Abstract
Nanotechnology is one of the newly researchsubjects in the science field. School teachers teachstudents about the knowledge of nanotechnology;thus, developing appropriate instructional modulesof nanotechnology have become an important issue.In this paper, a Nanotechnology hands-on worksexhibition was held in the library of National TsingHua University, Taiwan. By problem-based learning,K-12 teachers design instructional activities to guidestudents on hands-on works using nanotechnologyconcepts. The problem-based learning achievementof K-12 teachers and students participating in thisscience activity was studied by giving pretest andpost test questionnaires.
