Examining the educational value of 3D LED fan displays. Results of a project

Abstract

Holography is an emerging technology with interesting educational potential. Although the cost of devices able to display holograms is significant, there are alternative methods for producing pseudo-holograms with far less cost, such as 3D LED fan displays. Because the research regarding the impact these devices have on learning is limited, we implemented a project in which we contrasted the learning outcomes produced by their use with that of 3D models presented using computers. Following a between-subjects research design, 174 primary school students aged 10 to 12 were recruited, divided into two groups (each used the aforementioned devices/media). Our data analyses demonstrated that students’ performance was better in the pseudo-holograms group. Moreover, students in this group enjoyed the learning process, were motivated to learn, and felt that the pseudo-holograms facilitated their learning. On the basis of these results, we argue that 3D LED fan displays and pseudo-holograms offer positive learning experiences and an attractive method for presenting the learning content. Then again, as the relevant technology is still evolving, more studies are needed for establishing their educational value.
