"CONTEXT/BACKGROUND OF PROJECTIn the last years we have realized in ours schools that the number of students studying experimental sciences was decreasing year after year.Students did not choose scientific options up to the point that biology could not be taught in 4th eso (secondary) during the school year 2006-2007 (in Spain) due to the lack of registered students. Concerned about the problem, the Department of Experimental Sciences began to analyze the possible causes and we soon realized it was a global phenomenon. The same problem was taking place both in Spain and in Europe. The usual teaching of Physics and Chemistry does not take it into account and focuses on the quantitative and operational aspects and ignores some aspects of science which, according to the research in didactics, could contribute to increase the interest towards those subjects as a more qualitative, experimental, more contextualised treatment, showing its contributions to solve human problems and needs.It is in this last sentence where we find the leitmotiv of our project.OBJECTIVESAs a general objective we want to achieve that students, under equal conditions, show more interest in the study of STEM as a result of methodological changes. This project will reach both students with good academic results and students with special educational needs or students at risk of dropping out of school.Secondary Objectives:-The project aims that women feel attracted by STEM subjects as an opportunity, as any other, to get a foothold in society.-Increasing the qualitative character of the STEMs offered in partners schools in order to attract students' interest in science, whatever their academic level. This project also aims to reduce school dropout by making science more contextualized, more practical so that any student may feel attracted to them. -Contextualizing at least one didactic unit for each branch of science worked to bring them closer to students's day-to-day life so that they are attracted to science.NUMBER AND PROFILE OF PARTICIPANTSThe project will reach a minimum of 600 students (50 in mobilities) aged between 15-19 from low and upper secondary students and about 60 teachers including STEM teachers and other teachers (from other subjects). A minimum of 600 families will also be reached (50 in mobilities) in addition to companies, universities and science museums.DESCRIPTION OF ACTIVITIESWe aim to give the five mobilities a scientific congress format with all the details and paraphernalia surrounding a real scientific congress, in order to make the students feel and experience as if they were real scientists. The congresses are the core line of the project, around which a number of activities, products and events are generated before, during and after the congress.METHODOLOGYBefore congresses each school must prepare a practice related to the branch of science that the next Congress will deal with. Teachers to direct that practice will preferably use and take advantage of what the science curriculum in their country offers. In this way it is ensured that these practices are integrated into the syllabus of the school's science subject.On the other hand, the Congresses have allowed us to establish a clear and homogeneous structure of the visits. As we have said before, we intend to give a ""professional"" format, therefore there will be a keynote lecture led by a scientist of some significance in the host country, an exhibition of science communications, workshops where students will carry out the practices, a visit to the school and a presentation of the science curriculum in each country, a training visit to a university / museum and a company related to the congress branch of science, an informal training visit to the school's surroundings and, lastly, a closing ceremony.RESULTS- We will carry out 3 surveys to students and families involved in the project/country to find out their interest in STEM. To observe the interest of the target groups.- Publication of a digital book showing: new laboratory practices, the importance of women in Science, changes made in STEM/country curricula (more experimental, less theoretical, content adapted to students with special educational needs, inclusive and helping to alleviate early school leaving).- Scientific papers and posters presented by the different partners at each congress- Students from the different partner countries will participate in the Experience Fair organized by the University of Valencia showing their experiments.IMPACT/POTENCIAL BENEFITSDigital publishing of all project's products will allow to prolong in time the use of practices and teaching units. Likewise, the fact that they are easily accessible will allow many teachers and, therefore, many students to take advantage of those practices.Finally, we would like this project to wake up in some of the participating students (boys and girls) the wish to pursue science studies and become scientists."
