Do pause ao play - um novo modelo de aula
Authors: Figueiredo Mairon Neves 
Published: June 2021

Já estamos em 2021 e o problema da pandemia de COVID 19 ainda assombra a educação pública no Brasil (BRASIL, 2020). Por todo o país se percebem severas limitações na implantação de políticas públicas voltadas a inserção do ensino remoto na grade escolar (PAZ, 2020). Quando bem implementado esse modelo de ensino agrega interatividade mesmo a conteúdos complexos e possui diversos potenciais benefícios aos estudantes (FIGUEIREDO, 2020). As vídeos-aulas, quando disponibilizadas aos alunos apresentam um enorme potencial no estimulo ao ensino e a qualidade do aprendizado. As aulas remotas possibilitam que o conteúdo exposto apesar de breve possa ser interativo agregando aos vídeos vantagens únicas.
Neste modelo de ensino os estudantes podem assistir assiduamente as aulas, repetindo e revendo o material até que se busque uma melhor compreensão. Assim, temas de grande complexidade, que presencialmente necessitariam de horas de explicações e interações estudante-professor, podem ser assistidos novamente (ROESLER; CERON; ANDRADE, 2003). Logo o estudo pós-aula, tende a ser melhor aproveitado, visto que as falas podem ser assistidas até que a interpretação atinja o a mensagem proposta em aula.
Os vídeos também possibilitam a que o aluno exerça o poder de pausar e continuar o estudo quando melhor lhe convém. Assim é possível que o estudante assista apenas trechos de uma aula, ou mesmo no horário e nos momentos em que o vídeo proporcione um conteúdo mais necessário.
Outro grande diferencial se refere a possibilidade de aceleração dos vídeos. Trechos longos e com falas espaçadas e lentas podem ter seu tempo de estudo comprimido sem que exista perda na compreensão. Com o tempo os estudantes são capazes de acelerar trechos e otimizar o aprendizado do conteúdo em um tempo hábil bem menor.
Certamente as plataformas que utilizam vídeos aulas como ferramentas de estudos auxiliam na complementação do aprendizado (ALVES, 2011). Do mesmo modo, vale lembrar que desde o ensino fundamental, médio e superior (BRASIL, 2017) a realidade na dinâmica das aulas e o contato aluno-professor são bem diferentes. Entretanto o empasse em estimular a volta as aulas presenciais bate de frente com a necessidade do isolamento social (WHO, 2020), obrigando a adoção dos meios digitais de ensino. Assim é de grande valia analisar e planejar o uso dessas ferramentas de ensino, mesmo durante o período pós-pandêmico, já que seu legado pode vir a trazer grandes avanços ao ensino.
NEUMOTÓRAX ESPONTÁNEO DEBIDO A BULAS SUBPLEURALES. PRESENTACIÓN DE UN CASO
Authors: Maggiolo M Julio , Rubilar O Lilian 
Published: June 2021

El neumotórax se define como la presencia de aire dentro de la cavidad pleural. Puede ser traumático, iatrogénico, espontáneo secundario o primario, dentro de esta última causa la más frecuente son las bulas subpleurales y apicales, en pacientes longilíneos, portadores de enfermedades del tejido conectivo y fumadores.
En neumotórax pequeños el tratamiento debe ser conservador, en cambio en los de mayor cuantía se debe proceder a la instalación de una sonda pleural. Frente a recidivas frecuentes o persistencia del escape aéreo, se debe considerar la pleurodesis o bien practicar la resección de las bulas.
En el presente artículo se reporta a un paciente con síndrome de Elhers Danlos que presenta un neumotórax espontáneo primario debido a bulas subpleurales.

Published: June 2021

ÖZET
Çin’in Wuhan şehrinde, Aralık 2019 tarihinde görülmeye başlayan, SARS-CoV-2 (şiddetli akut solunum sendromu koronavirüsü-2) olarak adlandırılan, yeni tip koronavirüsün şiddetli akut solunum sendromuna neden olduğu belirlenmiş ve acil durum ilan edilmiştir. Yapılan araştırmalarda COVID-19 enfeksiyonu için komorbidetelerin varlığı, obezite, ileri yaş gibi faktörlerin kötü prognozu öngösterdiği belirlenmiştir. COVID-19 ile diyabetin etkileşimli patofizyolojik mekanizmaları nedeniyle, COVID-19 sürecinde diyabetin etkin yönetimi oldukça önem arz etmektedir. Diyabet yönetiminin mevcut zorluklarına, COVID-19 salgının bireylerin yaşamlarına getirdiği yüklerin eklenmesi ile sürecin daha kompleks bir hal aldığı görülmüştür. COVID-19 salgınının yaşattığı kriz ile mücadele edilirken, diyabet bakımını iyileştirmek için de yeni stratejiler, eylem planları, yönergeler geliştirmeli ve bu planlamaların hızlıca uygulamaya dökülmesi gerekmektedir. Pandemi sürecinde diyabetin etkin yönetimi için de multidisipliner ekip yaklaşımı gerektirmektedir ve diyabet hemşirelerine önemli rol ve sorumluluklar düşmektedir. Salgın sürecinde, diyabet hemşirelerinin uygulayacağı bakım; diyabetli bireyin yaşamına getirdiği yüklerin azaltılması ile hedeflenen glisemik değerlerin sürdürülmesine, diyabetin akut komplikasyonların önlenmesine, acil başvurularının azaltılmasına, gereksiz hastane başvurularının önlenmesine, hastaneye yatışların engellenmesine, hastanede kalış süresinin azaltılmasına, komplikasyon oranlarının düşürülmesine, kontrolsüz diyabetin sağlık hizmetlerine getirdiği yükün en aza indirgenmesine, sağlık personelinin bakım yükünün azaltılmasına, diyabetli bireyin yaşam kalitesinin iyileştirilmesine ve en önemlisi COVID-19 risklerinin azaltılmasına katkı sağlayacaktır.
La enseñanza de la ecología. Un objetivo de la educación ambiental
Authors: Fernández Manzanal R. , Casal Jiménez M. 
Published: June 2021

In this article we study the repercussion that studies on ecology may have on environmental education. To do so, we review the student's alternative ideas about concepts and principles of ecology selected for the study of the subject. We stress the idea that outings to the countryside to study a specific ecosystem helps to clarify the interactions between the living things and the environment. Finally, we give the data of a research performed with high school students, supporting the idea that those students who carry out work in the countryside are able to define a larger number of components and relationships. Such training favours the transfer of ecology knowledge, both in the evaluation of an environmental problem and in proposing solutions.
Una nueva fuente de inspiración para la educación científica
Authors: López Rupérez F. 
Published: June 2021

In this paper, physics, epistemology and the teaching and learning of physics are presented as a transdisciplinary system. With such an approach, the fundamental principles of contemporary physics considered in a qualitative form —epistemological principles— are postulated as a source of inspiration for Science Education. In this way, a new trend for fundamental educational research is defined.
Ideas previas y cambio conceptual en astronomía. Un estudio con maestros de primaria sobre el día y la noche, las estaciones y las fases de la Luna
Authors: Camino Néstor 
Published: June 2021

In this paper we present an experience developed with primary teachers which led to the design of a course, from a constructivistic point of view, on those concepts related to Astronomy included in primary curricula (day and night, seasons, moon phases).With the comparison of pre/post diagnoses (written questions and clinical interviews), we discuss the effectiveness of this conceptual change strategy and make some conclusions, particularly on teacher training.
Redes conceptuales: su aplicación como instrumento didáctico en temas de física
Authors: Galagovsky Lydia R. , Ciliberti N. 
Published: June 2021

Concept Nets are the result of the need to acquire an instrument with which to improve the students' cognitive style of learning (Galagovsky 1993a). For the last four years we have been researching about the benefits of its use in different subjects and levels. We now introduce an application in Physics, at High School level, developed during 1991-1992. A new research period 1993-1994 is being pursued.
La matemática escolar como lenguaje. Nuevas perspectivas de investigación y enseñanza
Authors: Rojano Teresa 
Published: June 2021

In this article we have made a collection of the focuses and trends in the research on school mathematics considered as a language, which has characterized the research in the 80s and the beginning of the 90s —in contrast with the 70s decade, when the construction of concepts was thought of as the central objective of studying. We also deal —as a matter inherent to research— with the topic of the possible didactic implications that such focus can entail.
Más allá del positivismo: una interpretación lakatosiana de la enseñanza de las ciencias
Authors: Níaz M. 
Published: June 2021

The history of science shows that positivism was the dominant philosophy from about the end of the 19th century to the middle of the 20th century. The main objective of this article is to present a critique of positivist ideas and show how the new philosophy of science, as represented by Lakatos, has important implications for science education.

In a longitudinal study, carried out with 12-17 year old students, to know learning obstacles and their evolution through schooling years, on the scientific concept of soil, we have found important data of learning problems on these topics, showing the established inefficiency of transmission of scientific knowledge to conceptual change. Lastly, we point out some implications for the teaching and significative learning of these concepts.
Concepciones de los estudiantes sobre una magnitud "olvidada" en la enseñanza de la química: la cantidad de sustancia
Authors: Furió-Mas Carles , Azcona Rafael , Guisasola G. , Mujika E. 
Published: June 2021

The main objective of this paper is the identification of the students' representations about the idea of substance quantity and to see to what extent the establised Chemistry teaching in Secondary schools contributes to giving them a more atomist view of matter. The results obtained in this work confirm that students, upon completing their studies, have practically not changed their `globalise conception of substance quantity, and only half of those that studied chemistry master the necessary activity to be able to understand the mole concept.
Ideas sobre el concepto biológico de población
Authors: Berzal de Pedrazzini M. , Barberà O. 
Published: June 2021

The population concept is one of the foremost in biology, and íts comprehension is essential to grasp the genetical and evolutionary aspects of living beings. Nevertheless, school science hardly takes into account the richness arid complexity of the biological concept of population. We have carried out this study with the intention of finding out students' ideas about the population concept (and other concepts related to it such as the species concept) and putting forward some hypotheses to explain the origins of these ideas.
Los algoritmos para el cálculo de la raíz cuadrada y sus antecedentes en textos escolares antiguos
Authors: Núñez i Espallargas Josep M. , Servat Susagne J. 
Published: June 2021

First of all, there is an analysis of the historical and scientifical motivations that lead to the inclusion of the usual square root algorithm in mathematics in elementary education, as well as of the textbook that introduced them for the first time in Spain. Secondly we take into account two alternative algorithms for the calculation of square roots proposed by modern didactical literature of mathematics teaching, and show that, in both cases, it is possible to find precedents of their utilization in old elementary textbooks.
Le conoscenze in Física all'inizio dei corsi universitari in Italia
Authors: Ianniello M. G. , Mayer Marc , Scalzo F. 
Published: June 2021

The article reports the results of an investigation on Italian university students concerning physics knowledge related to common sense schemes at the beginning of the university courses. The results of the diagnosis were communicated both to the students and to the teachers of the courses. The communication enabled the teachers, in the didactical practice, to pinpoint and discuss with the students the discrepancies between the scientific newtonian scheme and common sense scheme. A posttest, given at the end of the course, gives the indication that this practice is effective in inducing a clonge in the students ideas, notwithstanding the fact that no complete understanding of the scientific viewpoint is leached by the majority of students.

Concepciones previas en el aprendizaje significativo del electromagnetismo
Authors: Colombo de Cudmani L. , Fontdevila P. A. 
Published: June 2021

Difficulties that are present in the basic conceptualizations of electromagnetism are analized. The logic way, followed in physics instruction, which is not necessarily the most adequate to initiate the study of the subject is emphasized. The psychological importance of the previous concepts is also considered. As a consequence the investigation is faced through inquiries, observations, and data accumulation along the teaching experience on the most frequent preconceptions. The statistical work has been carried out with students of secondary level and university college. As a conclusion subsumers are proposed, which appear as the most adequate to the study of electromagnetism courses content structuration.
Conceptos espontáneos sobre colisiones
Authors: Villani Alberto , Pacca Jesuïna Lopes de Almeida 
Published: June 2021

This work shows Physics Graduate students ways of thinking about the phenomenon of collisions and the physical quantities which are conserved in this process. Written questions and interviews about the described problems enabled us to analyse answers with expectations and explanations for the effect of simple and multiple collisions. Spontaneous models which were found, show fundamental aspects also obtained in other researches with high school students, although with different frequencies depending on the level (graduate or secondary) and on the complexity of problems.
¿Cómo flotan los cuerpos que flotan? Concepciones de los estudiantes
Authors: Barral F. M. 
Published: June 2021

A research was carried on pupil's ideas, from Primary School to University, on the flotation of cork, wood and ice on water. Different alternative ideas were found, being the commonest the belief in some bodies floating over the water surface, without any submerged volume. Causes of these alternative conceptions are discussed, and some implications for Science teaching -learning suggested.

El "status" socio-académico de las matemáticas : un punto de referencia singular
Authors: Arana Pérez J. , Escudero Escorza Tomás , Garces Campos R. , Palacian Gil E. 
Published: June 2021

Results of different surveys among students of basic and secondary education show that mathematics are perceived as a subject -matter with special status, as compared with the rest of disciplines; its importance, academic utility, difficulty and boredom are emphasized. This panorama changes a little according to educational levels, kind of studies, courses and so on, but the differenciated socio -academical status persists.
Contra el mito de la neutralidad de la ciencia : el papel de la Historia
Authors: Catalan Fernàndez Albert , Catany Escandell M. 
Published: June 2021

Most of the teachers of Science lack theoretical explicit elements to guide their educational action. So they contribute to transmit the myth of neutrality in the scientific orientation and development, and, in this case, Science can fulfil a ruling and justifying role. Against this proposal, we suggest a conscious assumption of some values in the general context of scientific education and even in the general one of a rational education. We put special emphasis on Science as a basic and necessary reference to individual and social behaviour, but not an exclusive one. We also propose: 1) recovering the utopic sense of Modern Science that took place in its origins, and 2) investigating the environment, its past, present and future as a guide to place the student in a nonalienated from and self-forgetful connexion. And, finally, we declare for reason and against oppresion.
Interpretación errónea del concepto de entropía
Authors: Candel Rosell Agustín , Satoca Valero José , Soler Llopis Juan B. 
Published: June 2021

In this paper, we make a revision of the concepts of molecular order and disorder, meaning that the second principle of Thermodynamics, when it demands the increase of entropy in every natural process which takes place in an isolated system, does not imply necessarily and increase of the purely «spacial» disorder: an isolated system may develop by becoming «spacially» organized, but by becoming «thermically» disorganized (configurational entropy and thermic entropy) in such a way that it verifies the second principle as a whole.
Ideas sobre los gases en alumnos de 10 a 15 años
Authors: Furió-Mas Carles 
Published: June 2021

This paper shows some ideas the students have on specific perceptive aspects of gases, such as their materiality or the volume they take, together with the analysis of their answers to their internal structure. The results found are similar to those obtained from other context. It is confirmed that students maintain an urisioielic vision of the substantiality of gases, thcitigh some features of the particulate theory (accepted at present as for their internal structure) equally appear.

Les petites chouettes de montagne (Chouette de Tengmalm, Aegolius funereus (Linnaeus, 1758) et Chevêchette d’Europe, Glaucidium passerinum (Linnaeus, 1758)) sont représentées en France par quelques centaines à quelques milliers de couples. Elles font l’objet d’une attention particulière au regard de leur rareté et en tant qu’espèces emblématiques des écosystèmes forestiers de montagne, qui sont particulièrement affectés par les changements globaux. Améliorer la connaissance de leur distribution, notamment dans les Alpes du Nord, est une nécessité pour préserver les milieux qui constituent leur habitat préférentiel. Issue d’une collaboration entre l’INRAE, l’Office national des Forêts et la Ligue pour la Protection des Oiseaux, nous présentons une approche par modélisation dans laquelle des données d’occurrence des deux espèces sur la période 2007-2014 ont été reliées à six variables environnementales potentiellement explicatives pour prédire leur répartition. Les résultats montrent que la distribution des deux espèces est principalement liée d’une part à l’altitude, facteur déterminant au plan régional, et d’autre part au type d’occupation du sol, meilleur prédicteur à l’échelle locale, alors que les autres facteurs (topographie, proximité de lisières) sont moins explicatifs. Ces prédictions ont été utiles aux naturalistes de terrain, qui ont pu utiliser ces données pour mieux structurer leurs campagnes d’observations. Il serait désormais intéressant d’étendre la démarche à d’autres zones biogéographiques et d’intégrer à la modélisation des données permettant d’évaluer les effets de la gestion forestière sur ces espèces.
Sailing Yacht Capsizing
Authors: Stephens Olin J. , Kirkman Karl L. , Peterson Robert S. 
Published: June 2021

The 1979 Fastnet focused attention upon yacht capsizes and resulting damage and loss of life.
A classical stability analysis does not clearly reveal some of the characteristics of the modern racing yacht which may exacerbate a capsizing tendency. A review of the mechanism of a single-wave-impact capsize reveals inadequacies in static methods of stability analysis and hints at a connection between recent design trends and an increased frequency of capsize.
The paper traces recent design trends, relates these to capsizing by a description of the dynamic mechanism of breaking wave impact, and outlines the unusual oceanography of the 1979 Fastnet which led to a heightened incidence of capsize.
