The effect of 3D Printing technology on primary school students’ content knowledge, anxiety and interest toward science

3D printing (3DP) technology can serve as a powerful learning and educational tool that can support and inspire students’ creativity. This study investigates the effect of an experimental educational scenario, focused on 3DP and design printing, on students’ conceptual understanding, interest and anxiety. The study’s sample included 111 primary school students divided into two group: The Experimental Group which used 3DP technology and the Control Group which used everyday materials. Students in both groups were taught the concept of friction, and the factors it depends on via a constructivist teaching approach. The study’s results demonstrate the positive effect of 3DP technology on students’ conceptual understanding of the force of friction. Additionally, students’ interest in science was not affected in any negative manner and students’ anxiety was curbed. This study provides implications and limitations for 3D printing integration in STEM education.
