This qualitative study was conducted in a large north Texas school district. The subjects were four elementary teachers who had previously attended a summer aerospace education workshop. The researcher observed in each classroom during science instruction and other areas where aerospace concepts might be taught to determine material usage, practices, and perceptions associated with teaching aerospace. The teachers' lesson planbooks, textbooks, and supplementary materials were also examined by the researcher. Interviews were conducted with each teacher's principal and the district science coordinator to determine their effects on the practices and perceptions of the subjects.
