1975-1983, trends in teaching innovation are presented. The ocurrence points in which the innovation is taking place, the teaching levels and the topics in which new methods are being used are shown. A comparison with the French bibliographic production at the same time reveals the different ways in which teaching innovation in experimenta: sciences is going in both countries.
Influencia del conocimiento del resultado numérico en la resolución de problemas
Authors: Perales Palacios F. Javier , Cervantes Madrid A. 
Published: June 2021

In this paper an experimental study about a specific aspect of physics problem solving is carried out; namaless, the previous knowledge of their solution. Two groups of students attending the teachers' Training College of Granada were selected. Both groups were at random divided into two subgroups; one group knew the problem solutions before the experiment but the other one did not. The influence which the introduced variable exerts on the planning and solution of the problems, when the pupils are tested, has been statistically analyzed.

Les principes d’équité et d’utilité dans l’allocation des ressources limitées en
situation de pandémie
Authors: Saint-Arnaud Jocelyne , Mullins Gary , Ringuette Louise 
Published: June 2021

La pandémie de COVID-19 remet à l’honneur la question éthique de l’allocation des
ressources limitées, en termes d’accès à des soins intensifs et à des respirateurs. Se pose
la question éthique suivante : sur quels principes éthiques se baser pour effectuer le
triage des patients qui auront accès aux ressources quand elles sont insuffisantes pour
répondre aux besoins de tous? Pour en débattre, deux références historiques de triage sont
d’abord présentées ; l’une s’appuie sur un principe égalitaire de réponse aux besoins
individuels, l’autre sur un principe d’utilité sociale. Après avoir défini les conditions
d’équité en tant qu’égalité procédurale et réponse adéquate aux besoins, deux types de
protocoles sont étudiés en mettant l’accent sur les critères d’équité et d’utilité qu’ils
préconisent. Les types de protocoles sont ensuite comparés en présentant leurs forces et
leurs limites dans la réponse qu’ils apportent aux besoins populationnels et individuels.
Notre analyse met en évidence la difficile conciliation entre les objectifs populationnels
et les objectifs cliniques en situation de pandémie, tout en montrant qu’un protocole qui
utilise comme outil le Sequential Organ Failure Assessment (SOFA) facilite cette
conciliation.
Médicalisation et autonomie des femmes affectées par le syndrome des ovaires polykystiques
Authors: Doudenkova Victoria 
Published: June 2021

Le syndrome des ovaires polykystiques (SOPK) est un trouble endocrinien répandu qui affecte environ 10% des femmes en âge de procréer. Bien qu’il soit principalement connu pour ses effets sur la fertilité, le SOPK est considéré comme un facteur de risque pouvant mener au diabète de type 2. Il est également associé à des conditions comme les cancers hormono-dépendants, les troubles psychiatriques ou encore les maladies cardio-vasculaires. La volonté de prévenir les conditions associées pourrait pousser à une plus grande médicalisation des femmes atteintes par le SOPK, notamment par d’éventuels dépistages. Cet article examine les facteurs potentiels pouvant contribuer à la médicalisation de ces femmes et la manière dont leur autonomie pourrait être affectée par ce phénomène. Entre autres, l’article met en évidence comment la médicalisation façonne des représentations collectives et individuelles par rapport aux notions de santé, de maladie et de traitement. Dans une perspective relationnelle de l’autonomie, il attire l’attention sur l’importance de reconnaitre comment la médicalisation influence ces représentations et l’impact potentiel que cela pourrait avoir sur les femmes. Encourager la démédicalisation du SOPK par une approche visant à soutenir la santé pousse à interroger ces représentations et fait partie des pistes de solution permettant de favoriser l’autonomie des femmes affectées par le SOPK. Il devient alors possible non seulement de contrôler la maladie, mais aussi de soutenir la santé, voire de faire les deux selon la situation individuelle.
Lifting Health Professionals’ Morale During the COVID-19 Pandemic: Moderating Emotions to Support Ethical Decisions
Authors: Blasco Pablo González , de Benedetto Maria Auxiliadora C. , Levites Marcelo R. , Moreto Graziela 
Published: June 2021

The current COVID-19 pandemic creates a difficult and unprecedented time. With each passing day, the care of the health team itself is essential; and not only physical care, but also for mental health. The authors describe their experience in disseminating recommendations through short videos to help professionals maintain an objective view of the reality they are experiencing. Thus, knowing how to tabulate daily the evolution of the patients that each professional has been entrusted to care for – the hospitalized, the deaths and, very importantly, the discharge of the recovered – provides a sense of reality. Cinema, an educational resource used in medical education, which is also included in these videos, helps to clarify the recommendations made above and to maintain emotional balance. The authors conclude that providing a realistic view of the situation that the team is experiencing in this crisis and highlighting the positive facts and achievements could be a valuable means of help from medical educators behind the scenes.
“Agents of Description”. Animals, Affect, and Care in Thalia Field’s Experimental Animals: A Reality Fiction (2016)
Authors: Lambert Shannon 
Published: June 2021

In this article, I explore questions of laboratory animal agency in dialogue with Thalia Field’s literary text “Experimental Animals: A Reality Fiction” (2016). Using the framework of “care” (understood, following María Puig de la Bellacasa 2017, as a multi-dimensional concept comprising affect, ethics, and practice), I consider how Field’s synaesthetic descriptions of animal suffering create an affective response in readers, alerting them to a shared carnal vulnerability. Indeed, rather than anthropomorphizing animals through narration or focalization, Field “stays with the body” to consider how animals call to us not as experimental objects, but as ethical subjects, how they become – in other words – agents of the description (Stewart 2016). To develop this idea, I introduce the “practiced” dimension of care. More specifically, I explore how Field uses narrative strategies like first-person narration and second-person address, “bridge characters” (James 2019), and juxtaposition to morally structure the text and encourage “transspecies alliances” between readers and represented animals. I argue that such devices direct and train affect, allowing us to better appreciate how conceptions of nonhuman animal agency are always contextualized within particular sets of social, cultural, historical, and disciplinary frames and practices.
