SINGLE SUBJECT RESEARCH: INCREASING MATHEMATICS LEARNING OUTCOMES OF THE ADDITIVE FRACTIONS USING FRACTIONAL BLOCK MEDIA TOWARD STUDENTS WITH VISUAL IMPAIRMENT

The purpose of this study is to determine the effectiveness of using the beam media on fractions students with visual impairment to improve the learning outcomes about mathematical summation material on fractions students in YKAB special schools (SLB) Surakarta. The research method which is used in this study is single subject research design experimental that is design A-B-A (Baseline-1 - Intervention - Baseline-2) with the subject is chosen directly by the researchers based on the need of two students on a 4th grade of special school. The Techniques of analysing data used are statistical analysis and visual analysis. Statistical analysis is in the form of charting a simple statistic description of Antam. Visual analysis focuses on changes in one variable and two conditions (results) that change all the intervention phase and the changing compared with the baseline phase. Based on data analysis from all three phases, it is known that the using of fractional block media provides positive influence on mathematics learning outcome fractions summation material of students with visual impairment. Based on these results, we can conclude that fractional block is an effective media to improve the learning outcomes about fraction summation material for fourth grade students with visual impairment.
