[en] Two experiences of teacher distance training using new information and communication technologies are described. These experiences were developed in 2000-2002 to promote the public acceptance of nuclear energy, including efforts from the Chilean Nuclear Energy Commission (CCHEN, http://www.cchen.cl) , the Metropolitan University of Sciences of Education (UMCE, http://www.umce.cl) , the Center for Improvement, Experimentation and Pedagogical Research (CPEIP, http://cpeip.mineduc.cl) and the National University Network (REUNA, http://www.reuna.cl). The experiences described consist of improving courses for teachers working at the basic and intermediate levels in the Chilean educational system. Both courses focused on methods and resources that support constructive teaching and meaningful learning of both basic concepts and peaceful applications of nuclear energy, in line with contemporary theories and practice in the teaching of sciences, technology and society. In the first of these experiences, developed in 2000 and entitled ^Teacher's Workshop: Nuclear Energy in Education. A Didactic Approach^, the course received support from the International Atomic Energy Agency (IAEA). Five interactive video conference sessions were implemented to cover a wide area of the country, thanks to the Virtual University Network at REUNA (http://www.uvirtual.cl). Another component of the instructional system was a web site to help with matters like the delivery of learning materials and communications among the participants. In the second experience, developed in 2001-2002 and entitled ^Educational Debate: Man, Society and Nuclear Energy^, the authors received support and funding from the InterAmerican Virtual Center of Cooperation for Teacher Formation (CIDI-OEA). The participants in the distance course were from several countries, including Chile, Argentina, Colombia, Brazil and the Dominican Republic. Instructional resources included a virtual learning environment via Internet and the video conference network of the Virtual University Project at REUNA. Conditions in Latin America are good for establishing collaborative strategies for advancing educational proposals of mutual interest relative to the common problem of public acceptance of peaceful applications of nuclear energy, in the same way as in other areas of nuclear science and technology at the international level (cw)
