520    Coincidental increases in online instruction at 
       institutions of higher education and in online social 
       networking generally in the U.S. have created 
       opportunities for research into how digital interpersonal 
       connectivity affects online learning. This study examined 
       interactive webcasts, or webcasts plus chat, that were 
       part of an online undergraduate course covering Internet 
       knowledge and skills at a large public university. 
       Symbolic interactionism served as the theoretical 
       framework for explicating interactive webcasts as useful 
       online learning environments by exploring the complex 
       processes that instructional staff employed to manage 
       their actions and interactions as moderators in the 
       webcasts and chats 
520    A constructivist grounded theory approach guided the 
       collection and analysis of empirical data in the form of 
       webcast media and transcripts, chat logs, students' 
       reflective writing, and semi-structured, intensive 
       interviews with instructional staff. From the study 
       emerged theoretical categories in three tiers related to a
       generalized moderator process called minding the verge: 
       moderators minded the verge in three conditions of 
       interaction -- converging, attending, and diverging; in 
       three loci of interaction -- webcasts, chats, and webcasts
       +chat; and through six actions of moderating -- bonding, 
       orientating, guiding, tending, validating, and branching 
520    The results of this study provide moderators for the 
       course with insights into their actions in the interactive
       webcasts and with concepts moderators can use to explore 
       how to manage interactive webcasts more effectively. 
       Beyond effecting substantive changes to interactive 
       webcasts for the course, the study may guide others who 
       wish to pursue further studies of webcasts+chat as they 
       occur in the course or elsewhere, or of other mixed-media 
       environments, or who wish to adopt mixed-media 
       environments for instruction. Other potential areas for 
       research that emerged from this study include the 
       affective states of participants in the webcasts+chat and 
       the use of affective devices, such as emoticons and 
       abbreviations, for showing affective states; the effect 
       that format has on the efficacy of webcasts+chat used for 
       computer-mediated instruction; and the processes students 
       employ to manage actions and interactions in the webcasts 
       and chats
