This article describes how High School Visual Arts Teacher Jethro Gillespie built a portable art gallery for his students--essentially an 8-foot cube made from plywood and lightweight boards that can be assembled with bolts and taken apart in sections. The ceiling pieces of the gallery have track lights, the interior walls have been painted gray, and the exterior walls have been painted black with chalkboard paint. The whole gallery can fit in the back of a pickup truck and can be assembled or disassembled in less than 30 minutes. The article focuses on how Gillespie's AP Studio Art students used the portable art gallery to exhibit their artwork. Specifically, his students were able to dovetail having their own art show with the Concentration portion of their AP exam, which asks students to create a "body of related works that demonstrate a student's commitment to the thoughtful investigation of a specific visual idea" (AP Studio Art course description, p. 22). Students' experiences with the gallery helped them each to conceptualize, develop, and display a body of their artwork, which then culminated in an artist reception event.
