Then the data were analyzed using the Miles and Huberman model which included data reduction,data presentation, and conclusions. The results showed that (1) Students with high learning independence met the indicators of concept understanding ability, namely being able to re-explain an understood concept, able to classify objects based on their properties, able to present understood concepts to share mathematical representations, and finally able to solve a problem by applying the concept. (2) Students with learning independence are meeting the indicators of concept understanding ability, namely being able to re-explain a concept that is understood, able to classify objects based on their properties, able to present understood concepts to share mathematical representations. (3) Students with low learning independence meet the indicators of concept understanding ability, namely being able to re-explain a concept that is understood, able to classify objects based on their properties.
