  Science, Technology, Engineering, and Mathematics classes are mainly taught
using visual supports. However, the advancement of technology and the
increasing eforts to equip schools with digital instrumentation have opened up
the possibility of exploring new teaching avenues, such as sonifcation. We
explored the efcacy of sonifcation in education using a novel interactive tool,
Edukoi, in the context of astronomy, which is predominantly disseminated
through spectacular images, animations, and visuals. Edukoi is a motion-sensing
sonifcation tool that converts images to sound in real-time for educational
applications. Our study, conducted with nearly 150 middle-school students,
included a preliminary questionnaire investigating the perception, engagement,
and motivation of students towards science; two sessions dedicated to testing
Edukoi and assessing the potentiality of the software for the recognition of
the colour and the shape of real and sketchy images; and a fnal second
administration of the questionnaire to capture a possible benefcial efect of
the use of the tool in the engagement towards science. Results showed the
efectiveness of Edukoi in colour recognition and reasonable efcacy in shape
identifcation. Although the questionnaire did not reveal an increment in
science engagement over the time of the study, oral feedback from the students
was positive. Edukoi presents a possible alternative teaching aid, potentially
benefting diverse learners, including the visually impaired. Further
developments of the software are needed to enhance its efectiveness in
conveying more complex features such as composite colours or shapes.
