This report presents a formative evaluation of the first year's program of Trailwoods Environmental Science School, a magnet elementary school in the Kansas City School District in Missouri. The school serves students in grades kindergarten through grade 5 and began operation in the fall of 1990. The report focuses on the implementation of the program; achievement scores; and the perceptions of students, parents, and school staff toward the program. Site and classroom visits together with documentation of student participation in theme related field trips provided evidence of the implementation of the magnet theme (environmental science) as well as infusion of the theme across the curriculum. A summary of test scores appears in table form along with clarifying information. Parent and student perceptions of the program were positive while the teacher's response to questionnaires was mixed. Parent, student, and teacher responses are portrayed in tables 10-12. Conclusions and specific recommendations based on the data gathered are contained at the end of this report. Recommendations include a continuation of staff training opportunities; improvement with communication and team building between administration, support staff, and faculty; formulation of a discipline plan; establishment of a cohesive planning team with the principal and extended day program staff; and additional opportunities for computer inservice.
