The Effectiveness of the National Wildlife Federation’s Schoolyard Habitat Program: Fourth-grade Students’ Standardized Science Test Scores and Science Grades
The purpose of this study was to determine if participation in the National Wildlife Federation’s (NWF) Schoolyard Habitat Program (SYHP) had an effect on the science standardized test scores or science grades of fourth-grade primary school students in Houston, TX. To conduct the study, five pairs of Houston elementary schools were selected as either treatment or control schools. The treatment group included a total of 148 fourth-grade students whose teachers reported using the NWF’s SYHP. The control group consisted of a total of 248 fourth-grade students whose teachers used a traditional science curriculum. To measure academic achievement, scores on a standardized science test and science grades were compared between the treatment and control students. Results from this study indicated Caucasian students scored higher than minority students on the Stanford standardized science exam. Significant differences existed in the Stanford standardized science exam scores between male and female students for the treatment group only. Overall, the results from this study also showed that the SYHP was equally as effective at science instruction as the traditional curriculum within the Houston Independent School District (HISD) after teachers gained familiarity with using the habitat for instruction.
