Comprendiendo el potencial y los desafíos del Big Data en las escuelas y la educación

In recent years, the world has experienced a huge revolution centered around the gathering and application of big data in various fields. This has affected many aspects of our daily life, including government, manufacturing, commerce, health, communication, entertainment, and many more. So far, education has benefited only a little from the big data revolution. In this article, we review the potential of big data in the context of education systems. Such data may include log files drawn from online learning environments, messages on online discussion forums, answers to open-ended questions, grades on various tasks, demographic and administrative information, speech, handwritten notes, illustrations, gestures and movements, neurophysiologic signals, eye movements, and many more. Analyzing this data, it is possible to calculate a wide range of measurements of the learning process and to support various educational stakeholders with informed decision-making. We offer a framework for better understanding of how big data can be used in education. The framework comprises several elements that need to be addressed in this context: defining the data; formulating data-collecting and storage apparatuses; data analysis and the application of analysis products. We further review some key opportunities and some important challenges of using big data in educationEn los últimos años, el mundo ha experimentado una gran revolución centrada en la recopilación y aplicación de big data en varios campos. Esto ha afectado muchos aspectos de nuestra vida diaria, incluidos el gobierno, la manufactura, el comercio, la salud, la comunicación, el entretenimiento y muchos más. Hasta ahora, la educación se ha beneficiado muy poco de la revolución del big data. En este artículo revisamos el potencial de los macrodatos en el contexto de los sistemas educativos. Dichos datos pueden incluir archivos de registro extraídos de entornos de aprendizaje en línea, mensajes en foros de discusión en línea, respuestas a preguntas abiertas, calificaciones en diversas tareas, información demográfica y administrativa, discurso, notas escritas a mano, ilustraciones, gestos y movimientos, señales neurofisiológicas, movimientos oculares y muchos más. Analizando estos datos es posible calcular una amplia gama de mediciones del proceso de aprendizaje y apoyar a diversos interesados educativos con una toma de decisiones informada. Ofrecemos un marco para una mejor comprensión de cómo se puede utilizar el big data en la educación. El marco comprende varios elementos que deben abordarse en este contexto: definición de los datos; formulación de aparatos de recolección y almacenamiento de datos; análisis de datos y aplicación de productos de análisis. Además, revisamos algunas oportunidades clave y algunos desafíos importantes del uso de big data en la educació

Wargame Business: Wargames in Military and Corporate Settings

In recent decades, corporations have turned to wargaming techniques to assess strategic environments and evaluate potential scenarios. The rich history of wargaming and its evolution as a tool for predicting success make it a useful corporate instrument. The lessons learned in business and military games can inform each other to create more-effective gaming outcomes

La relación docente-estudiante en el aula de computación uno a uno

The student-teacher relationship is an important component of both students' and teachers' development. Today, technology-rich learning environments offer opportunities that might change these relationships. This paper presents findings from six studies of teacher-student relationships in the one-to-one computing classroom (and another study that refers to distance teaching). Taken together, those studies—that were carried out in Israel between 2014–2016 using both qualitative and quantitative methodologies, with a combined N=238 teachers—highlight various improvements in student-teacher relationships. Overall, it is argued that one-to-one computing programs drive some important changes in teaching/learning strategies, and that these changes affect student-teacher relationships positively.La relación entre docente y estudiante es un componente importante tanto para el desarrollo de uno como del otro. Los ambientes de aprendizaje actuales, ricos en tecnología, ofrecen oportunidades que podrían cambiar dichas relaciones. El presente trabajo presenta conclusiones de seis estudios de relaciones docente-estudiante en aulas de computación uno a uno (y otro estudio que refiere a la docencia a distancia). Juntos, ambos estudios —llevados a cabo en Israel, entre 2014 y 2016, con metodologías tanto cualitativas como cuantitativas, con una muestra combinada de 238 docentes— resaltan mejoras varias en las relaciones docente-estudiante. En general, se mantiene que los programas de computación uno a uno generan cambios importantes en las estrategias de enseñanza y de aprendizaje, y que dichos cambios afectan las relaciones docente-estudiante de manera positiva

The Gendered Image of Sun Bu’er in Yuan Hagiographies

This research examines the gendered image of the Song dynasty (960-1279) Daoist matriarch Sun Bu’er (1119-1182) based on four hagiographies dedicated to her in four different anthologies from the Yuan dynasty (1271-1368). Building on Sun’s representation in these hagiographies, previous scholarship argued that Sun Bu’er’s Daoist identity is more significant than her gender identity. However, a close study of these hagiographic narratives reveals that as the only female disciple among the Seven Perfected Sun Bu’er was chronicled differently than the six male disciples, with emphasis on her gender. This is evident in the Daoist designation given to her by the Quanzhen founder Wang Chongyang (1113-1170). It is also evident within the hagiographic narratives, where we can detect many themes highlighting Sun Bu’er‘s gender, rather than her Daoist identity. This examination of the hagiographic treatment of Sun Bu’er can further our understanding of how gender played a role in the construction of sainthood, as well as provide a more nuanced understanding of the often idealized relationship between women and the Daoist tradition

Late Pleistocene human genome suggests a local origin for the first farmers of central Anatolia

Anatolia was home to some of the earliest farming communities. It has been long debated whether a migration of farming groups introduced agriculture to central Anatolia. Here, we report the first genome-wide data from a 15,000-year-old Anatolian hunter-gatherer and from seven Anatolian and Levantine early farmers. We find high genetic continuity (~80–90%) between the hunter-gatherers and early farmers of Anatolia and detect two distinct incoming ancestries: an early Iranian/Caucasus related one and a later one linked to the ancient Levant. Finally, we observe a genetic link between southern Europe and the Near East predating 15,000 years ago. Our results suggest a limited role of human migration in the emergence of agriculture in central Anatolia
