The main purpose of the living technology curriculum is to cultivate students' interest in learning science and technology, and further to utilize their experience of learning instructions and develop their ability to integrate interdisciplinary knowledge and skills. In recent years, as countries have begun to emphasize the concept of interdisciplinary integration in the school education, STEM (Science, Technology, Engineering, and Mathematics, STEM) focuses on cultivating interdisciplinary talents. With this, STEAM highlights the role of ART because other dimensions of STEM are expected to be effectively integrated through the cultivation of aesthetics; the purpose of this study is to design a STEAM curriculum for elementary school children and to explore the impact of STEAM education on the creativity. The content of this course is based on the PBL (Project-Based Learning) with the teaching activities combining with "Chinese Paper-cutting" and "BBC micro: bit". The teaching process is used the strategy of creative thinking instruction. The research method adopts a one-group pretest-posttest design based on a purposive sampling of 21 students from one class in an elementary school. The research tools included the records of learning feedback and the creativity assessment. The empirical findings show that the project-based learning incorporating STEAM activity has a positive significant influence on students' development of creative recognition. Since the empirical results are constricted by the short-term STEAM course, the STEAM course with the art-oriented still benefits the STEAM education and Learning effectiveness of elementary school students. The implication of interdisciplinary interactive Lamp of Paper Carving with Micro:Bit is expected to contribute to further development of STEAM course. Since the curriculum is only last for few weeks, it is too short to affect the emotional facet of creativity. Future researches are suggested to extend the teaching period and evaluate the long-term influence of PBL STEAM on students' learning attitude.
