Learning Strategy of Production of Tempe Through Various Size of Soybean Particles for Students with Hearing Impairments

Abstract

The aim of this study was to find a strategy to teach how to make tempe in biotechnology materials through various particle sizes of soybeans to students with hearing impairments at the high school level. This research method used a single subject approach with pre-test and post-test designs with 10 students with hearing impairments, aged 19- 21 years, in Bandar Lampung, Indonesia. Learning strategies in the form of experimental demonstration, using the original media, and total communication (sign language, oral, speech reading, and writing). The results of the experiment showed that the more yeast used on the soybean particles, the more the fungus binds the soybeans, thus making the durability better. Teaching results show students with hearing impairments can understand all material about biotechnology in making tempe with various particle sizes. The experimental demonstration strategy provides concrete explanations about making tempe from various particle sizes of soybeans. Students' learning needs are well accommodated to provide a meaningful learning experience for students with hearing impairment.
