The emergence of 3D printing has raised hopes and concerns about how it can be used effectively as an educational technology in school classrooms. This paper presents the results of a survey asking teachers from multiple grade levels and subject fields about the impact of 3D projects on student learning. Teachers were asked about the kinds of 3D projects they were doing with students and what skills or knowledge students were developing by participating in those projects. Participants reported that their students developed a number of skills while working on 3D printing projects, including 3D modeling, creativity, technology literacy, problem-solving, self-directed learning, critical thinking, and perseverance. Parallels between teacher-identified skills and widely cited lists of 21st-century skills suggest that 3D projects are a promising approach to preparing students for life and work in a digital age. 相似文献

The purpose of this case series was to explore whether adults who did not have the opportunity to acquire reading skills during childhood are able to do so rapidly if trained with an adequate literacy program. After 14 weeks of training with a new, optimized, literacy course based on cognitive research, six out of eight participants became able to read words they had never encountered, hence demonstrating that they were definitely engaged in decoding processes that allow autonomous reading. Moreover, they showed enhanced phonemic sensitivity and phonological memory. The latter finding implies that functional changes can take place rapidly outside the reading domain even when reading is acquired in adulthood. Thus, there is no major plasticity impediment preventing rapid eradication of illiteracy in adults. 相似文献
