PENINGKATAN HASIL BELAJAR PESERTA DIDIK KELAS 4 SEKOLAH DASAR PADA MATERI LUAS DAN KELILING PERSEGI PANJANG MENGGUNAKAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL)

Abstract

This study aims to describe the process of improving the learning outcomes of fourth-grade
students in the topic of area and perimeter of a rectangle using the problem-based learning (PBL)
model. This research is a classroom action research conducted in two cycles, following the Kemmis
and Taggart model. The results of the study show that the problem-based learning (PBL) model can
improve the learning outcomes of fourth-grade students in the topic of area and perimeter of a
rectangle. This is evidenced by the post-test scores of the students at the end of each cycle. The
increase in the average percentage of students who achieved learning mastery in Cycle 1 increased
by 49% from 23% in the pre-cycle to 72%. Meanwhile, the average percentage of students in Cycle 2
increased by 11% from 72% in Cycle 1 to 83%. These results indicate the achievement of the research
success indicators. Therefore, it is proven that the implementation of the problem-based learning
(PBL) model can improve the learning outcomes of fourth-grade students in the topic of area and
perimeter of a rectangle.
