Application of Felton and Kuhn's framework for analysing argumentative skills during a role play.

Argumentation has become important for understanding how people reason and make decisions about socioscientific issues. One challenge of science education is promoting argumentation practices in science classrooms and improving preservice teachers' argumentation skills, which is essential to reinforce their future teaching practices. In this paper, we analyse the preservice primary teachers’ discursive processes when participating in a role play about nuclear power to identify their main limitations in argumentation practice. 28 preservice primary teachers from the University of Málaga participated in this study during the 2018/19 academic year. For data analysis, an adaptation of Felton and Kuhn’s framework was applied. The results show that role play as a teaching strategy has favoured the use of counterarguments and countercritics, although, at the same time, there is also a lack of use of dialogic resources to question the arguments of others.Universidad de Málaga.

Pre-service teachers’ ideas about obtaining electricity in nuclear power stations in a role play context

This study examined whether participation in a role play on the socio-scientific issue of the use of nuclear power had an impact on pre-service primary teachers’ ideas regarding the process of obtaining electricity in a nuclear power station. Before and after the role play, 78 pre-service primary teachers were asked to describe this process to analyze the ideas they displayed about the stages involved in it. The results showed, overall, an increased presence of more scientifically informed ideas in some of these stages following the role play, although a number of nonscientifically informed ideas persisted, for example, regarding the way in which heat is obtained or the final transformation of energy into electricity. These results support the potential value of role play for developing more scientifically informed ideas, although some modifications of the role play are recommended for further development of them.This study was supported by the European Social Fund and Spain’s National Research Agency through a researcher training contract (PRE2018-083328) as part of the Excellence in R+D project “Developing the competences of secondary and university students in relation to everyday problems through the scientific practices of argumentation, inquiry and modelling” (EDU2017-82197-P), by the Spanish National Plan R+D+i Project, entitled “Citizens with critical thinking: A challenge for teachers in science education” (PID2019-105765GA-I00), and the support for open publishing by the University of Malaga

Los feminismos y la currícula universitaria: su impacto en la dimensión político-pedagógica y epistémica

En el desarrollo de este capítulo, correspondiente al segundo encuentro del Seminario de Transversalización de la perspectiva de género, me propongo abordar las implicancias político-pedagógicas de transversalizar la perspectiva de género tanto en el diseño curricular universitario como en las políticas de ingreso sostenidas por las diferentes unidades académicas de la Universidad Nacional de La Plata. En una primera parte pondré el foco en los aportes de las epistemologías críticas feministas, muy especialmente en la crítica que diferentes vertientes del feminismo han realizado sobre la ciencia moderna, así como en la relevancia que tiene este cuestionamiento para volver la mirada sobre las políticas de formación universitaria. En una segunda parte, se retomaré los aportes de la educación popular para pensar cuáles son las maneras posibles de transitar hacia una pedagogía feminista que ponga en tensión nuestros modos de enseñar y aprender en la Universidad. En este sentido, parece relevante esta revisión crítica de la Universidad como institución formadora y, en particular, de las políticas de ingreso dado que están dirigidas a jóvenes que han egresado recientemente de la escuela secundaria y en poco tiempo más se convertirán en nuestres estudiantes universitaries. Las preguntas que se proponen a continuación pueden ser el comienzo de un proceso que busca transversalizar la perspectiva de género en el diseño curricular, en las políticas de ingreso y en las prácticas como docentes y como investigadores. Ellas son: ¿cuáles son los aportes de las epistemologías críticas feministas? ¿De qué modos permiten cuestionar los saberes de referencia del currículum universitario? ¿Por qué se vuelve urgente y necesario transitar hacia una pedagogía feminista? ¿Qué relación podemos establecer entre pedagogía feminista y derecho a la educación?Facultad de Humanidades y Ciencias de la Educació

“Education Network” a new way to teach Chemistry

The complexity of chemistry has implications for the teaching of chemistry. That chemistry is a very complex subject. The majority of the students at University think that chemistry is a difficult discipline and they have difficulty in understanding the concepts. Moreover, students' interest in chemistry decreases the first year at university. The reason for this decrease might be that the contents of chemistry laboratory classes are boring, out of date and lacking of dynamism that students experience through visual media tools. For these reasons, new programs and methodologies should be developed. Those are based on making chemistry relevant through problem solving and collaborative learning hold promise for reforming chemistry education. It is about an education according to circumstances, which is adapted to context and virtual behaviour of people. It's time to CRUSH boredom by transforming your classroom into an Escape Room adventure. School-based escape games are a great teaching tool. The students while playing, learn. The most important point is that they won’t realize they’re doing both at the same time. In this work, an educational gamification experience based on the escape room concept was developed. The first (Do It Yourself) DIY Escape Room was built the year before at Mechanical Engineer Degree started, that took more than three weeks of work. It was presented to other professors to the same subject at different degrees. That DIY Escape Room was modified and adapted to each group. Each professor changed the clues, problems and so on in order to orientate the topic as much as possible to their students.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

El periodismo local reinventa estrategias. Decálogo para los desafíos en tiempos de inteligencia artificial [Local journalism reinvents strategies. Decalogue for the challenges in times of artificial intelligence]

Local and hyperlocal journalism is experiencing times of great change. It is reinventing and reinforcing strategies to survive in a scenario where news deserts have increased, many local media have disappeared and many news projects are finding it difficult to keep up with the pace of production and innovation imposed by the digital ecosystem. The digital transition has led to the appearance of many native media, especially due to the reduction of procedures and the ease of creating a platform on the web, but few had solid projects. Now, with the massive arrival of Artificial Intelligence (AI), many of these media outlets that have resisted the onslaught of adaptation, are convinced that they must review their strategies and look back at their audiences, who have not always been known in depth or understood their needs and demands, despite the multiple metrics that exist to monitor media consumption

The role-playing game as a teaching strategy on environmental awareness development. A Design-Based Research.

Este trabajo muestra el desarrollo de experiencias de juegos de rol sobre la producción de energía nuclear a lo largo de tres cursos académicos, cuya metodología se ha ido modificando teniendo en cuenta los resultados obtenidos en cada una de ellas mediante una investigación basada en el diseño. Los sucesivos cambios metodológicos han mostrado mejoras en cuanto a los resultados obtenidos en cada experiencia respecto a las anteriores, concluyéndose que el juego de rol se muestra como una estrategia que favorece tanto el aprendizaje de conceptos científicos básicos como el tratamiento de aspectos concernientes a la conciencia ambiental, fomentando la práctica de habilidades argumentativas y poniendo en juego opiniones, creencias, actitudes y posiciones de muy diversa índole.This work shows the development of role-playing game experiences on nuclear energy production over three academic years and whose methodology has been modified based on the results obtained in each of them, through a design-based research. The methodological changes have shown improvements in terms of the results obtained in each experience with respect to the previous ones, assuming the role-playing game as a strategy that favours the learning of basic scientific concepts, such as the treatment of aspects concerning environmental awareness, encouraging the practice of argumentative skills and implies opinions, beliefs, attitudes and positions of a very diverse nature

Does opening a milk bank in a neonatal unit change infant feeding practices? A before and after study

<p>Abstract</p> <p>Background</p> <p>Donor human milk banks are much more than simple centers for collection, storage, processing, and distribution of donor human milk, as they cover other aspects and represent a real opportunity to promote and support breastfeeding. The aim of our study is to assess the impact that opening a human milk bank has had on the proportion of infants receiving exclusive breast milk at discharge and other aspects related to feeding children with birth weight < or = 1500 g or < 32 weeks gestation admitted to the neonatal unit.</p> <p>Methods</p> <p>The study included babies of < or = 1500 g or < 32 weeks gestation. Fifty infants born from February to July in 2006, before the opening of the human milk bank, and 54 born from February to July in 2008, after its opening, met inclusive criteria. We collected data about days of hospital stay, hours of life when feeding was started, hours of life when full enteral feeding was attained, the type of milk received during admission, and the type of feeding on discharge.</p> <p>Results</p> <p>Children born in 2008 commenced feeding 16 hours earlier than those born in 2006 (p = 0.00). The proportion of infants receiving exclusive breast milk at discharge was 54% in 2006 and 56% in 2008 (p = 0.87). The number of days they received their mother's own milk during the first 28 days of life was 24.2 days in 2006, compared to 23.7 days in 2008 (p = 0.70). In 2006, 60% of infants received infant formula at least once in the first 28 days of life, compared to 37% in 2008 (p = 0.01).</p> <p>Conclusions</p> <p>The opening of a donor human milk bank in a neonatal unit did not reduce the proportion of infants exclusively fed with breast milk at discharge, but did reduce the proportion of infants that received infant formula during the first four weeks of life. Also, having donor human milk available enables commencement of enteral feeding earlier.</p
