With the advance of the Maker movement, teacher professional development is needed to prepare K-12 teachers for maker-centered instruction. This study examined the influence of teaching experience in learning maker-centered instruction. Data included surveys, 3D models, and maker lesson plans created by 162 in-service K-12 teachers. Results show that, overall, years of teaching experience did not make a difference in knowledge, attitudes, and design of maker lessons between veteran and novice teachers. Both teacher groups held positive attitudes, yet were concerned with limited maker knowledge and skills. After the initial training, both groups were able to integrate maker technology and design maker lessons in creative ways. Research and practical implications are discussed for the maker-teacher professional development of K-12 teachers.
