Abstract

This study aims to: 1) to determine the increase in creative thinking skills of students who are taught using learning tools developed using the discovery learning model; 2) to determine the increase in the problem-solving abilities of students who are taught using learning tools developed using the Discovery Learning model; 3) to determine the validity, practicality and effectiveness of learning tools developed using the discovery learning model. The subjects of this study were VIII grade junior high school students of Al-Hikmah Medan in the 2020/2021 academic year. The results showed that: 1) the mathematical creative thinking ability of students using learning tools with the discovery learning model increased in terms of: The average posttest score of the first test was 76.88, increased to 80.94 in the second test and experienced an increase in stage the spread of 88.75 and the N-Gain test I of 0.30 in the medium category increased to 0.33 in the medium category in the second test and at the distribution stage it increased to 0.62 in the moderate category; 2) the mathematical problem solving ability of students using learning tools with the Discovery Learning model increased in terms of: the average posttest score of the first test was 76.88, increased to 81.19 in the second test and experienced an increase in the distribution stage of 84.38 and N-Gain in the first test of 0.31 in the moderate category, increasing to 0.33 in the medium category in the second test and at the distribution stage, increasing to 0.42 in the moderate category; 3) the learning tools developed with the Discovery Learning Model have met the criteria of validity, practicality, and effectiveness Keywords: discovery learning model-based learning, mathematical creative thinking ability, mathematical problem solving ability, mathematics learning tools DOI: 10.7176/JEP/12-2-12 Publication date: January 31 st 2021

Highlights

Education is very much needed in the life of Indonesian society in improving the quality of human resources
The results showed that students with the ability to think creatively in the high category were 20% of the total number of students, the moderate category was 33.33% and the low category was 46.67%
The data obtained were analyzed and directed to answer the question whether the instrument and the learning roles using the Discovery Learning model that was developed met the criteria for validity, practicality and effectiveness

Summary

Introduction

Education is very much needed in the life of Indonesian society in improving the quality of human resources. An educated society is expected to be able to compete with countries in a world full of competition. Dumciuviene (2015) said, "Future growth of the country will depend on knowledge In this case more jobs will require a higher education qualification ”. This implies that the future growth of a country depends on knowledge In this case, many jobs will require higher educational qualifications. The same thing was conveyed by Muhardi (2004) that education has a very valuable and significant contribution in improving the quality of a nation, for the Indonesian nation
