In Taiwan, many technology teachers believe that they can help in improving students' career interest in technology through providing them with many hands-on learning activities in one semester. However, some technology teacher educators or teachers believe that we should provide in-depth hands-on learning experiences instead of experiential hands-on activities. In this research, I will introduce the development and implementation of new technology curriculum in Taiwan in first. Then I will introduce the key ideal of Less is More. I will share how do we provide in-depth hands-on learning experiences for students by using 3D printing technology and repetitive modeling. In 2021, we published a paper of "Developing Student Imagination and Career Interest through a STEM Project Using 3D Printing with Repetitive Modeling" in the journal of "Interactive Learning Environment." In this study, we explore the use of 3D printing machines in technology and engineering education. We developed a STEM-based vibration isolator activity using a 3D printer and repetitive modeling. A nonequivalent control group design was employed in this research, and 192 Taiwanese high school students participated in this study. The conclusions are: (1) repetitive modeling in the STEM-based design activity enhanced student imagination; (2) repetitive modeling was effective in developing high school students’ interest in technology and engineering careers. According to the results of this study, I will share how should we arrange the in-depth hands-on learning experiences in technology education or STEM education. Most importantly,  we need to rethink about the ideal of Less is More, and let our students have the chance to explore their real interests in technology education.
