Development of Learning Tools Based on Online Realistic Mathematics Education to Improve Critical Thinking Ability and Adversity Quotient of Students in MAN 1 Medan

Abstract

This study aims to: 1) to produce online learning tools based on realistic mathematics education (valid, practical, and effective) for 1st grade of MAN 1 Medan students; 2) to analyze the improvement of students' critical thinking ability after being taught by using online learning tools based on the realistic mathematics education for 1st grade of MAN 1 Medan; 3) to analyze the achievement of the adversity quotient of students after using online learning tools based on the realistic mathematics education in 1st grade of MAN 1 Medan. The subjects in this study were students 1st grade of MAN 1 Medan in the 2020/2021 school year. The results showed that: 1) Students' mathematical critical thinking ability using online learning tools based on the realistic mathematics education increased in terms of: The average posttest score of the first test was 73,07 increased to 87,60 and the N-Gain test I was 0,3 in the low category increased to 0,6 in the medium category in test II; 2) The ability of Adversity Quotient increased in terms of: the average ARP (Adversity Response Profile) results of the students in the first test of 125,43 increased to 154,13 in the second test, an increase of 28,70; 3) Learning tools developed based on online assisted realistic mathematics education have met the criteria of validity, practicality, and effectiveness.
