Mathematical external connection ability is the ability to relate topics in mathematics to the other learning subject and daily problems. Sensing and intuition personality is a characteristic of students receive and process information. For this reason, personality types can influence mathematics learning and mathematical external connection ability. The main purpose of this research is analysis of students’ external connection skill that has sensing or intuition personality. This study method used was descriptive the qualitative method with four students of class VII in Junior High School. Subject selected using purposive sampling, each subject represents one personality and one indicator. The data from this research were obtained from questionnaires, mathematical connection external test, and interviews. The results obtained that intuition student can applying the concepts and mathematical procedure to other subjects, but sensing student difficulties. Both of sensing and intuiting can use mathematical relationship in everyday life problems.

Learning mathematics is related to the connection ability. The mathematical connection ability is needed by the students to connect each mathematical topic, the other learning subjects and daily problems. The personality types of sensing and intuiting is the ability to process information. Every student has a different in receiving and processing information. It is cause by personality type, which makes the mathematical internal connection ability of student different. The aim of the study is to describe student’s mathematical internal connection ability based on personality types of sensing and intuiting. This research used the qualitative method. Subject in this study were four students of class VII in Junior High School which selected using purposive sampling. The results obtained that the student with intuiting type has more mathematical internal connection ability than the student with sensing type. Based the result of the research, it can conclude that the student who can connect each concept in same topic in mathematics may not have the ability to connect each concept on the other topics. Most of the students were only implementing the formula taught at school. Students did not try to explore a concept to the other topic in mathematics.
