In a study to measure, compare, and evaluate differential effects of three methods of adult religious education, three experimental groups spent 320 minutes in four discussion meetings with a trained leader and an observer, the latter recording the group Interaction Process Analysis Profile (IPA). The treatment of group I (nine persons) was conducted during a weekend in residence at a campsite. Group II (12 persons) experienced a concentrated, but not residential, weekend program in their local church. Group III (11 persons) met four consecutive Sunday nights at their church. There was a 12-person control group. A knowledge achievement instrument of 20 multiple-choice items and a Likert-type attitude scale were administered as a pretest, a posttest, and a 90-day followup test to all four groups. Results indicated that none of the four discussion meetings were sufficient to effect significant knowledge gain or attitude change. Both weekend programs were superior to the week-by-week treatment in affecting, in subjects, the desire to increase, and within three months actually increase, the percentage of personal or family income given to the church. A Bales IPA profile for adult volunteer religious education groups was derived from this study for reference in future studies. (author/aj)
