Pengaruh Model Pembelajaran Problem Based Instruction (PBI) terhadap Kemampuan Penalaran Matematis Siswa

Abstract

This research was started by the lowerness of students’ mathematical reasoning ability at VII grade of SMPN 1 Kerinci. That’s obtained from the student’s semester examination result then according to the experience, observation and interview results with the junior high school mathematic teachers. The aim of this research is to analyze the effect of Problem Based Instruction (PBI) Model through student’s reasioning ability at VII grade of SMPN 1 Kerinci. This research is using quasy experiment method with Randomized Group Control Only Design. The population is all of seventh grade students in SMPN 1 Kerinci. This research is using Random Sampling Technique that students at VII-C grade as experimental group and VII-A grade as control group. The research instruments in this study is mathematical reasoning ability test to obtain students mathematical reasoning ability. The data is not have normal distribution so that we used Mann Whitney-U test with SPSS helped, obtained Sig (1-tailed). value = 0,000 α = 0,05 so that rejected H0. According to the analyzed of the data, the conclusion obtained that student’s mathematical reasoning ability who learn with using PBI Model is better than using conventional learning.

Mathematical Reasoning Ability of Grade IV Elementary School Students on Polygon Materials

“…The attitude of independence refers to where students no longer rely on information or subject matter provided by teachers, but students themselves can seek from books or other sources. One of the attitudes in solving such problems is the independence of learning to find reasons from various basic knowledge which students give the right decision (Nasution et al, 2020).…”

Peningkatan Kemampuan Pemecahan Masalah Matematis Melalui Model Problem Based Learning dengan Menggunakan Soal-soal Berbasis Budaya Lokal

“…Berdasarkan data penelitian World Bank dalam menunjukkan bahwa rendahnya problem-solving di Indonesia dengan rata-rata persentase 20% yang berdampak tidak baik pada kemampuan pemecahan masalah (Harahap & Nurdalilah, 2020). Hasil studi lain dari PISA (Program for International Student Assessment) pada tahun 2015 menunjukkan bahwa dari 72 negara yang berpartisipasi, Indonesia menempati posisi 64 dengan rata-rata perolehan skor matematika yakni 386 (Nasution et al, 2019). Rendahnya kemampuan matematika di Indonesia menunjukkan lemahnya kemampuan pemecahan masalah matematis siswa Indonesia.…”

How to Design Problem-Based Learning for Reasoning Ability?

“…This can be interpreted that mathematical reasoning skills need to be developed. However, there have been many research results showing that students' low mathematical reasoning was caused by the teacher only providing the subject with examples and routine problem exercises, but when given non-routine questions, students experienced difficulties when they had to start determining the solution (Fuadi et al, 2016;Indriati, 2018;Izzah & Azizah, 2019;Napitupulu et al, 2016;Nasution et al, 2019;Putri et al, 2019;Zubainur et al, 2020). Material that concentrates on non-routine problems is found in material on trigonometry.…”
