This study investigated the effects of workshop and lecture methods on pastoralists' learning in Ilam Province, west of Iran. A quasi-experimental research method and non-equivalent control group design was used. Sixty pastoralists participated in this study. An open-ended questionnaire was used as the instrument of the study and found to have content validity and inter-rater reliability. Findings of the study showed a significant difference between effectiveness of lecture and workshop through pre- and post-tests. In general, the workshop method was proven to be more effective in improving pastoralists' learning with regard to preservation, renovation, and utilization of rangelands due to better decision making about their rangeland management practices. Most importantly, the workshop method also seemed to have established the behavioral mapping of these factors to a greater degree for participants. (Contains 9 tables and 1 figure.)
