EXCOVE and using videos in knowledge elicitation

Expert commentary of videotaped expertise (EXCOVE) is an approach to knowle dge elicitation (KE) where expert performance is videotaped and then these videotapes are used to assist the e:licitation of knowledge from these and other experts. It was initially formulated to assist in the understanding o f the complex area of psychotherapy. Psychodrama was chosen as the form of psychotherapy to trial EXCOVE. Seven hours of videotaped data anti 28 h of commentary data were collected and analysed. Evaluation of EXCOVE in the li ght of these analyses indicated that its unique combination of using video, multiple experts, and interviewing focused on specific events can be usefu l in KE endeavours. However, there are high overheads involved in the recor ding, transcription, coding and management of video and commentary data. (C ) 2001 Academic Press.
