Abstract

This experimental research aims to determine the effect of using audio-visual media through a documentary film on the ability of understanding mathematical concepts. The benefits of the audio-visual media through documentaries to facilitate learners in understanding the subject matter to be studied. The design used was experimental design true experimental design with posttest only control the shape design. This research was conducted among students of class VII in SMP Maria Media trix which is located at Jln.
