The Effect of Scientific Approach Contextual Teaching and Learning on Students' Mathematical Power

Abstract

Unlike traditional learning models, this study aimed to evaluate the effects of applying a scientific method that incorporates CTL (Contextual Teaching and Learning) on students' mathematical ability. A quasi-experimental study with a posttest-only control group design was the research methodology employed. There were 200 pupils in grade VIII at SMPK Immaculata Ruteng who made up the study population. Class VIII D (33 students) was the experimental class that utilized the CTL-based scientific method, while class VIII F (34 students) was the control class that followed the traditional learning paradigm. Sampling was done at random. A multiplechoice test was the research tool employed, and the t-test was used to analyze the results. At the 5% significance level, the t-table was 1.668 according to the analysis results, and the t-count value was 5.114. The rejection of H0 (the null hypothesis) is possible when taking into account the decision rule where thitung > ttabel. Therefore, it can be said that students' mathematical proficiency is greatly impacted by the use of a CTL-based scientific method
