Significant life experience research suggests that the presence of role models, time outdoors, and nature-related media foster pro-environmental behavior, but most research is qualitative. Based on a random sample of middle school students in North Carolina, USA, we found limited positive associations between presence of a role model and time outdoors with behavior and a negative association between watching nature television and environmental knowledge. The strongest predictors of environmental knowledge and behavior were student/teacher ratio and county income levels, respectively. We also found that Native Americans engaged in environmental behaviors more than Caucasians, and that African American and Hispanic students had lower levels of environmental knowledge. Accordingly, life experiences appear less important than promoting small class sizes and addressing challenges associated with lower incomes in schools.  相似文献

The prereading and reading performance of a group of 370 predominantly Hispanic, bilingual public school children was followed for six years. The aim of the study was to compare the factorial make-up and predictive validity of tests used in the current research with findings from a previous study. The early study had followed the children from the end of their kindergarten year until the end of second grade. For purposes of the present study a 13-test predictor battery was administered to the children at the beginning of their first-grade year. This battery included a number of measures used in the early study, among them a 5-test Screening Index developed in the course of that study. Records were obtained of the follow-up children’s 2nd, 3rd, 4th, 5th, and 6th grade reading test scores. Factor analysis of the pool of 13 predictor tests showed a two-cluster battery structure. These clusters closely resembled two of the four factors defined in the early study. As used with the group of bilingual children, the Screening Index misclassified many of the failing readers, as well as others who went ahead to read at grade level. The Screening Index quite accurately identified, across grades, children who eventually read well. A number of predictor tests administered at beginning of first grade continued to show significant correlations with reading at all grade levels. The consistent contribution of the predictor tests with reading points to their continuing usefulness as a point of departure for assessing children’s readiness to read. The investigation was conducted by the staff of the de Hirsch-Robinson Reading Clinic, Department of Pediatric Psychiatry, Columbia-Presbyterian Medical Center, and the New York State Psychiatric Institute. The work has been supported by generous grants from a number of private donors, among them The Beinecke Foundation, The Morgan Family Fund, The Lita Annenberg-Hazen Charitable Trust, Mr. Seymour Milstein of the Milstein Family Foundation, and Mrs. William Carey.  相似文献
