PENGARUH MODEL PEMBELAJARAN DOUBLE LOOP PROBLEM SOLVING (DLPS) TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA KELAS VIII SEMESTER GANJIL SMP NEGERI 20 BANDAR LAMPUNG TAHUN PELAJARAN 2021/2022

Abstract

: The problems in this study related to students' mathematical problem solving abilities are still low. This study aims to determine the effect of the Double Loop Problem Solving (DLPS) learning model on the mathematical problem solving ability of students of class VIII Odd Semester SMP Negeri 15 Bandar Lampung in the 2021/2022 academic year. The research method used is experiment. The population in this study were all eighth grade students of SMP Negeri 20 Bandar Lampung, with the sample selected using the cluster random sampling technique of 2 classes. The class is VIII C as the experimental class and class VIII B as the control class. Data collection was performed using a test technique in the form of essays consisting of 5 items that have been declared valid and reliability. The results of testing the hypothesis in this study using the t-hit formula. Based on the results of hypothesis testing using the t-hit statistical formula, the value of t = 4,09 was obtained. From the distribution table t at a significant level of 5% it is known t= =1,67 meaning t> tis 4,09> 1,67, so it can be concluded that "There is an influence of Double Loop Problem Solving (DLPS)  towards the problem solving ability of students of class VIII Odd Semester of SMP Negeri 20 Bandar Lampung in Academic Year 2021/2022 ".
