The first CTW project to use this team approach wasSesame Street, the educational television series created for in-home viewing by preschoolers. Today, the scope of CTW's efforts has widened dramatically to include other media (home video, print, computer software), other learning environments (schools, community organizations, afterschool child-care settings), and other national cultures. This article introduces this issue ofETR&D, which has been authored entirely by CTW researchers, producers, and executives. It describes CTW's approach to research and development, and sets out in broad terms the opportunities and constraints imposed by the environments in which the various projects and productions function. the Association for Educational Communications and Technology, 1990 Educational Technology Research and Development Kluwer Academic Publishers 38/4(1990-12-01), 7-16 1042-1629 38:4<7 1990 38 11423 https://doi.org/10.1007/BF02314640 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF02314640 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Mielke Keith Research at the Children's Television Workshop, USA aut NATIONALLICENCE 773 0- Educational Technology Research and Development Kluwer Academic Publishers 38/4(1990-12-01), 7-16 1042-1629 38:4<7 1990 38 11423 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
