Evaluation of inclusive educational resources for teaching sound waves

Abstract It is known that blind and visually impaired (VI) students avoid choosing the Sciences and Technologies track in Secondary Education due to the inclusion challenges they faced in Basic Education, particularly the lack of adapted materials. To overcome this situation, investment in the development of tailored science materials is essential. This paper presents a study on the use of inclusive educational resources for sighted, blind, and VI students in a Portuguese middle school. The school integrates students with multiple disabilities alongside sighted students. The research focused on evaluating how 8th-grade students perceive the contents of sound waves using three inclusive educational resources. These resources were based on multisensory didactics—a tactile model, a slinky spring model, and a Swell paper model—and developed with inputs from VI students, blind students and teachers. These resources were tested with sighted students to assess their effectiveness in an inclusive setting. A questionnaire was administered to sighted students to analyse their perceptions of the inclusion of these materials in the classroom. The results revealed a high level of satisfaction, demonstrating that the multisensory approach enhanced students’ understanding of their own learning. Based on the findings, the study suggests expanding the research to include more blind and VI students and additional Physics resources.
