This study aims to determine: (1) the influence of open-ended approach to learning and conventional learning approach to students' mathematical reasoning. (2) mathematical reasoning abilities of students who have internal locus of control is better than students who have external locus of control on the open-ended approach to learning and conventional learning approach. (3) there is interaction between the learning approach with the locus of control that students have in influencing students' mathematical reasoning.
The population in this study are all SMP Negeri Lhokseumawe are selected by purposive sampling SMP 11 and SMP 13 as the sample and the class as a unit-extracted samples based on a random class with the students as many as 135 people. This research used quasi-experimental 2x2 factorial design.
Research instrument in this research is to use mathematical reasoning ability tests totaled six points in the form of descriptions about and locus of control in the form of questionnaires amounted to 12 grains statement. And reliability of each instrument at 0.923 and 0.611.
Based on the analysis of variance (ANOVA) found that: (1) there are significant differences in reasoning ability on learning approach with conventional open-ended. (2) there are significant differences in reasoning abilities in both types of locus of control. Mathematical reasoning abilities of students who have internal locus of control is better than an external locus control. (3) there is no interaction between learning approach with the locus of control 's students.
Based on the results of the study, researchers suggested that open-ended learning approach can be used as an alternative capable of learning to develop students' mathematical reasoning and is also able to gradually change an external locus of control students have an internal direction.
