Improving the Ability to Calculate Addition Using Stick Numbers for Deaf Students at Special Schools in Bima City

Abstract

This study examines the low numeracy skills of deaf students in Mathematics at SLB Negeri 1 Kota Bima.  The formulation of the problem of this research is "How is the description of the increase in arithmetic addition operations ability through stick numbers in class III deaf students at SLB Negeri 1 Kota Bima?"  The formulation of the problem of this research is "How is the description of the increase in the operational ability to count addition using stick numbers in deaf students in class III at SLB Negeri 1 Kota Bima" The purpose of this study was to determine (1) the ability to calculate addition to research subjects (AV) before being given Baseline treatment  1 (A1) or before the use of the Stick the value in the category is still very low.  (2) The use of stick numbers to increase the numeracy ability of research subjects (AV) while being given Intervention treatment (B) or when using stick numbers the value is in the very good category.  (3) The ability to calculate the sum of the research subjects (AV) after being given Baseline 2 (A2) treatment after using the Stick scores are in the good category.
