This study aims to determine the effect of problem solving models on the ability of mathematical connections and self-efficacy. This type of research is a quasi-experimental study. The instrument used consisted of tests of mathematical connection ability, self-efficacy questionnaires, student activity sheets, and mathematical initial abilities. The population of this study was students in grades VII-1 and VII-2 in SMP Negeri 5 Tebing Tinggi. The instrument of this research was in the form of a mathematical connection ability test of 4 items in the description and self-efficacy questionnaire in students of 23 statements with 4 alternative answers. It can be seen that the Fcount value is 51.76 and the significance value α = 0.000. So the level of significance value <0.050 (sig. <0.050) then H_n is rejected and H₁ is accepted. However, if the significance> 0.050 (sig.> 0.050) then H_n is accepted and H₁ is rejected. Problem solving model is smaller than α = 0.05 then H_n is rejected and Ha is accepted. So that there is an influence of problem solving models on students' mathematical connection abilities accepted. obtained a value of F_n (B) of 19.81, if the value of F_n (B) is confirmed to the value of F table at α = 5%, then F_n (B) is greater than F table (19.81> 4.006). It was concluded that enough evidence to reject H_n. This means that there is an influence of the learning approach on students' mathematical self-efficacy. Furthermore, a F_n (A) value of 11,798 is obtained, if this F_n (A) value is confirmed to the value of Ftable at α = 5%, then F_n (A) is greater than Ftable (11,798> 4,006). It was concluded that enough evidence to reject H_n. This means that there is an influence of KAM on students' mathematical self-efficacy. Based on the calculation results obtained that the significance value of KAM * Learning towards students' mathematical connection ability is equal to 0.4280, greater than the predetermined significance level, that is, 0.05 (0.4280> 0.05), which means that is accept H_n. In other words there is no significant interaction between the learning model and the initial mathematical ability of students' mathematical connection abilities. Likewise with student self-efficacy, the results of data analysis obtained for the KAM significance value * Learning towards students' self-efficacy is 0.4801, greater than 0.05 (0, 4801> 0.05), so H_n is accepted which it means that there is no significant interaction between learning models and mathematical initial abilities of students' self-efficacy.
