AMI en Latinoam茅rica Aproximaci贸n, an谩lisis y propuesta de medici贸n sobre el contexto de la Alfabetizaci贸n Medi谩tica e Informacional en Am茅rica Latina
Esta tesis doctoral desarrolla una metodolog铆a para la evaluaci贸n de la alfabetizaci贸n medi谩tica e informacional (AMI), que se basa en los marcos propuestos por la UNESCO (2011, 2013) y la Comisi贸n Europea (Celot y P茅rez Tornero, 2009), brindando una adaptaci贸n de las recomendaciones dise帽adas por estos dos grandes representantes de la AMI aplicable al contexto espec铆fico de Am茅rica Latina. Tambi茅n hace una revisi贸n de literatura sobre las teor铆as generales relacionadas con la alfabetizaci贸n medi谩tica e informacional, as铆 como de estudios en AMI llevados a cabo en diferentes pa铆ses, principalmente en los once seleccionados para esta investigaci贸n. De esta manera, se plantea un enfoque amplio sobre la AMI que tiene en cuenta diversos autores e instituciones que trabajan en este campo (ACRL, 2000; Ainley et al., 2012; NAP-ICTL, 2012; P茅rez-Tornero, 2007; UNESCO, 2008; Celot y P茅rez-Tornero 2009; Lau y Cort茅s, 2009; Renee Hobbs, 2010; UNESCO, 2011, 2013; Giraldo et al., 2014, entre otros). Teor铆as relacionadas con la edu-comunicaci贸n, la alfabetizaci贸n medi谩tica, estudios de medios, alfabetizaci贸n informacional, alfabetizaci贸n TIC/digital, alfabetizaciones m煤ltiples, etc., han sido comparadas y analizadas. El resultado es la creaci贸n de un marco te贸rico s贸lido tanto sobre la competencia medi谩tica como sobre la evaluaci贸n del contexto AMI. El estudio se basa en un profundo an谩lisis de contenidos que sistematiza variables relacionadas con pol铆ticas p煤blicas, planes de estudios, planes nacionales en TIC, seguridad cibern茅tica y elementos relacionados con la AMI en general (alfabetizaci贸n informacional, alfabetizaci贸n digital, competencia medi谩tica) en los once pa铆ses estudiados. Tambi茅n tiene en cuenta un amplio cuestionario aplicado a una muestra de 44 expertos en AMI provenientes de Argentina, Chile, Colombia, Costa Rica, Ecuador, M茅xico, Panam谩, Per煤, Rep煤blica Dominicana, Uruguay y Venezuela. La investigaci贸n muestra c贸mo los pa铆ses de Am茅rica Latina se est谩n adaptando a la sociedad del conocimiento -a velocidades bastante diferentes- y describe (y se centra en ello) un escenario de r谩pido movimiento en el que se observa la manera en que algunos pa铆ses de la regi贸n comienzan a concentrar sus esfuerzos en acciones que van m谩s all谩 de la fase embrionaria de generaci贸n de oportunidades de acceso a las TIC (infraestructura TI en general, programas 1:1, ciber-centros, construcci贸n de redes, etc.). Tambi茅n muestra c贸mo los pa铆ses del mismo nivel de ingresos (medio-alto) han llevado a cabo diferentes estrategias digitales que, en algunos casos, han conducido a resultados de alto impacto. El resultado de esta investigaci贸n es una propuesta de "脥ndice de preparaci贸n AMI" y un amplio primer mapeo de los factores que favorecen a la AMI en la regi贸n.This thesis develops an assessment methodology on Media and Information Literacy (MIL), which is based on the frameworks proposed by UNESCO (2011, 2013) and the European Commission (Celot & P茅rez Tornero, 2009), adapting the directions given by these two major representatives in the field of MIL to the specific context of Latin America. It also makes a literature review on media and information literacy general theories as well as on MIL studies carried out in different countries, mainly in the eleven selected for this research. A broad approach to MIL is drafted taking into account several authors and institutions working on this field (ACRL, 2000; Ainley et al., 2012; NAP-ICTL, 2012; P茅rez-Tornero, 2007; UNESCO, 2008; Celot & P茅rez-Tornero, 2009; Lau & Cort茅s, 2009; Renee Hobbs, 2010; UNESCO, 2011, 2013; Giraldo et al., 2014, among others). Theories related to edu-communication, media literacy, media studies, information literacy, digital/ICT literacy, multiple literacies, etc. have been compared and analyzed. The result is the creation of a robust theoretical framework both on media competence and on MIL context assessment. The study relies on a deep content analysis that systematizes variables related to public policy, school curriculum, ICT plans, cyber-security, and media and information literacy elements (informational literacy, digital literacy, media competence) in the eleven countries studied. It also takes into account a comprehensive questionnaire with a sample of 44 MIL experts from Argentina, Chile, Colombia, Costa Rica, Ecuador, Mexico, Panama, Peru, Dominican Republic, Uruguay and Venezuela. The research shows how countries in Latin America are adapting to the Knowledge Society -at very different speeds- and describes (and focuses on) a fast-moving scenario where some countries of the region are starting to concentrate their efforts on actions that go beyond the embryonic stage of generating opportunities to access ICT (general IT infrastructure, 1:1 programs, cyber-centers, networks building, etc.). It also shows how countries on the same income level (mid-high) have run very different digital strategies which, in some cases, have led to high impact outcomes. The result of this research is a "MIL Readiness Index" proposal and a rich first mapping of the MIL enabling factors in the region
