The purpose of this study is to describe the effect of reflective learning on mathematical reasoning abilities of mathematics students, and to analyze whether there is an interaction between reflective learning on the initial mathematical ability on mathematical reasoning abilities of mathematical students. The method used in this study is quasy experiment, in this case comparing between students who are taught by using reflective learning models with conventional learning. From the results of data analysis several conclusions can be drawn (1) Based on the results of the average similarity test where the t test value of 9.261 with the value of sig. = 0.000 smaller than α = 0.05 so that there is a significant difference between the average mathematical reasoning ability of experimental class students and the control class, therefore it is concluded that there is an influence of reflective learning models on mathematical reasoning ability of students of Mathematics and Natural Sciences Faculty of Pamulang University. (2) Based on the Anava test results F = 11,311 with a significance of 0,000 less than α = 0.05, then rejecting H0 is an interaction between the reflective learning models applied to students with high, medium, and low initial ability towards students' mathematical reasoning abilities Faculty of Mathematics and Natural Sciences Pamulang University.
