The purpose of this study is to find out the improvement of mathematical learning outcomes through mnemonic techniques. This research includes class action research (CAR) which lasts for two cycles. Students class VIIA MTs Muhammadiyah Syuhada Kota Makassar is the subject of this research. Tests of learning outcomes and observation guidelines are instruments used in this study. Descriptive analysis is a data analysis technique used in this study. Descriptive analysis results show an increase of 1.45, with the average value outcome of learning mathematics after application of mnemonic techniques in cycle I is 74.55 and in cycle II is 76. The completion of learning outcomes also increased by 10.70%, the completion in cycle I by 71.40% and in cycle II by 82.10%. It can be concluded that mnemonic techniques are able to improve students' memory in learning so that the material that has been obtained before is not easily forgotten.
