Nature centers have been important in the implementation of non-formal environmental education in Western countries. However, few studies on nature centers have been done in Taiwan. This study begins to fill a gap in the research relating to nature centers in Taiwan. The major purposes of this study are (1) to determine how the Meifong Farm of National Taiwan University planned and implemented their two-day environmental education program, (2) to explore the program participants' motivation, expectation, and satisfaction, and (3) to evaluate the service quality of the Meifong Farm utilizing "importance-performance analysis". Both quantitative and qualitative approaches were used to collect the data. Document analyses, participant observation, and semi-structured interviews were conducted to determine the mission, development strategies, and program implementation of the Meifong Farm. A total of 546 valid questionnaires were collected to assess the participants' motivation, expectation, and satisfaction. The resulted indicated that the most important motivation of the participants is "the service of environmental interpretation." Ninety-four percent of participants supported that the Meifong Farm should focus on environmental education for future development. The importance-performance analysis indicated that the strengths of the farm were "service of environmental interpretation" and "natural landscapes" and the weaknesses were "sanitation" and "quality of housing and accommodation services." According to the research results, it was suggested that environmental education should be the first priority for the future development of the Meifong Farm. It was also suggested that environmental interpreter employment and training programs should be improved in order to provide environmental education programs with high quality.
