THE EFFECT OF THE LET’S READ APPLICATION TO STUDENTS' CRITICAL THINKING ABILITIES FOR ELEMENTARY SCHOOL

Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) learning model assisted by Let's Read media on students' critical thinking skills in the Javanese language subject of grade IV SDN Teguhan 02. The background of this study is the still low implementation of learning that encourages critical thinking in elementary schools. The study used a Posttest-Only Control Group Design with a saturated sampling technique, involving 34 students divided into an experimental class and a control class. The data collection instrument was a multiple-choice test of 20 questions given after the learning. The prerequisite test showed that the data were normally distributed and homogeneous. The t-test results showed a significance value of 0.000 < 0.05, which means there is a significant effect of the use of the PBL model assisted by Let's Read media on students' critical thinking skills. The average posttest score of the experimental class reached 81.76, higher than the control class which was only 63.24. This shows that the use of the PBL model with the help of interactive digital media such as Let's Read can significantly improve students' critical thinking skills.
