Improving Mathematic Learning Achievement Using Abacus Counting Tool for Down Syndrome Children in The 3rd Grade of SLBP Putra Harapan Gondang Sragen, Central Java, Indonesia in The School Year Of 2015/2016

Abstract

This research aims to improve the learning achievement of mathematic arithmetic material for the 3rd Down syndrome graders in SLBP Putra Harapan Gondang Sragen in the school year of 2015/2016 using abacus tool. The research approach used was Classroom Action Research (CAR). The subject of research was the 3rd Down syndrome graders in SLBP Putra Harapan Gondang Sragen in school year of 2015/2016, consisting of 4 students. Techniques of collecting data used in this research were documentation, test, and observation result. Technique of analyzing data used was an interactive model of analysis, by comparing the original data before and after action through 2 cycles. The result of research showed that the mean learning outcome score of the 3rd graders was 45.00 in prior condition, 50.00 in cycle I, and 60 in cycle II. From this result, it could be said that there was an improvement of arithmetic ability in the children with Down syndrome with scores of 50.00 in cycle I and 60.00 in cycle Ii. The condition of the 3rd graders in prior condition before the research was conducted was because teacher had not used learning media optimally so that the mathematic learning outcome of the 3rd graders was low. Teacher delivered mathematic learning using abacus counting tool in the material of summing 1-10. The abacus counting media successfully improved the mathematic learning outcome from prior condition to cycle II. The result of research showed that there was an improvement of mathematic learning achievement in cycle I, but it had not fulfilled the target so that it was followed with cycle II; the result of research on cycle II showed that the mathematic learning achievement had met the intended target. Thus, it could be concluded that mathematic learning using abacus tool had successfully improve the learning achievement of the 3rd down syndrome graders in SLB Putra Harapan Gondang Sragen in the school year of 2015/2016.
