TEACHING ON THE CONCEPT OF ENERGY TO STUDENTS WITH HEARING IMPAIRMENT: CHANGES OF ELECTRICAL ENERGY TO LIGHT AND HEAT

The purpose of this study was to determine the teaching on changing electrical energy into light and heat to students with hearing impairment (HI). We used quantitative and qualitative methods to 6 HI students in special school in Indonesia. In short, the experiments were done via the experimental demonstration to teach teaching materials about changing electrical energy into light and heat. To support the analysis, we conducted a pretest and posttest to determine changes in students' level of understanding. The results showed that the students' comprehension increased, showing the effectiveness of experimental demonstration for teaching students, although students with hearing impairments optimized their visual senses in the learning process only and they have difficulties on understanding complex and abstract information. Methods and media that suit their needs make the teaching process easier for them to understand the materials. The results of this study are expected to provide knowledge in how to make educators easier in teaching students with special needs, especially facing with science subjects.
