An analysis of mathematical representation ability middle school students on concept congruence on learning style

The ability of mathematical representation helps students solve problems in forms that are easy to understand and more concrete, so they can maximize their potential for achievement learning mathematics. purpose this study was describe the abilities junior high school on concept congruence terms styles. subjects were 35 grade VIII using a random sampling technique. Data collection carried out tests, style questionnaires, interviews. After that, it analyzed triangulation techniques determine validity data. results showed average, have very good visual with auditory, visual, kinesthetic styles because all questions correctly according indicators.
