The Effect Of The Problem Based Learning Model On Students' Reasoning Abilities In Solving Story Problems On The SPLDV Material For Grade VIII

Abstract

The purpose of this study was to determine the effect of the Problem-Based Learning Model on students' reasoning ability in solving story problems in class VIII at the UPTD of SMP N 2 Pematang Siantar. The study used a pre-experimental design with classes VIII-8 as subjects, and the author employed a quantitative approach. The design used by the researcher was a One-Shot Case Study. Based on the results of data analysis and discussion, it can be concluded that the use of the Problem-Based Learning Model has a positive and significant effect on students' reasoning ability in solving story problems in class VIII at the UPTD of SMP N 2 Pematang Siantar in the 2025/2026 academic year. A positive influence is shown through the regression equation where Y = 40.826 + 1.168 where the b value = 1.168. This influence is shown through the T-Test with Tcount > Ttable (3.926 > 1.701) or (sig.) < 0.05 (0.000 < 0.05) then Ho is rejected and Ha is accepted which means there is a positive and significant influence of the Problem Based Learning Model on Students' Reasoning Ability in solving story problems on the SPLDV material. The contribution of variable X (Problem Based Learning Model) to variable Y (Student Reasoning Ability) is 67.4%.
