This study assessed the effectiveness of FireWorks, an educational trunk about wildland fire, in increasing student understanding, enabling students to apply classroom learning in a field setting, and improving the learning environment. Students who were in classrooms using the FireWorks educational trunk demonstrated more knowledge in both classroom and field-based tests than did students in comparison groups. Students using FireWorks were more interested and engaged in learning than students in comparison classrooms. FireWorks students rated their classrooms as being more orderly and better organized, and rated their teachers as more innovative, creative, and interested in student input than did students in comparison groups. Teachers of FireWorks were less likely to be interrupted to reprimand students than were teachers of comparison classrooms.
