This study aims to find out the increase of student’s ability in mathematical exploration, learning completeness, and the relationship between mathematical exploration abilities and students' self-confidence in the application of the probing prompting learning model. This is an experimental research method with One Group Pretest-Posttest Design. The data was collected by giving a test about mathematical exploration abilities and a questionnaire on self-confidence. The results of the study by applying the probing prompting learning model showed that there was an increase on student’s mathematical exploration ability at 0.806 with a high category. Students’ self-confidence achievement showed that there was no tendency towards the established self-confidence indicators. The achievement of individual learning completeness was ?75% and classical learning completeness was ? 75% in average. There is a relationship between mathematical exploration abilities and student self-confidence, the correlation coefficient is 0.204 with weak criteria.
