Science education practices for deaf and hard-of-hearing students in Indonesia

Introduction. Traditionally, the curriculum for deaf learners mainly involved language acquisition at the expense of other academic subjects. Currently, their subjects also include other disciplines, like science, to enrich students' knowledge related to human life. Objective. This study aims to describe the implementation of school science practices and identifies the challenges in improving science education in special schools for deaf and hard-of-hearing (DHH) students as a guide for improving inclusive education of these students. Methods. The sample included four principals and six classroom science teachers from five DHH schools, using purposive sampling in the five schools that provide education for DHH students in three regencies of Regional V Banyumas, Central Java, Indonesia. Data were gathered through interviews, field observations, and artifacts. Results. The teachers use various teaching strategies and rely on visual and handson activities for DHH students. The schools provide sign language interpreters and speech-development programs as support for teachers and DHH students. All teachers need professional development in teaching collaboration opportunities to develop their expertise in teaching DHH students. The policy implementation, instructional strategies, resources, and teacher qualifications were found to be extrinsic factors. Conclusion. The teachers need support from the government to include them in relevant training programs and prepare teachers with special or inclusive education knowledge by adding courses in university-level education for all prospective teachers. The results are insightful for DHH students, science educators, and policymakers.
