"In order to help reduce the gap between industrialized countries and those in the emerging economy, UNESCO has decided to adopt an Open Access Policy for its publications by making use of a new dimension of knowledge sharing - Open Access. Open Access means free access to scientific information and unrestricted use of electronic data for everyone. With Open Access, expensive prices and copyrights will no longer be obstacles to the dissemination of knowledge. Everyone is free to add information, modify contents, translate texts into other languages, and disseminate an entire electronic publication."

"... Reclaiming pedagogy as a form of educated and militant hope begins with the crucial recognition that education is not solely about job training and the production of ethically challenged entrepreneurial subjects and that artistic production does not only have to serve market interests, but are also about matters of civic engagement and literacy, critical thinking, and the capacity for democratic agency, action, and change. It is also inextricably connected to the related issues of power, inclusion, and social responsibility.[2] If young people, artists, and other cultural workers are to develop a deep respect for others, a keen sense of the common good, as well as an informed notion of community engagement, pedagogy must be viewed as a cultural, political, and moral force that provides the knowledge, values, and social relations to make such democratic practices possible. In this instance, pedagogy needs to be rigorous, self-reflective, and committed not to the dead zone of instrumental rationality but to the practice of freedom and liberation for the most vulnerable and oppressed, to a critical sensibility capable of advancing the parameters of knowledge, addressing crucial social issues, and connecting private troubles into public issues. Any viable notion of critical pedagogy must overcome the image of education as purely instrumental, as dead zones of the imagination, and sites of oppressive discipline and imposed conformity. ..."

"La evaluación se entiende por parte de muchos profesionales de dos maneras: por un lado, como una estrategia para poder tomar datos sobre el proceso de aprendizaje y así poder regularlo, solucionando las dificultades a medida que ocurren para que todo el alumnado pueda tener éxito contando con los apoyos que sean necesarios; básicamente, en esta interpretación evaluar es obtener datos para comprender y tomar decisiones sobre el proceso de aprendizaje y enseñanza. En la segunda interpretación, más clásica y también la que impone la normativa, evaluar es la vía para medir el aparente nivel de éxito del alumnado y, así, poder calificarlo, aunque aquí se entiende calificar no simplemente como el proceso por el cual se transmite al propio aprendiz y su familia cuál ha sido el resultado en relación con de una o más pruebas sino también como una estrategia de clasificación social del alumnado. Es decir, en el primer caso el objetivo de la evaluación es apoyar el aprendizaje y en el segundo caso el objetivo es clasificar al aprendiz. En estos años, desde los 70 hasta hoy, hemos visto avances en ambos sentidos. En la evaluación para la clasificación se han sofisticado los instrumentos además de que se ha ampliado la capacidad de clasificación para contar hoy con rankings no solo de individuos sino también de entidades mayores como los centros, las regiones o los países. Es más, buena parte de la política educativa se hace buscando la mejora de los resultados en estas clasificaciones, del mismo modo que buena parte de nuestros políticos blanden este tipo de evaluación como argumento de cambio, pues los docentes y los centros reaccionan con frecuencia ante estas evaluaciones acomodando su manera de funcionar al diseño de las pruebas de tal forma que, efectivamente, se obtengan mejores resultados.

"The development of a European sustainability competence framework is one of the policy actions set out in the European Green Deal as a catalyst to promote learning on environmental sustainability in the European Union. GreenComp identifies a set of sustainability competences to feed into education programmes to help learners develop knowledge, skills and attitudes that promote ways to think, plan and act with empathy, responsibility, and care for our planet and for public health. This work began with a literature review and drew on several consultations with experts and stakeholders working in the field of sustainability education and lifelong learning. The results presented in this report form a framework for learning for environmental sustainability that can be applied in any learning context. The report shares working definitions of sustainability and learning for environmental sustainability that forms the basis for the framework to build consensus and bridge the gap between experts and other stakeholders. GreenComp comprises four interrelated competence areas: 'embodying sustainability values', 'embracing complexity in sustainability', 'envisioning sustainable futures' and 'acting for sustainability'. Each area comprises three competences that are interlinked and equally important. GreenComp is designed to be a non-prescriptive reference for learning schemes fostering sustainability as a competence."

"This article analyzes teacher strikes in Argentina during 2006-2012. It stands out how teacher strikes prevail over claims from other unions, and are shown to be relevant events for education policy just for some provinces and only for public schools. We found that none of the policy measures implemented over the last decade has proven to be effective in reducing conflict. Analyzing a dataset on labour unrest, this study builds an index of teacher labour conflict to better understand the evolution of teacher strikes over time and under the various provincial governments that integrate the Argentinian federal education system. The article shows no correlation between teacher labour unrest and the growth of private enrolment. However, we note that despite the lack of statistical correlation, teacher strikes should not be ruled out as an explanatory variable of the increase in private education in Argentina."

Este post plantea un problema ya conocido en la educación: los estudiantes tienen necesidades individuales pero el sistema educativo institucional ofrece un solo camino para que todos aprendan sin considerar propuestas educativas innovativas como la de inteligencias múltiples. Ser inteligente no debe ser considerado solo un resultado del QI.

"This is a program for stretching the audio. It is suitable only for extreme sound stretching of the audio (like 50x) and for applying special effects by "spectral smoothing" the sounds. It can transform any sound/music to a texture. The program is Open-Source and it's released under the version 2 of the General Public License. You can download the source code for Linux or the Windows binaries. Please note that this is suitable only for extreme time stretching (e.g. if have a melody of 3 minutes and you want to listen it in 3 hours). If you want "less extreme" time stretching, you can use a program which contains the SoundTouch library. Features It produces high quality extreme sound stretching. While most sound stretching software sounds bad when trying to stretch the sounds a lot, this one is optimized for extreme sound stretching. So, the stretch amount is unlimited. You can play the stretched sound in real-time (including the possibility to "freeze" the sound) or you can render the whole sound or a part of it to audio files It has many post-processing effects, like: filters, pitch/frequency shifters Support for WAV, OGG VORBIS files and MP3 files It is a Free Software "

"The Chinese government blocked 17.5 million would-be plane passengers from buying tickets last year as a punishment for offences including the failure to pay fines, it emerged. Some 5.5 million people were also barred from travelling by train under a controversial "social credit" system which the ruling Communist Party claims will improve public behaviour. The penalties are part of efforts by president Xi Jinping's government to use data-processing and other technology to tighten control on society."

Magnifica iniciativa abierta a la participación de cualquier persona para crear vídeos de 3 minutos de difusión de las Ciencias de la Tierra. Hay una sección específica donde se invita a participar a centros de E. Primaria y de E. Secundaria "ON THE ROCKS is the first geological video contest for everybody. You should participate with a creative, informal video, where you explain your research, passions or new ideas regarding the Earth, in only 180 seconds. We are looking for passionate contributions by utilizing for example animations, stop-motions, cartoons, time-lapse, interviews, music, poems, dance to demonstrate for a wider public of non-specialists. It should focus on the wonders, dangers and surprises of an adventurous, geological journey, which could take place indoor, outdoor, in a lab, in the mountains, at sea or in the outer space. The potential contributors should therefore be from the scientific community, but could also be passionate and professional multimedia storytellers."

"... Soil is the bedrock of civilization (Perlin 1991, Ponting 1993). Biofuels are not sustainable or renewable. Why would we destroy our topsoil, increase global warming, deplete and pollute groundwater, destroy fisheries, and use more energy than what's gained to make ethanol? Why would we do this to our children and grandchildren? Perhaps it's a combination of pork barrel politics, an uninformed public, short-sighted greedy agribusiness corporations, jobs for the Midwest, politicians getting too large a percent of their campaign money from agribusiness (Lavelle 2007), elected leaders without science degrees, and desperation to provide liquid transportation fuels (Bucknell 1981, Hirsch 2005). ..."
