For the twenty-seventh year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the National AECT Convention in Chicago, Illinois. The Proceedings of AECT's Convention are published in two volumes. Volume 1 contains papers dealing primarily with research and development topics. (Individual papers contain references, figures, and tables.) [For Volume 2, see ED499962.]

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a fast pace and affecting academia and professional practice in many ways. Paradigms such as just-in-time learning, constructivism, student-centered learning and collaborative approaches have emerged and are being supported by technological advancements such as simulations, virtual reality and multi-agents systems. These developments have created both opportunities and areas of serious concerns. This conference aimed to cover both technological as well as pedagogical issues related to these developments. The IADIS CELDA 2012 Conference received 98 submissions from more than 24 countries. Out of the papers submitted, 29 were accepted as full papers. In addition to the presentation of full papers, short papers and reflection papers, the conference also includes a keynote presentation from internationally distinguished researchers. Individual papers contain figures, tables, and references.

This paper argues that new technologies, which play significant roles in the process of communication, may solve some problems, but they also tend to create new ones. A discussion of the various problems encountered in Nigeria, where an appreciable penetration of portable video cameras and recorders has given the public more access to, and choice of, media software, is used as an example of the complexities that a new technology may introduce into a system. The effects on the potential audience of the introduction of the more expensive color television rather than continued use of black and white is also discussed. It is pointed out that the broadcast system in Nigeria, as in the Third World generally, is inextricably involved with politics, and that media in Third World countries, including Asia and Africa, are almost always in the direct or indirect service of the government of the day. Such service, it is noted, results in a high percentage of broadcast time being devoted to educational material, and political broadcasts receiving priority over other programs. The broadcasting systems in Asia and South and Central America are briefly described and compared with the systems in Africa, especially in terms of government involvement and control. The political factors operating in the creation of an alternative station in Nigeria are also described. An overview of the world-wide penetration of radio, television, and video recorders in both developed and Third World countries is then provided, and a concluding statement sums up the current situation in Nigeria.

The results of a seminar in which representatives from Australia, New Zealand, and eight Asian countries discussed interdisciplinary research in education are presented. Types of interdisciplinary research were identified, and the conditions necessary for its development were examined. The recent impetus toward interdisciplinary research has emanated from concerns about economic and national development, social justice, the implications for national unity of linguistic and ethnic diversity, and a representation in schools of continuing cultural and social traditions. In some countries there are limitations of knowledge on the part of educational researchers. For example, researchers need to know more about computer and communications technologies. Cooperation and communication among the disciplines and support from the community must be encouraged. Guidelines for the advancement of interdisciplinary educational research are discussed. The annexes, which make up over two-thirds of the report, contain a list of participants and the papers from the individual countries. (RM)
