The purpose of this study was to describe the process of students' mathematical connections in solving mathematical problems in terms of learning styles. The type of research used is descriptive research with a qualitative approach. The research subjects were six students consisting of two students who have a visual learning style, two students who have an auditory learning style, and two students who have a kinesthetic learning style. Student learning style data were collected through learning style questionnaires, while student connection process data were collected through mathematical connection test sheets and interviews. Data credibility is done by triangulating sources and methods. Data from the six subjects consisting of two students for each of these learning styles were described and categorized from the same, different, and specific views. The subjects obtained from the results of the learning style questionnaire were compared using the results of the mathematical connection test and interviews. Data analysis was guided by four steps to solve Polya's problems and was carried out in three stages, namely data condensation, data presentation, and conclusions. The results showed that there are differences in the mathematical connection process carried out by students who have visual, auditory, and kinesthetic learning styles in the step of understanding the problem. However, there are similarities in the mathematical connection process carried out by students who have visual and kinesthetic learning styles at the step of compiling a completion plan and checking again. while students who have a different auditory learning style from students who have visual and kinesthetic learning styles in implementing the completion plan and re-checking. The process of mathematical connection of students who have an auditory learning style at the step of checking back cannot be seen, because these students do not take this step when solving problems. Researchers suggest that teachers need to accustom students to connecting mathematics both internally and externally and pay attention to the emphasis of the material given to students so that students' mathematical connections are more developed. because the student did not take this step when solving the problem.

Mathematical Connection

Mathematical connection ability is one of the abilities needed in solving mathematical problems. In solving problems, each student has a different way of solving it. This is due to the variety of intelligence that the students possess. This intelligence is known as Adversity Quotient (AQ). There are three levels of AQ namely climbers, campers, and quitters. This study aimed to describe the students' mathematical connections ability in solving mathematical problems related to their AQ. This research is a descriptive study with a qualitative approach carried out in Class IX of MTs Negeri Gresik consisting of three students who have different levels of AQ. The research instrument used consisted of the Adversity Response Profile (ARP) questionnaire, problem solving Test, and interview guidelines. The results of this study indicate that: at the stage of understanding the problem, climbers and campers students could retell with their language different from quitters students who change the language of questions with different meanings, at the stage of preparing a plan, climbers students understand the relationship of problems with mathematical concepts and life everyday and plan quite coherently and clearly while students campers and quitters understand the relationship of problems with mathematical concepts and everyday life and plan quite well, at the stage of implementing the plan, climbers and campers students could find the right answers while students quitters find the answers that are not yet correct, in the stage of looking back, climbers students do the checking again so that they could give the right conclusions while the campers and quitters students do not do the checks again but could provide conclusions that are quite precise.
