The Effect of the Blended Learning Model on Mathematical Reasoning Ability in the Material of Lines and Angles

Abstract

This quasi-experimental research aimed to enhance mathematical reasoning abilities among students at SMPN 2 Lemahsugih Majalengka by implementing a blended learning model. The study involved 60 students from two classes, with 30 students in the experimental class (VII A) receiving the blended learning treatment and achieving an average score of 77.5. The control class (VII B) consisted of 30 students who received online learning treatment and obtained an average score of 67.17. The research utilized a valid essay questionnaire consisting of seven questions to assess learning outcomes in the topic of lines and angles. Data analysis involved normality and homogeneity tests, which confirmed that the data was normally distributed and homogenous. Subsequently, a hypothesis test was conducted, revealing a significant difference in mathematical reasoning abilities between students who learned using the blended learning model and those who received online learning. This research underscores the effectiveness of blended learning in improving students' mathematical reasoning skills in the context of lines and angles.
