<![CDATA[Abstract : The Application of Scientific Approach Using Audio Visual Media in Improving Mathematics Learning about Geometry for The Fifth Grade Student of SD Negeri 5 Bumirejo in Academic Year 2014/2015. The objective of this research is to improving mathematics learning about geometry. The subjects were fifth grade students of state elementary school 5 Bumirejo totaling 35 students. Clasrooms Action Research was conducted in three cycles. Each cycle there were two meetings that consist of planning, action, observation, and reflection. Data collection techniques used testing, observation and interviews. The validity of data used triangulation techniques and triangulation of data sources. Data analysis applied the analysis of qualitative data and quantitative data. The results showed the application of Scientific Approach with Audio Visual Media can improve mathematics learning about geometry for fifth grade student of elementary school.
