PENGENALAN KONSEP BANGUN RUANG PADA PESERTA DIDIK TUNANETRA DI SLB

Blind students have limitations in obtaining visual information. In general, they only use the senses that still function apart from sight, so that during learning they only rely on verbal explanations from the teacher and the help of concrete objects that can be touched. This research aims to describe the process of introducing the concept of geometry, and knowing the increase in learning outcomes and enthusiasm in learning with concrete objects as media. This research is a qualitative-descriptive type. Data collection is done by observation, documentation, and tests. The research subjects were all class VIII blind students at SLB Negeri Rasau Jaya. The results of the analysis show that the introduction of the spatial concept is carried out in three stages, namely the preliminary stage, the core activity, and the closing stage. The results also showed an average increase in learning outcomes of 33.33% after using concrete objects as media. In addition, blind students show positive enthusiasm in learning with the help of concrete objects.
