Abstract

The Low Mathematical Connection Ability (MCA) of students is the main problem of research. Problems in the field of students are less able to connect mathematical concepts/ideas in mathematical problem solving. Thus a learning approach is needed that spurs students to solve problems with flexibility, namely learning with an open-ended approach. The purpose of this study was to determine the improvement of MCA of junior high school students through an open-ended approach. To achieve this goal, a quasi-experimental study was conducted with a pretest posttest control group design. The study population was seventh grade students of SMP Negeri 5 Padangsidimpuan . Through cluster random sampling selected students of class VII-5 as the experimental class and students of class VII-6 as the control class. The research conducted shows the results through the Independent Samples Test obtained the significance of the results of the pretest and posttest of  0.004, which means that there are differences between the MCA students in the experimental class and the control class. Furthermore, through the N-gain test the average N-gain class experiment value was 0.48, which means that the value of improvement was in the medium category and in the control class the N-gain value was 0.28 which means it was in the low category. Thus it was concluded that the MCA students through the open-ended approach differed significantly from the MCA students with the conventional approach and the MCA students who were given the open-ended learning approach better than the MCA students with the conventional approach.
