The main purpose of this study was to explore and compare resource-saving behaviors among junior high school students in Tokyo and Taipei. Also, the study utilized the PRECEDE model to explore the influential factors of environmental protection behavior among the students. The sample included two parts: (1) 289 seventh-grade students and their parents at four schools in Tokyo, and (2) 1, 115 seventh-grade students and their parents at ten schools in Taipei. The data were collected in September and October of 1994. As a whole, the students in Taipei displayed higher knowledge and more positive attitude, sensitivity and concern toward environmental protection than the students in Tokyo. The former also performed more environmental protection behavior than the latter except for ?grecycling at home". Howerver, the parents in Tokyo performed more environmental protection behavior and were more concerned about child education than the parents in Taipei. In addition, the total components of the PRECEDE model instrument explained 46.1 percent (Tokyo) and 32.2 percent (Taipei) of the variance in predicting environmental protection behavior. The significant predictors in both two groups were ?gconcern" and ?gpractical confidence".
