The Influence of Problem-Based Learning Model on the Ability of the Problem of Mathematical Stories

Abstract

The purpose of this study was to determine the effect of problem-based learning models or problem-based learning models on the ability of students to solve mathematical story problems with learning material in space and flat in class 5 Panaragan State Elementary School 1, Bogor City. The approach used in this research is a quantitative approach with a quasi-experimental method. There are several techniques used in this study, namely observation techniques, interview techniques, and tests. Then obtained research results with the average difference in value between the control class and the experimental class, the experimental class has an average value of 73.11, and the control class has an average value of 60.86. After calculating the t-test (One-Sample Test) on the experimental class's post-test value, the Sign value is known. 0.04, because 0.04 <0.05, then Ha is accepted, and H0 is rejected, which shows the influence of PBL models on the ability to solve students' mathematical story problems.

“…Stunting pada anak merupakan masalah gizi kronis karena asupan gizi yang tidak memadai dalam jangka panjang yang dikombinasikan dengan penyakit infeksi pada anak dan masalah lingkungan (UNICEF, 2018). Stunting perlu mendapatkan perhatian khusus karena dapat meningkatkan resiko kematian pada anak, serta menghambat pekembangan fisik dan mental anak (Nurmalasari dkk, 2020). Stunting atau gangguan pertumbuhan linier dapat mengakibatkan anak tidak mampu mencapai potensi genetik, mengindikasi kejadian jangka panjang dan dampak dari ketidakcukupan konsumsi zat gizi, kondisi kesehatan dan pengasuhan yang tidak memadai.…”
