Pembelajaran Berbasis Masalah dalam Meningkatkan Kemampuan Pemecahan Masalah Matematika

Abstract

This study aims to improve the learning process and the student’s mathematical problem solving skill by applying Problem Based Learning (PBL) model. This type of research is classroom action research with two cycles. This research was conducted in collaboration between researcher and teacher of mathematics. Subjects were students of class SMPN 9 Pekanbaru. Study was conducted in the odd semester of academic year 2019/2020. The research instrument consists of mathematical learning instruments and instruments to collect data. Mathematical learning instruments used in this study are syllabus, lesson plans, and activity sheets. Data collection instruments used in this study is observation sheets and mathematical problem solving tests. Data analysis technique in this study is analysis descriptive narrative of qualitative data and descriptive statistical analysis of quantitative data. The result of this study showed that the implementation of PBL improved the learning process and the student’s mathematical problem solving skill. The student’s average value in cycle I which is 70,27 had improved to 84,07 in cycle II. The improvement also found in the indicator average value in understanding the problem (94,99), planning a solution (69,71), implementing the pland (82,77), and checking again (54,85). This study concludes that the implementation of PBL improved the student’s mathematical problem solving skill at class SMPN 9 Pekanbaru.

Mathematics Modelling Ability of Students on the Set Materials of VII Class with Problem-Based Learning (PBL)

“…In the Indicator re-checking the occurrence of the indicator is only 8.9%, and is the lowest occurrence indicator, in this indicator only a few students check the results obtained and prove the truth of the results obtained, although they are not complete, some other students do not write answers, based on the results Interviews on indicators re-examine students feel that they are sufficient at the problem-solving stage so that the model obtained is not rewritten to prove whether it is correct, this is in line with research from [16] that other students feel that the results of their work are correct so they don't need to be done. another check.…”

Meningkatkan Kemampuan Pemecahan Masalah Siswa Dengan Menerapkan Model Problem Posing

“…Namun pada kenyataannya kemampuan pemecahan masalah siswa masih rendah. Hal ini sebagaimana terungkap dalam penelitian-penelitian yang dilakukan oleh Gumilang et al (2019), Harahap, (2018, Muhammad et al (2018), Novianti et al (2020), dan Widana (2021). Kondisi yang sama juga dialami oleh para siswa kelas IV di SDN Sadasari III Kabupaten Majalengka.…”

Meningkatkan Hasil Belajar Ekonomi Menggunakan Model STAD

“…Selanjutnya guru berusaha untuk mengulas kembali secara ringkas materi yang berkaitan dengan materi laporan keuangan. Kemudian memberikan lebih banyak tugas agar peserta didik lebih mahir dalam menyelesaikan laporan keuangan (Noviantii, Yuanita, & Maimunah, 2020).…”
