The report describes the process of developing and conducting two series of workshops on 'Onshore Impact of Outer Continental Shelf Oil and Gas Development'. The purpose of this report is to evaluate the workshops from the standpoint of their objectives, content, teaching methods, workshop materials, faculty, and logistical arrangements. Fifteen 2.5 day workshops were held between May 1977 and March 1979, attracting over 800 local, state and federal officials, oil industry representatives, and environmentalists from six different coastal regions. Evaluations by the participants and the faculty suggest that the workshops were very successful. The report identifies reasons for this: (1) early assessment of the information needs of the participants; (2) clear objectives for each session of the workshop; (3) effective use of participatory teaching methods; (4) informative workshop materials and hand-outs; (5) skilled and qualified workshop faculty; (6) professional management of workshop logistical arrangements; and (7) responsiveness to participants' evaluations.
