L@S: Fourth Annual ACM Conference on Learning at Scale April 20 – 21, 2017 @ Massachusetts Institute of Technology organized with the Association for Computing Machinery (www.acm.org). In 2007, Plan Ceibal became the first nationwide ubiquitous educational computer program in the world based on the 1:1 model. It is one of the most important programs implemented by Uruguay’s Government to minimize digital divide and is based upon three pillars: equity, learning and technology. As of 2007, Plan Ceibal has covered public schools, providing every student and teacher in kindergarten, primary and middle school with a laptop or tablet and internet access in the school, as well as a comprehensive set of educational software platforms. Plan Ceibal reached 85% of the students in Uruguay (100% of public education 1 to 9 grades students) reducing significantly the digital divide between the “have” and the “have-nots”. After the massive deployment of devices, platforms and connectivity, as well as educational resources, now the focus is particularly on teachers training, development of new pedagogies as well as a new culture for understanding teaching and learning (i.e. new pedagogies for deep learning). This presentation summarize the "computational thinking" and the "maker culture" promoted by this public policy in Uruguay. http://www.fundacionceibal.edu.uy/en/page/about-us by @cristobalcobo
