摘要：The objectives of this study are (1) to examine the quality of learning with Openended Mathematical Modeling towards mathematical reasoning ability;(2) describe the achievement of mathematical reasoning abilities in terms of selfconfidence.The research method used is a mix method with concurrent embedded design.The research subjects were students of 1st Public High School in Payung class Science of 11th grade.The quantitative research is true experimental research with Pretest-Posttest Control Group design.Quantitative data were tested with the z test,while qualitative data were analyzed descriptively.The results showed that (1) learning with Mathematical Modeling with Open-ended approach gave good quality;(2) students with low self-confidence can estimate the allegations and check the truth of the statement well but cannot draw conclusions logically,students with self-confidence are able to check the truth of the statement,provide an explanation of the picture and estimate the allegation but still make a little mistake in drawing conclusions logically,students with high self-confidence can check the truth,draw conclusions,estimate allegations very well,but make a few mistakes in giving explanations from images,the indicators of giving explanations from images are the most difficult indicators to be achieved by students in all categories of self-confidence.
