This exploratory study of children's use of electronic text systems drew upon site visits, interviews, and data compilations for an overview and synthesis of issues. Systems studied included Green Thumb (videotext, Kentucky); Channel 2000 (videotext, Ohio); KCET (teletext, California); WETA (teletext, Washington, D.C.); QUBE (interactive cable, Ohio); Sesame Place (microcomputers, Pennsylvania); and Capital Children's Museum (microcomputers, Washington). Following the site visits and other data collection, two conceptualizations were undertaken. One, on behavioral issues in children's use of electronic text systems, is grounded in the literature on child development. The other, a features analysis of electronic text systems, specifies differences that may affect children's use of and learning from the systems. This five-chapter study report concludes with questions for future research organized according to the paradigm, "Who learns what from which electronic text system and with what effects on other learning and behavior?" A 30-item reference list is included. (Author/LMM)
