Discovery Learning Based Ecosystem Student Work Sheet to Improve Problem Solving Ability of Students in Class X MA

Abstract

Problem solving ability is an important aspect to be improved in learning mathematics. One effort to improve problem-solving skills is to apply Discovery Learning -based Student Worksheet assisted learning. The purpose of this study was to analyze the increase in students' problem-solving skills through Discovery Learning-based Student Worksheet assisted learning. This type of research is quantitative with the One Group Pretest Posttest design which is used to compare the level of problem solving ability before and after treatment. The subject of this research involved 25 class X MAN 2 Labuhan Batu Utara students. This subject will receive learning treatment with Discovery Learning-based Student Worksheets. This study uses test instruments and interviews for data collection. Test data collection was carried out 2 times, namely the initial test before treatment (pretest) and the final test after treatment (posttest). Data analysis of pretest and posttest results was carried out by t-test and normalized gain. The results showed that mathematics learning assisted by Discovery Learning-based Student Worksheets could increase students' problem-solving abilities by 0.465 in the moderate category.
