PENERAPAN MODEL PROBLEM BASED LEARNING UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS DAN HASIL BELAJAR MATEMATIKA SISWA KELAS IV SDN TINGKIR TENGAH 02

This research aims to improve critical thinking skills and mathematics learning outcomes of grade IV students of SDN Tingkir Tengah 02. The subjects used in this study were 26 grade IV students consisting of 13 male students and 13 female students. The data collection technique carried out is using a test technique in the form of evaluation questions that have been tested for validity and reliability, then there is a non-test technique in the form of an observation sheet to assess learning activities using Problem Based Learning. The data obtained from the implementation of learning were analyzed descriptively. The results of the research conducted showed that there was an increase in students' critical thinking skills, where in cycle 1 there were 20 students (77%) who had a high category of critical thinking skills and in cycle 2 there were 23 students (88.5%). In addition, student learning outcomes have also improved, where in cycle 1 there are 18 students (69%) who complete and in cycle 2 there are 23 students (88.5%). So based on the results of the above data analysis, it can be concluded that the application of the Problem Based Learning model is able to improve the critical thinking skills and mathematics learning outcomes of grade IV students of SDN Tingkir Tengah 02.
