Pengaruh Model Pembelajaran Berbasis Masalah (Problem Based Learning) Dengan Tipe Group Investigation (GI) Terhadap Hasil Belajar Siswa

Abstract

This study aims to determine the effect of the problem based learning model with Group Investigation (GI) type on learning outcomes. This type of research is a quasy experiment in the form of nonequivalent control group design post-test only. The population in this study included all students of class X IPA MA Dakwah Islamiyah Putri Kediri. Taking by random sampling method, and selected class X IPA 1 as the experimental class and class X IPA 3 as the control class. Data collection was carried out using a test of learning outcomes in the form of a question description that had previously been validated. The results showed the average value in the experimental class = 75.45 higher than the control class = 61.81. T test results, yielding t = 3.61> t table = 1.671 means Ho is rejected. Based on these results it can be concluded that the application of the problem based learning model with Group Investigation (GI) type gives a better influence on the learning outcomes of the subject matter chemistry of electrolyte and non-electrolyte solutions in class X MA Dakwah Islamiyah Putri Kediri students.
