The use of 3D printing in science, technology, en- gineering and mathematics (STEM) learning is a promising way for integrated STEM education. This study examined the influence of 3D printing infused STEM integration on students' interest in STEM ca- reers, which is essential for students to participate in STEM disciplines and future STEM careers. The participants included 26 teachers across six states in the United States and their 1455 students in primary and secondary classrooms. Teachers' lesson plans were analysed to examine the level of 3D printing and STEM integration. Students'

This paper addresses the need for enhancing our awareness of user‐centered design in educational technology through a more explicit and systematic alignment between the needs of educational technology users (learners and educators) and the affordances provided by the technology. First, we define the term “affordance” and discuss it from the perspectives of cognitive psychology and user interaction design. Next, we propose a taxonomy of functional affordances that builds on prior research and reflects the current trends in the design of educational technologies. The paper is concluded with an
