PENGARUH MODEL PEMBELAJARAN TREFFINGER TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA KELAS VIII SMP NEGERI 22 PESAWARAN

Abstract

This study aims to find out how the Treffinger learning model can affect the mathematical problem solving abilities of eighth grade students in the odd semester of SMP Negeri 22 Pesawaran in the 2021/2022 academic year with problems in the form of less than optimal mathematical problem solving abilities. This research is an experimental study using two class samples, namely class VIII.a as the experimental class and VIII.b as the control class. This sample was determined using the Cluster Random Sampling technique with a lottery procedure, where each class consisted of 32 students. The effect of the treatment given is seen through a mathematical problem solving ability test in the form of an essay as many as 5 questions which are analyzed by hypothesis testing using t-test. Based on the results of the research conducted, it was obtained and for a significant level of 5%. Thus, it is rejected, meaning it is accepted or it can be said that the average mathematical problem solving ability of students using the Treffinger learning model is greater than the average mathematical problem solving ability of students using the conventional learning model. Thus, because the application of the Treffinger model has a positive effect on students' mathematical problem solving abilities.
