The Effect of The Trisuis-Assisted Core Learning Model on The Mathematical Problem-Solving Ability of Students of SMKN 1 Majalengka

Abstract

The background of this research is the fact that students' mathematical problem-solving abilities are not optimal and need to be further improved. One of the learning models that can improve students' mathematical problem- solving abilities is the Connecting, Organizing, Reflecting, and Extending (CORE) learning model. The purpose of this study was to determine the effect of the CORE learning model assisted by TRISUIS on the mathematical problem-solving abilities of grade X students at SMKN 1 Majalengka with the subject of trigonometry. The next step was to test the differences in mathematical problem-solving abilities between students who applied the CORE learning model assisted by TRISUIS and students who applied the conventional learning model. This study used a quantitative approach with a quasi-experimental research method with a pretest-posttest control group design using an experimental class and a control class. The results of this study indicate that there is a difference in the average score of mathematical problem-solving abilities in the experimental class that applied the CORE learning model assisted by TRISUIS, which is higher than the control class that applied the conventional learning model.
