Adult leaders from 14 counties, divided into matched participating (57) and control (54) groups, were surveyed to evaluate whether Cooperative Extension Service programs on land use planning in Arkansas resulted in increased knowledge and more favorable attitudes toward such planning. Participants filled out attitudinal questionnaires before attending an educational meeting. After two months, questionnaires including attitudinal, factual, and demographic questions were sent to both groups. Results did not substantiate a previous evaluation showing no knowledge increase but greater favorability. In this study, no significant meeting effects were found. Though the participating group was more favorable toward county government control of land use planning, less favorable toward Federal responsibility, and less likely to think no government level should be involved than the control group, these differences were shown to have existed even before the meeting. Only one factual item was significantly different--meeting participants were more likely to know zoning could protect farm land from urban development. Although this and the earlier evaluation found interest about land use planning high, county leaders preferred data on current land use policies and actual planning processes. Also, newsletters or some other medium might be more effective than public meetings. (RS)
