The Effect of a Five Day Residential Environmental Education Program on Urban Middle School Students’ Environmental Knowledge David Christopher December 2003 The effect of a five-day residential summer camp on four urban middle school students’ environmental knowledge was investigated. Students were interviewed three times during the week of camp using four general questions about the Chesapeake Bay. The questions were individually scored; the scores were added together to yield a total interview score for each student. The interview scores fluctuated, and no trends in the data could be seen. The results of this study must be considered in light of the threats to their internal and external validity, current environmental literature, and observations made of and by the camp students. Recommendations for program development and further research are recommended.
