This study aims to reveal the contribution of the student achievement division (STAD) type
cooperative learning model in developing students ability to understand mathematical concepts. This is done
based on studies which state that the application of the STAD learning model improves students ability to
understand mathematical concepts, but has not revealed in detail this model in developing each indicator of
understanding mathematical concepts. This research is a literature study that discusses the syntax of STAD
learning models and indicators of understanding mathematical concepts. The results showed that the six-step
STAD learning model provided opportunities and was able to make student learning activities increase in
developing their ability to understand mathematical concepts, it can be concluded that the STAD learning
model contributes in developing students ability to understand mathematical concepts,
