The program was evaluated using a collection of surveys, some of which were developed internally and some of which were developed externally.⁵ The van activities seemed to work well for the teacher participants in terms of the level of difficulty, the inquiry-based style, and the specific content addressed in the activities. In addition, the teachers gained experience using different types of equipment from the very basic and affordable to the more technical and expensive. Teachers often cited the inquiry approach as well as the experience with the equipment as the most positive aspects of the program. We asked teachers to rate various components of the van program on a scale of 1 to 5. We also asked the teachers to respond to open-ended questions. Responses to these questions were often the most interesting. On these questions many teachers stated that the Physics Van program would change the way they teach science. About half the teachers cited applying inquiry methods as the change in their teaching, while others cited the use of equipment as the major change.
