Problem Based Learning and Their Effect on Learning Outcomes Estimation of Calculation Operations Number in Elementary School

Addition, subtraction, multiplication, division, and other operations on numbers are referred to as arithmetic operations. The purpose of this study is to ascertain the impact of problem-based learning (PBL) on primary school students’ learning outcomes related to guessing the outcomes of mathematical operations. A quasi-experimental design was used for this study. Class IVC was acquired as the experimental class and class IVB as the control class thanks to the sample selection’s usage of a straightforward random sampling technique. Additionally, SPSS 26 was used to aid in data analysis for this investigation. The data analysis produced the results tcount>ttable, which are 2.423>1.669. If H0 is rejected and H1 is true, then learning through utilizing the model has a large impact. The suggestion of this study put forward to improve learning outcomes in mathematics learning process in elementary schools, specifically on the topic of estimating the results of arithmetics operations.
