A study was designed to determine the relative effectiveness of a series of landscape meetings and a supplemental illustrated landscape circular in teaching landscape design concepts to interested groups. The cooperation of county agents was secured. Five counties were selected as experimental; five, as control. Teaching objectives were formulated and a circular selected. The testing instrument, developed by the investigator, consisted of four pictorial questions from which the respondents were forced to judge between good and bad landscaping. The remaining 36 questions were multiple-choice. Respondents in the experimental and control groups took this and a standardized spatial relations test. A landscape rating scale was completed at the end of the four meeting series. No significant difference was found between the experimental and control groups. (NL)
