Peningkatan Kemampuan Menyelesaikan Soal Cerita Matematika Melalui Penerapan Langkah Polya dalam Model Problem Based Learning

Abstract

Students at UPT SD Negeri Babadan 01 Wlingi District, Blitar Regency have difficulty working
on math word problems, but if they are given questions with numbers they can do them. One of the
influencing factors is the difficulty of changing the verbal sentence in the problem into a mathematical
model and the ability to understand word problems. The purpose of this research is to improve the
ability to solve math word problems through the application of Polya steps in the Problem Based
Learning Model. This type of research is classroom action research (CAR). The design of this study
refers to the class action research (PTK) design of Kemmis and Mc. Taggart namely (1) planning, (2)
implementing actions, (3) observation and (4) reflection. This research was conducted in two cycles.
The results of this study indicate that the application of Polya's steps in the Problem Based Learning
model can improve students' ability to solve math word problems. The 4 steps of Polya are: (1)
understanding the problem, (2) making a plan, (3) carrying out the plan, (4) re-examining the process
and the results obtained. The results showed that there was an increase in the ability to solve math
word problems seen from the LKPD cycle 1 by 53% and in cycle 2 it became 90%
